The least positive integer that will be divisible by both 15 and 35 will be 105.

The given integers are 15 and 35.
As we know that the least positive integer will be divisible by both 15 and 35 will be LCM ( least common factor) of 15 and 35.
The least common multiple of LCM of two integers is the common multiple of two numbers such that it is the least among all common multiples.
For example, LCM of 3 and 5 will be 15 because among all common multiples of 3 and 5, 15 will be least common multiple.
For LCM of 15 and 35, let's write multiples of both the numbers.
Multiples of 15 = 15,30,45,60,75,90,105,120,135,150,165,180,195,210,....
Multiples of 35= 35,70,105,140,175,210,...
We can see that 105 and 210 are two common multiples out of which 105 is the least multiple.

Answer:

Step-by-step explanation:

We can solve this problem by using a system of linear equations. Let's call a and b the two numbers we are looking for. We know that a times b equals 10000 and that a plus b equals some other number x. We can write these two equations as follows:

a * b = 10000

a + b = x

We can solve for a in terms of b by rearranging the first equation:

a = 10000 / b

Substituting this expression for a into the second equation gives:

10000 / b + b = x

Multiplying both sides by b gives:

10000 + b^2 = bx

Rearranging this equation gives:

b^2 - xb + 10000 = 0

This is a quadratic equation in terms of b. We can solve for b using the quadratic formula:

b = (x ± sqrt(x^2 - 4 * 10000)) / 2

Since neither a nor b are divisible by 10, we know that both a and b must be multiples of 5. Therefore, we can assume that x is also divisible by 5.

Let's try an example where x equals 5005:

b = (5005 ± sqrt(5005^2 - 4 * 10000)) / 2

b ≈ (5005 ± sqrt(25000025 - 40000)) / 2

b ≈ (5005 ± sqrt(24960025)) / 2

b ≈ (5005 ± 4996) / 2

So we have two possible values for b:

b ≈ (5005 + 4996) / 2 = 5000.5

b ≈ (5005 - 4996) / 2 = 4.5

Since neither a nor b are divisible by 10, we know that the correct value for b is:

b ≈ (5005 - 4996) / 2 = 4.5

Substituting this value for b into the first equation gives:

a ≈ 2222.22

Therefore, a plus b equals approximately 2226.72.

To calculate Randy Burgarner's social security tax withholding, we first need to determine his gross monthly salary. Randy's total earnings to date are $14,400.00. Since we know that his gross monthly salary is $3,600.00, we can divide the total earnings by the number of months worked.

Social security tax withholding is $223.20 and medicare tax withholding for Randy Burgarner is $52.20. The solution to this problem is explained as under.

Total earnings to date: $14,400.00
Gross monthly salary: $3,600.00
Months worked = Total earnings to date ÷ Gross monthly salary
Months worked = $14,400.00 ÷ $3,600.00
Months worked = 4
Randy has worked for 4 months. Now we can calculate the social security tax withholding for this month.

The social security tax rate is 6.2% of the gross salary. To find the social security tax withholding, we multiply the gross monthly salary by the social security tax rate.
Social Security tax rate: 6.2%
Gross monthly salary: $3,600.00
Social Security tax withholding = Gross monthly salary × Social Security tax rate
Social security tax withholding = $3,600.00 × 6.2%
Social security tax withholding = $223.20
Therefore, this month's social security tax withholding for Randy Burgarner is $223.20.

Now let's calculate the Medicare tax withholding for this month.
The Medicare tax rate is 1.45% of the gross salary. To find the Medicare tax withholding, we multiply the gross monthly salary by the Medicare tax rate.
Medicare tax rate: 1.45%
Gross monthly salary: $3,600.00
Medicare tax withholding = Gross monthly salary × Medicare tax rate
Medicare tax withholding = $3,600.00 × 1.45%
Medicare tax withholding = $52.20

Therefore, this month's Medicare tax withholding for Randy Burgarner is $52.20.

The sample size increases, the probability of obtaining a sample mean less than 3500 decreases. The mean of the sample mean distribution is equal to the population mean, which is 7500.

a) The probability that, on a single test, x is less than 3500 can be calculated using the standard normal distribution. We need to standardize the value using the z-score formula: z = (x - μ) / σ. Substituting the given values, we get z = (3500 - 7500) / 1750 ≈ -2.286.

Using a standard normal distribution table or a calculator, we can find the probability associated with a z-score of -2.286. The probability is approximately 0.0116, or 1.16%. Therefore, there is a 1.16% chance that a single test result will be less than 3500, indicating leukopenia.

(b) When the doctor uses the average x (sample mean) for two tests taken about a week apart, the probability distribution of x (sample mean) follows a normal distribution. The mean of the sample mean distribution is equal to the population mean, which is 7500. The standard deviation of the sample mean distribution is equal to the population standard deviation divided by the square root of the sample size. In this case, the sample size is 2.

The probability distribution of x (sample mean) < 3500 can be calculated by standardizing the value using the z-score formula and then finding the corresponding probability from the standard normal distribution table or a calculator. With two tests, the probability distribution will be narrower compared to a single test. The exact probability depends on the specific value of the sample mean and the standard deviation of the sample mean distribution.

(c) When considering three tests taken a week apart, the process is similar to part (b). The mean of the sample mean distribution remains the same at 7500, but the standard deviation of the sample mean distribution is now divided by the square root of 3, since the sample size is 3. As the sample size increases, the standard deviation of the sample mean distribution decreases, resulting in a narrower distribution.

The probability distribution of x (sample mean) < 3500 can be calculated using the z-score formula and finding the corresponding probability from the standard normal distribution table or a calculator. With three tests, the probability distribution will be even narrower compared to two tests.

In summary, as the sample size increases, the probability of obtaining a sample mean less than 3500 decreases. With more tests, we can have greater confidence in the accuracy of the sample mean and draw stronger conclusions about the individual's condition. If a person had a sample mean less than 3500 based on three tests, it would indicate a higher level of certainty about the presence of leukopenia, potentially leading to further investigation or treatment options.

Step-by-step explanation:

The probability of getting exactly 417 girls in 811 births is approximately 0.0668.

The probability of getting 417 or more girls in 811 births is approximately 0.1349.

a. The probability of getting exactly 417 girls in 811 births is not 1. The correct probability can be calculated using the binomial probability formula:

P(X = k) = (n choose k) * p^k * (1-p)^(n-k)

where n is the total number of births, k is the number of girls, p is the probability of a girl birth (assumed to be 0.5 for simplicity), and "n choose k" denotes the binomial coefficient, which is calculated as:

(n choose k) = n! / (k! * (n-k)!)

Plugging in the values, we have:

P(X = 417) = (811 choose 417) * 0.5^417 * 0.5^(811-417)

Using a calculator or software, we can simplify and evaluate this expression to find:

P(X = 417) ≈ 0.0668

So the probability of getting exactly 417 girls in 811 births is approximately 0.0668.

b. To find the probability of getting 417 or more girls in 811 births, we need to calculate the cumulative probability from 417 to 811:

P(X ≥ 417) = P(X = 417) + P(X = 418) + ... + P(X = 811)

We can use software or a calculator to calculate this sum, or we can use the complement rule:

P(X ≥ 417) = 1 - P(X < 417)

To calculate P(X < 417), we can use the cumulative distribution function (CDF) of the binomial distribution:

P(X < 417) = sum(i=0 to 416) (811 choose i) * 0.5^i * 0.5^(811-i)

Again, using software or a calculator, we can evaluate this expression to find:

P(X < 417) ≈ 0.8651

So the probability of getting 417 or more girls in 811 births is:

P(X ≥ 417) = 1 - P(X < 417) ≈ 1 - 0.8651 ≈ 0.1349

Rounding to four decimal places, the probability of getting 417 or more girls in 811 births is approximately 0.1349.

Answer:

300 nickels

Step-by-step explanation:

Reading the question, someone has 435 nickels and dimes.

The total is $28.50.

You're trying to find how many nickels he has.

All you need to do is set up a system of equations.

I'm going to use x as the number of nickels and y as the number of dimes.

Based on the question, you can say that

x + y = 435

(the number of nickels and dimes have t equal 435)

and 0.05x + 0.1y = $28.50

(nickels are 5 cents and dimes are 10 cents)

You want to solve for x, the number of nickels.

You can manipulate the first equation by subtracting x on both sides.

After you do that, you will get y = 435 - x. Now, you can substitute this equation into the second one.

First, you can distribute the 0.1.

0.05x  + 0.1(435 - x) = 28.50

Then, you can put the two x's together.

0.05x + 43.5 -0.1x = 28.50

Next, you can subtract 43.5 on both sides to isolate x.

-0.05x + 43.5 = 28.50

Finally, you can divide on both sides to get x, which is the number of nickels.

-0.05x = - 15

x = 300 nickels

Answer:

Ben has 19 marbles

Step-by-step explanation:

First taking that josh and ricks ratio is 1:2, this would set up in an equation as \(2j = r\) and with ben having 15 less than rick, his formula would be \(r = b + 15\) as well as the total of all the boys marbles together being this \(j+r+b=70\)

Now we put all of these equations into a set to answer them.

\(2j = r\\ r = b + 15\\j+r+b=70\)

First we solve for j

\(2j = r\\ j=\frac{1}{2} r\)

Then substitute j

\(j+r+b=70\\ \frac{1}{2}r+r+b=70\\ 2b+3r=140\)

Then simplify and multiply by 2 to even out

\(r = b + 15\\ -b+r=15\\2b+3r=140\)

Now eliminate the b variable and combine equations

\(2b+3r=140\\-2b+2r=30\)

\(5r=170\)

Now divide and solve for r

\(5r=170\\r=34\)

Now we know Rick has 34 marbles of the 70 marbles, so we can substitute his number back into the original equation

\(-b+34=15\\b=19\)

Now we know Ben has 19 marbles of the remaining 36, and can substitute his number as well

\(j=\frac{1}{2}(34)\\j=17\)

And now we know how much everyone has, to check we rewrite all the equations with their respective numbers

\(11+34+19=70\\2(17)=34\\34=19+15\)

\(70=70\\34=34\\34=34\)

Which means the ordered pairing of (b, j, r) is (19, 17, 34)

We have,

To estimate the number of students in the class, we can assume that the highest number observed in the sample (in this case, 26) is likely to be close to the actual number of students.

This assumption is based on the idea that if we have randomly called out a few students, there is a higher chance of getting a higher number if the total number of students is larger.

Therefore, by taking the maximum value observed in the sample as an estimate, we are essentially assuming that the highest number corresponds to the total number of students in the class.

In this case, since the highest number observed is 26, we can estimate that there are approximately 26 students in the class.
