((-9+14)/2, (-20+12)/2)
(5/2,-8/2)
(5/2,-4)
The answer I think is Y= 2x-4
Start on the x axis then read the y axis , because the line goes through on the left it would be -
3x92 = 276 (first 3 exams)
average of at least 90 (90 x 4 = 360)
360 - 276 = 84

Answer:
.3
Step-by-step explanation:
The probability distribution in the second row simply shows the probabilities for each number in the first row.
To find the probability that x is between -5 and 5, you can add the probabilities -5 < x < 5.
P(-5) = 0.15
P(0) = 0.05
P(5) = 0.1
0.15 + 0.05 + 0.1 = 0.3
