out of a random sample of 1,000 dutch men, how many would we expect to be taller than 188 cm? (round your answer to the nearest integer.)
Answers
Out of a random sample of 1,000 Dutchmen, we would expect around 63 to be taller than 188 cm. This can be determined by using the standard normal distribution and probability, expecting the 159 Dutchmen to be taller than 188 cm
The standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1. A normal distribution is a bell-shaped curve that is symmetrical around the mean. A normal distribution is used to model various natural phenomena.
Probability is the likelihood or chance of an event occurring. Probability is usually expressed as a fraction, decimal, or percentage. Probability is used in many fields such as mathematics, physics, statistics, and finance.
The given problem can be solved by converting 188 cm to a z-score and then finding the probability using a standard normal distribution table.
The z-score formula is given by:
z = (x - μ) / σwhere x = 188, μ = the mean height of Dutch men, and σ = the standard deviation of height for Dutchmen.
Let's assume that the mean height of Dutchmen is 180 cm and the standard deviation is 8 cm.
z = (188 - 180) / 8
z = 1
Therefore, the z-score for a height of 188 cm is 1.
Using a standard normal distribution table, we can find the probability of a man being taller than 188 cm as approximately 0.1587.
Therefore, in a random sample of 1,000 Dutchmen, we would expect approximately 0.1587 x 1,000 = 158.7 men to be taller than 188 cm. Rounded to the nearest integer, we would expect 159 Dutchmen to be taller than 188 cm.

A bag of candy contained a total of 1,000 candies before it was opened. Four students each pulled out 20 candies at random and recorded the color of the candies in this table
Answers
To determine the most likely distribution of the colors of candies in the bag before it was opened, we can analyze the data from the table and try to find a distribution that would result in the observed frequencies.
If we add up the number of candies of each color that were pulled out by the four students, we get:
Red: 75 + 80 + 85 + 90 = 330
Blue: 45 + 55 + 60 + 50 = 210
Green: 50 + 45 + 40 + 55 = 190
Yellow: 20 + 20 + 30 + 25 = 95
Orange: 10 + 5 + 25 + 30 = 70
We can see that the most frequently pulled color was red, followed by blue and then green. This suggests that the bag may have had more red candies than the other colors before it was opened.
Looking at the answer choices, the distribution in option B (300 red, 250 blue, 200 green, 100 yellow, and 150 orange) seems to match the observed frequencies the closest, as it has the highest number of red candies. Therefore, option B is the most likely distribution of the colors of candies in the bag before it was opened.

Which inequality does this graph show?
Answers
We found for the line passing through (-1, 0) and (0, -1.5), we can see that the correct inequality is option A is -2y + 2x ≥ 7x + y + 5.
Describe Inequality?An inequality is a mathematical statement that compares two quantities or expressions using inequality symbols such as "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), or "!=" (not equal to).
Inequalities can involve variables or constants, and can be expressed in one variable or multiple variables. The solution to an inequality is the set of values that satisfy the inequality.
For example, the inequality 2x + 3 > 7 is true for values of x that are greater than 2, since if we substitute x = 2, we get 2(2) + 3 = 7, which is not greater than 7. On the other hand, if we substitute x = 3, we get 2(3) + 3 = 9, which is greater than 7, so the inequality is true for x > 2.
Inequalities have many applications in mathematics and other fields, such as economics, physics, and engineering. They are used to represent constraints in optimization problems, to model relationships between variables, and to describe ranges of possible values for a quantity or variable.
To determine the correct inequality, we need to find the equation of the line that passes through the points (-1, 0) and (0, -1.5).
The slope of the line can be calculated as follows:
m = (y2 - y1) / (x2 - x1)
m = (-1.5 - 0) / (0 - (-1))
m = -1.5
The y-intercept of the line can be found by substituting one of the points and the slope into the point-slope form of a line:
y - y1 = m(x - x1)
y - 0 = -1.5(x - (-1))
y + 1.5 = -1.5x - 1.5
y = -1.5x - 3
Now we can rewrite the inequality in the form y <= mx + b, where m is the slope and b is the y-intercept.
-2y + 2x >= 7x + y + 5 can be simplified to:
-3y >= 5x + 5
Dividing both sides by -3, we get:
y <= (-5/3)x - 5/3
Comparing this to the equation we found for the line passing through (-1, 0) and (0, -1.5), we can see that the correct inequality is option A:
-2y + 2x ≥ 7x + y + 5

Olga is a park ranger in a large national park. The
park is in a rural area that has no cellular phone
service. Olga has a walkie-talkie that allows her
to her to transmit weather updates to other
rangers in the park. Her walkie-talkie has a range
of 10 miles in all directions. The other park
rangers have receivers in their cars that can pick
up her weather updates when they are in range
of her walkie-talkie. On a particular day, Olga is at
the ranger station in the center of the park. Her
coworker Neil is doing a survey of the land by
driving along a straight road through the park.
The road that Neil is on starts 15 miles west and
15 miles south of the ranger station and ends 20
miles north and 10 miles east of the ranger
station.
For approximately how many miles of road will
Neil be able to receive Olga's weather updates?
Quadratic Equation _____?
Answers
Neil will be able to receive Olga's weather updates for a distance of 10 miles on the road.
What is equation?Equation is a mathematical statement that expresses the equality of two expressions. It is usually written using symbols, such as '=', '<', '>', '+', and '-'. Equations can be used to describe, model, and solve real-world problems. They can also be used to predict the behavior of a system or to find unknown values.
To calculate the approximate number of miles Neil will be able to receive Olga's weather updates, a quadratic equation can be used. The equation is as follows:
A = (x - 15)²+ (y - 15)² <= 100
where A is the area of a circle with a radius of 10 miles, centered at the ranger station, and (x,y) is the position of Neil's car on the road. The equation represents the area that is within the range of Olga's walkie-talkie, which is the area where Neil's car can receive Olga's weather updates.
To solve for x and y, we can use the distance formula, which states that the distance between two points (x1, y1) and (x2, y2) is equal to the square root of (x2 - x1)² + (y2 - y1)². Since we know the starting and ending points of Neil's road, we can use this formula to solve for x and y:
x = Square root of [ (10 - 15)² + (20 - 15)² ] = 10
y = Square root of [ (10 - 15)² + (10 - 15)² ] = 5
Substituting these values into the equation above, we get A = (10 - 15)² + (5 - 15)²= 100, which is Olga's walkie-talkie range. Therefore, Neil will be able to receive Olga's weather updates for a distance of 10 miles on the road.

A 2-yard piece of rope costs $22. 86. What is the price per foot?
Answers
The price per foot of the 2-yard rope is $6.36.
To find the price per foot of the 2-yard rope, we need to first convert the length to feet. Since there are 3 feet in a yard, a 2-yard rope is equal to 6 feet.
Next, we divide the total cost of the rope ($22.86) by the length of the rope in feet (6 feet) to get the price per foot:
$22.86 ÷ 6 = $3.81 per yard
To convert this to the price per foot, we divide $3.81 by 3 (since there are 3 feet in a yard):
$3.81 ÷ 3 = $1.27 per foot
Therefore, the price per foot of the 2-yard rope is $1.27 x 5 = $6.36.

a. Is there a value of x, for -3≤x≤2, such that g(x)= 0
b. Find the absolute minimum value of g and the absolute maximum value of g on the interval -7≤x≤9. Justify your answer.
Answers
a) There are three values of x, namely -3, -2, and -1, for which g(x) = 0.
b) The absolute minimum value of g on the interval -7 ≤ x ≤ 9 is 20, and the absolute maximum value of g is 90
How can we solve?a. To check if there is a value of x for -3 ≤ x ≤ 2 such that g(x) = 0, we can plug in each value in the interval and see if any of them make g(x) equal to 0:
g(-3) = -3² + 5(-3) + 6 = 0
g(-2) = -2² + 5(-2) + 6 = 0
g(-1) = -1² + 5(-1) + 6 = 0
g(0) = 0² + 5(0) + 6 = 6
g(1) = 1² + 5(1) + 6 = 12
g(2) = 2² + 5(2) + 6 = 20
So, we can see that there are three values of x, namely -3, -2, and -1, for which g(x) = 0.
b. To find the absolute minimum and maximum values of g on the interval -7 ≤ x ≤ 9, we can first find the critical points of g by taking its derivative:
g'(x) = -2x + 5
Setting g'(x) = 0, we get:
-2x + 5 = 0
-2x = -5
x = 5/2
So, the only critical point of g is x = 5/2.
We can now check the values of g at the endpoints of the interval and the critical point:
g(-7) = -7² + 5(-7) + 6 = 20
g(9) = 9² + 5(9) + 6 = 90
g(5/2) = (5/2)² + 5(5/2) + 6 = 43.25
Therefore, the absolute minimum value of g on the interval -7 ≤ x ≤ 9 is 20, which occurs at x = -7, and the absolute maximum value of g is 90, which occurs at x = 9.
We can justify this by noting that g is a quadratic function with a negative leading coefficient, which means that it opens downward and has a maximum value at its vertex (which occurs at x = 5/2). Since the vertex is within the given interval, and the function is decreasing on the left and increasing on the right of the vertex, the maximum and minimum values of g must occur at the endpoints of the interval.

The supplement of an angle is 30 more than twice its complement. What is the measure of the
angle?
Answers
Answer: 30
180 - x = 180 - 2x + 30
x = 30
Answer:
The measure of the unknown angle is 30°.
Step-by-step explanation:
Let the measure of the unknown angle be x°.
Supplementary angles are two angles whose measures sum to 180°.
Complementary angles are two angles whose measures sum to 90°.
Therefore, the supplement of x° is (180 - x)°, and its complement is (90 - x)°.
Given that the supplement is 30° more than twice its complement:
(180 - x)° = 2(90 - x)° + 30°
To find the measure of the angle, solve the equation:
⇒ (180 - x)° = (180 - 2x)° + 30°
⇒ 180° - x° = 180° - 2x° + 30°
⇒ 180° - x° = 210° - 2x°
⇒ 180° - x° + 2x° = 210° - 2x° + 2x°
⇒ 180° + x° = 210°
⇒ 180° + x° - 180° = 210° - 180°
⇒ x° = 30°
Therefore, the measure of the unknown angle is 30°.

A find the probability that a randomly selected cap had a strength greater than 11 inch pounds
Answers
The probability that a randomly selected cap had a strength greater than 11 inch-pounds is approximately 0.2033 or 20.33% (rounded to two decimal places).
We know that cap strength, C, follows a normal distribution with mean μ = 10 inch-pounds and standard deviation σ = 1.2 inch-pounds. Therefore, we can standardize the variable C using the z-score formula:
z = (x - μ) / σ
where x is the value of cap strength we are interested in. In this case, we want to find the probability that a randomly selected cap had a strength greater than 11 inch-pounds, so x = 11. Plugging in the values for μ and σ, we get:
z = (11 - 10) / 1.2 = 0.83
Next, we need to find the probability that a standard normal random variable Z is greater than 0.83. This can be looked up in a standard normal distribution table or calculated using software. Using a standard normal distribution table, we find that the probability of Z being greater than 0.83 is approximately 0.2033.

Answer:
The angles are 60° and 120°.
Step-by-step explanation:
"supplementary" means that the two angles add up to 180°.
One angle can be x.
The other angle can be x+60° bc its 60° more.
Write an equation.

x = 60.
Since x = 60, one angle is 60° and the other is 120° (that's 60° more) and they are supplementary.

Answers
The variance is 7.2.
We can use the binomial distribution formula to calculate the variance. The formula for the variance of a binomial distribution is
Variance = n × p × (1 - p)
where n is the number of trials, p is the probability of success on each trial, and (1 - p) is the probability of failure on each trial.
In this case, n = 30 (the number of homes on the route), p = 0.48 (the probability of a home having a dog), and (1 - p) = 0.52 (the probability of a home not having a dog).
The postal employee encountered 12 dogs, which means there were 18 homes without dogs. So, the actual probability of success in this case is
P(dogs) = 12/30 = 0.4
Using the formula above, we can calculate the variance
Variance = n × p × (1 - p)
= 30 × 0.4 × 0.6

Answer is in the photo attached. Hope this helped!
The number of orange skittles in the bag is 32.
What is the ratio?Ratio is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
We are given that;
The ratio of purple skittles to orange skittles= 5:2
Total skittles= 112
Now,
Let's call the number of purple skittles in the bag "5x" and the number of orange skittles in the bag "2x", where x is a common factor.
We know that the total number of skittles in the bag is 112. So we can write:
5x + 2x = 112
Simplifying, we get:
7x = 112
Dividing both sides by 7, we get:
x = 16
Now we can find the number of orange skittles by substituting x = 16 into our expression for the number of orange skittles:
2x = 2(16) = 32
Therefore, by the given ratio answer will be 32 orange skittles in the bag.

How to Solve the Problem?a. To determine if there is a value of x such that g(x) = 0 for -3 ≤ x ≤ 2, we can plug in each value of x in the interval into the equation and see if we get 0.
g(x) = 2x^3 - 5x^2 + 4x - 1
For x = -3, g(-3) = 2(-3)^3 - 5(-3)^2 + 4(-3) - 1 = -55, which is not 0.
For x = -2, g(-2) = 2(-2)^3 - 5(-2)^2 + 4(-2) - 1 = 0, so there is a value of x such that g(x) = 0 for -3 ≤ x ≤ 2.
b. To find the absolute minimum and maximum values of g on the interval -7 ≤ x ≤ 9, we can use the Extreme Value Theorem, which states that a continuous function on a closed interval will have both an absolute minimum and maximum value on that interval.
To find these values, we can take the derivative of g(x) and set it equal to 0 to find critical points, and then evaluate g(x) at those critical points as well as at the endpoints of the interval.
g(x) = 2x^3 - 5x^2 + 4x - 1
g'(x) = 6x^2 - 10x + 4 = 2(3x-2)(x-1)
Setting g'(x) = 0, we get critical points x = 2/3 and x = 1.
g(-7) = -765, g(2/3) = -23/27, g(1) = 0, and g(9) = 1720.
Therefore, the absolute minimum value of g on the interval -7 ≤ x ≤ 9 is -765, and the absolute maximum value of g on the interval is 1720.

if the coconut from the shorter tree takes time t to reach the ground, how long (in terms of t ) will it take the other coconut to reach the ground?
Answers
2t
Question:
If the coconut from the shorter tree takes time t to reach the ground, how long (in terms of t) will it take the other coconut to reach the ground?
Solution:
We know that the time taken by the coconut to reach the ground is given by the formula:
t = √(2h/g)
Where,
t = time taken to reach the ground
h = height of the tree
g = acceleration due to gravity
If the height of the coconut from the shorter tree is h, then the time taken by it to reach the ground is t.
Now, the coconut from the taller tree has a height of 2h. Therefore, its time taken to reach the ground can be calculated as follows:
t_1 = √(2(2h)/g)
t_1 = √(4h/g)
t_1 = 2√(h/g)
Therefore, the time taken by the coconut from the taller tree to reach the ground is 2 times the time taken by the coconut from the shorter tree to reach the ground.
Hence, the answer is, the time taken by the other coconut to reach the ground is 2t.

8. A $15,000 Honda depreciates at the rate of 12% per year.
a) Write an equation.
b) How much is the car worth in 5 years?
c) To the nearest year, when will the car be worth $1000?
Answers
According to the given information, the equation is [tex]V = 15,000(1-0.12)^t[/tex], the car is worth $7,156.67 in 5 years and will be worth $1000 in 24 years.
What is the depreciation rate?
Depreciation rate is a mathematical process in which a quantity decreases over time in a manner proportional to its current value. This means that the rate of decay is proportional to the amount of the substance remaining, and as the amount of the substance decreases, the rate of decline also decreases
a) V = P(1-r)^t, where V is the value of the car, P is the initial price ($15,000), r is the depreciation rate (0.12), and t is the time in years.
[tex]V = 15,000(1-0.12)^t[/tex]
b) To find the value of the car in 5 years, substitute t = 5 into the equation:
[tex]V = 15,000(1-0.12)^5[/tex]
V = 7,156.67
The car is worth approximately $7,156.67 in 5 years.
c) To find when the car will be worth $1000, we need to solve for t in the equation:
[tex]1000 = 15,000(1-0.12)^t[/tex]
[tex]0.067 = (1-0.12)^t[/tex]
Take the natural logarithm of both sides:
ln(0.067) = t ln(0.88)
t = ln(0.067) / ln(0.88)
t ≈ 23.7
Therefore, the car will be worth $1000 in approximately 24 years.

A’(10, 5) is the image of A after a translation along the vector 〈−6, 0〉. What are the coordinates of A?
Answers
To perform the opposite translation, we add the opposite of the translation vector to the image point A': the coordinates of point A are (16, 5).
what is a vector?
In mathematics, a vector is an object that represents a quantity having both magnitude (or length) and direction. Vectors can be represented geometrically as arrows, where the length of the arrow represents the magnitude of the vector and the direction of the arrow represents the direction of the vector.
To find the coordinates of point A, we need to perform the opposite translation of moving along the vector 〈−6, 0〉 from the image point A'(10, 5). This is because a translation is a rigid motion that preserves the distance between points, so the distance between A and A' is the same as the distance between their respective translations.
To perform the opposite translation, we add the opposite of the translation vector to the image point A':
A = A' - 〈-6, 0〉 = (10, 5) - (-6, 0) = (16, 5)
Therefore, the coordinates of point A are (16, 5).
