Answer:

X= - 1/6

Step-by-step explanation:

Well its 16/7 = -8x

We can do a proportion over here

so 16/7 = -8x/1

Now just cross multiply to solve proportion

-56x=16

divide -56 to isolate x

x= 16/-56

Now simplify 16/-56

which is -1/6

So negative 1/6

Find the mean, median, mode, and range for each of the following sets of numbers
Sidana [21]

Answer:

The mean - 45\dfrac{2}{7}; the median - 35, the mode - 27, the range - 47.

Step-by-step explanation:

Arrange the set of data (31,74,27,58,65,27,35) in ascending order:

27, 27, 31, 35, 58, 65, 74.

The mean is the usual average, so add aal numbers and then divide by the number of numbers:

\dfrac{27+27+31+35+58+65+74}{7}=\dfrac{317}{7}=45\dfrac{2}{7}.

The median is the middle value. The middle value in the row 27, 27, 31, 35, 58, 65, 74 is 35.

The mode is the number that is repeated more often than any other, so 27 is the mode.

The largest value in the set is 74, and the smallest is 27, so the range is 74 – 27 = 47.
