Answer:
143400
Step-by-step explanation:
I don't really understand what you are talking about, but i think you are trying to figure out this word problem so:
times is always multiplication.
So just multiply 478 with 300
Which is 143400
Hope this helps!
Using the normal distribution, it is found that the third quartile is of Q3 = 0.67, hence option B is correct.
In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
- After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
In this problem:
- The mean is of 0ºC, hence .
- The standard deviation is of 1ºC, hence .
The third quartile is X when Z has a p-value of 0.75, as , hence <u>X when Z = 0.67.</u>

Answer:
The answer is b and r=5x+7 is 35x
Step-by-step explanation:
From diameter you get radius by halving the diamter
radius = 14/2 = 7 cm
volume, height, and radius of a cylinder are all related by formula for volume of cylinder:
V = <span>πr²h
If we want to solve for h, we divide both sides by </span><span>πr² and get
h = V/(</span><span>πr²)
since V = 112</span><span>π and r = 7, h is equal to
h = (112</span>π)/(<span>π*7²) = 112/49 = 16/7 cm
height is C 16/7 cm
</span>

do I solve it or what am I supposed to do
