Answer:
15.75 or 63/4
Step-by-step explanation:
The standard deviation of the sample mean differences is 4.854
<h3>How to determine the standard deviation of the sample mean differences?</h3>
The table of values is given as:
<u>Sample Standard deviation</u>
Red box 3.868
Blue box 2.933
The standard deviation of the sample mean differences is calculated using:
This gives
Evaluate the expression
Also, the table of value do not give any information regarding the sample size.
This means that the sample size of the session regarding the number of people would purchase the red box and the blue box are unknown
Hence, the standard deviation of the sample mean differences is 4.854

We know that the sum of all angle measures in a trapezoid is 360* (* means degrees)
Therefore we can construct the equation
(X+28)+(x)+(4x-14)+(4x-14)= 360
Now add like terms
10x = 360
And divide by the coefficient of X (aka 10)
X= 36
A percentage is a way to describe a part of a whole. The missing percent on the bar model is equal to 12.5%.
<h3>What are Percentages?</h3>
A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
On the percent bar model, above the missing percentage, the fraction is given as 1/8.
Now, the given fraction 1/8 in the form of percentage can be written as,
1/8
= 1/8 × 100%
= 0.125 × 100%
= 12.5%
Hence, the missing percent on the bar model is equal to 12.5%.
