Answer:

C

Step-by-step explanation:

There are two outcomes for the input of 1 in the value of x, which violates the standards of a function

For the single value of x, the value of y will be single. Then option C does not represent a function.

A statement, principle, or policy that creates the link between two variables is known as a function

We know that the value of x must be different.

For the single value of x, the value of y will be single.

Then option C does not represent a function.

Answer:

Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient. ...

Step 2: Subtract the second equation from the first.

Step 3: Solve this new equation for y.

Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x.

Step-by-step explanation:

Answer:

To solve a system of linear equations, we eliminate a variable from the equations by multiplying its coefficient with a suitable number so that they cancel out each other.

Then we are left with only one variable and we add/subtract them to get their value.

When we get the value of one variable, we can substitute it in either of the equations to find the value of the other variable.

Answer:

A = 30m + 35

Step-by-step explanation:

let A be the amount saved and m represent month

Note the difference in the amount saved is constant, that is

185 - 155 = 155 - 125 = 125 - 95 = 95 - 65 = 30

We can express this as

A = 30m + c

To find c use any pair from the table and substitute into the equation

using (3, 125) then

125 = (3 × 30) + c

125 = 90 + c ( subtract 90 from both sides )

c = 125 - 90 = 35, thus

A = 30m + 35 ← linear relationship

As a check

When m = 4, A should be 155

A = (4 × 30) + 35 = 120 + 35 = 155 ← correct

Linear function representing the table is

A(m) = 30m + 35

Answer:

c = 11/4

Step-by-step explanation:

One way of doing this is to let 2c = x.  Then our equation becomes

2x + x = 2x + 11/2, or x = 11/2.

But 11/2 = 2c.  Thus, c = 11/4

Answer:

The correct answer is third option

The sum of any number and its opposite is 0

Step-by-step explanation:

It is given an expression,

8.29 * (-5.62 + 5.62)/5.62

To find the correct reason

Here - 5.62 + 5.62 = 0

5.62 is opposite to - 5.62

because sum of a number and its opposite is 0.

Therefore the correct answer is third option.

The sum of any number and its opposite is 0

Answer:

The sum of any number and it's opposite is 0.

Step-by-step explanation:

Given expression is [tex]8.29\cdot\frac{-5.62+5.62}{5.62}[/tex]

Now we need to find the reason about why the given expression equals to 0.

If you look at the numerator carefully then you will find that numerator contains two terms -5.62 and +5.62 which are exactly same and opposite in sign. So they will cancel each other and give result 0.

After that we get only multiplication and division operation and we know that multiplication by 0 gives 0. that's why the final answer is 0.

So the correct choice is "The sum of any number and it's opposite is 0."

Answer:

They can't occur together because independent means by itself.

Step-by-step explanation:

The correct answer is D) A's occurrence cannot affect the probability of B's occurrence. This reflects the defining characteristic of independent events in probability, where the occurrence of one event does not influence the likelihood of another.

If events A and B are independent, then this means that the occurrence of event A does not affect the probability of event B occurring, and vice versa. This is a fundamental concept in the study of probability which distinguishes independent events from dependent or mutually exclusive events.

Among the options provided, the correct choice is D) A's occurrence cannot affect the probability of B's occurrence. Independent events have no influence on each other, meaning that if you know event A has happened, this knowledge does not change the likelihood of event B happening, and conditional probability does not apply here.

On the other hand, mutually exclusive events cannot occur together. If A and B were mutually exclusive, then the probability of both A and B occurring at the same time would be zero. This is not the case with independent events, where the probability of A and B occurring is simply the product of their individual probabilities if the events are occurring simultaneously.

Answer:

The value of x is 2 or -2.

Step-by-step explanation:

Consider the provided equation.

[tex]3x^2= 12[/tex]

We need to solve the above equation for x.

Divide 3 from both the sides.

[tex]\frac{3x^2}{3}=\frac{12}{3}[/tex]

[tex]x^2=4[/tex]

Square root both the sides.

[tex]x=\pm \sqrt{4}[/tex]

[tex]x=\pm 2[/tex]

Hence the value of x is 2 or -2.

The solution to the equation  [tex]3x^2 = 12[/tex]  is [tex]x = \pm2[/tex], which is [tex]x = 2[/tex] and [tex]x = -2.[/tex]

To solve the equation [tex]3x^2 = 12[/tex] algebraically:

Divide both sides of the equation by 3 to isolate the [tex]x^2[/tex] term:

[tex]\frac{3x^2}{3}=\frac{12}{3}[/tex]

[tex]x^2 = 4[/tex]

Take the square root of both sides to solve for x:

[tex]\sqrt{x^2}=\sqrt{4}[/tex]

[tex]x = \pm2[/tex]

Hence, the solutions to the equation [tex]3x^2 = 12[/tex] are [tex]x = 2[/tex] and [tex]x = -2.[/tex]

The 99% confidence interval for the mean number of jobs held by the retired men in the study is approximately 6.3 < μ < 8.1

To calculate the 99% confidence interval, we need the sample mean, the population standard deviation, the square root of the sample size, and the z-value associated to a 99% confidence. In this case, we know the following:

The confidence interval formula is given by the following equation:

x-bar ± z * (σ/√n)

Subbing the values into the equation, we get:

7.2 ± 2.57 * (2.1/√50)

The 99% confidence interval would therefore be approximately 6.3 < μ < 8.1

Solve for u

That means ------> isolate the variable u (dependent variable)

Subtract 6w both sides

[tex]-2u=9-6w[/tex]

Divide by -2 both sides

[tex]u=(9-6w)/(-2)[/tex]

[tex]u=3w-4.5[/tex]

Answer: u = -9/2 + 3w

Step-by-step explanation:

Hi, An Independent Variable in an Equation is a variable that may have its value freely chosen without considering values of any other variable. Is also known as the input value of a function.

So, to rearrange we have to isolate u:

-2u+6w=9

-2u =9 -6w

2u = -9 +6w

u= (-9 +6w)/2

u = -9/2 + 3w

Step-by-step explanation: the first line is the min and the next is q1 and then the medium and q3 max

Shown below

This is a step function which is a type of function defined by two or more functions. To write the function, we can follow these steps:

STEP 1. A linear function.

This function goes from [tex]-\infty[/tex] to [tex]2[/tex] without including this last value in the domain because at [tex]x=2[/tex] we have a hole. By writing the equation:

[tex]The \ equation \ of \ the \ line \ with \ slope \ m \\ passing \ through \ the \ point \ (x_{1},y_{1}) \ is:\\ \\ y-y_{1}=m(x-x_{1})[/tex]

So:

[tex]P_{1}(1,0) \\ P_{2}(2,2) \\ \\ y-0=\frac{2-0}{2-1}(x-1) \\ \\ y=2(x-1) \therefore \boxed{y=2x-2}[/tex]

[tex]f(x)=2x-2, \ \ -\infty<x \leq 2[/tex]

STEP 2. Constant function.

This function goes from [tex]2[/tex] to [tex]5[/tex] including both values in the domain because at [tex]x=2[/tex] and at [tex]x=5[/tex] we have dots.

So:

[tex]f(x)=4, \ \ 2 \leq x \leq 5[/tex]

STEP 3. Linear function.

This is also a linear function but goes from [tex]5[/tex] to [tex]+\infty[/tex] without including [tex]x=5[/tex] in the domain because we have a hole here. By writing the equation:

So:

[tex]P_{1}(5,6) \\ P_{2}(6,7) \\ \\ y-6=\frac{7-6}{6-5}(x-5) \\ \\ y=x-5+6 \therefore \boxed{y=x-1}[/tex]

[tex]f(x)=x+1, \ \ 5<x \leq +\infty[/tex]

Finally, our step function is:

[tex]f(x)=\left\{ \begin{array}{c}2x-2,\;-\infty<x\leq2\\4,\;2\leq x\leq5\\x+1,\;5<x\leq+\infty\end{array}\right.[/tex]

Answer:

12x + 30y

156

Step-by-step explanation:

To use the distributive property, you multiply the number or quantity outside the parentheses (6 in this problem) by each of the numbers or quantities inside the parentheses (2x and 5y in this problem).

You started out correctly writing 6(2x), but then you must multiply 6 by 5y too, so you should get 6(2x) + 6(5y). Then you do the two multiplications to get 12x + 30y.

Here are the steps:

6(2x + 5y) =

= 6(2x) + 6(5y)

= 12x + 30y

The expression is: 12x + 30y

Now we use the expression with the values x = 3 and y = 4 to find the area.

12x + 30y =

= 12(3) + 30(4)

= 36 + 120

= 156

Answer:

Box=0.95

Orange bag=0.44

Package=0.44

Step-by-step explanation:

Divide the cost by the amount of whatever. For ex. The 3.79/4 because there are 4 boxes.

Final answer:

The unit rate for a box of 4 light bulbs is $0.95 per bulb, for a bag of 5 oranges it's $0.44 per orange, and for a package of 12 bars of soap, the unit rate is $0.44 per bar.

Explanation:

To calculate the unit rate for each item, you divide the total cost by the number of items in the package. This tells you the cost per single item. Let's calculate the unit rates, rounding to the nearest cent.

Remember, when working with prices, it's standard practice to round to the nearest cent, which represents the smallest unit of currency used in transactions.
