1. Rhode Island is the smallest state. It has an area of
approximately 1.55 x 10° square miles. Alaska is the largest
state. The area of Alaska is 4.28 x 10 times greater than the
area of Rhode Island.
What is the approximate area of Alaska in square miles?

663.4

Step-by-step explanation:

1.55 x 10 = 15.5

4.28 x 10 = 42.8

42.8 x 15.5 = 663.4

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;

40 x 50 = 2000
