To solve the question we proceed as follows:
z-score is given by:
z=(x-μ)/σ
where:
μ- mean
σ-standard deviation
The z-score of our information will be:
z=(65-64)/2.8
z=0.3571
thus the probability associated with this z-score is:
P(X≤x)=0.6404
Thus the <span>probability that the mean of any one of these 10 samples is greater than 65 inches will be:
P(X</span>≥x)=1-P(X≤x)
=1-0.6404
=0.3596
Answer:
B
Step-by-step explanation:
Consider this:
Cheese Dip --> Burrito --> Chicken
Cheese Dip --> Burrito --> Beef
Assume Cheese Dip is your starting point and Chicken / Beef are your ending points. We already have two combos here.
Now looking at the diagram, we should see eight ending points in total.
Therefore, there would be eight combinations for Lelia to choose.
To find volume the formula is V=Bh
B=area of the base which is A=bh
So, V=10*8*100
So the answer should be 8,000
