Answer:

D

Step-by-step explanation:

x>10 is your answer. since theres no less than or greater or equal to c and B are automatically out. x>10 says x is greater then 10 so it is D

Its B, always remember to check if the dot is opened or closed on the line!!

The correct answer is (4x^3 - 8x^2 )

Solve by using Foil's Method

Multiply (x - 3)(4x^2)

Begin, by multiplying together, the first terms of binomial

= x * 4x^2 = 4x^3

Now, multiply the last term of binomial.

= -3 * 4x^2 = -12x^2

Sum up the partial products starting from the first to last product from the first to last product and collect it:

=(4x^3 - 8x^2 )

Now, Let us know

What is Foil's Method ?

FOIL a mathematical series of steps used to multiply two binomials.

By definition we have the meaning of FOIL is given by:

F: First

O: Outer

Deducted from her paycheck this week for Social Security is $31.13.Medicare is equal to $7.28.

Maria Wehstone, Gross weekly income = 502.16 and annual earnigs till date = 20,086.40

Deduction for this week for social security = 6.20% of 502.16$ = $31.13

Deduction for this week for Medicare = 1.45% of 502.16$ = $7.28

Social security is the safety net that a society offers to people and families to ensure that they have access to health care and to assure financial stability, particularly in circumstances of old age, unemployment, illness, invalidity, work injuries, maternity, or the death of a primary earner.

Based on their career earnings, Social Security replaces a portion of your pre-retirement income.

Step-by-step explanation:

Let x = number of rides.

Tony's cost: 4.5x + 25

Ride's cost: 5x + 18

Set the prices equal and solve for x.

5x + 18 = 4.5x + 25

Subtract 4.5x from both sides.

0.5x + 18 = 25

Subtract 18 from both sides.

0.5x = 7

Multiply both sides by 2.

x = 14

Using translation concepts, the coordinates of the image of the triangle are given as follows:

A'(-1,-4), B'(-2,0), C'(-3, -11).

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

The rule for a 90° counterclockwise rotation about the origin is given as follows:

The polynomial expression for the profit from making and selling x model kits is 28x - 500,000 - 0.00005 x² and the profit is 3400000.

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]

It is given that:

Suppose the cost in dollars of producing x model kits is given by the polynomial 500,000 + 2x and the revenue generated from sales is given by the polynomial 30x - 0.00005 x².

The profit = revenue - cost

The profit = (30x - 0.00005 x²) - (500,000 + 2x)

The profit = 30x - 0.00005 x² - 500,000 - 2x

The profit = 28x - 500,000 - 0.00005 x²

Plug x = 300,000 in the profit expression.

The profit = 3400000

Thus, the polynomial expression for the profit from making and selling x model kits is 28x - 500,000 - 0.00005 x² and the profit is 3400000.

Considering the definition of an equation and the way to solve it, the number of miles in a day at which the rental costs for Company A and Company B are the same is 200.

An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear.

The members of an equation are each of the expressions that appear on both sides of the equal sign.

The solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:

First, you define the variable "m" as the number of miles rented from a truck to a company in a day. You know that:

So the price of each company is:

If the rental costs for Company A and Company B are the same, the equation in this case is:

Price of company A= Price of company B

130 + 0.30m= 70 + 0.60m

Solving:

130 - 70= 0.60m - 0.30m

60= 0.30m

60÷0.30= m

200= m

In summary, the number of miles in a day at which the rental costs for Company A and Company B are the same is 200.

The total proportion of shirts between two prices is 0.9431, which is obtained using the knowledge of proportion and statistics.

What is proportion?

In mathematics, a proportion is defined as the comparison between two numerical quantities. If both possess the same nature, they are called directly proportional, or else called inversely proportional.

Calculation of the proportion based on the problem

The mean and standard deviation are given to be 45 and 5 respectively

Calculate standard normal variate using the formula, z = (x - 45) / 5

Taking x = 37, we get,

z1 = (37 - 45) / 5

= -1.6

Using the z table, we get the value, z1 = 0.0548

Now, taking x = 59.35, we get,

z2 = (59.35 - 45) / 5

= 2.87

Using the z table, we get the value, z2 = 0.9979

The proportion between two prices is given by z = z2 - z1

z = 0.9979 - 0.0548

= 0.9431

Hence, the proportion of shirts between the two prices is 0.9431.

FInding:

Let the shortest side of the triangular lot be 'x'.

Then, according to the question, one side of the triangular lot = 100 + x and other = 300 + x

As perimeter of a triangle = sum of all the sides,

=> 1300 = x + 100 + x + 300 + x

=> 1300 - 400 = 3x

=> 900 = 3x

The formula for calculating the probability of one success under certain conditions is:

x=0.4.

"The ratio of the number of favorable outcomes to the total number of outcomes is the standard mathematical definition of probability. Probability is never more than one, and it is never equal to that number."

Generally, the equation for Probability is  mathematically given as

According to the question,

Total number of trials n'=4

Number of successes r =1

p=0.35

q=1-0.35

q=0.65

Simply replace the value in order to calculate the appropriate probability.

[tex]\text { Probability } &={ }^4 C_1(0.35)^1(0.65)^{4-1} \\[/tex]

[tex]&=\frac{4 !}{(4-1) ! 1 !} \times \frac{35}{100} \times\left(\frac{65}{100}\right)^3 \\[/tex]

The claim that a researcher may infer a causal link between variables if one effects another is False.

If a change in one variable's level results in a change in the other variable, then there is a causal relationship between the two variables. Keep in mind that correlation does not always imply causation. Two variables may be linked together without one of them directly contributing to the other's observable behavior.

For instance,

the chart below illustrates the relationship between ice cream sales and temperature. Any business can utilize the concept of causality. As is clear from the graph, there is a correlation between warmer weather and increased sales.

A casual relationship between two variables only exists when one of the variables actually causes the other to exist, which does not appear to be the case here. Instead, since a change in one variable affects the other, this scenario can be thought of as a correlated relationship.
