13. A certain town with a population of 100,000 has 3 newspapers: I, II, and III. The proportions of townspeople who read these papers are as follows: I: 10 percent I and II: 8 percent I and II and III: 1 percent II: 30 percent I and III: 2 percent III: 5 percent II and III: 4 percent (The list tells us, for instance, that 8000 people read newspapers I and II.) Find the number of people who read only one newspaper. How many people read at least two newspapers

Answers

Answer:

a) the number of people who read only one newspaper is 20,000

b) number of people read at least two newspapers is 12,000

Step-by-step explanation:

Given the data in the question;

A certain town with a population of 100,000 has 3 newspapers

a)Find the number of people who read only one newspaper

From the Venn-diagram illustrating the data in the question;

Number of that read only one paper will be;

=[ ([tex]I^{}[/tex]∩ [tex]II^{c}[/tex] ∩ [tex]III^{c}[/tex]) + ( [tex]I^{c}[/tex] ∩  [tex]II^{c}[/tex] ∩ [tex]III^{c}[/tex]) + ( [tex]I^{c}[/tex] ∩  [tex]II^{c}[/tex] ∩ [tex]III^{}[/tex]) ] × 100,000

= [ 1% + 19% + 0% ] × 100,00

= 20% × 100,000

= 20,000

Therefore, the number of people who read only one newspaper is 20,000

b) How many people read at least two newspapers;

Number of people read at least two newspapers will be;

= [ ([tex]I^{}[/tex]∩ [tex]II^{}[/tex] ∩ [tex]III^{c}[/tex]) + ( [tex]I^{}[/tex] ∩  [tex]II^{c}[/tex] ∩ [tex]III^{}[/tex]) + ( [tex]I^{c}[/tex] ∩  [tex]II^{}[/tex] ∩ [tex]III^{}[/tex]) + ( [tex]I^{}[/tex] ∩  [tex]II^{}[/tex] ∩ [tex]III^{}[/tex])  ] × 100,000

= ( 7% + 1 % + 3% + 1% ) 100,000

= 12% × 100,000

= 12,000

Therefore, number of people read at least two newspapers is 12,000

What is the GCF of 18 and 45? fast!!

Answers

Answer:

The GCF of 18 and 45 is 9

For smaller numbers you can simply look at the factors or multiples for each number and find the greatest common multiple of them.

For 18 and 45 those factors look like this:

. Factors for 18: 1,2,3,6,9 and 18

. Factors for 45: 1,3,5,9,15 and 45

As you can see when you list out the factors of each number, 9 is the greatest number that 18 and 45 divides into.

18 + 24

1. 3(6 + 9)
= 18 + 27
So, this is wrong.

2. 6(3 + 4)
= 18 + 24
So, this is correct!

3. 6(2 + 5)
= 12 + 30
So, this is wrong.

4. 9(2 + 3)
= 18 + 27
So, this is wrong.

So, in conclusion, number two is correct because using distributive property, we were able to get the answer of: 18 + 24.

CAP has vertices
C(-3,8),
A(3,-9),
and
P-1,-10).

What are the coordinates of the image of
A after the given composition of tranformations?

Dilation: center (0, 0); scale factor 5,
Translation: (x, y) (x-9,y +11).

Answers

Answer:

[tex]A'' = (6, -34)[/tex]

Step-by-step explanation:

Given (Points)

[tex]C = (-3,8)[/tex]

[tex]A = (3,-9)[/tex]

[tex]P = (-1,-10)[/tex]

Transformations:

Dilation: Center (0,0); Scale factor = 5

Translation: (x, y) --> (x-9,y +11).

Required

Determine the image of A

[tex]A = (3,-9)[/tex]

Apply the first transformation:

i.e. dilation by a scale factor of 5

[tex]A'=A * 5[/tex]

[tex]A'=(3,-9) * 5[/tex]

[tex]A'=(3* 5,-9* 5)[/tex]

[tex]A'=(15,-45)[/tex]

Apply the second transformation:

i.e. translation: (x, y) --> (x-9,y +11).

[tex]A'=(15,-45)[/tex]

[tex]A'' = (15 - 9, -45 + 11)[/tex]

[tex]A'' = (6, -34)[/tex]

Hence, the image of A is (6,-34)

what is the surface area of this shape?

Answers

Answer:

135.42 yd²

Step-by-step explanation:

Surface area of triangular prism = 2(BA) + PH

Where,

Triangular base area (BA) = ½bh = ½*4*3 = 6 yd²

Perimeter of triangular base (P) = 4 + 3.61 + 3.61 = 11.22 yd

Height of prism (H) = 11 yd

Surface area = 2(6) + 11.22 × 11

= 12 + 123.42

Surface area = 135.42 yd²

Answers

Answer:

(a) [tex]x = 60[/tex]

(b) [tex]x = 2.64[/tex]

(c) [tex]x=15[/tex]

Step-by-step explanation:

Solving (a):

[tex]\frac{1}{4}x + \frac{2}{5}x = 39[/tex]

[tex]\frac{x}{4} + \frac{2x}{5} = 39[/tex]

Take LCM

[tex]\frac{13x}{20} = 39[/tex]

Multiply through by 20

[tex]20 * \frac{13x}{20} = 39 * 20[/tex]

[tex]13x = 39 * 20[/tex]

[tex]13x = 780[/tex]

Solve for x

[tex]x = 780/13[/tex]

[tex]x = 60[/tex]

Solving (b):

[tex]0.6x + 0.5x = 2.9[/tex]

This gives:

[tex]1.1x = 2.9[/tex]

Solve for x

[tex]x = \frac{2.9}{1.1}[/tex]

[tex]x = \frac{29}{11}[/tex]

[tex]x = 2.64[/tex]

Solving (c):

[tex]\frac{3}{5}x = 9[/tex]

Multiply both sides by [tex]\frac{5}{3}[/tex]

[tex]\frac{5}{3}*\frac{3}{5}x = 9 * \frac{5}{3}[/tex]

[tex]x = 9 * \frac{5}{3}[/tex]

[tex]x = \frac{9 *5}{3}[/tex]

[tex]x = \frac{45}{3}[/tex]

[tex]x=15[/tex]
