Samantha's percent error is 15.24%.
What is Percent Error?
The percent error is the distinction between the estimated value and the actual value in relation to the actual value. In other words, the relative error is multiplied by 100 to calculate the percent error.
Given:
Samantha guessed there were 295 jelly beans.
There were actually 250 jelly beans in the jar.
So, the percent error
= (295- 250) / 295 x 100
= 45 / 295 x 100
= 0.15254 x 100
= 15.24 %

Answer:
a) Area
b) 3,848 in. cubed
Step-by-step explanation:
Since we need to find the area of a circle, we have to insert the value of the radius (diameter ÷ 2) into the equation:
\(A = \pi r^{2}\\A = \pi (70/2)^{2} \\A = 35^{2} \pi \\A = 3,848.451\\A = 3,848\)

The two plots below show the heights of some sixth graders and some seventh graders:
Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders. Below the line for each dot plot is written Height followed by inches in parentheses. There are markings from 52 to 57 on the top line and the bottom line at intervals of one. For the top line there are 2 dots above the first mark, 1 dot above the second mark, 1 dot above the third mark and 2 dots above the fourth mark. For the bottom line, there is 1 dot above the third mark, 1 dot above the fourth mark, 3 dots above the fifth mark and 1 dot above the sixth mark.
The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 0.8. Approximately how many times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders? (Round all values to the tenths place.)

A rectangular flag is 60 centimeters by 96 centimeters. What are the dimensions of a scale drawing of the flag using the scale 1:6?
Answer:The dimensions of the scale drawing of the flag are 10 cm by 16 cm.
Step-by-step explanation:
The dimensions of a scale drawing of the flag are 10 centimeters and 16 centimeters.
What is a scale factor?The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).
Given:
The scale factor is 1/6.
A rectangular flag is 60 centimeters by 96 centimeters.
To find the dimension of new flag:
60 x 1/6 = 10 centimeters
96 x 1`/6 = 16 centimeters.
The dimensions of a scale drawing of the flag are 10 centimeters and 16 centimeters.
Therefore, flag's dimension are 10 centimeters and 16 centimeters.

This figure is the pre-image of a prism that has undergone a dilation with a scale factor of 3/4.
What is the surface area of the image after the dilation?
Answer:
194.625 m
Step-by-step explanation:
First, you would have to find the sides of the dilated prism.
12 * 3/4 = 9
13 * 3/4 = 9.75
5 * 3/4 = 3.75
11 * 3/4 = 8.25
Then, you would need to calculate to find the surface area.
2(9.75 * 8.25) = 160.875
9 * 3.75 = 33.75
Finally, add both the surface area of the rectangles are triangles together.
33.75 + 160.875 = 194.625
