Yes..........................
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.
The answer is x = 6
To solve this you would use the pythagorean theorem which is a^2 + b^2 = c^2
In this problem a = x b = 8 and c = 10
You would then square these numbers
x^2 + 64 = 100
Next, you would subtract 64 from both sides.
x^2 = 36
All that’s left is the find the square root, which is x = 6.
So, therefore, you’re answer is x = 6
Answer: I believe the area of this shape is 40
Step-by-step explanation:The formula for the surface area of a prism is obtained by taking the sum of (twice the base area) and (the lateral surface area of the prism). The surface area of a prism is given as S = (2 × Base Area) + (Base perimeter × height) where "S" is the surface area of the prism.
