What about it? 7x+5 equals what
Answer:
scale = ½
center = (2, -5)
Step-by-step explanation:
The distance between A and B is 8
The distance between A' and B is 4
therefore the dilation scale factor is 4/8 = ½
As B and B' have the same x value, the center must also have the same x value of 2
The y value for A is -1
The y value for A' is -3
IF the y value for the center is Y
½(Y - (-1)) = (Y -(-3))
½(Y + 1) = (Y + 3)
½Y + ½ = Y + 3
-2.5 = ½Y
Y = -5
Qualitative is something that describe like the different colors of something.
And Quantitative are numbers are quantity like the name says.
So I would say that distance is quantitative.
I hope this helps :D
Answer:
D. 24.7
Step-by-step explanation:
First off we need to find the Mean of the data set. We take sum of all the data in the set and divide it by the number of sample in the data set.
Now we find the variance using the formula:
σ²=Σ(x-Mean)²
n-1
σ²=
σ²=
σ²=611.07
Now that we have the variance, we can use the variance to solve for the standard deviation by getting the square root of the variance.
SD=
SD=24.72
