Answer:
y= -6x+2
Step-by-step explanation:
y=mx+b
Slope is also known/substituted by the variable m. Therefore we can come to the conclusion that m=-6.
y=-6x+b
Y-intercepts are substituted with the variable b. Therefore we can substitute the 2 as b, meaning b=2.
Leaving you with the final answer of:
y= -6x+2
Answer:
The value of R2 is 1.000, Choice D. Kindly rate my answer.
Step-by-step explanation:
Obtain a scatter plot in Ms. Excel then fit a quadratic trend line to obtain the value of R2 associated with the quadratic regression. R2 is referred to as the coefficient of determination and among other things it is a measure of the predictive power of the fitted model.
Answer:
190 freshman will probably go to the party
Step-by-step explanation:
first we have to get the probability of a person going
for this we will see those who said they will go on those who asked them
38/50 = 0.76 = 76%
Now we are going to multiply the 0.76 by the 250 people, and we will obtain the probable number of freshman that come to the party
250*0.76 = 190
X = 4 y = - 3
Substitute x for 4 and y for - 3
<u>x² - 4y
</u> 2
<u>4² - 4 *(- 3</u><u>)
</u> 2
<u>16 - ( - 12 )</u>
2
<u>16 + 12</u>
2
<u>28</u> = 14
2
Solution: 14
Hi.
The first question is a direct variation — specifically y = 1.8x
In the second one (if my calculations are correct), it's not a direction variation.
Hope this helps :)
Calculations:
y = 1.8(3) = 5.4
y does not equal x, 2x, or -2x.
