Are being a girl and playing a sport independent events? Why or why not?

Answers

Being a female and participating in sports are independent events for the provided data because P(girl) = P(girl participates in sports)

What are independent events?

These are the occurrences that are independent of other occurrences.

Occurrences A and B are independent events when the likelihood of one occurring is unaffected by the occurrence of the other.

Probability of independent events formula:

"P(A∩B) = if A and B are independent occurrences P(A).P(B)

What exactly is probability?

Finding the chance that an event will occur is the focus of this area of mathematics."

P(A) = n(A)/n(S), where n(A) is the number of positive outcomes and n(S) is the total number of possible outcomes for an event A.

For given question,

We have been given a table that shows the results broken down by gender.

Total          171                            104                     275

Using the definition of probability:

⇒ P(girl)  = Number of girls/ Number of students

⇒ P(girl) = 135/275

P(girl) = 0.49                    ....................(1)

Now we find the probability of girls that play a sport.

Using the definition of probability:

P(girl plays a sport)

= Number of girls who plays a sport/ number of students who plays a sport

= 76/ 171

= 0.44                                    ......................(2)

Answers

Percent is from the Latin adverbial phrase per centum meaning “by the hundred.”

What is percentage?In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.percentage, a relative value indicating hundredth parts of any quantity. One percent (symbolized 1%) is a hundredth part; thus, 100 percent represents the entirety and 200 percent specifies twice the given quantity.Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100. The formula used to calculate percentage is: (value/total value)×100%.

Suppose that you’d like to retire in 40 years and you want to have a future value of $ 500000 in a savings account. Also suppose that your employer makes regular monthly payments into your retirement account.
If you can expect an APR of 7% for your account, how much do you need your employer to deposit each month?

Employer Contribution =

The formulas we have been using assume that the interest rate is constant over the period in question. Over a period of 40 years, though, interest rates can vary widely. To see what difference the interest rate can make, let’s assume a constant APR of 4% for your retirement account. How much do you need your employer to deposit each month under this assumption?

Employer Contribution =

Answers

a) If only your employer makes the monthly deposits into your retirement account for the future value of $500,000 in 40 years at 7% APR, your employer contributions should be $190.49.

b) If only your employer makes the monthly deposits into your retirement account for the future value of $500,000 in 40 years at 4% APR, your employer contributions should be $423.03.

What is the future value?

The future value represents the amount expected to be the balance in the investment account after a period.

The future value can be used to determine the periodic payments required to meet the target balance, using an online finance calculator.

Periodic Deposits at 7%:

N (# of periods) = 480 months (40 years x 12)

I/Y (Interest per year) = 7%

PV (Present Value) = $0

FV (Future Value) = $500,000

Results:

PMT (Periodic deposits) = $190.49

Sum of all periodic payments = $91,435.07

Total Interest = $408,564.93

Periodic Deposits at 4%:

N (# of periods) = 480 (40 years x 12)

I/Y (Interest per year) = 4%

PV (Present Value) = $0

FV (Future Value) = $500,000

Results:

PMT (Periodic deposits) = $423.03

Sum of all periodic payments = $203,052.33

Total Interest = $296,947.67

What are combinations ?

A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter. In combinations, you can select the items in any order.

Combinations can be confused with permutations. However, in permutations, the order of the selected items is essential. For example, the arrangements ab and ba are equal in combinations (considered as one arrangement), while in permutations, the arrangements are different.

Given: A password is required to log into a system that only recognizes numbers and letters of the alphabet

Since , there are total 26 letters and 10 numbers are possible that can be used to create a password . Hence , there are 36 character in total to be used.

Also , repetition of character is not allowed. Therefore , the chance of selecting every character decreases by 1 in comparison to its preceding character .

Chance of selecting first character = 36

Chance of selecting second character = 35

Similarly for seventh = 30

Thus , different passwords that are possible  using 7 numbers or letters, without reusing any of them = 36*35*34*33*32*31*30 = 42,072,307,200 .

82.9 score should be assigned for A’s and 74.4 should be assigned for B’s

In this question we have been given the scores of students on a test are normally distributed with a mean score of 70 points and a standard deviation of 10 points.

It is decided to give A’s to 10 percent of the students and B’s to 23 percent of the students.

We need to find what scores should be assigned A’s and B’s.

μ = 70, σ = 10

Using standard normal table,

P(X > x) = 10%

P(X > x) = 0.10

1 - P(X ≤ x) = 0.10

P(X ≤ x) =1−0.10

             =0.90

Using standard normal z table,

(x - 70)/10 = 1.29

x = 82.9 (score for A’s)

Now, P(X > x) = 33% (top 33% = 10% for A’s+23 % for B’s)

P(X>x) = 0.33

1 - P(X ≤ x) = 0.33

P(X ≤ x) = 1 - 0.33

             = 0.67

Using standard normal z table,

(x - 70)/10 = 0.44

x = 74.4 (score for B’s)

A new computer game costs $160,000 to research and develop. Once completed, individual games can be produced for just $.20 each. If the first 275 are given away as samples, how many games must be sold for the average price to be $2?

Answers

Answer: The correct answer is (d) 89,200 games.

To find the number of games that must be sold, we need to set up an equation to represent the total revenue from the game sales and solve for the number of games sold.

The total revenue from the game sales is equal to the number of games sold multiplied by the price per game, minus the cost of research and development.

Let X be the number of games sold

Total revenue = X * $2 - $160,000

We also know that the total cost of producing the games is equal to the number of games produced multiplied by the cost per game.

Total cost = X * $0.20

We can set the total revenue equal to the total cost and solve for X:

X * $2 - $160,000 = X * $0.20

X = 89,195

Since we gave away the first 275 games for free, we need to add 275 to the number of games sold to find the total number of games that must be sold.

Total number of games sold = X + 275 = 89,195 + 275 = 89,470

Therefore, the correct answer is (d) 89,200 games.

Answers

The rate of change is 7 more of function A than the slope of function B.

What is meant by slope?

Slope is calculated as the ratio of "vertical change" to "horizontal change" between any two points on a line, or any two points. When the ratio is expressed as a quotient ("rise over run"), the same number is provided for every two distinct locations on the same line. There is a negative "rise" on a descending line.

Since y=8x+3,

The rate of change in equation A is equal to the slope m m=8.

The rate of change, m=1, is given in equation B.

y=mx+ is the solution to equation B.

By substituting the values we get,

y=x+4

Calculate the difference between the rates of change of function A and function B.

Two machines produce sound pressure levels of approximately 80 dB(A) each. What is their approximate combined sound pressure level?

Answers

83.01dB is approximate combined sound pressure level.

What is sound pressure level?

The result of the pressure changes in the air caused by sound waves is sound pressure, often known as sound pressure level. The hearing threshold is the lowest sound pressure that a human can hear, and the pain threshold is the maximum sound pressure that a person can tolerate.

The difference between sound pressure at the pain threshold and the hearing threshold is a million times higher.

We have sound pressure level denoted as (Lp) of each machine

i.e 80 dB,(given).

Therefore, we can calulate sound pressure level from both machines combined by given formula,

SPL = 10 * Log(10^(SPL(1) /10)  + 10^(SPL(2) /10) +10^(SPL(3) /10) + ............)

   where,

      SPL= sound pressure level(dB)

 => SPL = 10 * Log(10^(80 /10) + 10^(80 /10))

 => SPL = 10 * Log(10^8 + 10^8)

 => SPL = 10 * 8.301

 => SPL = 83.01dB

Hence, 83.01dB is approximate combined sound pressure level.

What is the solution to 9|x – 8| < 36?

4 < x < 12
x < –4 or x > 12
x > –12 or x < 8
–4 < x < 8

Answers

Answer:

4 < x < 12

Step-by-step explanation:

x - 8 ≥ 0

x ≥ 8

If x ≥ 8

9(x-8) < 36

9x - 72 < 36

9x < 36 + 72

9x < 108

9/9 x < 108/9

x < 12


8 ≤ x < 12


if x < 8

9(-x+8) < 36

-9x + 72 < 36

-9x < 36 - 72

-9x < -36

-9/-9 x > -36/-9

x > 4


4 < x < 8

4<x<12

Answer:

  a.  18.5 million

  b.  2002

Step-by-step explanation:

Given that A = 18.5·e^(0.1708t) models a population t years after 2000, you want to know the population in 2000 and when it will reach 26.6 million.

Population in 2000

The year 2000 is 0 years after 2000, so we can find the population using t=0 in the given equation.

  A = 18.5·e^(0.1708·0) = 18.5·e^0 = 18.5

The population in 2000 was 18.5 million.

Year of 26.6 million

We can solve for t to find the year in which the population reached 26.6 million:

  26.6 = 18.5·e^(0.1708t)

  26.6/18.5 = e^(0.1708t)

  ln(266/185) = 0.1708t

  t = ln(266/185)/0.1708 ≈ 2.13 . . . . . . 2.13 years after 2000

The population will reach 26.6 million in the year 2002.

Additional comment

The population of 26.6 million represents about a 44% increase over the initial population of 18.5 million. The exponential term tells you the rate of growth is 17.08% compounded continuously. Thus we expect the larger population to be reached in a time slightly less than 44/17 ≈ 2.6 years.

(These numbers were found using a calculator. It is sufficient to do the estimating by realizing that 1.50·18 = 27, and 17·3 = 51, so the growth to 26.6 from 18.5 is less than 50% and will take less than 3 years.)

The events P(A) = 0.22 P(B) = 0.45, P(A and B) = 0.099 and rolling a pair of dice at the same time are independent events. Others are dependent events.

What is Independent and Dependent Events?

Independent events are events for which the occurrence of this event does not depend on any other events.

Dependent events are those events for which it's occurrence depends on other events.

Two events A and B are independent, if

P(A | B) = P(A)

P(A and B) = P(A) × P(B)

P(A) = 0.65, P(B) = 0.25 and P(A and B) = 0.40

P(A) × P(B) = 0.65 × 0.25 = 0.1625 ≠ P(A and B)

∴ A and B are dependent events.

P(A) = 0.22 P(B) = 0.45 and P(A and B) = 0.099

P(A) × P(B) = 0.22 × 0.45 = 0.099 = P(A and B)

∴ A and B are independent events.

P(A) = 0.42 P(B) = 0.62 and P(A| B) = 0.2604

P(A| B) = 0.2604 ≠ P(A)

∴ A and B are dependent events.

If you roll a pair of dice at the same time, probability for any number to occur on dice 1 does not affect the probability of any number to occur on dice 2.

∴ A and B are independent events.

If you choose two marbles from a bag, when the first marble is chosen, then the second marble you choose will not be the first marble in any case. So second event depends on the first event.

∴ A and B are dependent events.

Hence, as P(A and B) = P(A) × P(B) satisfies for the events P(A) = 0.22 P(B) = 0.45, P(A and B) = 0.099, is is independent events. Also rolling a pair of dice at the same time is also independent events. The rest of the events are dependent events as it does not satisfies the condition for independent events.
