You have two decks of cards and you select a card from each deck. What is the probability to selecting a jack both times?

Answers

Answer:

The probability is 1/13 (1 to 13).

Step-by-step explanation:

In a card deck, there are 52 cards with 4 Jacks. If you simplified this probability, the answer would be 1 to 13.

4/52 = 1/13

In two card decks, there are 104 cards with 8 jacks.  If you simplified this probability, the answer would also be 1 to 13.

8/104 = 1/13

The height of the cylinder is 18 meters and the volume of the cylinder is 4,374 cubic meters. What is the area of the base of the cylinder?

Answers

Answer:

242.76m^2

Step-by-step explanation:

Given data

Height=18m

Volume=4,374m^3

We know that the expression for the volume of a cylinder is

V=πr^2h

substitute

4374=3.142*r^2*18

4374=56.556*r^2

4374/56.556=r^2

77.339=r^2

r=√77.339

r= 8.79m

But the area of a circle is expressed as

A= πr^2

A=3.142*8.79^2

A=3.142*77.2641

A=242.76m^2

Hence the area of the base is 242.76m^2

The compound interest on a sum of money in 2 yes and 4 yrs are 5460 and 12060.6 then find principle​

Answers

Answer:

2471.81

Step-by-step explanation:

Let I be the interest, r the annual rate and P the principal. Then:

I = P(r)^2 = 5460

I = P(r)^4 = 12060.6

so r^2 = P(r)^4 /  P(r)^2 = 12060.6/5460

r^2 = 2.2089

r = 1.486

So  P(r)^2 = P* 2.2089 = 5460

P = 5460 / 2.2089 = 2471.81.

The Ranallo family just bought a house. They qualified for an annual interest rate of 5.2% and their monthly payment

was $800 for a 30 year mortgage. Algebraically determine the amount of their loan to buy the house.

Answers

Answer:  your equation is poorly written/wrong hence I used the equation below

answer :  $289156.63

Step-by-step explanation:

applying the formula to calculate monthly repayment of Mortgage

M = P [ r(1+r)^n / ( ( 1+r )^n ) -1 ) ]  -----  ( 1 )

M = Total monthly payment = 800 * 12 * 30 = $ 288,000

P = ?

r = 5.2% / 12 = 0.4%

n = 30 * 12 = 360 months

Back to equation 1

P = M / [ r(1+r)^n / ( ( 1+r )^n ) -1 ) ]

   = 288000 / [ 0.004 ( 1.004)^360 / (( 1.004)^360 ) - 1 ) ]

   = 288,000 / -0.996  =  - $289156.63 ( It has a negative value because It is a loan borrowed )
