6. Sammi spun a spinner with 5 equal parts labeled 1-5. If she spins the spinner 20 times, how many times should she expect to spin a 2? A 4 B 3 C 8 5​

Answers

Answer 1

Answer:

Step-by-step explanation:

There is a 1/5 chance she spins a 1. (1/5 = 20% = 0.2)

She spins 20 times:

20 * 0.2 = 4

So she should expect getting 4 twos.

Answers

Answer:

4n + 1

Step-by-step explanation: The numbers are rising by 4, so this gives us 4n. Term number 1: 4n = 4, but the first number in the sequence is 5 so we have to add 1.

Term number 2: 4n = 8, but the second number in the sequence is 9 so, again, we have to add 1.

A module house is made by sticking a triangular prism on top of a rectangular block, as shown in the diagram.

Answers

Answer:

d

Step-by-step explanation:

The volume of the triangular prism.

= Base area x length of the prism

The volume of the rectangular block.

= Length x width x height

The volume of the model house is 1260 cubic feet.

Option A is the correct answer.

What is a rectangle?

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

Module house:

Triangular prism on top and a rectangular block.

The volume of the triangular prism.

= Base area x length of the prism

= (1/2 x 12 x 4) x 15

= 24 x 15

= 360 cubic feet

The volume of the rectangular block.

= Length x width x height

= 12 x 15 x 5

= 900 cubic feet

The volume of the block house.

= Volume of the triangular prism + Volume of the rectangular block

= 360 + 900

= 1260 cubic feet

Thus,

The volume of the model house is 1260 cubic feet.

Option A is the correct answer.

this is very confusing.

2x² + 2x - 4 = 2x ( x + 1 - 2 )

4x + 2x - 4

8x-4

4x = 2x ( x + 1 - 2)

8x + 2 - 2

8x + 4x

= 12x. I think 12x is the correct factor.

x = 15

Step-by-step explanation:

All angles add up to 180

so,

2x + 4x + 10 + 6x - 10 = 180

combine like terms

12x = 180

divide by 12

x = 15

check it by plugging it in

2x = 2(15) = 30

4x + 10 = 4(15) + 10 = 70

6x - 10 = 6(15) - 10 = 80

30 + 70 + 80 = 180
