Answer:

Step-by-step explanation:(a)

1.65p+1.36j=118.17 and p+j=79

We can say p=79-j and sub this value in first equation

1.65(79-j)+1.36j=118.17

130.35-1.65j+1.36j=118.17

-0.29=-12.18

j=42, p=79-j, p=79-42=37

(b)

1.65(37)=61.05 and 1.36(42)=57.12

Sanchez class earned more selling pies.

(c)

61.05-57.12=3.93

So Sanchez class made $3.93 more than Kelley class.

A bag contains 2 red, 5 blue, and 3 green marbles. A marble is chosen at random. What is the probability of NOT choosing a red m

Lapatulllka [165]

Step-by-step explanation:

Number of red = 2
Number of blue = 5
Number of green = 3

total number of marbles = 10

<h3>probability of not choosing a red marble = 1--choosing a red marble.</h3>

Because probability is always one(1).

Probability =

 $1 - \frac{2}{10}$ 

 $\frac{8}{10}$ 

 $\frac{4}{5}$ 

Is the probability of not choosing a red marble.
