Electricity bills in a certain city have mean $ 106.27 . Assume the bills are normally distributed with standard deviation $ 17.15 . Find the value that separates the lower 40 % of the bills from the rest.
Write only a number as your answer. Round to two decimal places (for example: 42.81). Do not write any units.
Answer:
Step-by-step explanation:
To find the value that separates the lower 40% of the bills from the rest, we need to find the z-score corresponding to the 40th percentile of the standard normal distribution, and then use this z-score to find the corresponding value in the distribution of electricity bills.
Using a standard normal distribution table or a calculator, we can find that the z-score corresponding to the 40th percentile is approximately -0.25.
To find the corresponding value in the distribution of electricity bills, we can use the formula:
z = (x - mu) / sigma
where z is the z-score, x is the corresponding value in the distribution, mu is the mean, and sigma is the standard deviation.
Rearranging this formula to solve for x, we get:
x = mu + z * sigma
Substituting the given values, we get:
x = 106.27 + (-0.25) * 17.15
x = 101.63
Therefore, the value that separates the lower 40% of the electricity bills from the rest is approximately $101.63.

Pedro tracks his steps when he runs. He sets a goal to run exactly 10,000 steps a day on his
running days.
Pedro estimates that there are approximately 2,000 steps in 1 mile. He uses this estimate to
make a plan.
He runs a total of 4 hours over 5 days.
He runs for an equal amount of time each day.
He runs at a rate of 6 miles per hour.
Pedro will not meet his daily running goal with this plan.
What is one change you can make to one value in Pedro's plan to ensure that Pedro meets his
daily running goal? Justify your response.
One change that Pedro can make to his plan to ensure that he meets his daily running goal is to increase the estimated number of steps per mile.
How would this help meet the running goal?If Pedro overestimates the number of steps in a mile, he will end up taking more steps than he initially planned for, which can help him reach his daily goal.
For example, if Pedro increases his estimate from 2,000 steps per mile to 2,500 steps per mile, he will need to run approximately 4 miles per day to reach his goal of 10,000 steps. This will make it more likely for him to reach his daily goal within the 4 hours of running over the 5 days.
Alternatively, Pedro can increase his running speed to cover more distance in a shorter period of time. For instance, if he increases his running speed from 6 miles per hour to 8 miles per hour, he will need to run for only about 2.5 hours per day to reach his goal of 10,000 steps.

A corn plant will be killed by the aphids if the total number of aphids on the plant exceeds 2,000. If there are 50 corn plants in this field, will there be enough aphids after 3 weeks to completely destroy the plants?
There won't be enough aphids to completely harm the maize plants because 10,000 is less than 2,000 50 (the maximum number of aphids that can be on all the plants without killing them).
Application of linear equationTo determine if there are enough aphids to kill the corn plants, we need to know the total number of aphids on each plant after 3 weeks. Let's assume that on average, each plant has 200 aphids after 3 weeks.
Then, the total number of aphids in the field would be:
50 plants × 200 aphids/plant = 10,000 aphids

Angel 270 and radius 12
Therefore, the length of the arc intercepted by the central angle is 56.52 cm (rounded to two decimal places).
What is arc?In geometry, an arc is a part of a circle. Specifically, it is a portion of the circumference of a circle. An arc can be defined by two endpoints and all the points on the circle's circumference between those endpoints. Arcs are commonly measured in degrees, just like angles. A full circle has 360 degrees, so a semicircle has 180 degrees, and so on. The length of an arc depends on the size of the circle and the size of the central angle that intercepts it. Arcs are important in many applications of geometry, such as in navigation, architecture, and engineering. They are also used in trigonometry and calculus to study functions that involve circular or periodic behavior.
Here,
We can use the formula for the length of an arc of a circle to find the length of the arc intercepted by a central angle. The formula is:
Length of arc = (Central angle / 360) x (2 x π x radius)
where π (pi) is a mathematical constant approximately equal to 3.14.
In this case, the central angle measures 270 degrees and the radius of the circle is 12 cm. We can substitute these values into the formula to get:
Length of arc = (270 / 360) x (2 x π x 12)
Length of arc = (3/4) x (2 x 3.14 x 12)
Length of arc = 0.75 x 75.36
Length of arc = 56.52 cm

Therefore, the area of the base of the aquarium is 5760 square centimeters.
What is area?Area is a measure of the amount of space inside a two-dimensional (2D) shape or figure. It is usually measured in square units, such as square meters (m²) or square centimeters (cm²). The area of a shape is calculated by multiplying the length of one side or dimension of the shape by the length of another side or dimension. The resulting value represents the total number of square units that are contained within the shape. Area is an important concept in mathematics and is used in various fields, such as geometry, physics, and engineering. It helps in measuring and comparing the sizes of shapes and figures, and in determining how much material is needed to cover or fill a certain area.
Here,
The area of the base can be calculated using the dimensions of the aquarium.
Let's assume that the aquarium has a rectangular base with length L, width W, and height H. Then, the area of the base of the aquarium can be calculated as:
Area of base = Length x Width = L x W
If Monica measured the length and width of the base, we can use those measurements to calculate the area of the base. If not, we'll need to make additional assumptions or measurements.
Assuming we have the length and width of the base, we can calculate the area as follows:

For Saturday matinees, a movie theater charges $5 for adult tickets and $3 for children's tickets. If the movie theater sold a total of 166 matinee tickets and made
$718 in revenue on Saturday afternoon, how many adult matinee tickets were sold?
Answer:
Let's use A to represent the number of adult tickets sold and C to represent the number of children's tickets sold.
We know that A + C = 166, since the total number of tickets sold is 166.
We also know that the revenue earned from adult tickets is $5A and the revenue earned from children's tickets is $3C. Since the total revenue earned is $718, we can write:
5A + 3C = 718
Now we have two equations with two variables:
A + C = 166
5A + 3C = 718
We can solve for A in the first equation to get:
A = 166 - C
Then we can substitute this expression for A into the second equation:
5(166 - C) + 3C = 718
Simplifying and solving for C, we get:
830 - 2C = 718
2C = 112
C = 56
So 56 children's tickets were sold. We can substitute this value back into the first equation to solve for A:
A + 56 = 166
A = 110
Therefore, 110 adult tickets were sold.
Answer:
Step-by-step explanation:
Let's use the following variables:
a = number of adult tickets sold
c = number of children tickets sold
We know that:
a + c = 166 (total number of tickets sold)
5a + 3c = 718 (total revenue)
We can solve this system of equations by substitution or elimination. Here, we'll use elimination:
Multiply the first equation by 3: 3a + 3c = 498
Subtract the second equation from the first: 2a = 220
Solve for a: a = 110
So 110 adult tickets were sold. We can find the number of children's tickets by substituting a = 110 into either of the original equations:
c = 166 - a = 166 - 110 = 56
Therefore, 110 adult tickets and 56 children's tickets were sold.

The whole distance around a shape is referred to as its perimeter. In essence, the length of any shape when it is expanded in a linear form equals its perimeter. A shape's perimeter in a two-dimensional plane is its complete circumference. Depending on their measurements, distinct shapes' perimeters may be equal in length. Units are used to measure perimeter (m, cm, in, feet, etc.)
From the question;
The lengths of all the sides must be added up in order to determine the shape's perimeter.
Let's begin by giving the shape's vertices the following labels:
A = (2, 0)
B = (4, 0)
C = (4, 3)
D = (3, 4)
E = (2, 3)
The lengths of each side can be determined using the distance formula:
AB = = = 2
BC =
CD =
DE =
EA =
AB + BC + CD + DE + EA =
As a result, the shape has a perimeter of units.

Step-by-step explanation:
1. An advertising agency finds that of its 200 clients, 150 use television (T), 80 use magazines (M), and 50 use both. a. clients. Use these data to complete a Venn diagram displaying the use of mass media for these 200 b. Use your Venn diagram to determine the following probabilities: i. P(T) ii. P(T^M) iii. P(TUM) P(T|M)
By using Venn diagram the following probabilities are 0.75,0.25,0.9 and 0.625.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
We are given that;
Number of clients= 200
Number of television= 150
Magazines=80
Both magazine and television=50
Now,
To complete the diagram, we can fill in the following values:
The size of T is 150.
The size of M is 80.
The size of TM (the overlap between T and M) is 50.
The size of C (the total number of clients who use either T or M) is 150 + 80 - 50 = 180.
The size of U (the number of clients who use neither T nor M) is 200 - 180 = 20.
Now we can use the Venn diagram to answer the following probabilities:
i. P(T) is the probability that a randomly selected client uses television. This is the size of T divided by the total number of clients, which is 150/200 = 0.75.
ii. P(T ∩ M) is the probability that a randomly selected client uses both television and magazines. This is the size of TM divided by the total number of clients, which is 50/200 = 0.25.
iii. P(T ∪ M) is the probability that a randomly selected client uses either television or magazines (or both). This is the size of C divided by the total number of clients, which is 180/200 = 0.9.
iv. P(T|M) is the probability that a randomly selected client uses television given that they use magazines. This is the size of TM divided by the size of M, which is 50/80 = 0.625.
Therefore, by probability the answer will be 0.75,0.25,0.9 and 0.625.

14. The number of visitors to a system of county parks t years after 2010 can be modeled by A =20.6(1.03)', where A is the annual number of visitors in thousands. Find and interpret the constant
percent rate of change per unit interval in the context of the situation.
The constant percent rate of change per unit interval is approximately 0.0305 or 3.05%.
What is the exponential functions?
An exponential function is a mathematical function of the form:
[tex]f(x) = a^x[/tex]
The given formula for the number of visitors to the county parks system is:
[tex]A = 20.6(1.03)^t[/tex]
where t is the number of years after 2010 and A is the number of visitors in thousands.
To find the constant percent rate of change per unit interval, we can take the derivative of A with respect to t:
[tex]dA/dt = 20.6(1.03)^t * ln(1.03)[/tex]
The constant percent rate of change per unit interval is given by the expression:
r = (dA/dt) / A
Substituting the values of dA/dt and A, we get:
[tex]r = [20.6(1.03)^t * ln(1.03)] / [20.6(1.03)^t]\\r = ln(1.03)\\r = 0.0305[/tex]
Hence, the constant percent rate of change per unit interval is approximately 0.0305 or 3.05%.

Which of the
following points
would be a solution
to this system of
linear inequalities?
y≤-3x-2
y> x-2
(-4,1)
(2, 2)
Neither of the given points is a solution to the system of linear inequalities.
What does solution to the system of linear inequalities mean ?
A system of linear inequalities is a set of two or more linear inequalities with the same variables. This system consists of two linear inequalities, each involving the variables x and y, and each inequality uses one of the inequality symbols.
The solution to a system of linear inequalities is the set of values for the variables that satisfy all the inequalities in the system simultaneously. This solution can be represented graphically as the region of the coordinate plane that satisfies all the inequalities in the system.
Check the given points whether they are solutions to the system of linear inequalities or not :
Substitute the x and y values of each point into both inequalities and check if they are true.
(a) (-4,1) :
y ≤ -3x - 2
1 ≤ -3(-4) - 2
1 ≤ 10
This is false, so (-4,1) is a not solution to the first inequality.
y > x - 2
1 > -4 - 2
1 > -6
This is true, so (-4,1) is a solution to the second inequality.
Since (-4,1) is a solution to only one of the inequalities and not both, it is not a solution to the system of linear inequalities.
(b) (2,2):
y ≤ -3x - 2
2 ≤ -3(2) - 2
2 ≤ -8
This is false, so (2,2) is not a solution to the first inequality.
y > x - 2
2 > 2 - 2
2 > 0
This is true, so (2,2) is a solution to the second inequality.
Since (2,2) is a solution to only one of the inequalities and not both, it is not a solution to the system of linear inequalities.
Therefore, neither of the given points is a solution to the system of linear inequalities.
