A positive correlation means the x and y axis are both increasing
so it starts on the bottom left and is moving towards the top right
Im gona assume you mean
f(x) = 3x + 2 + 8x + 4. Add like-terms
Y = 11x + 6
0= 11x + 6
-6 = 11x
X= -6/11
I’m pretty sure it’s the third one but I’m too good at math. I hope this helps you though and have a great day/night :)
Take
, so that
and
. Note that this assumes
and so requires
.
Now take
, so that
. Note that for this invertibility condition to hold, we require that
, which means
. But since we already fixed
with the previous substitution, we thus have
, which in turn restricts us to
. So with this substitution, we have
, which gives
Now over the interval
, we have
, which means
, and so the integral is equivalent to
Answer:
83 degress
Step-by-step explanation:
We know that every hour it dropped 8 degress. If it dropped from 4pm to 8pm, that means it dropped 4 times. 3x4=12 so we do 95-12 which equals 83.
