Answer:
0.0035289
Step-by-step explanation:
From the question;
mean annual salary = $63,500
n = sample size = 31
Standard deviation = $6,200
Firstly, we calculate the z-score of $60,500
Mathematically;
z-score = x-mean/SD/√n = (60500-63500)/6200/√(31) = -2.6941
So we want to find the probability that P(z < -2.6941)
We can get this from the standard normal table
P( z < -2.6941) = 0.0035289
Answer:
B.20

THANK YOU.
Given that the figures are similar polygons, the ratio of their ratios should be equal to the square of the ratio of their circumference. If we let x be the lateral area of the smaller cylinder then,
(x/210π) = (24π/60π)²
The value of x from the equation is,
x = 33.6π
Thus, the area of the smaller cylinder is equal to 33.6π mm².
v + 9 / 3 = 8
v + 9 = 24
v = 24 - 9
v = 15
If you have any questions on how I got to this solution, please ask. :)
Answer: 41
Explanation: Use the equation. If you put the x value, which is 5, into the equation, you can solve.
4(5)+21
4 x 5 is 20
20+21=41
hope this helps!!
