Answer:

D. 25% decrease

Step-by-step explanation:

Since it's clear that they read less books to find how much it decreased we multiply 100 with 15 then divide it by 20

100 × 15 ÷ 20 = 75 this result shows a 25% decrease.

Dahasolnce [82]

Answer:

The probabilty of selecting a red or yellow marble is 7/12

Step-by-step explanation:

To know the probability we have to divide the number of favorable events by the number of possible events

F = Favorable events: red or yellow marble

P = Possible events:  red, yellow or blue

F = 4 + 3

F = 7

P = 5 + 4 +3

P = 12

7/12

The probabilty of selecting a red or yellow marble is 7/12

Answer:

Y = -0.3587+0.09118X

92 %

Step-by-step explanation:

Using technology to fit the data between the variables, test score and hours of sleep; we obtain the linear model :

Ŷ = -0.3587+0.09118X

Where, x = test score ; y = hours of sleep

To obtain the test score of a student who sleep foe 8 hours using the model :

Y = 8

Ŷ = -0.3587+0.09118X

8 = -0.3587+0.09118X

8 + 0.3587 =0.09118X

8.3587 = 0.09118X

X = 8.3587 / 0.09118

X = 91.672515

X = 92 ( approximately)
