First you would need to add up all of the data given, then divide the sum by 9 because there is 9 pieces of data. So it would be 229/9=25.4444444 repeating.

Hello There!

Mean: Average of numbers in a set of data.

STEP 1: Add up all the numbers in the set of data. In this case, we would add

23 + 23 + 24 + 24 + 25 + 26 + 28 + 28 + 28 = 229

STEP 2: Divide the sum by the number of digits you added. We would divide

229 "sum of the numbers" by 9 "number of digits" and will get a quotient of

25.4444

-The mean for the set of data is 25.4444-

In an EFE Matrix, how much more important is a weight of 0.20 than a weight of 0.15? A. 50% B. 33% C. 25% D. .05% E. 5.0%

sergij07 [2.7K]

Answer: B. 33%

Step-by-step explanation:

In Mathematics , a percentage is basically a process of dividing the numerator by the denominator , then multiply the answer by 100.

We use Mathematical Formula : $\dfrac{\text{Difference between the Weight of 0.20 and Weight of 0.15 }}{\text{Weight of 0.15}}\times100$

Since , Difference between the Weight of 0.20 and Weight of 0.15 = 0.20-0.15=0.05

Then, substitute the value in formula , we get

$=\dfrac{0.05}{0.15}\times100\\\\=\dfrac{5}{15}\times100\\\\ \dfrac{100}{3}\%\approx33\%$

Hence, the weight of 0.20 is 33% more important than a weight of 0.15.

What is the solution for 4 x-3+1=1

liraira [26]

Answer:

$4 x-3+1=1$

$4x - 3 = 0$

$(4x - 3) + 3 = 3$

$4x - 3 + 3 = 3$

$4x = 3$

$\frac{4x}{4} = \frac{3}{4}$

In the equation 0.75 - 5/8s = 44, how do your combine the like terms?

Mnenie [13.5K]

Answer:

and let's then do away with the denominators, by multiplying both sides by the LCD of all fractions, in this case, the LCD will be 8, and then we'll combine the like-terms, but anyway, let's proceed.
