Step-by-step explanation:
We have given
,
and SP =30
We have to find the slope for regression on Y from X
The slope on Y from X is given by ![b_{yx}=\frac{SP}{SS_X}](https://tex.z-dn.net/?f=b_%7Byx%7D%3D%5Cfrac%7BSP%7D%7BSS_X%7D)
As we have given the value of SP =30 and value of ![SS_X=10](https://tex.z-dn.net/?f=SS_X%3D10)
So slope for regression will be
Answer:
6x
-24
x = -4
Step-by-step explanation:
There's not really much work that goes into this problem.
<em>First, you have to get the variable by itself. To do that you do the opposite of multiplication which is division. 6 divided by 6 = 0. Since you did that to one side you have to do it to the other. -24 divide by 6 = -4. So, x = -4.</em>

An outlier is an observation that lies outside the overall pattern of a distribution. Usually, the presence of an outlier indicates some sort of problem. This can be a case which does not fit the model under study, or an error in measurement.hope this helps<span>

Hello!
We need to get a number that is greater than or equal too 120. First of all, let's calculate the sales tax.
120(0.07)=8.4
120+8.4=128.4
This gives us the inequality below.
7.5w+44≥128.4
Now we solve like an equation.
7.5w≥84.4
84.4/7.5≈11.25
w≥11.25
As you can see, the only number greater than 11.25 is D) 12 weeks which is our answer.
I hope this helps!
