One important thing to note when dealing with probability problems is to look for the words 'or' or 'and'. If you encountered 'or', you'll have to add the probabilities. If you encounter 'and', you'll have to multiply them.

In this problem, you'll have to add the probability for the males and the probability for the smokers. Thus,

Probabilty = 22 + 57 = 79%

Compare these two functions. Which<br> has the greater rate of change?<br> y= -6x + 7
Diano4ka-milaya [45]

Answer:

y = -6x + 7 has greater rate of change

Step-by-step explanation:

for the first one, the rate of change is -6x and for the second one, the rate of change is -5x so the rate of change for y = -6x + 7 is greater.

Use the formula y2 - y1 / x2 - x1 to find the slop for the  second equation. the second equation is y = -5x

A square and a rectangle have the same perimeter. The rectangle is 13 cm long and 7 cm wide.
lorasvet [3.4K]

<u>Solving</u>

Knowing that we have the information needed we will first find the perimeter of the rectangle.

Rectangle:
Length: 13cm

Width: 7cm  

Formula: L+L+W+W

13+13+7+7 = 40cm

Meaning the perimeter is 40cm and we can use this to find the length of a square. From general knowledge we know that all sides of a square is equal.

So if we divide the 4 sides by 40 we will get our answer.

40 ÷ 4 = 10

So B would be our answer...

<u>Statement</u>

<u />

Therefore the length of a side of the square is 10cm, meaning answer B is correct.

Please solve for x. (-:<br><br> Also please show me a step-by-step, thanks! uwu
Stells [14]

Answer:

x=27

Step-by-step explanation:

we know that

(3x+9)^o+90^o=180^o ----> by supplementary angles (form a linear pair)

Solve for x

Combine like terms

(3x+99)^o=180^o

subtract 99 both sides

3x=180-99\\3x=81

Divide by 3 both sides

x=27

Find the area of the regular decagon if the apothem is 2.8ft and a side is 1.8ft
geniusboy [140]
DECA=10, decagon = 10 sides.

since each side is 1.8 long, all 10 sides will be 10*1.8 or 18 units long, so that'd be the perimeter then,

\bf \textit{area of a regular polygon}\\\\&#10;A=\cfrac{1}{2}ap~~&#10;\begin{cases}&#10;a=apothem\\&#10;p=perimeter\\&#10;------\\&#10;a=2.8\\&#10;p=18&#10;\end{cases}\implies A=\cfrac{1}{2}(2.8)(18)
