The Brown’s used 50 feet of rope to surround their rectangular garden. The length of the garden is 4 times as much as its width. What is the length and width of the garden, in feet?
Length =

Width =

Area =

Length : 20   Width : 5     Area : 100

Step-by-step explanation: Since it states that the length is four times as much as the width, you can add those two (soon to be dividends) together to get 5. However, you have to add the other side to the current one to get your entire dividend of 10. Now divide 50 by 10 to get 5. Lastly, multiply five by the other factor. (4 for length, 1 for width)

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;
