Answer: 0.0062
Step-by-step explanation:
Given : Mean : 
Standard deviation :
Sample size : 
Assume that age of people in the country is normally distributed.
The formula to calculate the z-score :-
For x = 32
The p-value = 
Hence, the the probability that the average age of our sample is at least =0.0062
Answer:
904
Step-by-step explanation:
the formula is 2x3.14x the radius squared
6.28x the radius squared
6.28 x 144
904
The derivative of a variable raised to exponent of n, x^n is equal to the product of n and x raised to exponent of n-1.
d(x^n) = (n)(x^n-1)
So, from the given
d(9x + 5) = (1)(9x^1-0) + 5(0)
= 9
The given value of x is irrelevant to this item because the derivative does not contain any variable x.
The Julia age will be 39 years old if In 2021,Julia is 14 years old. Michael is 2.50 times as old as Julia.
<h3>What is a linear equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let's suppose the age of the Julia is x years when Michael is 60
Julia's age = 14 years in 2021
Age of Michael = 2.50×14 = 35 years
Increase in age Michael of 60 – 35 = 25
x = 14+25 = 39 years
Thus, the Julia age will be 39 years old if In 2021,Julia is 14 years old. Michael is 2.50 times as old as Julia.
