Step-by-step explanation:
I'm not good at math but I think is 3f because you'll be multiplying f(unknown #) by 3 so f(x) would be 3f

Complete question is;
Alejandro and Noya were told to draw a net for an octagonal prism. Which statement about the students’ nets is true? Both nets do not form octagonal prisms.
A) Only Alejandro’s net is correct.
B) Only Noya’s net is correct.
C) Neither net is correct.
D) Both nets are correct.
Answer:
C) Neither net is correct.
Step-by-step explanation:
From the second attached image, we can see what an octagonal prism looks like when it is opened to show all the faces.
However, looking at the first attached image showing the net drawings of boya and Alejandro, it is very clear that none of them got the required shape for the octagonal prism. Therefore, we can conclude that neither of the nets are correct.
The sample mean value is 0.26.
According to the statement we have given that the
Monday the average time was 50 minutes and we have to find the sample mean.
So, the values become
H(not):μ≤50
H(a):μ>50
Right Tail
The significance level, of the given number of employees then
α=0.05
And The value of sample mean, is
Z=x - u/i*(n)^1/2
then the value becomes
Z = 5.6 - 5/1.2*(25)^1/2.
then after calculating
Z= 1.6/1.2*5
Z= 0.26 And
Here The value of sample mean is 0.26.
So, The sample mean value is 0.26.
