Calculate the peak hour volume for six-15 minute periods with the following volumes: 125, 130, 135, 140, 145, 155

The peak hour volume is 620

Step-by-step explanation:

Here, we want to calculate the peak hour volume

To calculate the peak hour volume, we need some information

Firstly we need to know that a period of 15 minutes refer to 1/4 of an hour

So, the given volume needs to be multiplied by 4 to get the peak hour value

Now back to the values given, we need the highest of them all

As regards the question, the highest of them all is 155

So the peak hour volume here would be 155 * 4 = 620

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

answer: correct
