Answer:

A = 3

B = -5

C = 2

Step-by-step explanation:

The way to format a quadratic equation is: ax^2 + bx + c, so the first step to solving this is to format it in the right way, where the x^2 comes first, the x second, and the number alone.

After formatting, your equation should look like this: 3x^2 - 5x + 2

From here, you can see the the <em>a </em> is 3, the <em>b</em> is -5, and the <em>c </em>is 2

Aron has a bag of marbles that contains three red (r) marbles, four green (g) marbles, and three blue (b) marbles. which express
pshichka [43]
We know that

red marbies=3------> r=3
green marbies=4----> g=4
blue marbies=3-----> b=3
total marbles in the bag=r+g+b-----> 3+4+3-----> 10

a) <span>probability of randomly selecting a green (g) marble
P(green)=g/total marbles------> 4/10-----> 2/5

b) </span>probability of randomly selecting a red (r) marble
the marble is replaced so we have the same total marbles
P(red)=r/total marbles------> 3/10

c) <span>Total probability of selecting this path is:
P(green)*P(red)-----> (2/5)*(3/10)-----> 6/50----> 3/25----> 0.12  (12%)

the answer is
0.12  (12%)</span>

Age of Peter + age of Pol = 39
GalinKa [24]

Answer:

PETER 18

POL 21

MARY 26

Step-by-step explanation:

I dont know if I did in the right way...

1st: Take any number for peter's or pol's age

I took 18 for peter, RANDOMLY

2nd: Subtract the age from the total to get pol's age

39-18=21 Hence, pols age is 21

3rd: Subtract peter's age from the total to get marys age

47-18=26 Hence, Marys age is 26

4th: Add the age of pol and mary

aaand, you get 47

Done!

Hope it helps!!!
