A = pi r^2
531 = 3.14 ( r^2)
169.12 = r ^2
Take the square root
13 = r
Diameter = 2r
D = 2(13)
D = 26 mm
Answer:
8
Step-by-step explanation:
Given:
Total money Jervane can spend = $20.
Cost of a coffee = $3.
Cost of a donut = $2.
To find: Maximum number of donuts Jervane can buy.
Solution:
Let the number of donuts she can buy be
.
She wants to spend no more than $20 in total.
So,





As the number of donuts can only be a natural number.
Hence, the maximum number of donuts that Jervane can buy are 8.
Let p equal Pam's age, and , equal Marion's age. If Marion is 3 years MORE than 5 times Pam's age, that means that:
m = (5p) + 3

Combine like terms
10a-10a+3a = 3a
2b+2b + 4b
ab2-10ab+4ab-7ab2 = - 18ab
answer: 3a + 4b + 18ab
Answer:
The p-value is 0.0577.
Step-by-step explanation:
The alternate hypothesis is:

P-value of the test:
The p-value of the test is the probability of finding a sample proportion above the one found, which is 1 subtracted by the p-value of z.
We have that z = 1.574.
Looking at the z-table, z = 1.574 has a p-value of 0.9423
1 - 0.9423 = 0.0577
The p-value is 0.0577.
