Answer:

Convenience

Step-by-step explanation:

The convenience sampling method is defined as the non probability sampling method in the sample of the survey is taken from such a group that is easy to reach or contact. Here the sample is taken from the people that are close to hand. It is useful for the pilot testing.

In the context, the magazine publishers asks the sample of people to call and inform about their views on the amount of the advertisements in the present issues. The sample taken will be easy to reach and easy to contact. This type of sampling taken is called the convenience sampling.

Answer:

C

Step-by-step explanation:

Because of all the variables in the side lengths, we don't have enough information to use side-angle-side similarity.

We do have two angles of one triangle congruent to two corresponding angles of the other triangle, so we can use angle-angle similarity.

Sides AE and AD are corresponding sides. Sides AC and AB are corresponding.

Answer:

$42

Step-by-step explanation:

Let the amounts received by Penny, Amjit and James be 3x, 6x and 4x respectively.

According to the given information:

Amount received by Amjit = Amount received by James + 28

So,

6x = 4x + 28

6x - 4x = 28

2x = 28

x = 28/2

x = 14

Amount of money received by Penny = 3x = 3*14 = $42

By using the expression to approximate the radius of a circle, we want to compare the radius of the two pools. We will find that the radius of the full-sized pool is 2 times larger than the radius of the kiddie pool.

The expression for the radius of a circle is:

R = √(A/3)

Where A is the area of said circle.

The circular kiddie swimming pool has an area of 28ft^2, we just replace that in the above expression to get:

R =  √(28 ft^2/3) = 3 ft

The full-sized pool has an area of 113 ft^2, then its radius is:

R' = √(113 ft^2/3) = 6 ft

To see how much greater is the radius of the full-sized pool than the radius of the kiddie pool, we just take the quotient:

R'/R = 6ft/3ft = 2

Meaning that the radius of the full-sized pool is 2 times larger than the radius of the kiddie pool.

Answer:

9

Step-by-step explanation:

11 - 2 = 9

Since the internal angle sum of a triangle is 180 degrees, and the angles are in ratio if 1:1:4, the angles with that's corresponding to the 1 will have value of 180/6=30 degrees.

The largest angle will have value 30*4=120 degrees.

This is an obtuse triangle because largest angle>90 degrees.

Answer:

- 62

Step-by-step explanation:

Calculate the sums within the brackets first and then multiplication, as stated by the BOMDAS rule.

B = Brackets

O = ?

M = Multiplication

D = Division

A = Addition

S = Substitution

(- 6 + 4) = -2

(5 + 9) = 14

- 2 × 14 = -28

- 28 - 3 = - 31

2 × - 31 = - 62

Answer:

48048

Step-by-step explanation:

Total number of players = 16

Selection to be made :

1 goalie ; 10 players

Hence ;

Choosing 1 goalie from 16 players :

16C1

Choosing 10 players from the remaining (16 - 1), 15 players

15C10

Hence,

16C1 * 15C10

16 * 3003

Answer:

3 = ?

Step-by-step explanation:

The triangles are similar, so we  can use ratios

15           12 -2

------   = --------------

15+?          12

15           10

------   = --------------

15+?          12

Using cross products

15 * 12 = 10 ( 15+?)

180 = 10 ( 15+?)

Divide each side by 10

18 = 15+?

Subtract 15 from each side

18-15 = 15+?-15

Answer:

So, The possible values of h and r are

1. r = 3 , h = 3

2. r = 1, h = 27

3. r = 2, h = 6.75

Step-by-step explanation:

P.S - The exact ques is -

As we know that Volume of cone , V = [tex]\frac{1}{3}\pi r^{2}h[/tex]

As given,

V = [tex]9\pi[/tex]

⇒[tex]\frac{1}{3}\pi r^{2}h = 9\pi \\ \frac{1}{3} r^{2}h = 9 \\r^{2}h = 27[/tex]

So,

The possible values of h and r are

1. r = 3 , h = 3

2. r = 1, h = 27

3. r = 2, h = 6.75

In Case I-

When r = 3, h = 3

(3)² ×3 = 9×3 = 27

Satisfied

Case II-

r = 1, h = 27

(1)²×27 = 1×27 = 27

Satisfied

Case III-

r = 2, h = 6.75

(2)²×6.75 = 4×6.75 = 27

Satisfied

If the radius of the base of the cone is 2 inches then the height of the cone should be 2.1485 inches.

The volume of the cone is the volume occupied by the cone. It is given by the formula,

[tex]\text{Volume of the cone}= \dfrac{1}{3} \pi r^2h[/tex]

where r is the radius of the base, and h is the height of the cone.

Now, as it is given that cones need to hold 9 cubic inches of popcorn. therefore, the volume of the cone can be written as,

[tex]\text{Volume of the cone}= \dfrac{1}{3} \pi r^2h\\\\9 \times 3 = \pi r^2h\\\\\dfrac{9 \times 3}{\pi}=r^2 h\\\\8.5943 = r^2 h[/tex]

Thus, the product of the square of the radius and the height of the cone should be such that the result is 8.5943.

Now, let the radius of the cone be 2 inches, therefore, the height of the cone is,

[tex]8.5943 = r^2 h\\\\8.5943 = (2^2) h\\\\h = 2.1485\rm\ in[/tex]

Hence, if the radius of the base of the cone is 2 inches then the height of the cone should be 2.1485 inches.
