She continued to mow all of the yards each week for a total of 555 weeks, earning money at the same rate. At the end of the 555 weeks, she spent \$250$250dollar sign, 250. Which numerical expression shows the amount of money Louise has left? Choose 1
A
5\times({25} + 75) - {250}5×(25+75)−2505, times, left parenthesis, 25, plus, 75, right parenthesis, minus, 250

(Choice B)
B
250 - (5\times{25}) + 75250−(5×25)+75250, minus, left parenthesis, 5, times, 25, right parenthesis, plus, 75

(Choice C)
C
(5\times{25}) + 75 - {250}(5×25)+75−250

step-by-step explanation: 4 cause 2+2=4

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;

s
