In 2010, a total of 2187 of the employees at
Leo's company owned a petrol car.
In 2013, there were 1536 employees with
petrol cars.
Assuming this number decreases
exponentially, work out how many employees
owned a petrol car in 2019.
Give your answer to the nearest integer.
we can expect that approximately 815 employees owned a petrol car in 2019 (rounded to the nearest integer).
How to solve exponential function?We can model the number of employees owning petrol cars in the years 2010 and 2013 using the exponential decay formula:
[tex]$$N(t) = N_0 e^{-kt}$$[/tex]
where N(t) is the number of employees owning petrol cars at time t, [tex]$N_0$[/tex] is the initial number of employees owning petrol cars (in 2010), k is the decay constant, and t is the time elapsed since 2010 (in years).
We can use the given information to find the value of k:
In 2013 (3 years after 2010), the number of employees owning petrol cars decreased from 2187 to 1536:
[tex]$$1536 = 2187 e^{-3k}$$[/tex]
Dividing both sides by 2187 gives:
[tex]$$e^{-3k} = \frac{1536}{2187}$$[/tex]
Taking the natural logarithm of both sides gives:
[tex]$$-3k = \ln\left(\frac{1536}{2187}\right)$$[/tex]
Solving for k gives:
[tex]$k = -\frac{1}{3} \ln\left(\frac{1536}{2187}\right) \approx 0.1565$$[/tex]
Now we can use the exponential decay formula to find the number of employees owning petrol cars in 2019 (9 years after 2010):
[tex]$$N(9) = 2187 e^{-0.1565 \cdot 9} \approx 815$$[/tex]
Therefore, we can expect that approximately 815 employees owned a petrol car in 2019 (rounded to the nearest integer).

What is area?The area of a circle is a measure of the size of the surface of the circle. It is calculated by multiplying the radius of the circle (the length from the center of the circle to its edge) by itself, and then multiplying the result by the constant pi (3.14). The formula for calculating the area of a circle is A = πr2, where “A” represents the area, “π” is pi, and “r” is the radius of the circle.
The radius of the circle, r, can be determined by the Pythagorean theorem. Since AC = 36 cm and AP = 6 cm, the hypotenuse of the right triangle formed by AC and AP is the radius of the circle, r. By applying the Pythagorean theorem, we get:

Since the range of observed values is 1, which is less than two standard deviations away from 10, the observed value is not significantly different from the expected value and thus the number of girls in 10 births is not significantly low.
What is standard deviation?Standard deviation is a measure of how spread out numbers are in a data set. It is calculated by taking the square root of the variance. Variance is the average of the squared differences from the mean. Standard deviation provides an indication of how much variation there is in the data set, and is often used in statistical analysis.
The range rule of thumb is a statistical method used to determine whether a given phenomenon is significantly different from an expected value. It states that if the range of observed values is greater than two standard deviations of the expected value, then the observed values are significantly different from the expected value.
In this particular case, the expected value is 10 girls in 10 births, and the observed value is 1 girl in 10 births. Since the range of observed values is 1, which is less than two standard deviations away from 10, the observed value is not significantly different from the expected value and thus the number of girls in 10 births is not significantly low.

The lengt of a rectangle is 8 meters more that the width. If the area of the rectangle is 65 square meters, find the width
The width of the rectangle is 5 meters.
To find the width of the rectangle, let's use the formula for the area of a rectangle, which is:
Area = length x width
We know that the area of the rectangle is 65 square meters. We also know that the length of the rectangle is 8 meters more than the width. Let's call the width "w". Then, the length can be expressed as:
length = w + 8
Substituting this expression for length into the formula for the area, we get:
65 = (w + 8) x w
Simplifying and solving for w, we get:
w² + 8w - 65 = 0
Using the quadratic formula, we get:
w = (-8 ± √(8² + 4(1)(65))) / (2(1))
w = (-8 ± √(324)) / 2
w = (-8 ± 18) / 2
We take the positive value for w since the width cannot be negative:
w = (-8 + 18) / 2

Answer:
Step-by-step explanation:
the yearly rainfall of a town, recorded since records began, is normally distributed with a mean of 95 centimeters and a standard deviation of 28 centimeters. in what percentage of years will the rainfall be between 50 and 70 centimeters in that town?
In approximately 11.41% of years, the rainfall will be between 50 and 70 centimeters in that town.
To solve this problem, we need to find the percentage of years where the rainfall is between 50 and 70 centimeters. We can do this by standardizing the rainfall values and using a standard normal distribution table.
First, we need to standardize the rainfall values of 50 and 70 centimeters using the formula
z = (x - μ) / σ
where
z is the standardized value
x is the rainfall value
μ is the mean
σ is the standard deviation
For x = 50
z = (50 - 95) / 28
z = -1.607
For x = 70
z = (70 - 95) / 28
z = -0.893
Next, we use a standard normal distribution table or calculator to find the area under the curve between these two standardized values. This represents the percentage of years where the rainfall is between 50 and 70 centimeters.
Using a standard normal distribution table, we can find that the area under the curve between z = -1.607 and z = -0.893 is 0.1141. This means that approximately 11.41% of years will have rainfall between 50 and 70 centimeters in this town.

a horizontal curve is to be designed with a 2000 feet radius. the curve has a tangent length of 400 feet and its pi is located at station 103 00. determine the stationing of the pt.
A horizontal curve is to be designed with a 2000 feet radius. The curve has a tangent length of 400 feet and its pi is located at station 103+00. Determine the stationing of the PT.
A horizontal curve is a curve that is used to provide a transition between two tangent sections of a roadway. To connect two tangent road sections, horizontal curves are used. Horizontal curves are defined by a radius and a degree of curvature. The curve's radius is given as 2000 feet. The tangent length is 400 feet.
The pi is located at station 103+00.
To determine the stationing of the PT, we must first understand what the "pi" means. PC or point of curvature, PT or point of tangency, and PI or point of intersection are the three primary geometric features of a horizontal curve. The point of intersection (PI) is the point at which the back tangent and forward tangent of the curve meet. It is an important point since it signifies the location of the true beginning and end of the curve. To calculate the PT station, we must first determine the length of the curve's arc. The formula for determining the length of the arc is as follows:
L = 2πR (D/360)Where:
L = length of the arc in feet.
R = the radius of the curve in feet.
D = the degree of curvature in degrees.
PI (103+00) indicates that the beginning of the curve is located 103 chains (a chain is equal to 100 feet) away from the road's reference point. This indicates that the beginning of the curve is located 10300 feet from the road's reference point. Now we need to calculate the degree of curvature
:Degree of curvature = 5729.58 / R= 5729.58 / 2000= 2.8648 degrees. Therefore, the arc length is:
L = 2πR (D/360)= 2π2000 (2.8648/360)= 301.6 feet.
The length of the curve's chord is equal to the length of the tangent, which is 400 feet. As a result, the length of the curve's long chord is: Long chord length = 2R sin (D/2)= 2 * 2000 * sin(2.8648/2)= 152.2 feet To determine the stationing of the PT, we can use the following formula: PT stationing = PI stationing + Length of curve's long chord= 10300 + 152.2= 10452.2Therefore, the stationing of the PT is 10452+2.

Aron needs 5/7 of a yard of fabric to cover a chair ad 2/3 of a yard of the fabric to cover a footstool. How much more fabric is required for the chair than the footstool?
Answer:
Step-by-step explanation:
To find out how much more fabric is required for the chair than the footstool, we need to subtract the amount of fabric required for the footstool from the amount of fabric required for the chair.
The amount of fabric required for the chair is 5/7 of a yard.
The amount of fabric required for the footstool is 2/3 of a yard.
So to find the difference, we need to subtract:
5/7 - 2/3
To do this, we need to find a common denominator, which is 21 in this case. We get:
(15/21) - (14/21) = 1/21
Therefore, Aron needs 1/21 more yard of fabric to cover the chair than the footstool.
g a group of people were asked if they had run a red light in the last year. responded yes, and responded no. find the probability that if a person is chosen at random, they have run a red light in the last year.
The probability that a person chosen at random has run a red light in the last year can be calculated by taking the number of people who said “yes” to running a red light and dividing it by the total number of people in the group.
For example, if 10 people said “yes” and 20 said “no”, the probability of a person chosen at random running a red light in the last year is 10/30, or 1/3.
The probability of an event happening is calculated using the formula:
Probability = Number of Favorable Outcomes / Total Number of Outcomes
In this case, the favorable outcome is running a red light in the last year, and the total number of outcomes is the total number of people asked.
To calculate the probability, we take the number of people who said “yes” to running a red light in the last year and divide it by the total number of people in the group. In our example, 10/30 = 1/3, so the probability that a person chosen at random has run a red light in the last year is 1/3.
In conclusion, the probability of a person chosen at random having run a red light in the last year is calculated by taking the number of people who responded “yes” and dividing it by the total number of people in the group.

a group of friends wants to go to the amusement park. they have no more than $480 to spend on parking and admission. parking is $8.75, and tickets cost $15.50 per person, including tax. which inequality can be used to determine p, the maximum number of people who can go to the amusement park?
Therefore, the inequality that can be used to determine p, the maximum number of people who can go to the amusement park, is p ≤ 30.
What do you mean by inequalities?In mathematics, inequalities are statements that compare two values or expressions and indicate whether they are equal, greater than, or less than each other. An inequality is typically represented by a symbol, such as "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), or "≠" (not equal to).
Given by the question.
Let's assume that the maximum number of people that can go to the amusement park is p. The cost of parking is $8.75, and the cost of admission for each person is $15.50.
Then, the total cost for p people can be calculated as:
Total cost = (Cost of parking) + (Cost of admission per person x number of people)
Total cost = $8.75 + $15.50p
The group has no more than $480 to spend, so we can set up an inequality:
Total cost ≤ $480
$8.75 + $15.50p ≤ $480
Subtracting $8.75 from both sides:
$15.50p ≤ $471.25
Dividing both sides by $15.50:
p ≤ 30.35
Since the number of people cannot be a decimal, we round down to the nearest whole number: p ≤ 30.

(Simplify your answer. Type an equation. Type your answer in point-slope form. Use integers or fractions for any numbers in the equation)
The equation of the line in slope-intercept form is y = 6x + 55.
Describe Equation?Equations can involve variables, which are placeholders for unknown values that we wish to find. For example, the equation x + 3 = 7 asserts that the value of x plus 3 is equal to 7. We can solve for x by subtracting 3 from both sides of the equation, obtaining x = 4.
Equations can be linear or nonlinear, and they can involve one or more variables. They can be represented in various forms, such as standard form, slope-intercept form, or quadratic form.
To find the equation of the line in point-slope form, we need to first find the slope of the line. We can use any two points from the table to find the slope using the formula:
slope = (change in y)/(change in x)
Let's use the first and last points in the table:
slope = (295 - 175)/(40 - 20) = 120/20 = 6
Now we can use the point-slope form of the equation of a line:
y - y1 = m(x - x1)
where m is the slope and (x1, y1) is any point on the line. Let's use the first point (20, 175):
y - 175 = 6(x - 20)
To write this equation in slope-intercept form, we need to isolate y:
y - 175 = 6x - 120
y = 6x + 55
So the equation of the line in slope-intercept form is y = 6x + 55.

In a right triangle, the tangent of an acute angle is defined as the ratio of the length of the opposite side to the length of the adjacent side. Let us label the sides of the right triangle as follows:
The hypotenuse (the longest side) is 26
One of the acute angles (let's call it angle A) has opposite side length of 10
The other acute angle (let's call it angle B) has opposite side length of 24
To find the tangent of the larger acute angle, which is angle B, we use the formula:
tan(B) = opposite / adjacent
In this case, the opposite side of angle B is 24, and the adjacent side is 10. So we have:
tan(B) = 24 / 10 = 2.4
Therefore, the tangent of the larger acute angle (angle B) is 2.4.
This means that if we draw a line that is tangent to the circle with radius 10 centered at the vertex of angle B, the length of that line will be 24. This is a geometric interpretation of the tangent function, where the tangent of an angle is the length of a line tangent to the unit circle at that angle.
In conclusion, we have found that in the given right triangle with sides 10, 24, and 26, the tangent of the larger acute angle (angle B) is 2.4.

Help me find the slope of the line and it’s ok if you don’t know all of them
Slope of each graph are [tex]\frac{6}{5}[/tex],[tex]\frac{-1}{3}[/tex] and 1 respectively.
What is a Slope?Slope of a line in mathematics is defined as the ratio of the change in the y coordinate w.r.t the change in the x coordinate.
Both the change in the y-coordinate and the net change in the x-coordinate are denoted by y₂-y₁ and x₂-x₁, respectively.
Thus, the formula for the change in y-coordinate with regard to the change in x-coordinate is
m=y₂-y₁/ x₂-x₁
In the figure 1Taking two points as per observation
Point1: (x₁ y₁)=(0,-3)
Point2:(x₂, y₂)=(5/2,0)
Slope of line=y₂-y₁/ x₂-x₁
=[tex]\frac{0+3}{5/2-0}[/tex]
=[tex]\frac{6}{5}[/tex]
In the figure2Taking two points as per observation
Point1: (x₁ y₁)=(0,3)
Point2:(x₂, y₂)=(2,2)
Slope of line=y2-y1/x2-x1
=[tex]\frac{2-3}{2-0}[/tex]
=-⅓
In the figure 3Taking two points as per observation
Point1: (x₁ y₁)=(-2,0)
Point2:(x₂, y₂)=(0,2)
Slope of line=y2-y1/x2-x1
=[tex]\frac{2-0}{0+2}[/tex]
=1
Hence, Slope of each graph are 6/5,-⅓ and 1 respectively.

has 37 coins, all nickels and dimes in his piggy bank. the value of the coins is $3.10. how many dimes does carter have?
Carter has 13 dimes in his piggy bank
To solve this equation, we need to use the distributive property to simplify the equation:
(x dimes x 10 cents) + (37-x nickels x 5 cents) = $3.10
We can then solve for the number of dimes by isolating the dimes on one side of the equation:
x dimes x 10 cents = $3.10 - (37-x nickels x 5 cents),By dividing both sides of the equation by 10 cents, we can solve for the number of dimes, x:
x dimes = ($3.10 - (37-x nickels x 5 cents)) / 10 cents
Plugging in the value of 37 coins and solving the equation, we get:
x dimes = (3.10 - (37 -x nickels x 5 cents)) / 10 cents
x dimes = (3.10 - 185 + 5x) / 10 centsx dimes = (3.10 - 180) / 10 centsx dimes = 1.30 / 10 centsx dimes = 13 dimes
Therefore, Carter has 13 dimes in his piggy bank.

Define The Fundamental Counting Principle: Unit 2: Probability Lesson 2: Counting Our Way to Probabilities Describe what it means to count with replacement and without replacement: You need a new password for an email account. The requirements are that the password needs to be 8 characters long considering of 5 lowercase letters followed by 3 numbers. If you are allowed to use characters more than once (with replacement), how many different possibilities are there for a password? (Use an image to help you understand). Let's use the same example as above, only this time you may only use each letter or number one time. That is without replacement or repetition.
Similarly, there are 10 choices for the first number, 9 choices for the second number, and 8 choices for the third number. Therefore, the total number of possibilities is[tex]26 × 25 × 24 × 23 × 22 × 10 × 9 × 8 = 14,776,320[/tex] possibilities.
Fundamental Counting Principle and how to count with and without replacement.The Fundamental Counting Principle (FCP) states that if there are m ways to perform an event and n ways to perform a second event, then there are m × n ways to perform both events. For example, suppose there are 2 shirts, 3 pants, and 4 pairs of shoes in your closet. Using the FCP, you can calculate the number of outfit combinations: 2 × 3 × 4 = 24.If you are allowed to use characters more than once (with replacement), the number of different possibilities for a password can be calculated by multiplying the number of choices for each character type. There are 26 lowercase letters, so there are 26 choices for the first letter, 26 choices for the second letter, and so on. Similarly, there are 10 digits, so there are 10 choices for each number.
Therefore, the total number of possibilities is [tex]26 × 26 × 26 × 26 × 26 × 10 × 10 × 10 = 26^5 × 10^3 = 11,881,376,000[/tex] possibilities.If you may only use each letter or number one time, then you cannot repeat any choices. Therefore, the number of possibilities is reduced. There are 26 choices for the first letter, 25 choices for the second letter (since one has already been used), and so on.

Two cubes are placed together to form a solid so that one of side of the first cube completely matches up with one side of the second cube. Each cube has a side length of 5 m.
What is the total surface area of the solid?
Enter your answer in the box.
250 is the total surface area of the solid.
How do you determine surface area?
The whole surface of a three-dimensional form is referred to as its surface area. The surface area of a cuboid with six rectangular faces may be calculated by adding the areas of each face.
Instead, you may write out the cuboid's length, width, and height and apply the formula surface area (SA)=2lw+2lh+2hw.
Each side of a cube with side length = 5 has an area of 25; the overall area is 6 x 25 = 150
A cube with sides of length 5 has an area of 25 on each side, making its overall area 6 x 25 or 150.
Both have a combined area of 150 + 150 = 300
300 - 25 - 25 = 250 is the result from each of the two cubes.

each page number of a 488-page book is printed one time in the book. the first page is page 1 and the last page is page 488. when printing all of the page numbers, how many more 4's are printed than 8's?
the number of more 4's printed than 8's is 188 - 59 = 129.
We can approach this problem by counting the number of times the digit 4 appears and the number of times the digit 8 appears in the page numbers from 1 to 488.
First, let's count the number of times the digit 4 appears. We can break down the counting into three cases:
The digit 4 appears in the units place (page numbers 4, 14, 24, ..., 484): there are 49 such page numbers (from 4 to 484, incrementing by 10).
The digit 4 appears in the tens place (page numbers 40 to 49, 140 to 149, ..., 440 to 449): there are 50 such page numbers.
The digit 4 appears in the hundreds place (page numbers 400 to 488): there are 89 such page numbers.
Thus, the total number of times the digit 4 appears is 49 + 50 + 89 = 188.
Next, let's count the number of times the digit 8 appears. We can break down the counting into two cases:
The digit 8 appears in the tens place (page numbers 80 to 89, 180 to 189, ..., 480 to 489): there are 50 such page numbers.
The digit 8 appears in the hundreds place (page numbers 800 to 880): there are 9 such page numbers.
Thus, the total number of times the digit 8 appears is 50 + 9 = 59.
Therefore, the number of more 4's printed than 8's is 188 - 59 = 129.

jason flips a coin three times. what is the probability that the coin will land on the same side in all three tosses?
The probability that the coin will land on the same side in all three tosses is 1/8.
There are two possible outcomes for each coin flip: heads or tails. Therefore, there are 2 × 2 × 2 = 8 possible outcomes for flipping a coin three times in a row.To find the probability that the coin will land on the same side in all three tosses, we need to count the number of outcomes that satisfy this condition.
There are only two such outcomes: either all three tosses are heads or all three tosses are tails. Therefore, the probability of this happening is 2/8 or 1/4.But we are asked for the probability that the coin will land on the same side in all three tosses, not just one specific side.
Therefore, we need to divide our previous result by 2 (the number of sides of the coin) to get the final answer: 1/4 ÷ 2 = 1/8. The probability that the coin will land on the same side in all three tosses is 1/8.
