If the circumference of a circle is 201 centimeters what is the radius of the circle (to the nearest whole number)? Use 3.14 for pi
A) 32 centimeters
B) 128 centimeters
C) none
D) 16 centimeters
E) 64 centimeters
Final answer:
The radius of a circle with a circumference of 201 centimeters is approximately 32 centimeters, found by dividing the circumference by 2 times pi (π), using 3.14 as the value of pi. The correct answer is A) 32 centimeters.
Explanation:
The question asks us to find the radius of a circle when its circumference is given to be 201 centimeters. We use the circumference formula of a circle, which is C = 2πr, where C stands for circumference, π (pi) is a constant approximately equal to 3.14, and r represents the radius of the circle.
To find the radius, we rearrange this formula to solve for r:
Divide both sides of the equation by 2π to isolate r.
Plug in the given circumference value, C = 201 cm, and the approximate value of pi, π = 3.14, into the rearranged formula.
So the calculation would be r = C / (2π) = 201 / (2 * 3.14) = 201 / 6.28. When we compute this, we get r ≈ 32 centimeters to the nearest whole number.
Therefore, the correct answer is A) 32 centimeters.

There are 10 apples in the fridge and 2 of them are bad. if you grab 3 apples, what is the expected number of bad apples
The expected number of bad apples is [tex]\( \frac{2}{10} \times 3 = 0.6 \) bad apples.[/tex]
The expected number of bad apples when grabbing 3 apples from a pool of 10, of which 2 are bad, can be calculated using probability.
To calculate this, follow these steps:
1. Calculate the probability of picking a bad apple:
The probability of picking a bad apple is the ratio of the number of bad apples to the total number of apples. In this case, it's [tex]\( \frac{2}{10} = 0.2 \) or 20%.[/tex]
2. Multiply the probability by the number of apples picked:
Multiply the probability of picking a bad apple by the number of apples you're picking.
[tex]\( 0.2 \times 3 = 0.6 \)[/tex]
When you pick 3 apples randomly from a pool of 10, you're essentially conducting a sampling experiment. The probability of picking a bad apple on any given pick is[tex]\( \frac{2}{10} \),[/tex] which simplifies to 0.2 or 20%.
Since you're picking 3 apples, you multiply the probability of picking a bad apple by 3 to find the expected number of bad apples. This is because in expectation, you would expect that proportion of bad apples in your sample. So, [tex]\( 0.2 \times 3 = 0.6 \)[/tex], which means you would expect to pick approximately 0.6 bad apples when picking 3 from the pool of 10, assuming the picking is random.
So, the final answer is that you would expect about 0.6 bad apples when picking 3 apples from a pool of 10, of which 2 are bad.

The radius r of a circle is increasing at a rate of 8 centimeters per minute. find the rate of change of the area when r = 39 centimeters
The rate of change of the area of the circle when the radius is 39 centimeters is 1976π cm²/min. This uses the concept of related rates in calculus and the area formula A = πr².
Explanation:The problem deals with the concept of related rates in calculus. In this problem, we're looking at how the rate of change of the radius of a circle impacts the rate of change of the area of the circle. The formula for the area of a circle is A = πr².
Differentiating both sides with respect to time(t) gives dA/dt = 2πr(dr/dt). In this case, dr/dt (the rate of change of the radius) is given as 8 cm/min. To find dA/dt (the rate of change of the area) when r = 39 cm, we substitute these values into the differentiated equation: dA/dt = 2π(39cm)(8 cm/min) = 1976π cm²/min
So, the rate of change of the area when r = 39 centimeters is 1976π cm²/min. As the radius increases, the area of the circle increases at a rate directly proportional to the radius.

Erving Spencer makes a salary of $24,000 per year and he is paid biweekly. If his employer puts 6.5% into his pension, how much goes into the pension every paycheck? $15.60 $60 $65 $156
Erving Spencer contributes $60 to his pension every paycheck, with a biweekly pay schedule on a $24,000 yearly salary. Regarding the retirement funds, after 30 years, Alexx would have more money than Spenser because Alexx's investment grows at an unimpeded 5% annually, while Spenser's grows at 4.75% annually after fees.
Explanation:Firstly, let's address the question about Erving Spencer's pension contributions per paycheck. Erving Spencer makes $24,000 a year and is paid biweekly, which means there are 26 paychecks in a year. To calculate how much goes into the pension every paycheck, we apply the percentage of the pension contribution to each paycheck:
Annual salary: $24,000Contributions per paycheck: ($24,000 / 26) * 6.5%Now, let's perform the calculations:
Contribution per paycheck = ($24,000 / 26) * 0.065
= $923.08 * 0.065
= $60
Therefore, $60 goes into Erving Spencer's pension every paycheck.
Now, for the question about the retirement fund's administrative fee:
Alexx and Spenser each invest $5,000 in the same stock. Alexx's investment grows by 5% annually without any fees, while Spenser's grows by 4.75% annually after a 0.25% fee. After 30 years:
Alexx's investment: $5,000 * (1 + 0.05)^30Spenser's investment: $5,000 * (1 + 0.0475)^30We can calculate the final amounts and then find the difference between them, which would be how much more Alexx has than Spenser after 30 years.
Standard 6 sided die is weighted so that the probabilities of rolling 2,3,4,5 or 6 are equal and the probability of rolling 1 is three times the probability of rolling a 2. if the die is thrown twice, what is the probability that the sum of the numbers thrown will be 4
There are 6 sides of the die, let us say that side 1 is S1, side 2 is S2 and so on.
Assigning a value of 3 to S1, so the probabilities are:
Probability
S1 = 3 3/8
S2 = 1 1/8
S3 = 1 1/8
S4 = 1 1/8
S5 = 1 1/8
S6 = 1 1/8
total = 8
The combinations that the sum of the two rolls will be 4 are:
S1 and S3
S3 and S1
S2 and S2
So the total probability is:
P = (3/8) * (1/8) + (1/8) * (3/8) + (1/8) * (1/8)
P = 0.1094 = 10.94%
So there is about 0.1094 or 10.94% probability that the sum will be 4.

You have just arranged for a $1,640,000 mortgage to finance the purchase of a large tract of land. the mortgage has an apr of 6.4 percent, and it calls for monthly payments over the next 30 years. however, the loan has an eight-year balloon payment, meaning that the loan must be paid off then. how big will the balloon payment be?
The balloon payment is approximately $1,084,898.37.
To calculate the balloon payment, we first need to determine the remaining balance of the mortgage after the initial 22 years of payments (30 years total - 8 years).
Step 1: Calculate the monthly interest rate.
Monthly interest rate = Annual interest rate / 12
Monthly interest rate = 6.4% / 12 = 0.00533
Step 2: Calculate the number of payments made in 22 years.
Number of payments = 22 years * 12 months/year = 264 payments
Step 3: Use the formula for the remaining balance of a mortgage.
Remaining balance = [tex]P * [(1 + r)^n - (1 + r)^t] / [(1 + r)^n - 1][/tex]
Where:
P = principal amount of the loan
r = monthly interest rate
n = total number of payments
t = number of payments already made
Substitute the given values into the formula:
Remaining balance = $1,640,000 * [(1 + 0.00533)^360 - (1 + 0.00533)^264] / [(1 + 0.00533)^360 - 1]
Remaining balance = $1,084,898.37
The balloon payment is the remaining balance after 22 years. Therefore, the balloon payment is approximately $1,084,898.37.

Kevin and randy Muise have a jar containing 41 coins all of which are either quarters or nickels . The total value of coins in the jar is 7.45 how many of each type of coin do they have
To find the number of quarters and nickels, we can set up a system of equations using the total number of coins and the total value of the coins. Solving this system of equations, we find that Kevin and Randy have 27 quarters and 14 nickels.
Explanation:To solve this problem, we can set up a system of equations. Let's use the variables q (number of quarters) and n (number of nickels). We know that there are a total of 41 coins, so we can write the equation q + n = 41. We also know that the total value of the coins is $7.45, so we can write the equation 0.25q + 0.05n = 7.45.
Now we can solve this system of equations using substitution:
Isolate one variable in one of the equations. Let's isolate q in the first equation: q = 41 - n.Substitute this expression for q in the second equation: 0.25(41 - n) + 0.05n = 7.45.Simplify and solve for n: 10.25 - 0.25n + 0.05n = 7.45. Simplifying further, we get 0.20n = 2.80. Dividing by 0.20, we find that n = 14.Substitute this value of n back into the first equation to find q: q = 41 - 14 = 27.Therefore, Kevin and Randy have 27 quarters and 14 nickels in their jar.

And 1. if a person bought 1 share of google stock within the last year, what is the probability that the stock on that day closed at less than the mean for that year? hint: you do not want to calculate the mean to answer this one. the probability would be the same for any normal distribution.
The probability that the stock closed at less than the mean for that year is approximately 0.5, assuming a normal distribution.
1. In a normal distribution, the mean divides the distribution into two equal halves, with 50% of the data falling below the mean and 50% above it.
2. Therefore, the probability that a randomly chosen data point (in this case, the closing price of stock) is below the mean is 0.5 or 50%.
Now, let's dive into the step-by-step calculation to illustrate this:
1. Identify the Mean and Standard Deviation: While you mentioned not to calculate the mean, it's important to understand that for a normal distribution, the mean is at the center and separates the distribution into equal probabilities on either side. However, we do need to know the standard deviation, which measures the spread of data points around the mean. Let's assume the mean closing price for stock over the past year is $X, and the standard deviation is $Y.
2. Use the Standard Normal Distribution: Since we're dealing with a normal distribution, we can use the standard normal distribution to find probabilities. This distribution has a mean of 0 and a standard deviation of 1.
3. Standardize the Data: To work with the standard normal distribution, we need to standardize the data point we're interested in. Let's denote the closing price of stock on the chosen day as $Z. We standardize this value using the formula:
[tex]\[ Z = \frac{{Z - X}}{{Y}} \][/tex]
Here, ( Z ) is the standardized value.
4. Find the Probability: Once we have the standardized value ( Z ), we can look it up in a standard normal distribution table or use software/tools to find the probability that a randomly chosen value from a standard normal distribution is less than ( Z ). This probability will be the same as the probability that the stock closed at less than the mean for that year.
5. Conclusion: Based on the properties of a normal distribution, the probability that a randomly chosen data point (stock closing price) is below the mean is always 0.5 or 50%. This holds true regardless of the specific mean or standard deviation values for stock.
