Answer:
The ways are described below.
Step-by-step explanation:
Given a rectangular prism whose given measures are 5 inches by 6 inches. Let these are length and width. Now, he says that by changing one dimension, he can make a prism with a volume of 240 cubic inches. we have to gives the 3 ways Cole can do this.
As volume of rectangular prism is V=lwh
∴ the dimensions of rectangular prism are 5, 6 and 8 inches.
One way Cole can make a prism with volume of 240 cubic inches is to take height 8 inches while the other two length 5 inches and width 6 inches.
Second way Cole can make a prism with volume of 240 cubic inches is to take height 6 inches while the other two length 5 inches and width 8 inches.
Third way Cole can make a prism with volume of 240 cubic inches is to take height 5 inches while the other two length 8 inches and width 6 inches.
Above all the three ways gives three different prism with volume 240 cubic inches.
Answer:
Margin of error at 90% is 0.024
Margin of error at 99% is 0.037
Step-by-step explanation:
Sample size = 1076
A poll found that 64% of a random sample of 1076 adults said they believe in ghosts.
So, No. of adults said they believe ghosts =
So, x = 688
n = 1076
z at 90% confidence is 1.64
So, margin of error at 90% is 0.024
Find the margin of error needed to be 99% confident.
z at 99% confidence is 2.58
So, margin of error at 99% is 0.037
