An amusement park's owners are considering extending the weeks of the year that it is opened. The owners would like to survey 100 randomly selected families to see whether an extended season would be of interest to those that may visit the amusement park. What is the best way to randomly choose these 100 families
This is the Step-by-step explanation:
Allow a random number generator to come up with 100 families within a 50 radius of the amusement park.
A random number selector can be used to select 100 families out of the total number of families living within a 50 mile radius of the amusement park.
What is random sampling?Random sampling refers to the process of randomly selecting a set of samples from a population in random manner without bias.
The ransom sampling of the families in the survey can best be done by numbering all the families within a 50 mile radius of the amusement park.

Answer:
I think the answer is around 24 to 25 dollars.
Bella paid a total amount of $13.49.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
We have,
Bella ordered a $6 smoothie.
Sales tax = 9%
So, amount after tax

and, tip= 15%
Amount after tip
= 6 + 0.15 x 6
= $6.9
Thus, Bella paid

Area = 1/2 × NMP angle in radian × radius^2
Area = 1/2 × ( 40pi /180 ) × 12^2
Area = 1/2 × ( 2pi / 9 ) × 144
Area = 1/2 × 144 × ( 2 × 3.14 / 9 )
Area = 72 × 0.697
Area = 50.184
Area = 50.18 cm^2
Below is the normal distribution curve for height (inches) of NBA basketball players.
What is the standard deviation?
Answer: standard deviation = 8
This is because mu = 75 is the mean, which is at the very exact center of this distribution. One space to the right is 83, which is 83-75 = 8 units away from the center. This distance is exactly one standard deviation. We can say "83 is one standard deviation larger than 75".
Or you could note the distance from 67 to 75 is also 8, because 75-67 = 8. Each tickmark represents stepping one standard deviation in distance.

What is the length of the hypotenuse?
centimeters?
Answer:
Answer:
Length of leg of triangle =
Step-by-step explanation:
We are given a 45°-45°-90° triangle with hypotenuse measuring 18 cm.
Let us assume the following labeling of the diagram, as attached in the answer area.
The two angles here are equal to 45° so two sides of the triangle opposite to the equal angles will also be equal to each other i.e. it is an isosceles triangle.
i.e. The sides XY and YZ will be equal.
Let XY = YZ = x cm
It is known that in a right angled triangle, pythagorean theorem holds well.
As per pythagoream theorem:
Putting the values:
So, the length of leg of triangle =

a data set has a mean 25 and standard deviation 5 find the z score of 39
Answer:
[tex]\boxed {\boxed {\sf z=2.8}}[/tex]
Step-by-step explanation:
The z-score helps describe a value's relationship to the mean. It tells us how many standard deviations a value is from the mean. The formula is:
[tex]z= \frac{x- \bar x}{s}[/tex]
where x is the value, x-bar is the mean, and s is the standard deviation.
We know the data set has a mean of 25 and a standard deviation of 5. The value we are finding the z score for is 39.
x= 39 x-bar= 25 s=5Substitute the values into the formula.
[tex]z= \frac{ 39-25}{5}[/tex]
Solve the numerator.
[tex]z= \frac{ 14}{5}[/tex]
[tex]z=2.8[/tex]
The z-score for 39 is 2.8. This means a value of 39 is 2.8 standard deviations greater than the mean.
