To figure this out youll have to multiply 64.80 by 2.5 first then youll get 162 after to figure out the answer you subtract 20 from that amount and get 142
Answer:
We conclude that the bowler's score is equal to 150 points.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 150
Sample mean, = 2 157
Sample size, n = 22
Alpha, α = 0.05
Population standard deviation, σ = 18
First, we design the null and the alternate hypothesis
We use Two-tailed z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
z-statistic lies within the range of acceptance region that is from -1.96 to 1.96, we fail to reject the null hypothesis and accept the null hypothesis.
Thus, bowler claims that her bowling score is not equal to 150 points is not true and we conclude that the bowler's score is equal to 150 points.
Answer:
3 1/3.
Step-by-step explanation:
2 2/3 + 2/3
= 6/3 + 2/3 +2/3
= 8/3 + 2/3
= 10/3
= 3 1/3.
For this case we have:
Let:
- s: Profit from sales in a given week
- e: Seller's weekly profit
Where "c" represents the commission.
The commission on sales can be observed with the application of a rule of three:
s ---------> 100%
c ---------> 4%
Thus, e is given by:
Answer:
The equation that models the relationship between her sales in a given week, s, and her weekly earnings, e is:
Option d
Answer:
Its 1
