How many semiannual periods are there in 20 years... 20×2 = 40

FW = PW(1+i)^N
FW = $3500(1+0.03)^40

solve for FW
(sorry no calculator on me)

Tell what you would do to isolate the variable. -5c = 5/24

Masteriza [31]

To isolate the variable here is what you would do:

−5c= $\frac{5}{24}$

Step 1: Divide both sides by -5.

$\frac{-5c}{-5}$ = $\frac{5}{24}$ (A five was supposed to go underneath the 24 to show the division but whatever)

Answer: c= $\frac{-1}{24}$

Pick 3 cards from a standard 52-card deck. Find the P(of at least 1 red card).

kkurt [141]

Answer:P(BBR) = 1/2 × 25/51 × 26/50 = 13/102 if cards are not replaced.

P(RBB) = 1/2 × 26/51 × 25/50 (simplified 1/2) = 13/102

P(BRB) = 1/2 × 26/51 ×25/50 (simplified 1/2) = 13/102

Step-by-step explanation: P(B) at first step is 26 cards out of a possible 52 therefore 26/52 (or simplified 1/2). We then have 25 black cards left out of a possible 51 therefore 25/51. The final card then has to be red to meet the criteria, we have 26 red cards still out of a possible 50 therefore 26/50.

This would be an example of binomial probability as at each step there are only 2 options R or B.

the lengths of the side of a rectangular window have the ratio 1.7 to 1 the area of the window is 2,720 sqaure inches what are d

nignag [31]

Answer:

$Lenght: 68\ in\\\\Width: 40\ in$

Step-by-step explanation:

The formula for calculate the area of a rectangle is:

$A=lw$

Where "l" is the lenght and "w" is the width.

You know that the ratio of the sides of the rectangular window is:

$1.7:1$

Then, let be $x$ the width (in inches) of the rectangular window and $1.7x$ the lenght (in inches) of the rectangular window.

Knowing that the area of the window is 2,720 square inches, you can know that:

$(1.7x)(x)=2,720$

Now you must solve for "x" in order to find the width:

$(1.7x)(x)=2,720\\\\1.7x^2=\\\\x=\sqrt{\frac{2,720}{1.7} }\\\\x=40$

Finally, the lenght is:

$1.7x=1.7(40)=68$
