Acompany charges $8 an hour for lawn mowing. what would the company charge for a lawn that takes 1 hour and 45 minutes to mow?

there are 60 minutes in an hour so

t = 1 45/60  = 1 3/4

t = (4 * 1 + 3)/4  = 7/4

$ 8* 7/4 = 56/4 = $14

they will charge $14.00

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;
