Answer:

252 m^2

Step-by-step explanation:

The equation for surface area in a rectangular prism is SA = 2 (lh +wh + lw ).

So when we plug in the numbers inti the equation we do SA = 2(12×3 + 6×3 + 12×6)

FOLLOW P.E.M.D.A.S (parentheses, exponents, multiplication, division, addition, subtraction)

we get SA = 2(36 + 18 + 72)

then we multiply 2, by each of the numbers.

SA = (72 + 36 + 144)

Add them together and you get

SA = 252

There is zero or no degree of freedom in  the mean of the differences in a paired t-test.

For the paired t-test, we need two variables. One variable defines the pairs for the observations. The second variable is a measurement. Sometimes, we already have the paired differences for the measurement variable. Other times, we have separate variables for “before” and “after” measurements  for each pair and need to calculate the differences.

We also have an idea, or hypothesis, that the differences between pairs is zero. It is also known as the dependent samples t-test, the paired-difference t-test, the matched pairs t-test and the repeated-samples t-test.

An apple would cost $0.6 while a plum would cost $0.25.

The total cost of buying 2 plums and 2 apples will be $1.7

Cost is the value of money that has been used or exchanged up to produce something or deliver a service. Money is an input that is gone in order to acquire something.

If 6 plums sell for $1.50, then;

1 plum will be (1.50/6) = $0.25

Also, if 5 apples cost $3.00, then;

1 apple will be (3/5) = $0.6

Therefore 2 apples will cost: 2 x $0.6 = $1.2

and 2 plums will cost: 2 x $0.25 = $0.5

Total cost for 2 apples and 2 plums will be = $1.2 + $0.5

The midpoint of CT is located at (b) (1, -1)

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

C = (-7, -9)

T = (9, 7)

The midpoint of the line CT can then be calculated as

Midpoint = 1/2 * (C + T)

So, we have the following representation

Midpoint = 1/2 * (-7 + 9, -9 + 7)

Evaluate

Midpoint = 1/2 * (2, -2)

So, we have

Midpoint = (1, -1)

The equation of the red graph is x² + 2

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. Mathematical algebraic equations typically have one or more variables.

Since the function in the graph is headed upward , we know the portion of  x²  is positive . And since the highest point of the red line on the y-axis is 2, we can conclude the function represented by the red line is

We can not solve the system of equation because the equations represent two parallel lines (they have no points in common).

Given that,

The system of equations are -3x+y=6 and 6x-2y=25

We must resolve the equation system.

We know that,

Take the system of equation

-3x+y=6 ------->equation(1)

6x-2y=25 ------>equation(2)

We multiply equation(1) by -2 and subtracting them

-2(-3x+y=6)

6x-2y=-12

6x-2y=25

The total deduction from Dean's paycheck for Social Security and Medicare is $24.11.

What is a percentage?

A percentage is a way of expressing a number as a fraction of 100. It is often used to express a proportion or a ratio, and is denoted by the symbol "%".

To find the deduction from Dean's paycheck for Social Security and Medicare, we need to calculate the total amount of tax that he owes based on his gross pay.

First, we can calculate the Social Security tax by multiplying Dean's gross pay by the tax rate:

Social Security tax = $315.75 x 6.2% = $19.54

Next, we can calculate the Medicare tax by multiplying Dean's gross pay by the tax rate:

Medicare tax = $315.75 x 1.45% = $4.57

To find the total deduction from Dean's paycheck, we can add the two amounts:

Total deduction = $19.54 + $4.57 = $24.11

Hence, the total deduction from Dean's paycheck for Social Security and Medicare is $24.11.
