A study of immunizations among school-age children in California found that some areas had rates of unvaccinated school-age children as high as 13.5%. Imagine a district in the state where 13.5% of children are unvaccinated. If three children are chosen randomly (assume they are not siblings) from this district, what is the probability that all three children have been vaccinated

Answers

Answer 1

Answer: 0.6472

Step-by-step explanation:

Given: The proportion of unvaccinated school-age children = 13.5%

Then, the  proportion of vaccinated school-age children :p=100%-13.5%

= 86.5% = 0.865

Total children selected :n=3

Binomial probability formula:

[tex]P(X=x)=\ ^nC_xp^x(1-p)^{n-x}[/tex]

The probability that all three children have been vaccinated :

[tex]P(X=3)=\ ^3C_3(0.865)^3(0.135)^0\\=(1)(0.647214625)\approx0.6472[/tex]

Hence, the required probability = 0.6472

112 * 2 = 224

280 + 160 + 224 = 664

Therefore, your answer would be B. 664 square inches.

1. Mike’s rectangular dining room is 8 feet wide and 6 feet long. Mike wants to install a new wood floor and new base boards. It will cost $10.00 per square foot for the new flooring.

a. How many square feet of flooring does Mike need to purchase? SHOW YOUR WORK



b. Use the information from part a to answer, how much will it cost Mike for the new flooring? SHOW YOUR WORK



c. How much base board would Mike need to purchase to go around the perimeter of the dining room? SHOW YOUR WORK

Answers

Answer:

a:

to find area we need to multiply width by length

so lets multiply 8×6

so we will get 48 feet

b:

the area is 48 feet, and we know that it costs 10$ per

square foot

so we will multiply 48×10

so we will get 480$

c:

the premiter = all sides added to gather

in a rectangle we have 4 sides, 2 width and 2 length

so the answer will be (8×2)+(6×2)

so the answer will be 16+12=30

10. In this university, among all students, 15% are senior, 25% are junior, 25% are sophomore, and so 35% are freshmen. Among senior, 40% have scholarship; among junior, 30% have scholarship; among sophomore, 20% have scholarship, and among freshmen, 10% have scholarship. Among those have scholoarship, what is the percentage of studens who are senior

Answers

Answer:

27.27% of the students with scolarship are seniors.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Has scolarship

Event B: Is a senior

15% are senior, and of those, 40% have scolarship. So

[tex]P(A \cap B) = 0.15*0.4 = 0.06[/tex]

Probability of a scolarship:

15% of 40%(seniors)

30% of 25%(juniors)

20% of 25%(sophmores).

10% of 35%(freshmen). So

[tex]P(A) = 0.15*0.4 + 0.3*0.25 + 0.2*0.25 + 0.1*0.35 = 0.22[/tex]

Percentage:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.06}{0.22} = 0.2727[/tex]

0.2727*100 = 27.27%

27.27% of the students with scolarship are seniors.

Answers

Answer:

[tex]Unused = \frac{1}{12}m[/tex]

Step-by-step explanation:

Given

[tex]Total= \frac{3}{4}m[/tex]

[tex]Used= \frac{2}{3}m[/tex]

Required

Determine the part left

The part left is calculated using:

[tex]Used + Unused = Total[/tex]

[tex]Unused = Total - Used[/tex]

[tex]Unused = \frac{3}{4}m - \frac{2}{3}m[/tex]

Take LCM

[tex]Unused = \frac{9m - 8m}{12}[/tex]

[tex]Unused = \frac{1m}{12}[/tex]

[tex]Unused = \frac{1}{12}m[/tex]

The Howard’s are saving up to go on a family vacation in 2 years. They invest 2300 into an account with an annual interest rate of 1.23%

Answers

Answer:

$2384.87

Step-by-step explanation:

Given data

P=2300

t= 2 years

r= 1.23%

Required

The amount in their account

Let us apply the simple interest formula

A=P(1+rt)

Substitute

A= 2300(1+0.0123*3)

A= 2300(1+0.0369)

A= 2300*1.0369

A=$2384.87

Hence the amount in the account is $2384.87
