According to the Center for Disease Control and Prevention (CDC), up to 20% of Americans contract the influenza virus each year,
12345 [234]

Answer:

(1) a. 0.0009

(2) d. 0.640

(3)

  • a. P(A and B) = 0.06.
  • b. P(A or B) = 0.70.

(4)Not disjoint

(5) a. nearly 0.

(6)b. 0.919

Step-by-Step Explanation:

(1)Probability of a baby being born with a birth defect =3%=0.03

The probability that both babies have birth defects=0.03 X 0.03= 0.0009.

(2)The probability of contracting the influenza virus each year = 20%=0.2

Therefore, the probability of not contracting the influenza virus =1-0.2=0.8

The probability that neither baby catches the flu in a given year:

=0.8 X  0.8

=0.64

(3)

P(A)=0.1

P(B)=0.6

P(A or B)=P(A)+P(B)=0.1 + 0.6 =0.7

P(A and B)=P(A)XP(B)=0.1 X 0.6 =0.06

(4)

P(A)=0.2

P(B)=0.9

Event A and B cannot be disjoint.

(5)

The probability of an American woman aged 20 to 24 having Chlamydia infection  =\dfrac{2791.5}{100000}

The probability that three randomly selected women in this age group have the infection

=\dfrac{2791.5}{100000} \times \dfrac{2791.5}{100000} \times \dfrac{2791.5}{100000} \\\\=0.00002175\\\approx 0

(6)The probability of an American woman aged 20 to 24 not having Chlamydia infection  =1-\dfrac{2791.5}{100000}

The probability that three randomly selected women in this age group do not have the infection

=\left(1-\dfrac{2791.5}{100000}\right)^3\\\\=0.9186\\\approx 0.919

Camden is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 5 points. What would
serg [7]

Answer:

40/50

Step-by-step explanation:

The test is worth 50 points in total. Each question is worth 5 points. So,

50 points ÷ 5 points each = 10 questions

If he gets 2 questions wrong,

10 - 2 = 8

He got 8 out of 10 questions right.

Now, multiply by 5 to find his test score out of 50.

8 × 5 ÷ 10 × 5

= 40/50

His test score would be 40/50.

Hope that helps.

Please help giving brainliest
Kitty [74]

Answer:

7. D) 180

7. C) 24%

7. D) 2 out of 9

7. D

Step-by-step explanation:

36 doesn't go into 5

45 doesn't go into 4

60 doesn't go into 9

180/4 = 45

180/3 = 60

180/5 = 36

180/9 = 20

We can make this problem even easier by converting the denominator from 25 to 100. This can be done with multiplication (x4)

Whatever you do to the denominator, you must also do to the numerator, so if we multiply both sides by 4, we get 24/100, which is equivalent to .24

total: 81 pieces of jewelry

18/81 or 2/9 (divide numerator and denominator both by 9)

.67 = 67/100

.607 = 607/1000 or 60.7/100

.07 = 7% or 7/100

.067 = 6.7% or 6.7/100
