Answer:

x should equal -2

Step-by-step explanation:

-4 (3x + 1) + x - 3 = 15

-12x - 4 + x - 3 = 15

-12x + x - 4 - 3 = 15

-11x - 7 = 15

-11x - 7 + 7 = 15 + 7

-11x = 22

-11 ÷ -11x = 22 ÷ -11

x = -2

Answer:

Step-by-step explanation:

we will use distributive property first

-12x-4+x-3=15

-11x-7=15

-11x=15+7

-11x=22

x=22/-11

x=-2

What is the data point that is the farthest from other data points when the box plot is NOT symmetrical?
Naddika [18.5K]

Answer: B. Outlier

Step-by-step explanation:

An outlier is an extremely large or extremely small data value in a data set such that it appears far from the other data points when we plot data points on scatter plot or box plot.

Thus, the data point that is the farthest from other data points when the box plot is NOT symmetrical is Outlier.

Its presence affects the value of mean directly. So when a data set have outliers , we prefer Median(Mid value of a data set) as the best measure of central tendency because existence of outliers does not effect Median .

Hence, the correct option is B. Outlier.

A private jet flies the same distance in 10 hours that a commercial jet flies in 8 hours. If the speed of the commercial jet was
Vladimir [108]
Commercial jet's speed = 2x-162 (plug this in the equation below)

Private jet's speed = x

Equation:

10(x) = 8(2x-162)
10x = 16x - 1296
6x = 1296
x = 216 (Private jet's speed)

Take the first equation and plug x value in;
2x-162
2(216) - 162 = 270 ( Commercial jet's speed)
