Which statement about the system of equations is true?

1 answer:

3 0

8x + 6y = 10 ----------- (1)
5x - 3y = 2.2 ---------- (2)

(2) x 2:
10 x - 6y = 4.4 --------(2a)

(2a) + (1)
18x = 14.4
x = 1.8 ------- sub into (1)
8 (1.8) + 6y = 10
14.4 + 6y = 10
6y = 10 - 14.4
6y = - 4.4
y = - 0.73

There is 1 set of solution to it. (Answer C)

Answer:

(d)

Step-by-step explanation:

When the data is put in order, the values are ...

24, 28, 32, 34, 40, 44, 49

The middle value is 34. This is the median, where the line in the middle of the box plot is located. Only one answer choice has this correctly placed.

When the median is removed, the data set is divided into two parts:

24, 28, 38 and 40, 44, 49

The middle value of each of these will be the lower and upper quartiles, the ends of the box in the box plot. Those are 28 and 44.

So, the box plot has whiskers that extend to the extreme data points of 24 and 49, box ends at 28 and 44, and a median line at 34. The last choice matches this description.
