Answer:
Step-by-step explanation:
A rectangular prism has 12 edges. In geometry, a prism is a solid figure with parallel ends or bases that are the same size and shape, with each side representing a parallelogram. The parallelograms in a rectangular prism are all rectangles.
The rectangular prism also has six faces, or flat sides. The surface area of a rectangular prism is determined by multiplying the length by the width of each of the six rectangles and by then adding the products together.
Answer:
Step-by-step explanation:
a) Perimeter of a rectangle = 2 *(L +w)
b) w = L - 2
Answer: B
c) Perimeter = 96 inches
2* (l +w) = 96
2*( L + L - 2 ) = 96 {Combine like terms}
2 * (2L - 2) = 96 {use distributive law}
2*2L - 2*2 = 96
4L - 4 = 96 {Add 4 to both sides}
4L = 96 +4
4L = 100 {divide both sides by 4}
4L/4 = 100/4
L = 25 inches
d) w = L - 2
= 25 - 2
w = 23 inches

Answer:
Std deviation would change but IQR would not change.
Step-by-step explanation:
Given that after entering the test scores from her Statistics class of 25 students, the instructor calculated some statistics of the scores. Upon checking, she discovered that she had entered the top score as 46, but it should have been 56.
When arranged in ascending order the last entry would be 56 instead of 46.
Hence this would not affect the middle entry or quartiles
i.e. in other words there would not be any change in the Interquartile range and Quartile 1 and Quartile 3 are not changed
But standard error would change. this is because total of all entries now increase by 10, so average would increase by 10/25 = 0.40
This in turn would change the mean deviation x-average for each entry and hence square of deviations. Thus variance would change and also standard deviation.
No, Yes, Yes, No, No. The ones for no are decimals. The ones for yes are whole numbers.
