Suppose that there were a positive correlation between the variables u and v. If v is 24 when u is 10, which of these is most li

sveta [45]

Answer:

The correct answer is 48, given by option c.

Step-by-step explanation:

This question can be solved by proportions, using a rule of three.

Positive correlation means that the variables are directly proportional, and thus, we apply cross multiplication.

If v is 24 when u is 10, which of these is most likely to be the value of v when u is 20?

24 - 10

x - 20

Applying cross multiplication:

$10x = 24*20$

Simplifying both sides by 10:

$x = 24*2 = 48$

The correct answer is 48, given by option c.

Len [333]

Answer:

a) The cost of ribeye steak dinners is $ 16.96.

b) The cost of grilled salmon dinners is $ 23.37.

Explanation:

Let the cost for ribeye steak dinners be m and cost for grilled salmon dinners be n.

A waitress sold 10 ribeye steak dinners and 18 grilled salmon dinners, totaling $590.39 on a particular day.

So, we have

10 m + 18 n = 590.39 -------equation 1

Another day she sold 22 ribeye steak dinners and 9 grilled salmon dinners, totaling $583.49

So, we have

22 m + 9 n = 583.49 -------equation 2

equation 2 x 2

44 m + 18 n = 1166.98 -------equation 3

equation 3 - equation 1

44 m + 18 n - ( 10 m + 18 n ) = 1166.98 - 590.39

m = 16.96 $

Substituting in equation 1

22 x 16.96 + 9 n = 583.49

n = 23.37 $

a) The cost of ribeye steak dinners is $ 16.96.

b) The cost of grilled salmon dinners is $ 23.37.

A house is being purchased at the price of $138,000.00. The 30-year mortgage has a 10% down payment at an interest rate of 4.875

Mama L [17]

Answer:

$238,600

Step-by-step explanation:

The amount being borrowed is 100% -10% = 90% of the purchase price, or ...

0.90 × $138,000 = $124,200.

Then the monthly payment can be computed using the amortization formula:

A = P(r/12)/(1 -(1 +r/12)^(-12t))

A = 124200(.04875/12)/(1 -(1 +.04875/12)^(-12·30)) ≈ 657.28

and the total repaid is ...

(360 months) × ($657.28/month) = $236,619.58*

The cost of mortgage insurance is considered part of the cost of the loan. That amount is ...

(77 months) × ($25.88/month) = $1992.76

so the total amount paid for the loan is ...

$236,619.58 +1992.76 = $238,612.34

The cost of the loan is about $238,600.

_____

* In figuring the total repayment cost, we used the full-precision value for the loan payment. The actual repayment amount will depend on the rounded value of the loan payment and the way the final payment is made. When rounded to the nearest $100, these details become unimportant.
