The scale given (1 in : 1/2 ft) implies that 1 inch on the model is equal to 1/2 foot on the actual ship. Therefore, we can multiply the two inch values by 1/2 foot to find the true dimensions of the ship in feet. Starting with 28 inches:

28 × (1/2 ft) = 14 ft

28 inches is proportional to 14 feet. Now calculate 65 inches:

65 × (1/2 ft) = 32.5 ft

65 inches is proportional to 32.5 feet. Therefore, the answer to this problem is:

D) 14 ft. by 32 1/2 ft.

I hope this helps!

Answer:

a) 97.37%

b) 1.31%

Step-by-step explanation:

Here we want to calculate the area under the Normal curve with mean 0.52 and standard deviation 0.009 between 0.5 and 0.54

This can be easily done with a spreadsheet and we get

P (0.5くV < 0.54) = 0.9737 or 97.37%

(See picture 1)

Here we want the area under the Normal curve with mean 0.52 and standard deviation 0.009 to the left of 0.5.

P(V ≤ 0.5) = 0.0131 or 1.31%

(See picture 2)
