In a random sample of 40 teenagers, 18 enjoy reading for fun, and in a random sample of 40 adults, 12 enjoy reading for fun. Do these data provide convincing evidence that the true proportion of adults who enjoy reading for fun is less than that of teenagers

Answers

Answer 1

Answer: Yes. The data provides convincing evidence.

Step-by-step explanation:

In a random sample of 40 teenagers, 18 enjoy reading for fun. The percentage of teenagers who enjoy reading for fun will be:

= 18/40 × 100

= 45%

In a random sample of 40 adults, 12 enjoy reading for fun. The percentage of adults who enjoy will be:

= 12/40 × 100

= 30%

Therefore, the proportion of adults who enjoy reading for fun is less than that of teenagers. Therefore, the data provides convincing evidence.

All angles in a triangle add up to 180°

Step-by-step explanation:

Step 1: Define

Identify and set up

6x° + 36° + 108° = 180°

Step 2: Solve for x

[Addition] Combine like terms:                                                                         6x° + 144° = 180°[Subtraction Property of Equality] Subtract 144° on both sides:                    6x° = 36°[Division Property of Equality] Divide 6 on both sides:                                 x = 6

Answers

Answer:

38.6 sq ft

Step-by-step explanation:

This composite figure consists of a trapezoid and a triangle on top

A(trapezoid) = 1/2h(sum of bases)

= 1/2(3.6)(7+9)

= 8(3.6)

= 28.8

A(triangle) = 1/2bh

base = 7

height = 6.4-3.6 which is 2.8

A = 1/2(7)(2.8)

= 3.5(2.8)

= 9.8

28.8 + 9.8 = 38.6

Answer:

7. x = 38°

8. y = 65°

9. 261° and 81°

Step-by-step explanation:

Finding x:

You can make an equality with (2x +5) and (3x +33) because the value of these angles are the same, so:

2x +5 = 3x -33

2x - 3x = -33 -5

-x = -38

x = 38°

Finding y:

You can find the value of y making another equally, but this time you have to sum (4y -1) with (3x - 33) or (2x +5) and equal it with 180°:

(4y -1)+(2x +5) = 180

4y -1 +2x +5 = 180

4y +2x +4 = 180

We know from the question 7 that x is 38°:

4y +2•(38) +4 = 180

4y - 76 +4 = 180

4y - 80 = 180

4y = 180 + 80

4y = 260

y = 260/4

y = 65

Finding the value of the angles:

You just have to put the value of x and y in their places and make the calculations:

4•65 +1 = 261°

3•(38) -33 = 81°

You have some candies in your pocket. A friend gives you five more candies. When you count all your candies you have 14

Answers

Answer:

9 candies

Step-by-step explanation:

You are required to find the number of candies in your pocket

Let

x = number of candies in your pocket

A friend gives you five more candies.

Total candies = 14

This can be represented by the equation:

Total candies = candies in your pocket + candies your friend gave you

14 = x + 5

14 - 5 = x

9 = x

x = 9 candies

x = number of candies in your pocket = 9

Answers

Answer:

150 degrees

Step-by-step explanation:

I think V and T add up to 180 degrees (and all angles in a whole quadrilateral add up to 360) so if you add them and make it equal 180 you can solve x.

So x + 3x + 60 = 180

4x = 120

x = 30 degrees

So V is 3(30) + 60 = 150 degrees
