Jon, Leroy, and Simon are having a free-throw shooting contest. Each boy
Zolol [24]

Answer:

B

Step-by-step explanation:

If you arrange a statistics in order from least to greatest, the middle number is the median.

If there is even number of numbers in a list, let it be n numbers, then we take the average of n/2th and n/2 + 1 th terms.

Here, all of them have 6 numbers, so 6/2 = 3  and 4th, we take average of 3rd and 4th number to find the median.

Since they are arrange in order we check each:

Jon = average of 6 and 7, (6+7)/2 = 6.5

Leroy = average of 6 and 8,  (6+8)/2 = 7

Simon = average of 5 and 6, (5+6)/2 = 5.5

Leroy's median is the greatest (7).

The distance between ladder and bottom of the slide is 4.9 meters.

Step-by-step explanation:

Given,

Height of ladder = 1 m

Length of slide = 5 m

The ladder will serve as perpendicular and slide will serve as hypotenuse.

The distance from bottom of the slide to ladder will be base.

a = 1

c = 5

a^2+b^2=c^2\\(1)^2+b^2=(5)^2\\1+b^2=25\\b^2=25-1\\b^2=24

Taking square root on both sides

\sqrt{b^2}=\sqrt{24}\\b=4.89

Rounding to the nearest tenth

b = 4.9 meters

The distance between ladder and bottom of the slide is 4.9 meters.

Keywords: square root, base
