The mean of the distribution is 4.9.

The calculation is as follows:

Here we have to determine the frequency from the cumulative frequency.

The Starting number is similar.

Now

To determine the next number subtract the previous number from that number.

i.e first number = 0.15

Second number = 0.45 - 0.15 = 0.3

Third number = 0.60 - 0.45 = 0.15

Fourth number = 0.85 - 0.60 = 0.25

Fifth number = 1.00 - 0.85 = 0.15

Now

Value Frequency Value × Frequency

1 0.15 0.15

3 0.3 0.9

5 0.15 0.75

7 0.25 1.75

9 0.15 1.35

Number of frequency = 1

Now

Total value should be

= 0.15 + 0.9 + 0.75 + 1.75 + 1.35

= 4.9

So, the mean is 4.9

4.9

Step-by-step explanation:

Let us first find the frequency from the cumulative frequency.

Starting number is same.

To find the next number subtract the previous number from that number.

i.e first number = 0.15

Second number = 0.45 – 0.15 = 0.3

Third number = 0.60 – 0.45 = 0.15

Fourth number = 0.85 – 0.60 = 0.25

Fifth number = 1.00 – 0.85 = 0.15

Value Frequency Value × Frequency

1 0.15 0.15

3 0.3 0.9

5 0.15 0.75

7 0.25 1.75

9 0.15 1.35

Number of frequency = 1

Total value = 0.15 + 0.9 + 0.75 + 1.75 + 1.35 = 4.9

Mean = $\frac{\text { Total value }}{\text { Number of frequency }}=\frac{4.9}{1}$ = 4.9

Answer from: Quest

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b

What is -2 (3x + 12y - 5 -17 -x -16y + 4 ) simplified?
