A coffee shop sells assorted types of coffees, and blends them into their "signature blends". Columbian sells for $3.40 per pound, and Kona sells for $6.80 per pound. A customer pays $19.55 for 3 pounds of a blend. How much of each type of coffee goes into the blend?

Answer: 3x-4

Step-by-step explanation:

If jennifer is x, and Chelsea bought 3 times more than her

then she bought 3x

but since shes giving 4 away to her teacher you subtract 4 from 3x

so the answer is 3x-4

Jennifer bought x books, so let b represent books.

Chelsea bought 3 times more books than Jennifer, so we write b x 3.

She gave 4 books to her teacher, so we write - 4.

The final answer is b x 3 - 4. Hope this helps!

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.

Answer:

This is d because if you plug the equations into Desmos it tells you the answer

Step-by-step explanation:

The measurement that is closer to the circumference of the circle in feet is 23.8 ft.

A circle's circumference is determined by the formula C = πd, where C is the circumference and d is the diameter of the circle.

Substituting the given value of the diameter, we get:C = π × 7.6

The value of π is approximately 3.14.C = 3.14 × 7.6C = 23.8

Therefore, the circumference of the circle in feet is 23.8 ft.

The work done when lifting the load vertically through 10 m is 4900 N·m.

The work done when lifting a load vertically can be calculated using the formula:

Work = Force × Distance

In this case, the force can be determined using the formula:

Force = Mass × Acceleration

Given that the load is 50 kg and the acceleration due to gravity is 9.8 m/s², we can calculate the force as:

Force = 50 kg × 9.8 m/s² = 490 N

The distance through which the load is lifted is 10 m. Substituting the values into the work formula, we get:

Work = 490 N × 10 m = 4900 N·m

Therefore, the work done when lifting the load vertically through 10 m is 4900 N·m.

In the explanation, we use the concept of work, which is defined as the product of force and distance, to calculate the work done when lifting a load vertically. The force is determined using the mass of the load and the acceleration due to gravity. By substituting the values into the work formula, we find that the work done is equal to 4900 N·m.

Answer:

\(\frac{1}{4}\)

Step-by-step explanation:

Given expression:

         3(-4x + 5) = 12

To solve for x;

  Use the distributive property to open the parentheses;

     3(-4x) + 3(5) = 12

      -12x + 15 = 12

 then, add -15 to both sides;

    -12x + 15 + (-15) = 12 + (-15)

            -12x  = -3

  divide both sides by -12;

        \(\frac{-12x}{-12}\)   = \(\frac{-3}{-12}\)

           x  = \(\frac{1}{4}\)

Answer: 26 minutes

Step-by-step explanation:

Assume that the total time spent in the morning which includes getting dressed, eating breakfast, making her bed, and driving to work is x.

Time getting dressed = ¹/₃x

Eating breakfast = 10 mins

Making bed = 5 mins

¹/₃x + 10 + 5 = 35 ½

¹/₃x + 15 = 35 ½

¹/₃x = 35 ½ - 15

¹/₃x = 20 ½

x = 20 ½ / ¹/₃

= 61.5 minutes

Total morning routine is is 61.5 mins

Time taken to drive to work is;

= 61.5 - 35 ½

= 26 minutes

a. The binomial probability distribution table is: x P(x) 0 0.4415 1 0.4215 2 0.1209 3 0.0159 4 0.0009 5 0.0000. b. The mean of the binomial distribution is 0.7 and c. the standard deviation of the binomial distribution is 0.887.

a. To create a binomial probability distribution table, we need to identify the values of n, p, and x.

n = 5 (since we are taking a sample of 5 students)

p = 0.14 (the probability of a student being first-generation)

x = 0, 1, 2, 3, 4, 5 (the number of first-generation students in the sample)

Using the formula for the probability mass function of a binomial distribution, P(x) = nCx * p^x * (1-p)^(n-x), we can calculate the probabilities for each value of x:

x P(x)

0 0.4415

1 0.4215

2 0.1209

3 0.0159

4 0.0009

5 0.0000

So, the binomial probability distribution table is:

x P(x)

0 0.4415

1 0.4215

2 0.1209

3 0.0159

4 0.0009

5 0.0000

b. The mean of a binomial distribution is given by the formula:

μ = n * p

Substituting the values, we get:

μ = 5 * 0.14 = 0.7

So, the mean of the binomial distribution is 0.7.

c. The standard deviation of a binomial distribution is given by the formula:

σ = sqrt(n * p * (1-p))

Substituting the values, we get:

σ = sqrt(5 * 0.14 * (1-0.14)) = 0.887

So, the standard deviation of the binomial distribution is 0.887

Indian River State Collge has stated in the 2019-2020 academic year 14% of its students were first-generation college students.

Suppose you take a random sample of 5 IRSC students and ask if they are first-generation college students or not, counting the number of first-generation students. Use this experiment to answer the following questions. Round solutions to four decimal places, if necessary.

a. Create a binomial probability distribution (table) for this experiment.

b. Calculate the mean of the binomial distribution.

c. Calculate the standard deviation of this binomial distribution.

Answer:

So, if 3 points were added to every score in the population, the new mean would be the old mean plus 3, and the new standard deviation would be the same as the old standard deviation.

Given,

3 points were added to every score in the population,

Adding a constant value to every score in a population will not change the standard deviation of the population, only the mean will change.

If we add 3 to every score in the population, the new mean will be the old mean plus 3. Let's say the old mean is μ and the old standard deviation is σ. Then the new mean will be μ + 3, and the new standard deviation will still be σ.

So, if 3 points were added to every score in the population, the new mean would be the old mean plus 3, and the new standard deviation would be the same as the old standard deviation.
