Answer:
As p-value = 0.0.68 > 0.05 the null hypothesis could not be rejected
Step-by-step explanation:
The computation of the p-value is shown below:
Given that
Average life =
= 88.5
Standard deviation =
= 9
Sample = n = 80
Based on the above information
Null and alternative hypothesis is

Now for the level of significance
= 0.05 and the critical value for a right talied test is 
Now the test statistic is

= 1.491
Now it is observed that
Z = 1.49≤z_ c = 1.64
So by this the null hypothesis could not be rejected
So,
P -value = 1 - P(z<1.491)
P-value = 0.068
As p-value = 0.0.68 > 0.05 the null hypothesis could not be rejected
Answer:
24.2
Step-by-step explanation:
You are given the hypotenuse and angle, and you want to find the length of the adjacent side.
The mnemonic SOH CAH TOA reminds you that the relation between angle and sides is ...
Cos = Adjacent/Hypotenuse
cos(41°) = x/32
x = 32·cos(41°)
x ≈ 24.2
Answer:
the ? is 3
Step-by-step explanation: the whole area of the angle is ten so minus three so it is three!
The expression would be (x+10)3 or 3(x+10)
Answer:
No, because you forgot to switch the sign when dividing by a negative number. Its the 2nd one
