30 ÷ 6 represents a quotient.
30 is the dividend. 6 is the divisor. The quotient is 5.

5.2v represents a product of two factors.
5.2 and v are both factors.
5.2 is the multiplicand and v is the multiplier.
We don't know what the exact p-value is, but we are told that it's as large as 0.005 which is smaller than alpha = 0.05
Since the p-value is smaller than alpha, this means we <u>reject the null hypothesis</u>.
The way you can remember this is "if the p-value is low, then the null must go". By "low", I mean "smaller than alpha".
Recall that the p-value is the probability of observing that specific test statistic, or larger. So the chances of chi-squared being 18.68 or larger is a probability between 0.0025 and 0.005; there's a very small chance of this happening. The p-value is based entirely on the assumption that the null is correct. But if the null is correct, then the chances of landing on this are very small. We have a contradiction that basically leads to us concluding the null must not be the case. It's not 100% guaranteed of course, but it's fairly strong evidence.
In short, the p-value being smaller than alpha = 0.05 means we reject the null.
In order to accept the null, the p-value must be 0.05 or larger.
Answer:
Step-by-step explanation:
Given
Initial Temperature = -5F
Change (by noon) = 12 degrees
Required
Determine the temperature at noon
The temperature by noon is calculated as thus;
Substitute values for Initial temperature and change
Hence, the temperature at noon is 7F
Answer:
it increases
Step-by-step explanation:
honestly... i just guessed but its right
Answer:
32
Step-by-step explanation:
5(4)-2(-6) = 20 plus 12 = 32
