Answer:

I think y=1x+2

Step-by-step explanation:

y=mx+c

m=(y2-y1)/(x2-1)

I just chose (0,2) and (-3,-1)

-1-2=-3

-3-0=-3

-3/-3=1

y=1x+c

c= y-intercept and (0,2) is the y-intercept so

y=1x+2

I think

A normal distribution has a mean of 15 and a standard deviation of 2. Find the value that corresponds to the 75th percentile.
kirill115 [55]

Answer:

The value that corresponds to the 75th percentile is 16.35.

Step-by-step explanation:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score 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. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

A normal distribution has a mean of 15 and a standard deviation of 2.

This means that \mu = 15, \sigma = 2

Find the value that corresponds to the 75th percentile.

This is X when Z has a pvalue of 0.75. So X when Z = 0.675

Z = \frac{X - \mu}{\sigma}

0.675 = \frac{X - 15}{2}

X - 15 = 2*0.675

X = 2*0.675 + 15

X = 16.35

The value that corresponds to the 75th percentile is 16.35.

Write the standard form of the line that passes through the given points. Include your work in your final answer. Type your answ
weeeeeb [17]

The equation of the line is 2x + 5y = 11 hat passes through the points (3,1) and (-2,3)

<h3>What is a straight line?</h3>

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

\rm m =\dfrac{y_2-y_1}{x_2-x_1}

We have two points:

(3,1) and (-2,3)

The equation of the line passing through the points (3,1) and (-2,3)

\rm (y - 3) = \dfrac{3-1}{-2-3}(x+2)

\rm (y - 3) = -\dfrac{2}{5}(x+2)

5y - 15 = -2x - 4

2x + 5y = 11

Thus, the equation of the line is 2x + 5y = 11 hat passes through the points (3,1) and (-2,3)

A^2=49 and b^2=64, which of the following cannot be a value of a+b
scZoUnD [109]
The values of A and B have to be 7 and 8, respectively. Unless you also deal with negatives, which also means you can have -7 and -8 as values. So, anything besides 7, 8, -7, and -8 cannot be values.
