"Basketball players are generally taller.
Basketball player heights vary slightly more.
Step-by-step explanation:
I hope this helps!
Basketball players are taller because the average (mean) of basketball players is greater than soccer players.
Basketball player heights vary more because the MAD is greater or more than the soccer players."

1. Is (2, 4) a solution of the equation y = x - 2?
Answer:
No.
Step-by-step explanation:
If you plug in the numbers for the X and Y value, you will not receive the correct answer.
y = x - 2
(2, 4)
4 = 2 - 2
So, NO (2, 4) is NOT a solution of the equation y = x - 2.
This would only work if you were using addition instead of subtraction.

The 3 angles when added together need to equal 170.
To find the 3rd angle subtract the 2 given angles from 180
180-30-70 = 80
Answer: B. 80
Answer:
B) 80
Step-by-step explanation:
All triangles add up to 180 degrees
So to solve angle 3 the equation would be
Angle 3 = 180 - Angle 1 - Angle 2
Angle 3 = 180 - 30 - 70
Angle 3 = 80

A large group of students took a test in physics and the final grades have a mean of 70 with a standard deviation of 10. If the graph of the scores has normal distribution, what percentile would a student be in if they earned an A on the test? (a is a score ≥ 90)
Answer:
The student's score closest to 91 percentile.
Step-by-step explanation:
Since the scores on the standardized test are approximately normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = test scores.
µ = mean score
σ = standard deviation
From the information given,
µ = 480
σ = 90
If a student has a score of 600, then x = 600
For x = 600,
z = (600 - 480)/90 = 1.33
Looking at the normal distribution table, the probability corresponding to the z score is 0.91
the student's score closest to 91 percentile.
The graph of the scores has normal distribution and percentile would a student be in if they earned an A on the test is 97.72%
What is Normal Distribution?An example of a continuous probability distribution is the normal distribution, in which the majority of data points cluster in the middle of the range while the remaining ones taper off symmetrically toward either extreme. The distribution's mean is another name for the centre of the range.
Normal distributions are symmetric, uni-modal, and asymptotic, and the mean, median, and mode are all equal
A data set (when graphed) must follow a bell-shaped symmetrical curve centered around the mean
Given data ,
To determine the percentile a student would be in if they earned an A (a score ≥ 90) on the physics test, we need to calculate the z-score corresponding to the score of 90 and then find the percentile associated with that z-score.
The z-score is a measure of how many standard deviations a particular value is away from the mean in a normal distribution
z = (x - μ) / σ
where x is the value, μ is the mean, and σ is the standard deviation
In this case, we have:
x = 90 (the score for an A)
μ = 70 (the mean)
σ = 10 (the standard deviation)
Plugging these values into the z-score formula
z = (90 - 70) / 10 = 20 / 10 = 2
The z-score of 2 indicates that the score of 90 is 2 standard deviations above the mean in a normal distribution
The percentile associated with a z-score of 2 is approximately 97.72%
Hence , if a student earned a score of 90 or above on the physics test, they would be in the 97.72th percentile

write the equation of a line in point slope form that passes through (6,5) and (-3,2)
Answer:
[tex]y-5 = \frac{1}{3}(x-6)[/tex]
Step-by-step explanation:
Point Slope Form:
[tex]y-y_{1} = m(x-x_{1} )[/tex]
where m = slope
First, you have to find the slope of the line which is the difference in y values divided by the difference in x values.
[tex]m = \frac{y_2 - y_1 }{x_2 - x_1}[/tex]
[tex]m = \frac{2-5}{-3-6}[/tex]
[tex]m = \frac{-3}{-9} \\m = \frac{1}{3}[/tex]
Then plug in the values from either point to complete your equation of the line:
[tex]y-5 = \frac{1}{3}(x-6)[/tex]

The population of NBA players is Normally distributed
with a mean of 6'7" and a standard deviation of 3. 9
inches. (Wikipedia) Greg is considered unusually tall for
his high school at 6' 3".
1. About what percent of NBA players are taller than Greg?
2. About what percent are shorter?
3. What minimum height would Greg have to be (IN INCHES) in order to be in the top 2. 5% of
NBA player heights?
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.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
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 [tex]\mu = 6 \times 12 + 7 = 79[/tex].The standard deviation is of [tex]\sigma = 3.9[/tex].Greg is 6'3'', that is, X = 6 x 12 + 3 = 75.Item 1:
The proportion is one subtracted by the p-value of Z, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{75 - 79}{3.9}[/tex]
[tex]Z = -1.03[/tex]
[tex]Z = -1.03[/tex] 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.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.96 = \frac{X - 75}{3.9}[/tex]
[tex]X - 75 = 1.96(3.9)[/tex]
[tex]X = 83[/tex]
83 = 6 x 12 + 11.
A height of 6'11'' would be needed.
