X/3=1351/7
cross multiply
7x=4053
divide by seven on both sides
x=579
Answer: No
Step-by-step explanation:Divide 4 from both sides to find that x actually equals 13.5
Answer:
sample variances
Step-by-step explanation:
The pooled variance method is used to estimate the variance of several different population with different means, but are assume to have the same variance.
The weights represent the sample variances.
So the correct answer is
sample variances
Take the f function minus the g function and subtract like terms
4 - (-2) is 6, so that part is 6*8 to the x power,
then you have the 18x with nothing subtracted from it,
and then -7 - -12....or at least that looks like -12...hard to see with it being covered up...anyway that part would be 5.
so 6*8^x + 18x + 5 is the answer
