Answer:
Step-by-step explanation:
In the line plot, the red dots above each measurement on the number line indicates the frequency of that particular measurement.
From the information given,
Measurement Frequency
fifteen inches 4
Twenty five inches 7
Thirty five inches 3
Fourty five inches 5
Fifty five inches 1
Therefore, the most common pet length is Twenty five inches.
The least common pet length is Fifty five inches.
The difference between the least common and the most common pet lengths is 7 - 1 = 6
Slope = (6 - 3)/(-2-2)
= 3/-4
= -3/4
answer
slope = -3/4
Answer:
x = 3/2
Step-by-step explanation:
4X + 1/2(4X +6)=12
Distribute
4x+2x+3 = 12
6x +3 = 12
Subtract 3 from each side
6x+3-3 = 12 -3
6x = 9
Divide each side by 6
6x/6 = 9/6
x = 3/2
Answer:
A. 36 degrees
Step-by-step explanation:
180 is for straight lines,
180-79-68
= 36 degrees
The tail of the train starts one mile from the mouth of the tunnel and it must travel that distance plus the length of the tunnel in 3 minutes.
Let t = tunnel length
t + 1 = distance the tail must travel in 3 minutes.
3 minutes = 1/20 hr
(t+1) miles / 60 m/hr = 1/20 hr
t + 1 = 60/20
t+1 = 3
Subtract 1 from each side:
t = 2
The tunnel is 2 miles long.
