60 points! A designer builds a model of a sailboat. The finished model is exactly the same shape as the original, but smaller. The scale factor is 2:13.
(a) Find the ratio of the volume of the model to the volume of the original.
(b) Find the ratio of the surface area of the model to the surface area of the original.
(c) Find the ratio of the width of the model to the width of the original.
Write these ratios in the format m:n.
volume:
surface area:
width:

only 10/60 isn't equivalent

hope this : )

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;

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

step-by-step explanation:

the answer is $42.96
