Can someone help me with this Im not sure if My answer is correct

Answer:

y = 2x - 3

Yes, your answer is correct.

Step-by-step explanation:

First, find the slope of the two points by using the slope formula:

        y2 - y1

m = -------------

        x2 - x1

         13 - 5

m = -------------

          8 - 4

         8

m = ------- = 2

         4

To find the y-intercept, plug in values into the slope-intercept formula:

y = mx + b

Where m = slope and b= y-intercept. Use any one of the points. I'll be using (4,5):

5 = (2) (4) + b

5 = 8 + b

-3 = b

b = -3

So, putting everything into the slope intercept formula:

y = 2x - 3

Why is the absolute value of every number positive
bekas [8.4K]

Step-by-step explanation:

it's like walking if the point is 3 foot in front of you and you walk to it once you get to it then even if you keep walking you can't go a negative number of feet away from it because the closest you can get is right on it.

Many states assess skills of their students in various grades. One program that is available for this purpose is the NAEP. One o
Hoochie [10]

Solution :

Given :

National mean score of the reading test that is conducted the NAEP = 288

Standard deviation of the score = 38

Therefore, P(X > x) = 0.25

P (Z > $\frac{x-288}{38} $ = 0.674)

$\frac{x-288}{38} = 0.674$

$x=288+(38 \times 0.674)$

x = 326.67

Therefore, the highest score that is needed for the students to be in the top of 25 percent among the students those who take the exam.
