The box plot has been shown to us. We know that in a box plot from the Lower Quartile to the Median the data is 25% of the total amount of data. Likewise, from the Median to the Upper Quartile it is 25% again and from the Upper Quartile to the last data. It is again 25%.

Now, as per the box plot given to us, 6 hours is the Lower Quartile, therefore, more than 6 hours at the computer will have 25%+25%+25%=75% of the total people. The number of total people is 220. Therefore, the number of people who spend more than 6 hours at a computer will be:

75% of 220= $\frac{75}{100}\times 220=165$

Thus, Option A is the correct option.

Answer:

(2, 18) and (-3, -7)

Step-by-step explanation:

y = 5x + 8 Substitute the value for y into the second equation

-10x + 2y = 16

-10x + 2(5x + 8) = 16

-10x + 10x +16 = 16

16 = 16 True

These two equation are the same line. So pick one of the equation to check which ordered pairs are true solutions.

Using y = 5x + 8

(0, -6) -5 = 5(0) + 8 ; -6 = 8 No

(-1, 9) 9 = 5(-1) + 8; 9 = -5 + 8 ; 9 = 3 No

(2, 18) 18 = 5(2) + 8; 18 = 10 + 8 = 18; 18 = 18 Yes

( -3, -7) -7 = 5(-3) + 8; -7 = -15 + 8; -7 = -7 Yes
