Answer:
The mean is 0.32 and the standard deviation is 0.0122.
Step-by-step explanation:
Given that the Tampa Times polled 1,457 adults in the city to determine whether they put on their shirt before they put on their pants.
Of the respondents, 48% said they put their shirt on first.
32% of all adults actually put their shirt on first
i.e. sample proportion is 48% while population proportion is 32%
Hence sampling distribution follows a distribution with mean = population proportion p
Hence here mean = 0.32
Std deviation of sampling distribution =
Hence option 3) The mean is 0.32 and the standard deviation is 0.0122.
is right
Oblique Cone
The volume of the oblique cone is 144.49 cubic inches , if an oblique cone has a radius of 4 units, a height of 8.5 units, and a slant length of 11.7 inches.
Step-by-step explanation:
An oblique cone has a radius of 4 units
A height of 8.5 units
A slant length of 11.7 inches
We have to use the slant height to calculate actual base
So in a right angle triangle when two sides are given the third side is calculated by
Root (sqr(11,7) - sqr(8.5)) = 8.03 units
⇒ 8.03 units
Formula to calculate the volume of oblique cone,......................(1)
V =
If r is the distance of the base of the height from the center of the circle [ this is because the base of the height is outside the oblique cone]
V =
Where r is the distance if the base of the height from the center of the circle [ this is because the base of the height is outside the oblique cone]
Here r = 8.03 - 4 = 4.03 units
Volume = × 3.14 × 4.03 × 4.03 × 8.5
Volume = 144.49 cubic inches
Hence, the volume of the oblique cone is 144.49 cubic inches , if an oblique cone has a radius of 4 units, a height of 8.5 units, and a slant length of 11.7 inches.
