Answer: The temperature dropped 8 degrees.

Step-by-step explanation:

The initial temperature was T0, and each hour the temperature dropped by 2°, for 4 hours.

So we can write the temperature as a function of time in the next way:

T(t) = T0 - (2°/h)*t

where t is the number of hours since the temperature started to drop.

The temperature drop for four hours, so we have that the final temperature is:

T(4h) = T0 - (2*4)°= T0 - 8°

then we can calculate the difference between the final and initial temperature as:

T(4h) - T(0h) = T0 - 8° - T0 = -8°

This means that in Friday morning the temperature dropped by 8 degrees.

Shenise is a star player for her women's basketball team. She has injured her ankle, and it is doubtful that she will be able to
Sladkaya [172]

Answer:

<u>The correct answer is that it's expected the team will score 72 points.</u>

Step-by-step explanation:

1. This is the information given in the question:

When Shenise can play the team scores 91 points

Without Shenise the team just scores 60 points

Therefore, when Shenise is at her best, her 100%, she scores 31 points by herself. When she's not in conditions, she can't play.

2. For finding out how many points Shenise can score if she plays, we use this formula:

If Shenise is at her 100%, she scores 31 points, how many points can she score if she's at 40% chance of playing?

Points upcoming game = 31 * 40 / 100

Points upcoming game = 1,240 / 100

Points upcoming game = 12.40 = 12 (rounding to the nearest whole number)

3. If Shenise plays, she can score 12 points. Now, we can calculate how many points her team will score.

Points the team scores when Shenise doesn't play = 60

Points the team will score if Shenise plays = 60 + 12 = 72

<u>The team will probably score 72 points with a 40% chance that Shenise will play the upcoming game</u>

Find the midpoint of a segment with endpoints (-9, 3) and (5, 7). <br><br> I need help ASAP pleasee
vfiekz [6]

Answer:

( -2,5)

Step-by-step explanation:

To find the x coordinates of the midpoint, add the x coordinates of the endpoint and divide by 2

( -9+5)/2 = -4/2 = -2

To find the y coordinates of the midpoint, add the y coordinates of the endpoint and divide by 2

( 3+7)/2 = 10/2 = 5

The midpoint is ( -2,5)
