Answer:

  $67,516

Step-by-step explanation:

"Depreciates" means the value is getting smaller. The function that describes the situation is a decay function:

  y= a(1-r)^x

Here, a=150000, r = 0.07, and x=11. The value is predicted to be ...

  y = 150000(1 -0.07)^11 = 150000(0.93^11) = 67,515.53

The house is worth about $67,516 in 2013.

Answer: x => -6

Step-by-step explanation: All you gotta do is alternate the form

The solution for the given inequality is x ≥ -6.

A declaration of an order connection between two numbers or algebraic expressions, such as greater than, equal to, less than, less than, or equal to. Either questions or theorems can be used to express inequality problems, and both can be solved using methods similar to those used to solve equations. The triangle inequality, for instance, stipulates that the length of the remaining side of a triangle is more than or equal to the sum of the lengths of any two of its sides. Many of these inequalities, like the Cauchy-Schwarz inequality, are used by mathematical analysis to prove some of its most significant theorems.

Given an equation -3−4x ≤ 21.

Solve for x

-3−4x ≤ 21

add three to both sides

-4x ≤ 24

divide by -4 into both sides (signs will be changed)

Answer:

Explained below.

Step-by-step explanation:

The rules of the deal are as follows:

(a)

The correct option is: "the money you win".

(b)

The random variable X denotes the amount won or lost.

(c)

The value of X are as follows:

X = {-$6, $5 and $10}

(d)

The probability function of X is as follows:

P (X = 10) = 1/6

P (X = 5) = 1/3

P (X = -6) = 1/2

(e)

Compute the expected value as follows:

[tex]E(X)=\sum x\times P(X=x)\\[/tex]

         [tex]=(10\times\frac{1}{6})+(5\times\frac{1}{3})+(-6\times\frac{1}{2})\\\\=0.333333\\\\\approx $0.33[/tex]

Thus, the average winnings per game is $0.33.

Answer:

The critical t-value for such a test given an alpha level of 0.05 is 2.26

Step-by-step explanation:

Null hypothesis : [tex]H_0:\mu = 7.5[/tex]

Alternate hypothesis :[tex]H_a:\mu \neq 7.5[/tex]

Population mean = [tex]\mu = 7.5[/tex]

Data : 10, 9, 6, 11, 13, 14, 9, 9, 9, and 10

Mean = [tex]\bar{x}=\frac{\text{Sum of all observations}}{\text{no. of observations}}[/tex]

Mean =[tex]\frac{10+9+6+11+13+14+9+9+ 9+ 10}{10}[/tex]

Mean =10

Standard deviation : [tex]\sqrt{\frac{\sum(x-\bar{x})^2}{n}}[/tex]

Standard deviation :[tex]\sqrt{\frac{(10-10)^2+(9-10)^2+(6-10)^2+(11-10)^2+(13-10)^2+(14-10)^2+(9-10)^2+(9-10)^2+(9-10)^2+(10-10)^2}{10}}[/tex]

Standard deviation s :2.144

[tex]t = \frac{x-\mu}{\frac{s}{\sqrt{n}}}t = \frac{10-7.5}{\frac{2.144}{\sqrt{10}}}t=3.687[/tex]

Df = n-1 = 10-1 = 9

T critical =[tex]t_{(df,\alpha)}=t_(9,0.05)=2.26[/tex]

T calculated > T critical

So, We failed to accept null hypothesis

Hence the critical t-value for such a test given an alpha level of 0.05 is 2.26

Option (A)

Step-by-step explanation:

Graph attached shows a function that models the value V of a stock portfolio as a function of time.

y-values on the graph shows the value of V and x-values represent the time.

Lowest point of the curve shows the minimum value of V and highest point of the curve shows the maximum value.

Maximum value of the function → 6.93 at t = 4

Minimum value of the function → 1.05 at t = 15

Therefore, Option (A) will be the answer.

Answer:

Answer is D.

Step-by-step explanation:

Which is not true?

So, lets assess the answers given to the question.

A. It is the equation of a horizontal line.

Yes, it is. Since there is only one y - value which is y = -4, we can confirm this is the y intercept, so therefore the x value is zero. But it's not the answer we're looking for.

B. It's slope is zero, yes the slope is zero. It only lists the y-intercept which confirms that the slope is 0.

C. Yes, I mean i can't really explain how. Just use desmos calculator, the graph is exactly perpendicular.

D. The line actually does cross the x-axis, -4 is the y intercept and the x value is 0, and zero is still a point. So D is the one which isn't correct making it the correct answer.

5.) x>20

11.)x≤−15

13.)x≥−21

2.)x≤−7

6.)x≤−45

10.)x≤10

12.)x≥−12

16.)x≤−4

Answer:

2. x ≤ -7

5. x > 36

6. x ≤ -40

10. x ≤ 10

11. x ≤ -15

12. x ≥ -12

13. x ≥ -21

16. x ≤ -4

Step-by-step explanation:

2. x ≤ -7 (You want to add 8 to both sides like any equation, but don't forget it is an inequality, not an equation!)

5. x > 36 (You need to multiply by 2, to get rid of the division. So multiply both sides by 2, that gets rid of the 2 on the one side, and you get 36 on the other side when you multiply 18 by 2).

6. x ≤ -40 (You need to multiply by -5. REMEMBER: When you multiply or divide by a negative, you switch the sign. So if it is a < then it would be a > and same with if you had ≤ then it would be ≥ instead).

10. x ≤ 10 (You need to divide by -2. And once again you switch the signs).

11. x ≤ -15 (Add 8, like you did in number 2).

12. x ≥ -12 (Multiply by 6. REMEMBER: Do NOT switch the signs if you the number you are dividing by is in the numerator, or if you multiply and the negative number is first, UNLESS you have 2 negatives.

13. x ≥ -21 (Multiply by 7).

16. x ≤ -4 (Divide by 10).

Answer:

Options 1) and 3) are correct.

Step-by-step explanation:

R={(A,B)|A⊆B}

Reflexive:

As A⊆A,  [tex](A,A)[/tex]∈ R.

So, R is reflexive

Symmetric:

Let [tex](A,B)[/tex]∈ R. So, A⊆B

Take [tex]A=\{1,2\}\,,\,B=\{1,2,3,4\}[/tex]

Here, A⊆B but B⊄A

So, [tex](B,A)[/tex]∉ R

R is not symmetric

Transitive:

Let [tex](A,B)[/tex]∈ R and [tex](B,C)[/tex]∈ R

So, A⊆B and B⊆C.

Therefore, A⊆C

So,

[tex](A,C)[/tex]∈ R

Hence, R is transitive.

Option 1) is correct.

Antisymmetric:

Let (A,B)∈R and (B,A)∈R

So, A⊆B and B⊆A

Hence, A = B

So, R is antisymmetric

Option 3) is also correct.

Answer:

None of the options are correct, but I got g(x)=1/2x+2.

Step-by-step explanation:

You start with the equation. You first need to change f(x) to y, and switch the x and y values. After this, your equation would be x=2y-4. Then, you need to icolate the y value, and to do that you first cancel out the four by adding it to both sides, and now your equation should be x+4=2y. The second step in icolating the y value is dividing everything in the equation by two. Now that the y is icolated, you equation should be y=1/2x+2. You then change the y to be g(x), and that's how I got my answer, g(x)=1/2x+2. You should ask your teacher about this, becuase from my calculations, none of the given responses would be correct. Sorry if that doesn't help you at all but yeah

The number line which can be used to find the distance between (4, -1) and (8,-1) is 1

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

[tex]D = √[(x-p)² + (y-q)²] D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]

Given the points;

(x1, y1) = (4, -1)

(x2, y2) = (8, -1)

Here, we have the same values of y for both points.

This means that the line that contains both points is a horizontal line.

To find the distance, apply the formula:

[tex]d= \sqrt{(x2-x1)^{2} + (y2-y1)^{2} }[/tex]

Since they have the same y values, the number line to represent the distance between both points must have the points 4 and 8;

Hence, we have;

 [tex]d= \sqrt{(8-4)^{2}+(-1+1)^{2} }[/tex]

   [tex]d= \sqrt{4^{2} + 0^{2} }[/tex]

     d= 4

The distance between both points is 4;

Therefore, the number line that can be used to find the distance between both points is the number line in option A.

Answer:

y = 1/2x + 2.5

Step-by-step explanation:

First we want to plug it into the [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]. This gets us 6-2/7-(-1) which solves to 4/8 which simplifies to 1/2. This gives us the slope. Now, when using slope intercept form y = mx + b, we can plug our newly found slope in for m and get y = 1/2x + b. To find b plug in any point on the line into the equation, I chose (7,6) because we are given that, and both numbers are positive. Now plug those in for x and y. 6 = 1/2(7). Solve, and get 2.5. are final equation is
