A group of students wants to put mulch in some flower beds near their school. It will take 100 cubic feet to mulch the entire flower bed. Company A sells bags of mulch for $2 per cubic foot. Company B will deliver a truckload at $1.50 per cubic foot, but charges a $50 delivery fee. Write an equation to model each situation. Then decide which company should be used. Are there other factors to consider other than cost? Explain your thinking.

Note that one cubic yard of mulch (often just called "a yard") is 27 cubic feet. Most bags of mulch hold 2 cubic feet. So there are 13-1/2 bags of mulch in a yard. An organic mulch, such as bark mulch and pine straw, offers many benefits to plants and soil.

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;
