The graph below displays a fire department’s response time, which measures the time from when the alarm is sounded at the firehouse to the time the first fire engine leaves the station. A histogram titled Fire Department Response Times has response time (seconds) on the x-axis and relative frequency on the y-axis. 20 to 30, 0.07; 30 to 40, 0.08; 40 to 50, 0.2; 50 to 60, 0.32; 60 to 70, 0.18; 70 to 80, 0.13; 80 to 90, 0.04.

Which interval accounts for the lowest percentage of response times?

20–30 seconds
30–40 seconds
70–80 seconds
80–90 seconds

I think its (D), 80-90 seconds. Someone check me.

I also think this is D.

Step-by-step explanation:

This question isn't asking for a lot of math so.

According to the graph, the 80-90 seconds response times are the shortest, meaning it is the least frequent or common.

Plus, it would be a bad thing if it was average anyways, and is outlined by the histogram.

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
