Answer:
f(x) * g(x)
Step-by-step explanation:
Hours worked per week = 45 hours
Weekly salary = $850 plus ;
3.5% commission on sales above $6,500
Given the functions :
f(x) = 0.035x and
g(x) = x - 6,500
and the fact that Joe’s dad sold enough this week to earn commission, which composition function represents Joe’s dad’s commissions ?
Commission = 3.5 / 100 = 0.035
Let his sales for the week = x ; since his sales exceeds 6,500
Hence, sales on which commission is payable is x - 6,500
Hence, commission for the week :
0.035 × (x - 6,500)
f(x) = 0.035 ; g(x) = (x - 6,500)
Composition function:
f(x) * g(x)
Ratio of the heights of two similar cones is 7/9
what is the ratio of their radii? ratio of their volumes??
TIA
If they are similar, the ratio of the radaii is the same.
Now consider that the volume of a cone is 1/3 PI r^2 * h
So the volume ratio will have a (7/9)^2 * 7/9 ratio
Answer:
The smallest sample size to satisfy the conditions is n=500.
Step-by-step explanation:
The condition for performing the inference related to the sample size is that, for all the categories, the expected success and failures in the sample are at least 10:

The largest sample size required will be for the minimum p or (1-p).
This happens to be the proportion that can play other instruments: 2%.
Then, we can calculate the minimum sample size as:
