Answer:
The domain of P is given by,
{n | n ∈ N, 2 ≤ n ≤ 12}
Step-by-step explanation:
A perfect die is perfectly cubic in shape with one of the integers 1,2,3,4, 5 or 6 in each of it's 6 faces and the digits on any two faces are different.
Now, two dice are rolled and P(n) models the probability of the event that the sum on the faces of the two dice is n.
Hence, the domain of P is given by,
{n | n ∈ N, 2 ≤ n ≤ 12}
Answer:
Answer is B.9;0;-3
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
x – 2y = 12
-2y = -x + 12
y = 1/2x - 6
Slope in above equation is 1/2. If you want the slope of a perpendicular line take the inverse opposite which makes it -2/1 or just simply -2.
Rewrite the equation with the perpendicular slope:
y = -2x - 6
Answer:
a) Right-tailed test
b) 0.006569
c) We reject
.
Step-by-step explanation:
We are given the following information in the question:

We are testing the claim that p > 0.7
Alpha, α = 0.05
a) We have to identify type of test.
Since we test for claim p > 0.7, it is a one-tailed(right) test.
b) The p-value can be calculated with the help of standard normal table.

C) Since the p-value is less than the significance level, we fail to accept the null hypothesis and reject the null hypothesis.
Thus, we reject
.
