So I don’t understand what I have to do exactly. Help me out ?

You have to make a frequency table.

Step-by-step explanation:

The classes are

.320- .329

.330-.339

.340 - .349

.350 - .359

.360 - .369

Then, you have to find to find how many values would fall into the class of .340 - .349.

.320 ≤ x ≤.329

All x values that are less than (or equal to) .329 but greater than .320 fall into the class of

.320- .329.

Frequency is just how many numbers are in a class.

50.6

step-by-step explanation:

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
