Answer:
-16 and 16 so A and E
Step-by-step explanation:
The positive version of -16 is 16
Answer:
a: no the sample size is too small
b: Yes, the distribution is normal with a mean of 40 and standard deviation of 12
Step-by-step explanation:
a: If n < 30, we need to know that the sample is normally distributed or else we can't determine anything. When sample sized get very large, they usually resemble normally distributed data sets so we can still make conjectures even if the data isn't officially normally distributed
b: The question tells us that the sample is normally distributed, so even though n < 30, we can still make conjectures about the population
(x-1)^2 is the factored version, so vertex is at 0, which is 1, so, A
Poorly phrased question, but the general answer is 5k/(12k), where k <span>∈ Z (i.e. k is an integer).
So, 5/12 and 10/24.</span>
Answer:
You can look for these:
Step-by-step explanation:
The factors of the equation:
For example, if multiplication, the factors 2x2=4
if addition, the addends 2 + 2= 4
So just look for the numbers before the equal sign and any key words in the problem.
Hope this helps!
