Answer:

The answer would be 19,803.

Step-by-step explanation:

What helps when doing multiplication is lining the problem up, like so:

Find the exact area of the shaded region
GREYUIT [131]

Answer:

B: 192pi - 144

Step-by-step explanation:

Area of the sector = (120/360) * pi * r^2

Area of the sector = 1/3 * pi * 24 * 24

Area of the sector = 192 * pi

Now to find the area of the triangle.

The triangle is an isosceles triangle That means two of its sides are equal. They are equal to the radius of the circle, which is 24.

the small angles are equal to

2x + 120 = 180    Subtract 120 from both sides

2x = 60               Divide by 2

x = 60/2

x = 30

The height of the triangle is derived from sin(30) = opposite / hypotenuse

sin(30) = 1/2

hypotenuse = 24

1/2 = opposite / hypotenuse

1/2 = opposite / 24                      Multiply both sides by 24

1/2 * 24 = opposite

opposite = 12

The height = 12

r = 24

Area of the triangle = 1/2 * 12 * 24

Area of the triangle = 144

So the area of the shaded area = 192*pi - 144 which looks like B

The sum of two numbers is 62, and their difference is 12. What are the numbers?
Ede4ka [16]
X + y = 62 

x - y = 12

Move x over so y is alone in one of the above equations,

y = 62-x

Now substitte in y

x-(62-x) = 12

x - 62 + x = 12

2x = 12 + 62

2x/2 = 74/2

x = 37

Now for y sub in the x!

x + y = 62

(37) + y = 62

y = 62 - 37

y = 25.

So 25 + 37 =62

and 37 - 25 = 12


Method 2 :
Start by stacking the 2 original equations from above,

x+y=62
x-y=12
You want to "cancel" out one of the variable so,

x+y=62
+  +  =  +
x - y =12

So then you add,

2x = 74

2x / 2 = 74 / 2

x = 37.

Now you can once again sub it back into the original equation to solve for y,

x+y=62
(37)+y=62
y=62-37
y=25

Hope this helps!

Let X be the number of the cars being repaired at a repair shop. We have the following information:
worty [1.4K]

Answer:

(a) Sample Space

S = \{0,1,2,3\}

(b) PMF

\begin{array}{ccccc}x & {0} & {1} & {2} & {3} \ \\ {P(x)} & {1/3} & {1/6} & {1/6} & {1/3} \ \end{array}

(c) CDF

\begin{array}{ccccc}x & {0} & {1} & {2} & {3} \ \\ {F(x)} & {1/3} & {1/2} & {2/3} & {1} \ \end{array}

Step-by-step explanation:

Solving (a): The sample space

From the question, we understand that at most 3 cars will be repaired.

This implies that, the number of cars will be 0, 1, 2 or 3

So, the sample space is:

S = \{0,1,2,3\}

Solving (b): The PMF

From the question, we have:

P(2) = P(1)

P(0) = P(3)

P(1\ or\ 2) = 0.5 * P(0\ or\ 3)

P(1\ or\ 2) = 0.5 * P(0\ or\ 3) can be represented as:

P(1) + P(2) = 0.5[P(0) + P(3)]

Substitute P(2) = P(1) and P(0) = P(3)

P(1) + P(1) = 0.5[P(0) + P(0)]

2P(1) = 0.5[2P(0)]

2P(1) = P(0)

P(0)= 2P(1)

Also note that:

P(0) + P(1) + P(2) + P(3) = 1

Substitute P(2) = P(1) and P(0) = P(3)

P(0) + P(1) + P(1) + P(0) = 1

2P(1) + 2P(0) = 1

Substitute P(0)= 2P(1)

2P(1) + 2*2P(1) = 1

2P(1) + 4P(1) = 1

6P(1) = 1

Solve for P(1)

P(1) = \frac{1}{6}

To calculate others, we have:

P(2) = P(1)

P(2) = P(1) = \frac{1}{6}

P(0)= 2P(1)

P(0) =2 * \frac{1}{6}P(0) =\frac{1}{3}

P(3) = P(0) =\frac{1}{3}

Hence, the PMF is:

\begin{array}{ccccc}x & {0} & {1} & {2} & {3} \ \\ {P(x)} & {1/3} & {1/6} & {1/6} & {1/3} \ \end{array}

<em>See attachment (1) for histogram</em>

Solving (c): The CDF ; F(x)

This is calculated as:

F(x) = P(X \le x) =\sum\limit^{3}_{x_i \le x}  P(x_i)

For x = 0;

We have:

P(X \le 0) = P(0)

P(X \le 0) = 1/3

For x = 1

P(X \le 1) = P(0) + P(1)

P(X \le 1) =  1/3 + 1/6

P(X \le 1) =  1/2

For x = 2

P(X \le 2) =  P(0) + P(1) + P(2)

P(X \le 2) =  1/3 + 1/6 + 1/6

P(X \le 2) =  2/3

For x = 3

P(X \le 3) =  P(0) + P(1) + P(2) + P(3)

P(X \le 3) =  1/3 + 1/6 + 1/6 + 1/3

P(X \le 3) =  1

Hence, the CDF is:

\begin{array}{ccccc}x & {0} & {1} & {2} & {3} \ \\ {F(x)} & {1/3} & {1/2} & {2/3} & {1} \ \end{array}
