Dafna1 [17]

Answer:

A) 0.15

B) 0.36

Step-by-step explanation:

First Box consist 1 red pills and 19 blue pills

second box consist 6 red pills and 14 blue pills

Third box consist 2 red pills and 18 blue pills

a) Prob ( randomly chosen pill is red) $= \frac{1}{3} \times \frac{1}{20} + \frac{1}{3} \times \frac{6}{20} + \frac{1}{3} \times \frac{2}{20}$

$\frac{1}{60} (1+6+2) = 0.15$

b)Prob ( 1 reds and 10 blue pilss) = $\frac{1}{3} \frac{^1C_1\times ^{19}C_{10}}{^{20}C_{11}} + \frac{1}{3} \frac{^6C_1\times ^{14}C_{10}}{^{20}C_{11}} + \frac{1}{3} \frac{^2C_1\times ^{18}C_{10}}{^{20}C_{11}}$

$= \frac{1}{3} 1.106 = 0.368$

Two numbers have a difference of 0.85 and a sum of 1 what are the numbers?

soldier1979 [14.2K]

X - y = 0.85
x + y = 1
----------------add
2x = 1.85
x = 1.85/2
x = 0.925

x + y = 1
0.925 + y = 1
y = 1 - 0.925
y = 0.075

so ur 2 numbers are : 0.925 and 0.075

Answer:

12) $\frac{7}{3} = \frac{b}{18}$

$3b = 126$

$\frac{3b}{3} = \frac{126}{3}$

$b = 42$

13) $\frac{3.6}{m} = \frac{1.2}{3.6}$

$1.2m = 12.96$

$\frac{12m}{12} = \frac{12.96}{12}$

$m = 10.8$

14) $\frac{16}{10} = \frac{n + 2}{5}$

$80 = 10n + 20$

$80 - 20 = 10n +20 -20$

$60 = 10n$

$\frac{60}{10} = \frac{10n}{10}$

$n = 6$

Laura retired from her job recently, and she has saved about $396,460.00 over the course of her career. She plans to withdraw $1

Tomtit [17]

So she has 396460
she will withdarw 1700 per month, and withdraw is loss or minus or (-)

after x months, she has 359060 left so

total-withdrawn=remaining
withdrawwn=1700 times months so withdrawn=1700x
total-1700x=remaining
total=396460
reaining=359060
subsitute
isolate x then divide is the strategy

396460-1700x=359060
add 1700x to both sides
396460=359060+1700x
subtract 359060 from both sides
37400=1700x
divide both sides by 1700
22=x

she has been retired for 22 months
