Answer:
The monthly cost function for the scenario C(x,y) is;
C(x,y) = 70,000 + 2900x + 800y
Step-by-step explanation:
Let C represent the monthly cost in dollars.
x represent the number of performances by the cabaret artist per month
and y represent the number of hours of jazz per month
Given;
monthly costs of $70,000
regular cabaret artist is charging you $2900 per performance.
Per month = $2900x
your jazz ensemble is charging $800 per hour.
Per month = $800y
The monthly cost function for the scenario C(x,y) is the sum of all the costs;
C(x,y) = 70,000 + 2900x + 800y
Answer:
z-score value is 1.08
Step-by-step explanation:
The graph depicts the standard normal distribution with mean 0 and standard deviation 1. Shaded area is 0.8599.
So, We are given the shaded area and we need to find the z-score
Looking at the Positive z-score value, which is added in the figure:
z = 1.08
So, z-score value is 1.08
The ratio is
10 : 5.75
After simplifying the ratio you are left with
1.74 : 1
Answer:

Step-by-step explanation:
Train B's speed: 4/3 × 60 = 80
Combined speed = 80 + 60 = 120
Time = 240/120 = 2
