Andrew is paid $4 per hour for the first 30 hours he works each week. He makes $5 per hour for each hours he works over 30 hours per works. in other words, total wages = fixed wages for 30 hours + additional wages at $5 per hours. Apply function notation to answer the following questions about Andrew's wages.

Part A:
write a function thst gives Andrew's total wages when he works more 30 hours. use the variables w for wages and h for hours.

Step-by-step explanation:

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
