Her statement is not reasonable because it is not true that 25% of female marathoners run 13 or more miles a week, it is true that 25% run less than 13 miles a week (out of the data). The rest of the data would be 75%, making the statement, "75% of female marathoners run 13 or more miles a week" true. The way she recorded the data does not interfere with the statement being  reasonable since it is unbiased.

How do I solve for x?
PilotLPTM [1.2K]
So it states that the area of the rectangle is 56 cm, so all of it.
Given: 56 cm of rectangle
Unknown: find x
Length: 2 + x or x + 2
Width: 2x-5
Area = l * w
(x+2)(2x-5) 
set x equal to 0
x+2=0   --> x=-2                2x-5=0 --> 2x=5 --> x = 5/2
so the answer we got was x=-2,5/2
we know that x cannot be negative because you can't measure with negative numbers, therefore, 5/2 is your answer

tekilochka [14]
Archy:  15 gallons ... $23.85
               1 gallon ...$ x = ?

x * 15 = 1 * 23.85    /15
x = 23.85 / 15
x = $1.59 per gallon

Joe:  16 gallons ... $24.48
           1 gallon ... $ y = ?

y * 16 = 1 * 24.48    /16
y = 24.48 / 16
y = $1.53 per gallon

Result: Joe paid less per gallon.

A school track is shown.
ella [17]

Answer:

2232.36m

Explanation:

since the perimeter of two semicircles adds up to that of one circle, the perimeter of the track would be the perimeter of the circle + the length of the rectangle.

we can find the perimeter of the circle using the formula of π × diameter, which would be:

π × diameter

= 3.14 × 74

= 232.36

now, we can add this to the given length of the rectangle:

232.36 + 1000 + 1000 = 2232.36

thus, the perimeter of the track is <u>2232.36m</u>.

i hope this helps! :D
