Answer:
Step-by-step explanation:
Isolate the b from one side of the equation.
<u>First, subtract by 5 from both sides.</u>
<u>Solve.</u>
<u />
<u>Subtract.</u>
9-5=4
2b=4
<u>Divide by 2 from both sides.</u>
2b/2=4/2
<u>Solve.</u>
<u />
<u>Divide the numbers from left to right.</u>
4/2=2
Therefore, the correct answer is b=2.
I hope this helps, let me know if you have any questions.
Step-by-step explanation
The answers in bold is what was required from the question.
the null hypothesis using symbol:-
H₀ : μ = 11.80
the alternative hypothesis using symbol:-
H₁: μ ≠ 11.80
This is a one tailed test. Given what you know, you will evaluate this hypothesis using a t test statistic.
Alpha level = 0.05
Sample size = n
Degree of freedom = n-1 = 40-1 = 39
To use the t distribution we will have to find the critical value from the t table this value is 1.685
But the question does not have sample mean and sample standard deviation. So I was unable to solve for the standard error
I'm just going to assume you want the probability of getting a certain outcome for the cubes and a coin
1/6*1/6*1/2
1/36*1/2
1/72
