When you simplify (X-8)(x+4)+(x-3)(x+9) your will get the answer i got.
I hope ive helped you :)
Answer:
B. One of the populations is normally distributed.
Step-by-step explanation:
To test a claim about two population standard deviation or variance, it is imperative that the data meets certain requirements which include :
Randomness : Data must not be biased as such it must be drawn as a random sample from a larger group.
The data must be independent. That is not related to one another, the outcome of one should not rely on the outcome or value of another.
Both groups must be drawn From a population which is normally distributed.
One group being normally distributed by stribuyed while the other isn't a requirement for hypothesis testing in this scenario.
Answer:
C) 1/7
Step-by-step explanation:
so idk what the formula is called but it looks like this:
y2-y1/x2-x1 and if you plug in the numbers then you'll get the answer
3 - 4/-1 - 6 = -1/-7 = 1/7
you can also switch the numbers your answer will always be the same
4 - 3/6 - (-1) = 1/7
so the answer is c
The answer would be 6 because by adding the whole numbers, 3+2, you would get 5 and since the fractions both have denominators of 4, you had both fractions, 1/4+3/4, which gives you 4/4 or 1 whole. 5+1=6 and that's your answer.
Hope I Helped!
