suppose a jar contains 11 red marbles and 40 blue marbles. if you reach in the jar and pull out 2 marbles at random, find the probability that both are red. write your answer as a reduced fraction.
Answers
The required probability that both are red out of total marbles is 0.0431 or 4.31%.
What is probability?A probability is a number that mirrors the opportunity or probability that a specific occasion will happen. Probabilities can be communicated as extents that reach from 0 to 1, and they can likewise be communicated as rates going from 0% to 100 percent.
According to question:Total number of marbles in a jar = 40 + 11 = 51
Number of red marbles = 11, blue marbles = 40
At our first pull, there is an 11/51 chance that a red will be pulled and in second pull the probability is 10/50 , as one red marbles taken out.
Net probability = 11/51×10/50 = 0.0431

Joan wants to have $250,000 when she retires in 29 years. How much should she invest annually in her sinking fund to do this if the interest is 4% compounded annually?
Answers
Joan should invest $4720 annually in her sinking fund to have $250,000 when she retires
Calculating the amount to investWe can use the future value formula for an annuity to solve this problem:
FV = PMT * [(1 + r)^n - 1] / r
Where:
FV = future valuePMT = annual paymentr = interest raten = number of periodsWe want to find PMT, so we can rearrange the formula:
PMT = FV * r / [(1 + r)^n - 1]
Plugging in the values we know:
FV = $250,000
r = 0.04
n = 29
PMT = $250,000 * 0.04 / [(1 + 0.04)^29 - 1]
PMT = $250,000 * 0.04 / 22.718
PMT = $4720
So Joan should invest approximately $4720 annually in her sinking fund to have $250,000 when she retires in 29 years, assuming an interest rate of 4% compounded annually.

28 grams per cubic meter. ) Then write a composite function in simplest form in
which the domain values represent the radius of the cylinder and the range values
represent the mass of the water in the cylinder. Write your response in terms of pi
Answers
We can create three functions related to the manufacturing of acrylic cylinders: V(r), which calculates the volume of water based on the radius of the cylinder; M(V), which calculates the mass of water based on the volume; and a composite function that combines the two. The composite function will take the radius of the cylinder as the input and provide the mass of the water in the cylinder as the output. These functions can be expressed in terms of pi and the given density of water (28 grams per cubic meter).
To explain the functions, let's start with V(r). Since the height of the cylinder is always twice the radius, we can express the volume using the formula for the volume of a cylinder: V(r) = pi * r^2 * h. Substituting the relationship between the height and radius, the formula simplifies to V(r) = pi * r^2 * (2r), which further simplifies to V(r) = 2pi * r^3.
Next, we have M(V) to calculate the mass of water based on the volume. Since the density of water is approximately 28 grams per cubic meter, we can express the mass as M(V) = V * density. Substituting the value of V from the previous function, we get M(V) = (2pi * r^3) * 28.
Finally, the composite function takes the radius of the cylinder as the input and provides the mass of water in the cylinder as the output. Therefore, the composite function can be written as M(r) = (2pi * r^3) * 28, where M(r) represents the mass of water in the cylinder given the radius r.

Assume you can earn 0.8% per month in the stock market by investing in S\&P500; assume you buy $10,000 worth of an index ETF that represents the S\&P 500 . When you get to age 67 , how much is your investment worth? (The future value of $10,000, monthly compounding). 2. Assuming the same age as above in Q1, you can earn 10% per year in the stock market by investing in S\&P500; assume you buy $10,000 worth of an index ETF that represents the S\&P500. At your retirement age of 67 , the value of this $10,000 investment is $350,000.00. What is the average rate of return on your investment?
Answers
The investment will be worth approximately $28,940 at age 67. The average rate of return on the investment is approximately 5.59%.
To calculate the future value of an investment and the average rate of return, we'll consider two scenarios: one with monthly compounding and one with annual compounding.
1. Monthly Compounding:
Given that you earn 0.8% per month in the stock market, we can calculate the future value of your $10,000 investment when you reach age 67. Since we don't have the exact age, we'll assume it to be 21 years and 1 month for this calculation.
To calculate the future value with monthly compounding, we use the formula:
FV = PV * (1 + r)^n
Where:
FV = Future Value
PV = Present Value (initial investment)
r = Monthly interest rate
n = Number of compounding periods
In this case, PV = $10,000, r = 0.008 (0.8% monthly interest rate), and n = (67 - 21) * 12 (number of months from age 21 to 67).
Using the formula, we can calculate the future value:
FV = $10,000 * (1 + 0.008)^((67 - 21) * 12)
We can simplify the equation and calculate the value:
FV ≈ $10,000 * (1.008)^576
FV ≈ $10,000 * 2.894
FV ≈ $28,940
Therefore, the investment will be worth approximately $28,940 at age 67.
2. Annual Compounding:
Given that the value of your $10,000 investment at age 67 is $350,000, we can calculate the average rate of return over the investment period.
To calculate the average rate of return, we use the formula:
Average Rate of Return = (FV / PV)^(1/n) - 1
Where:
FV = Future Value
PV = Present Value (initial investment)
n = Number of years
In this case, FV = $350,000, PV = $10,000, and n = 67 - 21 (investment period).
Using the formula, we can calculate the average rate of return:
Average Rate of Return = ($350,000 / $10,000)^(1 / (67 - 21)) - 1
To solve the equation for the average rate of return:
Average Rate of Return = ($350,000 / $10,000)^(1 / 46) - 1
We can simplify the equation:
Average Rate of Return = 35^(1 / 46) - 1
Using a calculator, we can evaluate the expression:
Average Rate of Return ≈ 0.0559
Therefore, the average rate of return on the investment is approximately 5.59%.

Why is −318 a rational number? A. It is rational because all negative numbers are rational. B. It is rational because all integers are rational. C. It is rational because it can be expressed as a repeating decimal. D. It is rational because it can be expressed as a terminating decimal.
Answers
Answer:
The correct answer is the option B: It is rational because all integers are rational.
Step-by-step explanation:
To begin with, a rational number is the one that can be expressed as a fraction of two integers and that implicates all integers, both positives and negatives. Moreover, there are some rational numbers that can be expressed as well as a repeating number and others that can be expressed as a terminating number and all that will depend on the last number that the division will cause. So to sum up, -318 is a rational number because it is an integer and all of them can be divided and expressed as a fraction of two integers.

2. sample size is smaller than 5% of the population size.
3. sample size is greater than 5% of the sample size.
4. None of these choices.
Answers
The finite population correction factor is used in computing the standard error of the sample mean when the sample size is smaller than 5% of the population size.
The finite population correction factor is a adjustment made to the standard error of the sample mean when the sample is taken from a finite population, rather than an infinite population.
It accounts for the fact that sampling without replacement affects the variability of the sample mean.
When the sample size is relatively large compared to the population size (more than half), the effect of sampling without replacement becomes negligible, and the finite population correction factor is not necessary.
In this case, the standard error of the sample mean can be estimated using the formula for sampling with replacement.
On the other hand, when the sample size is small relative to the population size (less than 5%), the effect of sampling without replacement becomes more pronounced, and the finite population correction factor should be applied.
This correction adjusts the standard error to account for the finite population size and provides a more accurate estimate of the variability of the sample mean.
Therefore, the correct answer is option 2: the finite population correction factor is used when the sample size is smaller than 5% of the population size.

In the triangle below, with right angle R, suppose that m is Angle Q=(5x-13) and m is Angle S=(4x-5) Find the degree measure of each angle in the triangle.
Answers
Answer:
Degree measure of each angle is 90⁰, 47⁰ and 43⁰
Step-by-step explanation:
since the triangle is right angled, we assume that Q and S are the other angles of this triangle R
Thus using the concept that angles inside a triangle add up to 180⁰ and we already have one angle as 90⁰( since the triangle is right angled). we therefore know that Q + S = 90⁰
5x - 13 + 4x - 5 = 90⁰
9x = 108
x = 12
We now replace x in Q and S to get the angles
Q = 5(12) -13
= 47⁰
S = 4(12) - 5
= 43⁰
from Austin to Dallas is about 200 miles. How far apart will these cities appear on a map with the scale of ____ 1 in/50 mi ?
Answers
Answer:
on a map with a scale of 1 inch to 50 miles, Austin and Dallas will appear approximately 10000 inches apart. This is equivalent to approximately 833 feet or 254 meters.
Step-by-step explanation:
To determine the distance between Austin and Dallas on a map with a scale of 1 inch to 50 miles, you can use the formula:
distance on map = (distance in real life) / (scale)
Plugging in the values for the distance between Austin and Dallas (200 miles) and the scale (1 inch to 50 miles), you get:
distance on map = 200 miles / (1 inch / 50 miles)
distance on map = 200 miles / (1/50) inches
distance on map = 200 miles / 0.02 inches
distance on map = 10000 inches
So, on a map with a scale of 1 inch to 50 miles, Austin and Dallas will appear approximately 10000 inches apart. This is equivalent to approximately 833 feet or 254 meters.

The probability of selecting a boy is 2/3, and the events of being a boy and preferring indoor recess are independent.
What conclusions can be drawn based on the given data regarding the probability of selecting a boy and the probability of a student preferring indoor recess?Based on the given data, we can draw several conclusions. First, the total number of students surveyed is 240, with 160 of them being boys and 80 being girls.
This indicates that the sample consists of more boys than girls. The probability of selecting a boy from the surveyed students can be calculated by dividing the number of boys by the total number of students, resulting in 160/240 or 2/3, approximately 0.67.
The data shows that the total number of students who prefer indoor recess is 96.
This means that out of the surveyed students, 96 of them expressed a preference for indoor recess.
To determine the probability of any student preferring indoor recess, we divide this number by the total number of students, yielding 96/240 or 2/5, approximately 0.4.
Within the group of students who prefer indoor recess, 64 of them are boys.7.
