Answer:

Identity Solution

Step-by-step explanation:

9x+6 = 3(3x + 2)

9x + 6 = 9x + 6

0x = 0

Answer:

21.9%

Step-by-step explanation:

7000000/32000000=0.21875

move the decimal over two places to get percent and round the 8 up because of the 7. 21.9%

Answer: The center is (-5,2)

The radius is 5

Step-by-step explanation:

Equation of a circle is:

(x-h)^2+(y-k)^2=r^2

(x+5)^2+(y-2)^2=5^2

Comparing both equations we get :

The center (-5,2)

The radius is 5

Hope This Helps :)

Answer:

(1/2, -1/2)

Step-by-step explanation:

To find a midpoint add the two x's and divide by 2 so -1+2 / 2 = 1/2

add the two y's and divide by 2 so 4-5 / 2 = -1/2

Put the two numbers together as a coordinate (1/2, -1/2)

Answer:

There are 6 different shapes

You want the outcome to be a Nonagon

You put the outcome as a ratio 1/6

1/6=0.1666667

0.1666667*100=16.6667%

Chance of pulling out a nonagon

Answer:

When we combine like terms we get 158 plus 2x equals 360 subtract 158 from both sides. And we get 2x...

Answer:

x=45

Step-by-step explanation:

This is a triangle so it interior degrees will add up to 180.

W

Since Line AC is tangent to Circle O at point c, Point C measures 90 degrees.

We can find OAC by using the triangle interior theorem,

[tex]45 + 90 + x = 180[/tex]

[tex]135 + x = 180[/tex]

[tex]x = 45[/tex]

Answer:

x to the 4th power+ 87x + 34

Step-by-step explanation:

Answer:

Formula for both is: A= (h•b)/2

Plug in values for First one are: 16 and 14

Area of first one: 112in^2

Plug in values for Second one: 2 and 3.5

area of second one: 3.5m^2

Step-by-step explanation:

plug in the values-. A= 16•14= 224 224÷2= 112

plug in the values #2- A= 2•3.5= 7 7÷2= 3.5

Answer:

2 minutes 10 seconds = 130 seconds

Step-by-step explanation:

Given that,

LHS = 2 minutes 10 seconds

RHS = 130 seconds

Solving LHS first,

We know that,

1 minute = 60 seconds

2 minute = 120 seconds

2 minutes 10 seconds = 120s + 10 s

= 130 seconds

It means,

LHS = RHS

So,

2 minutes 10 seconds = 130 seconds

Answer:

1a ) N_6 = 50 mg

1b) N_3 = 70.7 mg

1c) N_1 = 89.1 mg

2) f(t) = 100e^(-0.1155t)

Step-by-step explanation:

Formula to get amount remaining is;

N_t = N_o × ½^(t/t_½)

We are given;

N_o = 100 mg

t_½ = 6 years

We have; N_t = 100(½^(t/6))

Thus;

1a) amount left after 6 years is;

N_6 = 100 × ½^(6/6)

N_6 = 50 mg

1b) amount left after 3 years is;

N_3 = 100 × ½^(3/6)

N_3 = 70.7 mg

1c) amount left after 1 year is;

N_1 = 100 × ½^(1/6)

N_1 = 89.1 mg

2) to find the function to model the amount left after t years, let's use the formula;

f(t) = f_o × e^(-rt)

Where r is decay constant

Thus;

f(t) = 100e^(-rt)

We recall that N_t = 100(½^(t/6))

Thus;

100(½^(t/6)) = 100e^(-rt)

Divide both sides by 100 to get;

(½^(t/6)) = e^(-rt)

In (½^(t/6)) = In e^(-rt)

Using power rule, we have;

(t/6) In ½ = -rt In e

-0.6931t/6 = - rt (because In e = 1)

t will cancel out to give;

r = 0.6931/6

r = 0.1155

Thus;

f(t) = 100e^(-0.1155t)

your answer I think would be 20 miles

Answer:

a. The independent variable is the activity level

The dependent variable is the body composition (the percentage of body fat in the values)

b. The mean and standard deviation are;

(Mean, Standard deviation)

Inactive(27.13, 5.8), Semiactive(24.97, 4.367), Normal(22.217, 2.73), Active(16.12, 3.73),  Very Active (12.35, 1.95)

c. Yes

Between Semiactive and Active, Semiactive and Very Active, Normal and Very Active, Normal and Active, Active and Inactive, and Inactive and Very Active

Step-by-step explanation:

a. The independent variable is the activity level

The dependent variable is the body composition (the percentage of body fat in the values)

b. The given data are presented as follows;

Inactive [tex]{}[/tex]  Semiactive   Normal  Active   Very Active

30.2  [tex]{}[/tex]      29.4               22.9       17.6       10.9

29.6 [tex]{}[/tex]       17.6                25.4        13.4      13.7

35.2   [tex]{}[/tex]     26.4               19.6         20.3     12.8

19.1   [tex]{}[/tex]       25.3               18.7          19.6      14.7

26.3 [tex]{}[/tex]       22.5               21.8          15.1       9.3

22.4   [tex]{}[/tex]     28.6               24.9         10.7       12.7

Bymaking use of Microsoft Excel, we have;

                                  Inactive [tex]{}[/tex]  Semiactive   Normal    Active   Very Active

Mean                           27.13  [tex]{}[/tex]      24.97            22.217       16.12       12.35

Standard Deviation     5.8 [tex]{}[/tex]  [tex]{}[/tex]       4.367              2.73         3.73         1.95

c. Yes

[tex]t=\dfrac{(\bar{x}_{1}-\bar{x}_{2}) }{\sqrt{\dfrac{s_{1}^{2} }{n_{1}}-\dfrac{s _{2}^{2}}{n_{2}}}}[/tex]

The degrees of freedom = n - 1 = 6 - 1 = 5

The critical t = 2.5706

Therefore, we have;

The test statistic for Inactive and semi active ≈ 0.72875

The test statistic for Semiactive Normal ≈ 1.309

The test statistic for Inactive and Normal ≈ 1.8773

The test statistic for Semiactive and Active ≈ 3.775 (Significant)

The test statistic for Semiactive and Very Active ≈ 6.464  (Significant)

The test statistic for Normal and Very Active ≈ 7.204  (Significant)

The test statistic for Normal and Active ≈ 3.231  (Significant)

The test statistic for Active and Inactive ≈ 3.91  (Significant)

The test statistic for Active and Very Active ≈ 2.194

The test statistic for Inactive and Very Active ≈ 5.92  (Significant)

Where the test statistic is larger than the critical 't' the statistic is significant
