Answer:

133 girls

Step-by-step explanation:

Total members = x

Number of boys = \frac{2}{9}x

Number of girls = \frac{2}{9}x +95

Number of boys + Number of girls = total members

\frac{2}{9}x+\frac{2}{9}x+95=x\\\\\frac{2}{9}x+\frac{2}{9}x=x -95\\\\\frac{2}{9}x+\frac{2}{9}x-x=-95\\\\\frac{4}{9}x-x = -95\\\\\frac{4}{9}x-\frac{9}{9}x = -95\\\\\frac{-5}{9}x=-95\\\\x = -95*\frac{9}{-5}\\\\x=19*9

x = 171

Number of boys = \frac{2}{9}*171 = 2 * 19 = 38

Number of girls = 38 + 95   = 133

Answer:

1/21

Step-by-step explanation:

Cards: 2,3,4,5,6,7,8      7 cards

1st card :5

P(5) = number of 5's / total

       = 1/7

Then we keep the card

Cards: 2,3,4,6,7,8   only 6 cards left

card less than 4: 2,3

P (card less than 4)  = number of cards less than 4/ total cards

                                  = 2/6 = 1/3

P (5, no replacement, card less than 4) = P(5) * P( less than 4)

                                                                 = 1/7 * 1/3

                                                                  =1/21

5. Amy deposited $7,000 in a bank account earning 3.5% interest, compounded
Semenov [28]

Answer:

Step-by-step explanation:

Given the following data;

Principal = $7,000

Interest = 3.5% = 3.5/100 = 0.035

To find the future value, we would use the compound interest formula;

A = P(1 + \frac{r}{n})^{nt}

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

n is the number of times the interest is compounded in a year.

t is the number of years for the compound interest.

Substituting into the equation, we have;

A = 7000(1 + \frac{0.035}{n})^{nt}

g Disco Fever is randomly found in one half of one percent of the general population. Testing a swatch of clothing for the prese
Marizza181 [45]

Answer:

The probability that the result is positive is P=0.04475=4.475%.

Step-by-step explanation:

We have the events:

D: disease present

ND: disease not present

P: test positive

F: test false

Then, the information we have is:

P(D)=0.005

P(P | D)=0.99

P(P | ND)=0.04

The total amount of positive test are the sum of the positive when the disease is present and the false positives (positive tests when the disease is not present).

P(P)=P(P | D)*P(D)+P(P | ND)*(1-P(D))\\\\P(P)=0.99*0.005+0.04*0.995\\\\P(P)=0.00495+0.0398=0.04475

The probability that the result is positive is P=0.04475.
