Answer: 5 classes.

Step-by-step explanation:

You can use the  rule to determine the number of classes for a frequency distribution.

The  rule says that  where

is the number of classes

is the number of the data points

We know that the number of data points is  = 20.

Next, we start searching for  so that we can get a number 2 to the  that is larger that the number of data points.

This suggests that you should use 5 classes.

Answer:

  2

Step-by-step explanation:

The curve's highest value is -1.

The curve's lowest value is -5.

For a symmetrical wave like this*, the amplitude is half the difference between the highest and lowest values:

  1/2(-1 -(-5)) = 2

The amplitude is 2.

_____

* There is no general agreement as to how to compute the amplitude when the wave is asymmetrical. Some authors use the same formula. Some consider the amplitude to be the maximum deviation from average. Some define only a "peak-to-peak" amplitude in those cases. The meaning of "amplitude" in those cases depends on the context in which the question is asked.

ASAP: Hose A fills a water truck at the constant rate of 60 gallons every 15 minutes. Hose B fills a water truck at a constant r
jeka57 [31]

Answer:

C

Step-by-step explanation:

Hose A:

60 gallons every 15 minutes mean:

60 / 15 = 4 gallons per minute

For Hose B:

If we put x = 1, we can find gallons (y)  per minute (x)

y = 3 x

y = 3(1)

y = 3

That means 3 gallons per minute

Thus, the rate of Hose A is 1 gallon per minute more than the rate of Hose B. Option C is correct.
