If a spinner for a game is spun once, there is a 25% chance it will land on
bonufazy [111]

Answer:

Pr = 0.6

Step-by-step explanation:

Given

Let

O \to Orange

So:

P(O) = 25\% --- probability of O

n=2 --- Number of spin

Using the complement rule, the probability that a spin will not land on orange is:

P(O') = 1 - P(O)

P(O') = 1 - 25\%

Express as decimal

P(O') = 1 - 0.25

P(O') = 0.75

On two spins, the probability that it will not land on orange is:

Pr = P(O') * P(O')

So, we have:

Pr = 0.75* 0.75

Pr = 0.5625

<em></em>Pr = 0.6<em> --- approximated</em>

The formula c = 5p + 215 relates c, the total cost in dollars of hosting a birthday party at a skating rink, to p, the number of
emmasim [6.3K]

Answer: a. p = c/5 - 43        b. 17 people

Step-by-step explanation:

c= 5p + 215  

A)  a said solve for p so we will solve for p in the equation.

c= 5p + 215  First   Subtract 215 from both sides

-215     -215  

c - 215 = 5p Now divide both sides by 5.

p = c/5 - 43  

B)  If c is the total cost  of hosting a birthday party then we will input 300 into the equation for c and solve for p.

300 = 5p + 215    First subtract 215 from both sides

-215             -215

 85 = 5p      Divide both sides by 5

 p = 17  

This means  17 people can attend the meeting if Allies parents are willing to spend $300.
