Step-by-step explanation:

Let x equal the decimal. Set up two equations such that the digits after the decimal point are identical.

100x = 226.6666...

10x = 22.6666...

Subtracting the two equations, we have:

Step-by-step explanation:

A function with a fifth-degree polynomial have 4 turning points.

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

A function is a fifth-degree polynomial.

Now,

Since, We know that;

The turning point of n degree polynomial = n - 1

Here, The highest power of the polynomial = 5

Thus, The turning point of 5 degree polynomial = 5 - 1

                                                                           = 4

Therefore, A function with a fifth-degree polynomial have 4 turning points.

Answer:

a = 17

Step-by-step explanation:

using the cosine ratio in the right triangle and the exact value

cos45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then

cos45° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{a}{17\sqrt{2} }[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )

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:

Step-by-step explanation:

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

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.

In 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]

In this problem:

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.

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%

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
