Answer:

The answer is

<h2>17 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x_1 - x_2})^{2} +  ({y_1 - y_2})^{2}  } \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A (-6 -3) and b (-14 -18)

The distance between them is

|AB|  =  \sqrt{ ({ - 6 + 14})^{2}  +  ({ - 3 + 18})^{2} }  \\  =  \sqrt{ {8}^{2}  +  {15}^{2} }  \\  =  \sqrt{64 + 225}  \\  =  \sqrt{289}  \\  = 17 \:  \:  \:  \:  \:  \:

We have the final answer as

<h3>17 units</h3>

Hope this helps you

On a standardized exam, the scores are normally distributed with a mean of 145 and a standard deviation of 25. Find the z-score
Kryger [21]

Answer:

z = 2.6

Step-by-step explanation:

<u>Use the formula for z-score</u>

z=\frac{x-\mu}{\sigma}\\ \\z=\frac{210-145}{25}\\ \\z=\frac{65}{25}\\ \\z=2.6

This tells us that this person's score of 210 places them 2.6 standard deviations above the mean

Y = 2x + 4<br> 6x – 3y = -12<br> System by substitution 10 points
Burka [1]

Answer:

(-2, 0)

Step-by-step explanation:

y = 2x+4

6x - 3y = -12

Start by simplifying the second equation by dividing everything by 3 (this will make the math easier)...

2x - y = -4

Then, substitute 2x+4 for y into the second equation (this is because y = 2x+4)...

2x-3(2x+4)=-4

Distribute the -3

2x-3(2x)-3(4)=-4

2x-6x-12=-4

Combine like terms

-4x-12=-4

Add 12 to both sides

-4x-12+12=-4+12

-4x=8

Divide both sides by -4

x=-2

Plug -2 back in for x to solve for y:

y = 2(-2) + 4

y=-4+4

y=0

(x, y) = (-2, 0)
