At 9:00 a. m., the wind speed at Harbor Bay was recorded. After that, the wind speed was recorded every hour. Each measurement showed an increase in wind speed of 3 miles per hour. The strongest wind was recorded at 4:00 p. m., and measured 52 miles per hour. After that, the wind speeds started to decrease. How windy was it when the experiment began?

The wind speed was 31 miles per hour when the experiment began.

Step-by-step explanation:

Linear Dependency

The wind speed is known to increase at a rate of 3 miles per hour every hour.

From 9:00 a.m. to 4:00 p.m. there are 7 hours.

Thus, the speed increased by 7 * 3 = 21 miles per hour during that period of time.

Assuming the wind increased linearly, and its speed was measured at 52 miles per hour at 4:00 p.m., then the initial speed at 9:00 a.m. is calculated by subtracting:

52 miles / hour - 21 miles / hour = 31 miles / hour

The wind speed was 31 miles per hour when the experiment began.

step-by-step explanation:

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
