I don’t understand what I’m suppose to do. Can someone please help?
Ksju [112]

From the 64 values in the table on the left, count how many fall within the given ranges under the "classes" column in the table on the right. The "frequency" is the number of values in the data that belong to a given "class".

For example, "< -16.0" means "values below -16.0". Only one number satisfies this: -16.2 (first row, third column). So the frequency for this class is just 1.

Then for the range "-15.9 - 13.0", which probably means "numbers between 15.9 and -13.0, inclusive", the frequency is 0 because every number in the table is larger than the ones in this range.

And so on.

9c + 6 = 24 what does the variable c equal
NARA [144]

Answer:

c = 2

Step-by-step explanation:

Isolate the variable, c. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& roots)

Multiplications

Divisions

Additions

Subtractions

~

First, subtract 6 from both sides of the equation:

9c + 6 (-6) = 24 (-6)

9c = 24 - 6

9c = 18

Next, divide 9 from both sides of the equation:

(9c)/9 = (18)/9

c = 18/9

c = 2

c = 2 is your answer.

~
