Camille asked five of her friends how long they studied for the last math test and what grade they received. She found a linear

regression equation for the data to be y = 9.6x + 65.8, with x representing hours.
What does the 9.6 and the 65.8 mean in the context of this equation?
A) 9.6 = the lowest score you can get;
65.8 = the highest score you can get
B) 9.6 = the number of points you would increase each hour of studying;
65.8 = your score if you studied 0 hours
C) 9.6 = the number of points you would increase each hour of studying;
65.8 = the highest score you can get
D) 9.6 = the number of hours you studied;
65.8 = your score if you studied 0 hours

Answer:

B. 9.6 = the number of points you would increase each hour of studying;

65.8 = your score if you studied 0 hours

Step-by-step explanation:

A linear regression equation y = 9.6x + 65.8, with x representing hours.

When x = 0, then y = 65.8. This means

65.8 = your score if you studied 0 hours

When x = 1, then

y=9.6+65.8=75.4

is your score after studying one hour.

The score increased by 75.4-65.8=9.6, so

9.6 = the number of points you would increase each hour of studying.

What is the probability that the first marble is blue and the second marble is yellow?
Cloud [144]

Answer:

\frac{1}{14}

Step-by-step explanation:

<u><em>First time drawing:</em></u>

Total outcome is 8

Favorable outcome is 2

The probability that the first marble drawing in random is blue is

\frac{2}{8} = \frac{1}{4}

<u><em>Second time drawing (with no replacement): </em></u>

Total outcome is 7  (8 - 1 = 7)  

Favorable outcome is 2

The probability that the second marble drawing in random is yellow is

\frac{2}{7}

<em>The probability that the first marble is blue and the second marble is yellow is</em> \frac{1}{4} × \frac{2}{7} = \frac{2}{28} = \frac{1}{14}
