Step-by-step explanation:
Given,
Length of railroad car = 6 inches
The length of railroad track = 5 feet
We will convert this length into inches.
1 feet = 12 inches
5 feet = 12*5 = 60 inches
Let,
x be the number of cars.
Number of cars * Length of each car = Length of track
Dividing both sides by 6
10 cars can fit on railroad track.
Answer: 1: x^2 + 25 = 0 x=5
2: x^2 - 11x + 28 = 0 x=7 i think
3: x^2 + 8x + 16 = 0 x=-4
Step-by-step explanation:
16, because all the other numbers are odd and 16 is even
12 and 14 are not functions cause they fail the horizontal line test!
Violent crimes include rap.e, robbery, assault, and homicide. The following is a summary of the violent-crime rate (violent crimes per 100,000 population) for all states of a country in a certain year.
Upper Q 1 equals = 272.8,
Upper Q 2 equals = 388.5,
Upper Q 3 equals = 529.1
The violent-crime rate in a certain state of the country in that year was 1,496.
Would this be an outlier?
The lower fence is ______ crimes per 100,000 population.
The upper fence is _______ crimes per 100,000 population.
(Round to two decimal places as needed.)
