Answer:
D
Step-by-step explanation:
I dont think this needs explained
The mean, median, and mode are equal to 1. So among the choices, the first one is correct - mean = mode
Mean - an <em>average </em>of the given set of number; to find this, add the numbers and divide it by 11 (the number of given data)
= (-1 + -1 + 0 + 1 + 1 + 1 + 1 + 2 + 2 + 2 + 3) / 11
= 1
Median - the <em>middle or center</em> of the given set; to find this, arrange the numbers in numerical order, then get the center or middle number as the median
= <span>-1, -1, 0, 1, 1, 1, 1, 2, 2, 2, 3
= [</span><span>-1, -1, 0, 1, 1,] <u>1</u>, [1, 2, 2, 2, 3]
Mode - is the value that occurs most of the time in the given set; so obviously <em>number 1 occurred four times</em> so 1 is our mode

Answer:
b.
Step-by-step explanation:
Seats to minutes = 2 to 11:
2/11 = s/m.
When s = 16:
2/11 = 16/m
m = 11*16 / 2
= 176/2
= 88 minutes.
When s = 19:
2/11 = 19 / m
m = 11*19 / 2
m = 209/2
= 104.5 minutes.
<span>B.) It is a straight line joining the points (0, −2), (2, 1), and (−2, −5).
[ It is because x- & y-coordinates are valid in this situation ]
Hope this helps!</span>
