A.) 23 degrees Celsius

b.) y=23-5x

btw I'd rearrange this as

y= -5x+23

If you want to find changes in y, let's compare differences when we change the x.

For example, if x=1

y= -5(1)+23

-5+23=18

So, when x=1, y=18

Now, let's have x=2

y= -5(2)+23

-10+23=13

So, when x=2, y=13

Let's compare the difference in y by subtraction.

18-13=5

So, with every kilometer that you fly up from the surface, the temperature decreases by 5°C

So, in the box, put -5

Answer:

i)  = 23 °C

ii) = 4.4° C

Step-by-step explanation:

i) The temperature on the surface of the planet.

At the surface of the planet the height is Zero

Therefore, X = 0

Thus; using the equation, the temperature, y will be;

y = 23 - 5x

y = 23 - 5(0)

 <u> = 23 °C</u>

ii) the temperature change for every kilometer from the surface,

From the equation;

y = 23 - 5x

we take, y to be 1

Therefore;

1 = 23 -5x , subtracting 23 on both sides we get

-22 = -5x

x = -22/-5

<u>  = 4.4° C</u>

On a standardized exam, the scores are normally distributed with a mean of 300 and a standard deviation of 50. Find the z-score
Radda [10]

Answer:

z = -3

Step-by-step explanation:

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

z=\frac{x-\mu}{\sigma}\\\\z=\frac{150-300}{50}\\ \\z=\frac{-150}{50}\\ \\z=-3

This tells us that the person's score of 150 puts him/her 3 standard deviations below the mean of 300.
