This is found by the volume of a cone formula
Where b is the base and h is the height
Which of the functions have period pi?
1 answer:
ANSWER
A.) y = tan x
C.) y = cot x
EXPLANATION
The period refers to the interval over which the graph completes one cycle
The trigonometric functions
and
are reciprocals of each other.
They have the same period, which is π
Also y=cscx and y=secx are reciprocals of the sine and the cosine functions respectively.
They have periods of 2π

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
