Answer:
6.) So 8 of 24 hours is 1/3. So the percent of his time used was <u><em>33.33333 . . %</em></u> (etc)
7.) The easiest way to figure out a percentage is dividing it. So if it was 30 hit out of 75 people, then divide 30 by 75. So <u><em>40%</em></u> of them got hit.
Hope that helps
The sample std. dev. will be (14 inches) / sqrt(49), or (14 inches) / 7, or 2 inches.
Find the z score for 93.8 inches:
93.8 inches - 91.0 inches 2.8 inches
z = ------------------------------------- = ----------------- = 1.4
2 inches 2 inches
Now find the area under the standard normal curve to the left of z = +1.4.
My calculator returns the following:
normalcdf(-100,1.4) = 0.919. This is the probability that the mean annual precipitation during those 49 years will be less than 93.8 inches.
Answer:
36
Step-by-step explanation:
First do -1 - 5, which is -6.
then square -6.
so 6 x 6 equals 36.
Volume of a cone = <span>πr^2(h/3)
r=6
h=27
v = </span><span>π(6^2)27/3
v = </span><span>π (36)(9)
v=</span><span>π324 in. cubed
or
v=1,017.36 in. cubed </span>
Answer:
If your payment didn’t go through, change your preferred payment method/add another payment method.
For example, if your preferred payment method is your bank account, we'll always try to use your bank account first for payments. If there's an issue with your bank account, you can change your preferred payment method to a different one, such as a debit or credit card. If you only have a card registered on your account, try adding and confirming a bank account.
