Suppose he uses x mls of solution B.
0.5*1200 +0.1x=0.4(1200+x)
600+0.1x=480+0.4x
0.3x=120
x=400
Using the normal distribution, it is found that:
1. 85% of NBA players are taller than Greg.
2. 15% are shorter.
3. A height of 6'11'' would be needed.
<h3>Normal Probability Distribution</h3>
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:
- In inches, considering that a feet has 12 inches, the mean is of .
- The standard deviation is of .
- Greg is 6'3'', that is, X = 6 x 12 + 3 = 75.
Item 1:
The proportion is <u>one subtracted by the p-value of Z</u>, hence:
has a p-value of 0.15
1 - 0.15 = 0.85.
85% of NBA players are taller than Greg.
Item 2:
100 - 85 = 15% are shorter.
Item 3:
This is X when Z has a p-value of 1 - 0.025 = 0.975, so X when Z = 1.96.
83 = 6 x 12 + 11.
A height of 6'11'' would be needed.

Check the picture below
so, the volume will then be, the product of the area of the triangle and the height of the prism, and as you know, the area of the triangle is 1/2bh
The length of the line is B
Answer:
4 7/10
Step-by-step explanation:
2 3/5 = 2 6/10
1/2 = 5/10
2 6/10 - 5/10 = 2 1/10
2 6/10 + 2 1/10 = 4 7/10
hope this helped :)
