Find the mean of the following data set. 42, 45, 58, 63

Answers

Answer 1

Answer:

The mean of the given data will be equal to 52.

What is mean?

Mean is defined as the ratio of the sum of the given data to the number of the counts of the data.

Given that:-

42, 45, 58, 63

The mean will be calculated as:-

Mean = Sum of the data sets ÷ Number of the data sets

Mean = ( 42 + 45 + 58 + 63 ) ÷ 4

Mean = 208 ÷ 4

Mean = 52

Therefore the mean of the given data will be equal to 52.

Answer 2

Answer: To find the Mean you have to add all the numbers from the data set,
$42+45+58+63=208$
Next you divide the sum by the amount of numbers in the set,
$208/4=52$
Final Answer: 52

Answer:

B) 33

Step-by-step explanation:

Jan starts out using 3 toothpicks to create Figure 1. She adds 4 toothpicks to create Figure 2 and adds another 4 toothpicks to create Figure 3. The equation for this question can be written as such:

3 + 2x = ? toothpicks

We will replace x with 15 because Figure 16 - Figure 1 is 15.

3 + (2 x 15) = ? toothpicks

2 multiplied by 15 is 30

3 + 30 = ? toothpicks

3 plus 30 is 33

The answer is B) 33

Can someone explain the steps to simplify x^4/3 over x^5/6 and how to simplify 16 square root of x * x^3 * x^4 (AGAIN EXPLAIN IN SENTENCES???)

Answers

remember
(x^m)/(x^n)=x^(m-n)

(x^4/3)/(x^5/6)=
x^(4/3-5/6)=
x^(8/6-5/6)=
x^(3/6)=
x^(1/2)

second one
16 times the square root of x*x^3*x^4
first simpify parenthasees
remember
(x^m)(x^n)=x^(m+n)
(x^1)(x^3)(x^4)=x^(1+3+4)=x^8

√x^8 aka
√(x^4)^2
is x^4

16x^4 is ansre√
