You use pi in the equation to find the circumference and/or area of a circle.
The parent function, here is
f(x) = x² which is upward opening parabola.
In order to get a graph of f(x) = x²-1, shift the parent function, f(x) = x² by +1 unit downward. This is the transformation.
9% is equivalent to 9 / 100 = 0.09 as a decimal fraction.
So the tax on $3,000 = 3000 * 0.09 = $270
B
Answer: 0.022
Step-by-step explanation:
Let p be the population proportion of horses were fed mostly alfalfa.
We are given that :
, since alternative hypothesis (
) is right tailed , so the test is a right-tailed test.
Also, we have
Sample size= 62
Sample proportion= 
Test statistic for population proportion:-

Substitute all values ,

P-value for right tailed test :
P(z>2.01)=1-P(z<2.01) [∵P(Z>z=1-P(Z<z))]
=1-0.9777844 [By using z-value table]
=0.0222156≈0.022
Hence, the P-value for this test is <u>0.022</u> .
