Step-by-step explanation:
If a variables varies jointly, we can just divide it by the other variables in relation to it.
For example, since p variables jointly as q and square of r, then
where k is a constant
First, let find k. Substitute p= 200
q= 2, and r=3.
Now, since we know our constant, let find p.
Q is 5, and r is 2.
Answer:
ok
Step-by-step explanation:
Answer:
no, it cannot
Step-by-step explanation:
a difference of square is: a² - b² = (a - b)(a + b)
looking at the expression (5z+3)(-5z-3), we see that it does not fit the criteria of the breakdown of a perfect square, as (-5z-3) has a negative <em>a</em> term (-5z)
if we FOILed (5z+3)(-5z-3) out, we would get:
-25z² - 30z - 9, which is not a difference of squares

Answer:
c. you reject a null hypothesis that is true
Step-by-step explanation:
We need to remember the following concepts
Error type I: Is an error associated to the probability of reject a null hypothesis when it is actually true
Error type II: Is an error associated of not rejecting a null hypothesis when the alternative hypothesis is the true
And the best answer for this case would be:
c. you reject a null hypothesis that is true
