The product is less than 67,124 because the number 50,343 is less that the number 67,124.

The product is greater than 12,400 because the number 14,800 is greater than 12,400.

What is product?

A mathematical expression that specifies the objects to be multiplied, known as a factor, produces a product. For instance, the product of x and is c dot, and the product of 6 and 5 is 30.

First to multiply 67124 x 3/4

Here 67124 x 3 = 201372

⇒201372/4 = 50343

Hence, the product is less than 67,124 because the number 50,343 is less that the number 67,124.

Now to multiply 12,400 x 1 1/5

First to convert [tex]1\frac{1}{5}[/tex] into a fraction.

[tex]1\frac{1}{5} = \frac{5+1}{5} = \frac{6}{5}[/tex]

Now,

12,400 x 6/5 = 74,400/5 = 14800

Hence, the product is greater than 12,400 because the number 14,800 is greater than 12,400.

The cost of one calzone given the information in the table is $8.75 (first option).

The first step is to form a system of equation to represent the information in the question:

16p + 12c = 269 equation 1

20p + 8c = 275 equation 2

Where:

p =cost of pizzas bought

c = cost of calzones bought

The elimination method would be used to determine the cost of one calzone.

Multiply equation 1 by 5 and equation 2 by 4

80p + 60c = 1345 equation 3

80p + 32c = 1100 equation 4

Subtract equation 4 from equation 3

28c = 245

Divide both sides of the equation by 28

c = 245 / 28

Answer:  B. 278%

Step-by-step explanation:

The area of the circle formula is area = pi times r^2

Let's find the area of Circle X.

3.14 times 5^2 = 78.5

Let's find the area of Circle Y

3.14 times 3^2 = 28.26

Now take 78.5 divided by 28.26, then times 100% = 277.7% or ground up to 278%

So the answer is B. 278%

By using the formula of standard deviation, it can be calculated that

Standard deviation = 2.52

What is standard deviation?

At first it is important to know about variance.

Variance is the sum of the square of deviation from mean divided by the number of observations

Square root of variance gives standard deviation.

Here the data set is

3, 5, 6, 6, 9, 1

Mean = [tex]\frac{3 + 5 + 6 + 6 + 9 + 1}{6} = \frac{30}{6}[/tex] = 5

Variance = [tex]\frac{(3 - 5)^2 + (5 - 5)^2+(6 - 5)^2 + (6 - 5)^2 + (9 - 5)^2 + (1 - 5)^2}{6}[/tex]

                = [tex]\frac{4 + 0 +1+1+16+16}{6}[/tex]

                = [tex]\frac{38}{6}[/tex]

The equivalent expression is 2.3 raised to the fifteenth power divided by 0.9 raised to the twelfth power.

What analogous expressions are there?

Expressions that perform the same operations but differ in appearance are said to be equivalent.

There is the phrase;

{ (2. 3)^5/ (0. 9)^4 }^3

multiply by the denominator's inverse power.

(2. 3^5 × 0. 9^-4)^3

The system of equation to calculate the number of apples and oranges is given by x + y = 15 and 0.5x + 0.65y = 9 .

The number of apples is x and the number of oranges is y .

Total number of fruits bought is 15.

Hence we can write the equation for the number of fruits as:

x + y = 15

This is our first equation of the system.

Now each apple costs $ 0.5 , cost of x apples = 0.5x

Now each orange costs $0.65 , cost of y apples = 0.65y

Total cost is 9 apples.

Hence total cost can be represented by 0.5x + 0.65y = 9

Therefore the system of equations to represent the above situation is given by:

x + y = 15

0.5x + 0.65y = 9 .

A system of equations, often known as a set of simultaneous equations or an equation system, is a finite type of linear problem for which common solutions have been identified.

System utilization is the action of using something, i.e., making practical and effective use of it. Put simply; the term refers to the use of something or the process of using it effectively. In the supply chain industry, utilization may also refer to the percentage of available time that a machine, device, warehouse, or employee is actively is working.

We can also use the term for a fraction of the available time that a system is operating.

In a warehouse, space is essential, so warehouse space utilization measures the efficiency with which the warehouse uses its inventory storage capacity. Low values for this KPI may suggest that the warehouse is too large, inventory is being stored in improper places, demand forecasting is not accurate or that inventory replenishment processes are slow.

given that:

a single-bay car wash with a poission arrival rate and an exponential service time has cars arriving at an average of 8 minutes apart with an average service time of 4 minutes

Simple interest is calculated based on a loan's principal or the initial deposit into a savings account. Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay further interest on the interest that has already accrued.

The fact that

The equation for simple interest is:

A = P(1+rt)

where

The final investment value is A.

P is the initial investment's principal.

The interest rate is r.

There are t time periods.

We have a problem with this.

t = ?

P = $2100

A = $9400

r = 6% = 6/100 = 0.06

In the formula above, substitute

9400 = 2100 (1+t[0.06])

There is no exact answer to this question as it depends on the complexity of the puzzle. Generally speaking, a puzzle with a diameter of 20 inches would contain between 1000 and 2000 pieces.

Step-by-step explanation:

The slope of the two points, (1,3) and (-3,5) is -1/2 and can be calculated by the point-slope formula.

We know that the slope is a change in y divided by a change in x or we can say  "rise over run". The point-slope formula is given by-

(y2-y1) = m (x2-x1) ........where m is the slope.

Hence, we can manipulate it into m= (y2-y1) /(x2-x1) to find the slope of the given points.

let (1,3) = (x1,y1)

and (-3,5) = (x2,y2)

substituting these coordinates in the equation of the slope we get,

slope= (5-3) /(-3-1)

         = 2/-4

         = -1/2

Hence, the slope of the given two points (1,3) and (-3,5) is -1/2.

In order to determine the critical values for an independent-samples T-test, the following information needs to be known:

The critical values for an independent-samples t test are used to determine if the differences between two samples are statistically significant. In order to calculate the critical values, the size of the sample (n), the significance level (alpha), the degrees of freedom (df), and the type of t-test (one-tailed or two-tailed) must be known. The degrees of freedom are equal to the number of observations in the sample minus

The size of the sample is the total number of observations in the two samples. The significance level is the probability of making a type-I error (rejecting the null hypothesis when it is true). Finally, the type of t-test is used to determine if the test is one-tailed (testing for a difference in one direction) or two-tailed (testing for a difference in both directions). Once all of this information is known, the critical values can be calculated to determine if the differences between the two samples are statistically significant.

The values of a, b and c if the root x = 3 ± 2i  are 1, -6 and 13

From the question, we have the following parameters that can be used in our computation:

x=3\pm2ix=3±2i

y = ax2 +bx+c

Rewrite the above expressions properly

So, we have the following representation

x = 3 ± 2i

y = ax² + bx + c

This means that

x₁ = 3 + 2i

x₂ = 3 - 2i

The quadratic equation is then calculated as

y = (x - x₁) * (x - x₂)

Substitute the known values in the above equation, so, we have the following representation

y = (x - (3 + 2i)) * (x - (3 - 2i))

This gives

y = ((x - 3) + 2i) * ((x - 3 - 2i)

Apply the difference of two squares

y = (x - 3)² + 4
