It is very easy. To find the experimental probability of each, you have to divide the number for each color by 1000. Then, multiply it by 20 to find the amount expected out of 20.

Blue: 307 / 1000 = 0.0307 0.0307 × 20 = 6.14

Green: 642 / 1000 = 0.642 0.642 × 20 = 12.84

Yellow: 51 / 1000 = 0.051 0.051 × 20 = 1.02

Blue

P(blue) = 307 / 1000 = 0.307

Green

P(Green) = 642/1000 = 0.642

Yellow

P(Yellow) = 51/1000 = 0.051

To make the denominator 20, you are going to have to divide both numerator and denominator by 50. 1000/50 = 20

Blue= 307/50 = 6.14; P(blue) 6.14/20

Green = 642/50 = 12.84; P(blue) = 12.84 / 20

Yellow = 51/50 = 1.02; P(yellow) = 1.02/20

Check

Add these three together

1.02 + 12.84 + 6.14 = 20 as it should.

andrew11 [14]

Answer:

Question 1: 15 cups

20% (pineapple juice) = 3 cups, 100/20=5, 5*3 = 15 cups

Question 2: 20 cups

25% (orange juice) + 5% = 30%

30% (orange juice) = 6 cups, 30/6=5%, 100/5=20

I can't explain the whole thing very clearly, but hope it helped

Solve the quadratic function using square root X+10x+25 =18

lawyer [7]

Answer:

= − 7 /1 1 in fraction form

Step-by-step explanation:

STEP 1: Multiply by 1

1 + 1 0 + 2 5 = 1 8

+ 1 0 + 2 5 = 1 8 STEP 2: Combine like terms

+ 1 0 + 2 5 = 1 8

1 1 + 2 5 = 1 8 STEP 3: Subtract 2 5 from both sides of the equation

11x+25=18

1 1 + 2 5 − 2 5 = 1 8 − 2 5

STEP 4: Simplify by subtracting the numbers

1 1 + 2 5 − 2 5 = 1 8 − 2 5

11x+25−25=18−25 1 1 = 1 8 − 2 5 1 1 = -7

STEP 5: Divide both sides of the equation by the same term 1 1 = − 7 11x/ 11x = −7/ 1 1 (set up as a fraction) STEP 6: Cancel terms that are in both the numerator and denominator

= − 7 /1 1 SOLUTION

= − 7 /1 1
