Answer:
2 cases of granola bars
Explanation:
This is a classic system of equations type question.
24n + 20gb = 112 as she can only buy the items in these quantities and this is how many she bought in total
30n + 35gb = 160 as this is how much money she earns per case
I like to solve using elimination when possible. So we can multiply the first equation by 1.25
30n + 25gb = 140 then subtract this from the second equation
10 gb = 20 then divide by 10
gb = 2
Answer:
The answer is 0.9599.
Explanation:
mu (sample) = mu = 8.4
s.d. (sample) = 1.8/ sq. rt. 40
P( greater than 8.1) = (8.9-8.4)/(1.8/ sq. rt. 40)
Let x be the mean time for the 40 mechanics
Standardize the mechanics: (8.9-8.4)/(1.8/ sq. rt. 40) = 1.75 = Z
P( x > 8.9) = P(Z > 1.75), this means the area to the right of Z = 1.75.
Then you need to look in the table of the Normal distribution, Z(1.75) =0.9599
