Answer:
10
Step-by-step explanation:
5/6 =0.8333
12x0.8333 = 10
6^3 = 216. When using chance, take the number of outcomes(six for a die) and raise it to the power of the number of repetitions
Answer: The unit rate is 3 centerpieces per hour
Step-by-step explanation:
18centterpieces/6hrs =3
Answer:
We conclude that the plant should shut down.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 60
Sample mean,
= 61.498
Sample size, n = 100
Alpha, α = 0.05
Population standard deviation, σ = 6
a) First, we design the null and the alternate hypothesis such that the power plant will be shut down when the null hypothesis is rejected.
We use One-tailed(right) z test to perform this hypothesis.
b) Formula:
Putting all the values, we have
Now,
Since,
We reject the null hypothesis and accept the alternate hypothesis. Thus, the temperature of waste water discharged is greater than 60°F. We conclude that the power plant will shut down.
Calculating the p-value from the z-table:
P-value = 0.0063
Since,
P-value < Significance level
We reject the null hypothesis and accept the alternate hypothesis. Thus, the temperature of waste water discharged is greater than 60°F. We conclude that the power plant will shut down.
Answer:
x = 0
Step-by-step explanation:
8 + 6x = 4 * 2
If this is the equation then start with multiplying 4 by two and subtracting 8 from both sides
6x = 0
Divide 6 from both sides
x = 0
To test this, insert the value of x which is 0
8 + 6(0) = 4 * 2
Multiply 6 and 0
8 + 0 = 4 * 2
Multiply 4 and 2
8 + 0 = 8
Add
8 = 8
This equation is true as you can see so x is equal to 0.
Hope this helps.
