If you were flipping a coin, and needed to get 2 heads in a row, what is the probability of getting two heads in a row. Use your probability tree to help. /

### Answers

**Answer:**

1/4

**Step-by-step explanation:**

If you flip it twice the possible outcomes are

H H

H T

The chances of you getting H H is 1 / 4. If you flip it more than twice, the probability changes. Let's try three times. That gives you 8 different choices.

H H H *

**Answer:**

a) 179

b) 21

**Step-by-step explanation:**

When making a Venn diagram for a problem like this, it often works well to fill in the "both" quantity first. Then that is subtracted from the number for grocery to find "grocery only", and from the number for drug store to find "drug store only." The sum of the numbers inside the circles (88+33+58) is the number who shopped at the grocery or drug store. The number who shopped at neither is the difference between this number and the total number of shoppers (200-179).

A. 25

B. 66

O c. 50

D. 33

### Answers

**Answer:**

66

**Step-by-step explanation:**

The area of a rectangle can be found with the formula 'length time width' (lw). The length is 22, and the width is 3. Multiply 3 and 22 and you get 66 as your area.

66 square units is the **area **of the given **rectangle**.

What is Area?

The **area **is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it **occupies**.

To find the **area **of a **rectangle**, we multiply its length by its width.

In this case, the length is 22 and the width is 3.

Therefore, the area of the **rectangle **is:

Area = length × width = 22 × 3 = 66 square units.

So, the **area **of the **rectangle **is 66 square units.

What is one-fifth of a number, x, increased by 24 is equal to eight tenths of the same number, x.

### Answers

**Answer:**

x = 40

**Step-by-step explanation:**

(x × [tex]\frac{1}{5}[/tex] )+ 24 = [tex]\frac{8}{10}[/tex] × x

0.2x + 24 = 0.8x

0.2x - 0.2x + 24 = 0.8x - 0.2x

24 = 0.6x

0.6x = 24

0.6x × [tex]1\frac{2}{3}[/tex] = 24 × [tex]1\frac{2}{3}[/tex]

x = 40

**Answer:**

x=40

**Step-by-step explanation:**

1/5x+24=8/10x

give like denominators

2/10x+24=8/10x

subtract 2/10x on both sides

24=6/10x

divide 24 by 6/10, or multiply by 10/6
