Answer: The car is worth $ 2,588.6 after two years than after 3 years.

Step-by-step explanation:

x=2

v(x)=25,000(0.86)^2

v(x)=18,490

x=3

v(x)=25,000(0.86)^3

v(x)=15,901.4

18,490 - 15,901.4= 2588.6

Given:

The inequality is:

[tex]x>3[/tex]

To find:

The negation of the given inequality.

Solution:

The given inequality is [tex]x>3[/tex], it means all the value which are greater than 3 are included in the solution set.

Since all the values which are less than or equal 3 are not included in the solution set, therefore the negation of the given inequality is

[tex]x\leq 3[/tex]

Therefore, the negation of [tex]x>3[/tex] is [tex]x\leq 3[/tex].

Representative Sample                  Residents randomly chosen from the

                                                        town register

Step-by-step explanation:

Population includes all the residents of Middlefield.

Representative Sample is a population subset that accurately reflects the characteristics of the population.  For example, the subset of residents who are randomly chosen from the town register is an unbiased and representative sample.

NOT a Representative Sample: For example, drivers who reside in Middlefield do not represent the characteristics of the population of Middlefield.

Answer:

the third one is correct

Answer:

The formula to find the value of the side is X ^ 3 = 10, and the side measures 2.15 cm.

Step-by-step explanation:

Given that a Rubik's Cube has a volume of 10 cm, to write an equation to find the length of the sides and find the length of the side to the nearest tenth, the following calculations must be performed, knowing that the volume of a cube is obtained to enhance one of its sides to the third:

X ^ 3 = 10

X = 3√ 10

X = 2.15

Thus, the formula to find the value of the side is X ^ 3 = 10, and the side measures 2.15 cm.

Answer:

5000 pounds

Step-by-step explanation:

Hello There!

There are 2000 pounds in 1 ton

So to convert tons to pounds we multiply by 2000

2.5x2000=5000

So 2.5 tons is the equivalent if 5000 pounds

The term BEST describes the two angles and will be supplementary. Then the correct option is C.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.

The types of angles are as follows:

Step-by-step explanation:

Answer:

fifteen percent xx

Step-by-step explanation:

Step-by-step explanation:

total = 315+101+108+32 = 556

total ratio = 9+3+3+1 = 16

1.

h0 : data follows ratio 9:3:3:1

h1: data does not follow ratio 9:3:3:1

2. expected counts under h0

Ei = expected count, i = 1,2,3,4

count 315

ratio = 9

Ei = 9*556/16

= 312.75

count 101

ratio = 3

Ei = 3*556/16

= 104.25

count 1o8

Ei 3 x 556/16

= 104.25

count 32

= 1*556/16

= 34.75

total = 312.75+104.25+104.25+34.75 = 556

c. value of chi² test stat

a. Oi = 315

Ei = 312.75

X² = (315-312.75)²/312.75

= 0.01618705

b. (101-104.25)²/104.25

x² = 0.101318944

c. (108-104.25)²/104.25

= 0.134892086

d. (32-34.75)²/34.75

= 0.217625859

Chi² test stat = 0.01618705+0.101318944+0.134892086+0.217625859

= 0.470023981

n = 4

df = 4-1 = 3

test stat = 0.4700

critical x² = 7.814736

p value = 0.9254

α < pvalue

0.05<0.9254

we therefore fail to reject the h0. we conclude that it follows 9:3:3:1

Answer:

1975------ 4.8%

1990 ------ 11.48%

1985 ------ 8.51%

Step-by-step explanation:

Given

[tex]P(t) = 0.04t + 4.6[/tex] if 0 ≤ t < 10

[tex]P(t) = -0.01005t^2 + 0.945t - 3.4[/tex] if 10 ≤ t ≤ 30

Where

t:=0 implies year = 1970

Solving (a): Beginning of 1975.

First, we calculate the value of t

[tex]t = 1975 - 1970[/tex]

[tex]t = 5[/tex]

This falls in the range: 0 ≤ t < 10

So:

[tex]P(t) = 0.04t + 4.6[/tex]

[tex]P(5) = 0.04 * 5 + 4.6[/tex]

[tex]P(5) = 4.80[/tex]

Solving (b): Beginning of 1990.

[tex]t = 1990 - 1970[/tex]

[tex]t = 20[/tex]

This falls in the range: 10 ≤ t ≤ 30

So:

[tex]P(t) = -0.01005t^2 + 0.945t - 3.4[/tex]

[tex]P(20) = -0.01005*20^2 + 0.945*20 - 3.4[/tex]

[tex]P(20) = 11.48[/tex]

Solving (c): Beginning of 1985

[tex]t = 1985 - 1970[/tex]

[tex]t = 15[/tex]

This falls in the range: 10 ≤ t ≤ 30

So:

[tex]P(t) = -0.01005t^2 + 0.945t - 3.4[/tex]

[tex]P(15) = -0.01005*15^2 + 0.945*15 - 3.4[/tex]

[tex]P(15) = 8.51375[/tex]

[tex]P(15) = 8.51[/tex]

Rational and whole numbers

Step-by-step explanation:

7x7=49 which is a whole number which automatically makes it rational!

The answer would be x=18. First you set it up by setting up an equation;

166=7x+40. Then you subtract 40 from each side. Last, you divide both sides by 7 and you should get x=166 or 166=x.  

Answer:

Point Q:  ( 6, 6)

Step-by-step explanation:

    (10, 10)

- 2 (8, 8)

      ( 6, 6)

Answer:

Point Q is at (6, 6).

Step-by-step explanation:

Segment QR has a midpoint M at (8, 8).

Point R is at (10, 10), and we want to determine the location of Point Q.

First, recall that the midpoint is given by the formula:

[tex]\displaystyle M=\Big(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\Big)[/tex]

We will let R(10, 10) be (x₁, y₁). We are also given that M is at (8, 8). Therefore:

[tex]\displaystyle (8, 8)=\Big(\frac{10+x}{2}, \frac{10+y}{2}\Big)[/tex]

This gives us two cases:

[tex]\displaystyle \frac{10+x}{2}=8\text{ and } \frac{10+y}{2}=8[/tex]

Solve for each case. Multiply both sides by 2:

[tex]10+x=16\text{ and } 10+y=16[/tex]

And we can subtract 10 from both sides:

[tex]x=6\text{ and } y=6[/tex]

Therefore, Point Q is at (6, 6).
