The grams of sugar per serving for three brands of cereal are 4 g, 10 g, and 14 g. The probability of choosing a cereal with 4 g
Sergio039 [100]

Answer:

Expected\ Value = 9

Step-by-step explanation:

Given

Cereal A

Probability = \frac{1}{4}

Grams = 4

Cereal B

Probability = \frac{5}{8}

Grams = 10

Cereal C

Probability = \frac{1}{8}

Grams = 14

Required

Determine the expected value of grams of sugar

This is calculated by multiplying the probability and grams of sugar in each cereal.

The results of the products are then added together

i.e.

Expected\ Value = \frac{1}{4} * 4 + \frac{5}{8} * 10 + \frac{1}{8} * 14

Expected\ Value = 1 + \frac{50}{8}+ \frac{14}{8}

Expected\ Value = 1 + 6.25 + 1.75

Expected\ Value = 9

Hence;

The expected value of grams of sugar is 9 grams

-3j - (-4) over -6 = 12 j= ? ​
babymother [125]

Answer:

j =76/3

Step-by-step explanation:

-3j -  -4

------------------ = 12

-6

Multiply each side by -6 to clear the fraction

-3j +4

------------------ * -6 = 12 *-6

-6

-3j +4 = -72

Subtract 4 from each side

-3j +4-4 = -72 -4

-3j = -76

Divide each side by -3

-3j/-3 = -76/-3

j = 76/3
