Answer

C. 49, 17, 4, 18

Step by step explanation

Here mean of all the data set is 88

To find the most spread of data, we need to find the range.

range of set A = The highest value - the lowest value = 36-6 = 30

Range of set B = 30-15 = 15

Range of set C = 49-4 = 45

Range of set D = 30-14= 16

Here the highest range is in Set C.

Therefore, answer is C. 49, 17, 4, 18

What is the value of 4⋅(2^2+5)^2÷3−1?

Hi there!

<u>Here is the step by step explanation into solving this :</u>

4 × (2² + 5)² ÷ 3 - 1

Start by solving the inside of the parentheses

2² = 2 × 2 = 4

4 + 5 = 9

Distribute the "²" to the whole parentheses

9² = 9 × 9 = 81

4 × 81 ÷ 3 - 1

Do the multiplication, then the division and lastly the subtraction

4 × 81 = 324

324 ÷ 3 = 108

108 - 1 = 107

The answer is : 107

There you go! I really hope this helped, if there's anything just let me know! :)

Is 4(4a+20b) equivalent to 16a+24b

8090 [49]

No.

When you are distributing, you are multiplying to each monomial

4(4a) = 16a

4(20b) = 80b

16a + 80b is your actual answer

hope this helps
