If the ratio is 7:8, and the number of boys is 42, you would do 42 divided by 7, which equals 6. Then you do 8 times 6, and that's equal to 48. So the ratio is 42:48, with an amount of 48 girls.

natka813 [3]
A=P(1+ \frac{r}{n})^{nt}
A=futurer amount
P=present amount
r=rate in decimal
n=number of times compounded per year
t=time in years

A=2500
r=0.05
n=2
t=2

2500=P(1+ \frac{0.05}{2})^{(2)(2)}
2500=P(1+ 0.025)^{4}
2500=P(1.025)^{4}
2500=P(1.025)^{4}
divide both sides by [tex} 1.025^{4} [/tex]

Answer:

  Dawn has $1670 in account 1 and $1570 in account 2.

Step-by-step explanation:

Dawn can multiply the second equation by 8 and add 7 times the first equation.

  8(3/8A +7/8B) +7(A -B) = 8(2000) +7(100)

  10A = 16,700

  A = 1670

  B = 1570 . . . . 100 less than A

Dawn has $1670 in account 1 and $1570 in account 2.

__

<em>Check</em>

  3/8(1670) +7/8(1570) = 626.25 +1373.75 = 2000

A quarter back completes 29% of his passes. We want to observe this quarterback during one game to see how many pass attempts he
Ann [662]

Answer: P12* = 0.0164 or 1.64%

Therefore, the probability that it takes more than 12 attempts before he completes a pass is 0.0164 or 1.64%

Step-by-step explanation:

Given;

The quarterback's pass accuracy P= 29% = 0.29

The probability of not completing a particular pass P*

= 1 - 0.29 = 0.71

the probability that it takes more than 12 attempts before he completes a pass implies that the quarterback will not complete his first 12 pass attempts.

The probability that he will not complete the first 12 pass

P12* = (P*)^12

P12* = (0.71) ^12

P12* = 0.0164 or 1.64%

Therefore, the probability that it takes more than 12 attempts before he completes a pass is 0.0164 or 1.64%
