Answer: your total pay for the month is $3200
Step-by-step explanation:
You earn a base salary of $2200 a month plus a sales commission of 5%.
Your total sales for one month were $20,000. This means that your commission for that month would be
5/100× 20000 = 0.05 × 20000 = 1000
Total pay for the month would be
Base salary + commission for the month. Therefore, your total pay for the month would be
2200 + 1000 = $3200
= 2m - 9n - 6m + 3n - n
combine like terms (m with m terms and n with n terms)
= (2m - 6m) + (-9n + 3n - n)
add/subtract in parentheses
= -4m - 7n
ANSWER: -4m - 7n is the simplified expression

Answer:
Step-by-step explanation:
We want to determine a 98% confidence interval to estimate the true mean shear strength of anchor bolts.
Number of sample, n = 78
Mean, u = 4.25
Standard deviation, s = 1.3
For a confidence level of 98%, the corresponding z value is 2.33.
We will apply the formula
Confidence interval
= mean ± z × standard deviation/√n
It becomes
4.25 ± 2.33 × 1.3/√78
= 4.25 ± 2.33 × 0.147
= 4.25 ± 0.34
The lower end of the confidence interval is 4.25 - 0.34 = 3.91
The upper end of the confidence interval is 4.25 + 0.34 = 4.59
b) the confidence interval would still be valid because the number of samples is large(> 30)
