The z-scores of the scores are -1.34, -0.73, 0.48, 0.48 and 1.10

<h3>How to transform the scores?</h3>

The sample scores are given as:

2, 3, 5, 5, 6.

Calculate the mean and the standard deviation using a statistical calculator.

From the statistical calculator, we have:

\bar x = 4.2 --- mean

\sigma_x = 1.64 --- standard deviation

The z-score is then calculated using

z= \frac{x - \bar x}{\sigma}

Where:

x = 2, 3, 5, 5, 6.

So, we have:

z_1= \frac{2 - 4.2}{1.64} = -1.34

z_2= \frac{3 - 4.2}{1.64} = -0.73

z_3= \frac{5 - 4.2}{1.64} = 0.48

z_4= \frac{5 - 4.2}{1.64} = 0.48

z_5= \frac{6 - 4.2}{1.64} = 1.10

Hence, the z-scores of the scores are -1.34, -0.73, 0.48, 0.48 and 1.10

A line passes through the point (–7, 5) and has a slope of 1/2. Which is another point that the line passes through?
Andrej [43]
The answer to this question is (9,13). Here's how:
First thing you need to do is find the equation. You have a coordinate point and the slope. Remember a linear equation or formula is y=mx+b (m= slope and b= y-intercept)

So let's input the slope into the equation:
y=1/2x+b or y=0.5x+b
Notice how there is no b yet? That's because you need to find it. Good thing you have the coordinate points, so replace x and y with it. ( (x,y) = ( -7, 5) )

5=0.5(-7)+b
5= -3.5+b
+3.5 +3.5
b= 8.5
The equation is now y=0.5x+8.5 and with that equation you can now input it in a calculator to find which of the following coordinate points lies on. Or you can just input those points into the calculator. Which I did because I love to show my work. I have a picture of the work included and I really do hope I helped you. If not, message me. I'll be glad you to help you!

Walmart is having a huge 25 % off sale!!!
IRISSAK [1]

9514 1404 393

Answer:

  $400

Step-by-step explanation:

If the price after taking 25% off is $300, then $300 is 75% of the original price.

  $300 = 0.75p

  $300/0.75 = p = $400

The original price was $400.

_____

<em>Check</em>

0.25 × $400 = $100

$400 -100 = $300 . . . . the price after taking 25% off
