Which description most accurately summarizes the sample results

The upper left answer.

Step-by-step explanation:

Using the box diagrams and the given data, the ranges for both the radios can be calculated by subtracting the minimum from the maximum of each data set:

Secure hike Emergency Radio 4.0

Range = 33-21=12

Xtreme Crank Radio

Range = 42 -25

The range of the Xtreme Crank Radio is bigger than the other radio, which means that the data is more spread out, making it less consistent..

The data also shows a lot more entries for the Xtreme Crank Radio that are 30 and above, whereas the secure radio has only a few.

Therefore, the top left answer describes the data best.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
