You invest $5,000 in an account earning simple interest. the balance after 6 years is $6,200. what is the interest rate?

patriot [66]

F=p(1+rt)
6200=5000(1+6r) divided both sides by 5000

1.24=1+6r
1.24-1=6r
6r=0.24
R=0.04*100=4%

What value of t is a solution to this equation?<br><img src="https://tex.z-dn.net/?f=%5Cfrac%7Bt%7D%7B2%7D%20-16%3D-18" id="TexF

klemol [59]

Answer:

t= -4

Step-by-step explanation:

t/2-16= -18

first add 16 to both sides

t/2-16+16= -18+16

t/2= -2

now multiply both sides by 2

(t/2)2=-2(2)

t= -4

answer check:

substitute the variable for -4

-4/2-16= -18

-4/2= -2

-2-16= -18

-18= -18

Ponderosa Paint and Glass carries three brands of paint. A customer wants to buy another gallon of paint to match paint she purc

sveta [45]

Answer:

$\frac{4}{9}$

Step-by-step explanation:

Two events are independent of each other, this is called Compound Probability. Classical example is if two coins are filped, what is the probability of getting two heads in a row.?

Answer: each has 50% probability because there are two states only, either H or T. since we have two coins the probability of getting two heads in row is the product of obtaining heads for each individual coin (which is independent of each other). or is $\frac{1}{2}$ × $\frac{1}{2}$ = $\frac{1}{4}$ = 25%. (Notice!).

Back to our problem, now here we have 3 paint brands and one of them is the right paint brand and two of them are not correct brands. so the prabablity that the customer has picked not correct brand is $\frac{2}{3}$ and her husband has not picked correct brand is also $\frac{2}{3}$ , since two probabilities are compound probabilities i.e indepandant of each other the probablity that both woman and her husband fail get correct brand is the product of the two and is = $\frac{2}{3}$ × $\frac{2}{3}$ = $\frac{4}{9}$ .
