A)
<h3>
The sample mean is 52</h3><h3>
The claimed population mean is 44</h3>
---------
The sample mean is the mean found in the survey (of the sample of people). The sample mean is found by adding up the values and dividing by the sample size n. The larger n gets, the closer the sample mean should get to the population mean. This is assuming the sample is random and representative of the population.
The population mean is a claim made by another study/survey/etc. Usually generalized statements such as "Americans spent an average of X dollars (in year Y)" would have X be considered the population mean.

B)
<h3>Sample mean is 3.42</h3><h3>Claimed population mean is 3.56</h3>
--------
Same idea as part A, but we're using different numbers and a different problem context.
==================================
Note: The year numbers and the sample sizes are not used to answer any of the four questions above.
V (7,9) would make PRTV a square
Small feet are 4 inches and big people feet have a high lower inches for big feet but not sure
The inverse....switch ur x's and y's...
inverse :
domain is { -2,2,4,4,5} ...notice u have 2 "x" values that are 4
range is {-3,0,2,3,4}
The relation DOES NOT represent a function. A function will not have any repeating x values. It can have repeating y values, just not the x ones.
Now the relation would be a function...but the inverse is not
Answer: 15 cm²
Step-by-step explanation: To find the area of a triangle, start with the formula for the area of a triangle which is shown below.
In this triangle, the base is 6 centimeters and the height is 5 centimeters. Now, plugging into the formula, we have 
.
Now, it doesn't matter which order we multiply.
So we can begin by multiplying 1/2 times 6 cm and notice that the 2 in 1/2 and the 6 cross cancel to 1 and 3. So we're left with 3 cm.
Now, (3 cm)(5cm) is 15 cm².
So the area of the triangle is 15 cm².
