Answer:
x = 7.5
Step-by-step explanation:
Given that BE is parallel to CD and intersects the 2 other sides, then it divides the 2 sides in proportion, that is
= 
, substitute values
= 
( cross- multiply )
8x = 60 ( divide both sides by 8 )
x = 7.5
Answer: 40
Step-by-step explanation:
The angles form a straight angle, so y = 180 - 80 - 60 = 40.
Using the normal distribution, it is found that there was a 0.9579 = 95.79% probability of a month having a PCE between $575 and $790.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean 
and standard deviation 
is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:
.
The probability of a month having a PCE between $575 and $790 is the <u>p-value of Z when X = 790 subtracted by the p-value of Z when X = 575</u>, hence:
X = 790:
Z = 1.8
Z = 1.8 has a p-value of 0.9641.
X = 575:
Z = -2.5
Z = -2.5 has a p-value of 0.0062.
0.9641 - 0.0062 = 0.9579.
0.9579 = 95.79% probability of a month having a PCE between $575 and $790.

Yes they do.
16/12 and 4/3 forms of proportion
:^)
A.) if 4oz is drank every 4 hours, and there are 24 hours in a day, then there are 6 times during each day that the baby drinks formula. Knowing this, multiply 6 and 4 to get 24oz of formula each day
b.) if 1 can = 91fl oz, and, let's say 30 days in a month, then 24 multiplied by 30 will gives us how much is drank each month which is equal to 720fl oz. Divide 720 by 91 to get approximately 8 cans for one month.
c.) Go back to sub-problem a to find that the new amount per day is now equal to 16oz (6oz/4hrs ... 24/6 = 4 ... 4*4 = 16). Now take 30 and multiply it by 16 to get 480fl oz. Divide 480 by 91 to get approximately 5 cans for one month.
