The slope is 3.
In y=mx+b, the number before x (or m) is the slope.
10=2x5
60=2x2x3x5
2x2x5x3=60
i think to do this you need lcm but im not sure
Answer:
It is an example of proof.
Step-by-step explanation:
When using GeoGebra, I'm getting the regression curve to be roughly
h(t) = 1.67*(1.4)^t
I'm not sure how your teacher got 1.64 instead of the 1.67, but it's fairly close. So it seems like choice B is the best answer for the first part.
---------------------------------------------------
Once we know the regression equation, we plug in t = 14 to find that,
h(t) = 1.64*(1.4)^t
h(14) = 1.64*(1.4)^(14)
h(14) = 182.236911939151
h(14) = 182.2
If 14 days have gone by, then we estimate the height is roughly 182.2 inches.
Compared to what the table says, which is 190 inches, we see that we have an underestimate. The error is about 190-182.2 = 7.8 which is under 10.
Answer: Choice C
The model <u>under-predicts</u> the actual height by <u>less than 10 inches</u>
Answer:
First option
Step-by-step explanation:
Formula of perimeter =
Length + Length + Breadth + Breadth
So,
4x + 8 + 4x + 8 = 8x + 16
8x + 16 + 2x - 3 + 2x - 3 = 12x + 10
