This set of ratios are NOT proportional. If you were to cross multiply, you would get different products for each multiplication equation, symbolizing that these are not Proportional.

Answer:

Yes they are proportional!

The factors of 28 that we can use in these fractions are 4 and 7. To find if these are proportional, just simplify 8/28. To do so divide the numerator (top) and the denominator (bottom) both by 4...

8/28 / 4 = 4/7

Now that you have both with the same denominator, you can evaluate if 3/7 and 4/7 are proportional. In this case they are.

Hope this helps! :)

The value of a car with an initial purchase price of $18,250 depreciates by 11% per year.

larisa [96]

Step-by-step explanation:

This problem on depreciation of price.

Given data

initial price = $18,250

rate of depreciation = 11%

to solve for the new price we must find 11 percent of the initial price (depreciated value) and subtract from the initial price, we have

depreciation=

$\frac{11}{100} *18250\\0.11*18250= 2007.5$

Hence the depreciation= $2007.50

the new amount is $= initial amount - depreciation$

$=18250-2007.50\\= 16242.50$

the new amount is $16242.50

ME = 1.10.

Explanation:
The margin of error, ME, is given by the formula z*(σ/√n).

Since we want a 90% confidence interval, z=1.645.

σ=6, and n=80, giving us ME=1.645*(6/√80). This comes out to 1.10.

Answer:

Let AB be called x.

26/(18+x) = 14/x

14(18+x)=26x

252+14x=26x

252=12x

x=21
