The Shapes Are Similar Find the Scale Factor

A.3

Step-by-step explanation:

To get the answer first divide 3 by 1 which is 3. Then Divide 6.9 by 2.3 which is also 3. Therefore, your answer is 3

Step-by-step explanation:

the scaled image is 1/3 of the original

(6.9 : 3 = 2.3 and 2.3 : 1 = 2.3)

is this part of a question or something

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;
