Answer:
n= 42
Step-by-step explanation:
divide 420 by 10n and you get 42
Answer:
B)
Step-by-step explanation:
Because the y intercept remains the same and does not change at a constant rate like all the others.
A),C),and D) are wrong because they have a pattern and show liner relationship
Answer:
Mean of these n = 23 observations is 16.21 .
Step-by-step explanation:
We are given with the one‑sample t statistic from a sample of n = 23 observations for the two‑sided test of H0 : μ = 15 versus Hα : μ > 15 has the value t = 2.24 . Also, the standard deviation from the sample is 2.4.
So, Null Hypothesis, : = 15
Alternate Hypothesis, : > 15
The test statistics that is used here is One sample t-test statistics;
T.S. = ~
where, = sample mean
= population mean = 15
s = sample standard deviation = 2.4
n = sample size = 23
So, test statistics = ~
2.24 =
1.21 = - 15
= 1.21 + 15 = 16.21
Therefore, mean of n = 23 observations is 16.21 .
Answer:
Step-by-step explanation:
In order to solve this problem, we need to start by finding the probability of picking an oatmeal raisin cookies. Probabilities are found by using the following formula:
In this case, our number of desired events is the number of oatmeal raisin cookies we have available: 8.
Our number of possible events is the total number of cookies in the bag, which is:
6+9+5+8=28
so the probability is:
which simplifies to:
Next, we need to find the probability of picking one oatmeal raisin cookie again. This time we only have 7 oatmeal raising cookies and 27 cookies left in the bag, so our probability will now be:
So, the probability of picking an oatmeal raisin cookie at first and picking one of the same kind again is found by multiplying both probabilities.
So the probability that Dana randomly selects an oatmeal raisin cookie from the bag, eats it, then randomly selects another oatmeal raisin cookie is:
