Answer: 0.49 ± 0.0237
Step-by-step explanation: A interval of a 99% confidence interval for the population proportion can be found by:
± z.
is the proportion:
=
= 0.49
For a 99% confidence interval, z = 2.576:
0.49 ± 2.576.
0.49 ± 2.576.
0.49 ± 2.576.(0.0092)
0.49 ± 0.0237
For a <u>99% confidence interval</u>, the proportion will be between 0.4663 and 0.5137 or 0.49 ± 0.0237
Answer: The volume of pyramid is 6720 ft³
Step-by-step explanation:
Given: Base edge of a square pyramid = 24 feet
Slant height = 37 feet
Therefore height of pyramid is given by
where h is height, l is slant height and b is base edge of pyramid
So we have
Height of pyramid is 35 feet
Now the volume of a pyramid is given by
where V is volume , b is base edge and h is height of pyramid
Therefore
Hence , the volume of pyramid is 6720 ft³
