This is found by the volume of a cone formula

Where b is the base and h is the height

square root of 2.8 because its approximate form is 1.6733201 while square root of 2 is 1.4142136
Its B, C, E, F because for B the neg reciprocal of 1 is -1
Answer: a) 0.5636 b) 0.7881
Step-by-step explanation:
We assume that women’s heights are normally distributed .
Let x be the random variable that represents the shoe sizes.
Also, The population mean =
; Standard deviation: 
a) Formula for z:-

Put x= 64, we get

Now, the probability that the male shoe sizes are greater than 8 :-

Hence, the probability that her height is less than 64 inches = 0.5636
b. Sample size : n= 25
Then , the formula for z :-

Put x= 64, we get

Then, the probability that they have a mean height less than 64 inches.:_

Hence, the probability that they have a mean height less than 64 inches. =0.7881
Answer:
= 30 joules
Step-by-step explanation:
Work done is given by the product of Force and distance
Work done = Force × distance
Work is measured in joules.
Force = 20 N , distance = 1.5 m
Thus;
Work done = 20 N × 1.5 m
<u> = 30 Joules</u>
