Using the permutation formula, it is found that the probability that the CDs end up in alphabetical order is:

[tex]p = \frac{1}{8,204,716,800}[/tex]

For this problem, the order in which the CDs are chosen is important, hence the permutation formula is used to solve this question.

The number of possible permutations of x elements from a set of n elements is given by:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

8 CDs are chosen from a set of 21, hence the number of ways they can be chosen is:

[tex]P_{(21,8)} = \frac{21!}{13!} = 8204716800[/tex]

Only one arrangement is in alphabetical order, hence the probability is:

Answer:

71°

Step-by-step explanation:

So, angle A measures 66+5=71°

Answer:

Center of the Sphere is a fixed point in its interior which is equidistant from each point on sphere. Option A is not right because it says center is line segment. Option B is right as it says it is fixed and equidistant from point of surface.

Step-by-step explanation:

The measure of <2 is 60.

The tangent is defined as a line touching circles or an ellipse at only one point.

Answer:

Therefore the slope is 13

Step-by-step explanation:

Using Slope intercept formula y = mx + b.

Note : m is the slope ( the number near x).

y+6=13(x−4)

y+6 = 13x - 52

Add -6 to both sides

y+ 6- 6 = 13x- 52- 6

y= 13x -58

The most suitable viewing window to solve the system is -20 ≤ x ≤ 20 and -15 ≤ x ≤ 15 option fourth is correct.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have two linear equations:

0.02x - 0.05y =  -0.38

0.03x + 0.04y = 1.04

We can write above equations as follows:

2x - 5y = -38

3x + 4y = 104

After solving with the substitution method:

x = 16

y = 14

-20 ≤ x ≤ 20

-15 ≤ x ≤ 15

For systems A and B we have:

1) Change the first equation in A by a multiple of itself. (the multiple is 1/3).

2) Yes, the systems are equivalent.

Here we have the systems of equations:

A:

-3x + 12y = 15

7x - 10y = -2

B:

-x + 4y = 5

7x - 10y = -2

Notice that the second equation is the same in both systems, so we only need to work with the first ones.

If we take the first equation in system A:

-3x + 12y = 15

If we divide both sides by 3, we get:

-x + 4y = 5

Which is the first equation of B.

So we just need to replace the first equation in system A by a multiple of itself to get system B.

Because of that, we conclude that both systems are equivalent (because are made of the same equations) which means that both systems have the same solutions.

Answer: C), Yes

Step-by-step explanation:

Answer:

D(t)=60+23*sin(2*pi*t/24)+26*cos(2*pi*t/24)

Step-by-step explanation:

The temperature at any time t can be represented as:

D(t)=A+B*sin(2*pi*t/T)+C*cos(2*pi*t/T)

where A is the average temperature, B is the amplitude of the sine wave, C is the amplitude of the cosine wave, and T is the period.

In this case, we are given that the average temperature is 60, the high temperature is 73, and the low temperature is 47. We can therefore calculate that the amplitude of the sine wave is 23 and the amplitude of the cosine wave is 26. The period is 24 hours. Therefore, the equation for the temperature in terms of time is:

D(t)=60+23*sin(2*pi*t/24)+26*cos(2*pi*t/24)

The equation of the segments perpendicular bisector is; y = -¹/₂x + 2

i) Since it is a perpendicular bisector, hence point M is the midpoint. Thus;

Midpoint (AB) = [(x₁ + x₂)/2], [(y₁ + y₂)/2] = (x_m, y_m)

Slope AB will be;

m₁ = ((x₁ - x₂)/(y₁ - y₂))

Slope of perpendicular bisector is;

m₂ = -1/m₁

Equation of perpendicular bisector is;

(y - y_m) = m₂(x - x_m)

ii) Midpoint (AB) = [(-2 + 6)/2], [(3 - 1)/2] = (2, 1)

Slope AB will be;

m₁ = ((6 + 2)/(-1 - 3)) = -2

m₂ = -1/-2 = 1/2

x + 120 = 180

25 + x + y = 180

flipping the first equation 180 - 120 = 60 so x is 60.

so plug in 60 into the second equation

25 + 60 + y =180 --> 85 + y =180 flip equation 180 - 85 = 95

Answer:

Olive's age = 32

Lisbeth's age = 8

Step-by-step explanation:

Declaration

Let Eisbeths present age = x

Let Olive's age = y

Equations

(x - 2) = 1/5 (y - 2)

x + 4 = 1/3(Y + 4)

Solution

1st equation

(x - 2) = 1/5 (y - 2)                 Multiply both sides by 5

5(x - 2) = y - 2                       Remove the brackets

5x - 10 = y - 2                       Add 10 to both sides

5x -10+10 = y - 2+10            Combine

5x = y + 8                            Subtract 8 from both sides

5x - 8 = y + 8 - 8                 Combine

5x - 8 = y

2nd Equation

x + 4 = 1/3(y + 4)                 Multiply both sides by 3

3(x + 4) = y + 4                   Remove the brackets

3x + 12 = y + 4                     Subtract 3 from both sides

3x + 12 - 4 = y + 4 - 4          Combine

3x + 8 = y

Note Since y is the same in both equations, the left side of each can be thought of as equal to each other.

3x + 8  = 5x - 8                    Add 8  to both sides

3x + 8 + 8 = 5x - 8 + 8        Combine

3x + 16 = 5x                         Subtract 3x from both sides

3x - 3x + 16 = 5x - 3x           Combine

16 = 2x                                  Divide by 2

16/2 = 2x/2

8  = x

y = 3x + 8

y = 32

The company should focus attention on 17515 people.

The term percentage means a denominator of 100. We can proceed to find the people to which the company must reach as follows;

The percentage that is over the age of 65, and immunocompromised =  27%

so;

27/100 × 50,000 = 13500 people

50,000 - 13500 = 36,500

Now;

11% of this number are under 65 and immunocompromised so;

11/100 ×  36,500 = 4015 people

Total number that the company should reach = 13500 + 4015  = 17515 people

Answer:

-2 3/8

Step-by-step explanation:

since point A is left of 0, it means it is a negative value.

so, the positive answer options are automatically out.

then we see that point A is 2 full units and a little bit left of 0.

that means it has to be lower than -2 but higher than -3.

-22/7 = -3 1/7

so, that is too low.

-3 7/8 is too low.

so, that leaves -2 3/8 (confirmed also by the fact that A is a little bit higher than half between -2 and -3, which is the case for -2 3/8).

Answer:

the MEAN for class a is 72.6

the MEAN for class b is 84.0

if you take these means and compare them, you can see that on average, class B performed better.

The function g(x) is [tex]g(x) = (x + 7)^3[/tex]

The function f(x) is given as:

[tex]f(x) = \sqrt[3]{x} - 7[/tex]

If f(g(x)) = g(f(x)) = x, then the functions are inverse functions.

So, we have:

[tex]f(x) = \sqrt[3]{x} - 7[/tex]

Rewrite as:

[tex]y = \sqrt[3]{x} - 7[/tex]

Swap x and y

[tex]x = \sqrt[3]{y} - 7[/tex]

Add 7 to both sides

[tex]x + 7 = \sqrt[3]{y}[/tex]

Take the cube of both sides

[tex]y = (x + 7)^3[/tex]

This implies that

[tex]g(x) = (x + 7)^3[/tex]

Hence, the function g(x) is [tex]g(x) = (x + 7)^3[/tex]

a. The unit rate is 9 d per t

b. Find the graph in the attachment

To graph the line, we need to find its gradient or unit rate

Since t has an increase of 0.20 units in t corresponds to an increase of 1.8 units in d.

The gradient or unit rate of change is m = change in d/change in t

= Δd/Δt

Since

So, substituting the values of the variables into the equation, we have

m = Δd/Δt

= + 1.8 units/+ 0.2 units

= 9 d per t

So, the unit rate is 9 d per t

To graph the function, we need to know the equation of the graph.

So, the equation of a graph in gradient form is

m = (y - y')/(x - x') where (x', y') = (0, 0) since the graphs both start at the origin

Since m = 9, we have

m = (y - y')/(x - x')

9 = (y - 0)/(x - 0)

9 = y/x

y = 9x

So, the equation of the line is y = 9x
