Answer:
120 cm²
Step-by-step explanation:
Applying,
A = Ph................... Equation 1
Where A = Literal Area of the triangular prism, P = Perimeter of the base, h = height.
But,
P = a+b+c............... Equation 2
Where a, b, c represent the three sides of the triangular base
Therefore,
A = h(a+b+c)............... Equation 3
From the question,
Given: h = 8 cm, a = 4 cm, b = 5 cm, c = 6 cm
Substitute these values into equation 3
A = 8(4+5+6)
A = 8(15)
A = 120 cm²

Answer:
Since we don’t know which side is which length, I’m going to tell you the two possible answers. The first possible answer is 2 * 6 = 8 and the second possible answer is 6 * 6 = 36

Answer: fail to reject the seven-minute average waiting time claim.
Step-by-step explanation:
As per given ,
Objective for test : the average waiting time is seven minutes or more.
Then ,
Since alternative hypothesis is right-tailed thus the test is an right-tailed test.
In a right tailed test , the rejection area lies on the right side of the critical value.
It means that if the observed z-value is greater than the critical value then it will fall into the rejection region other wise not.
i.e. If the value of your test statistic is less than the critical value, the correct decision is we fail to reject null hypothesis.
i.e. fail to reject the seven-minute average waiting time claim.
The complete statement would become:
If the value of your test statistic is less than the critical value, the correct decision is to fail to reject the seven-minute average waiting time claim.
