On Tuesday, Jennifer will mix Crunchy Grain cereal
miv72 [106K]

Answer:

there are 1/4 cups of Super Grain Cereal in the mixture

Explanation:

Super Grain cereal provides 240 calories per cup. Thus, for s cups of Super Grain cereal, there will be 240s calories

Crunchy Grain cereal provides 210 calories per 3/4 cups. Thus, 210 ÷ 3/4 per cup.

210 ÷ 3/4 = 280 calories, For c cups of Crunchy Grain cereal, there will be 280c calories

Jennifer mixes c cups of Crunchy Grain cereal, having 280 calories and s cups of Super Grain cereal, having 240 calories to get a final 1 cup mixture containing 270 calories, which can be expressed mathematically as:

280c + 240s = 270 ------- eqn(1)

Since, s cups of Super Grain cereal and c cups of Crunchy Grain cereal equals 1 cup, of the final mixture

c + s = 1 ------- eqn(2)

from eqn(2),

c = 1 - s

substitute c = 1 - s into eqn(1)

280(1 - s) + 240s = 270

280 - 280s + 240s = 270

- 40s = 270 - 280

-40s = -10

s = (-10)/(-40)

s = 1/4

Therefore, there are 1/4 cups of Super Grain Cereal in the mixture

Hugo plans to buy packs of baseball cards until he gets the card of his favorite player, but he only has enough money to buy at
netineya [11]

Considering the given discrete probability distribution, it is found that there is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.

<h3>What is the discrete probability distribution?</h3>

Researching on the internet, it is found that the discrete probability distribution for the number of packs that Hugo buys is given by:

  • P(X = 1) = 0.2.
  • P(X = 2) = 0.16.
  • P(X = 3) = 0.128.
  • P(X = 4) = 0.512.

The probability that he buys fewer than 3 packs is given by:

P(X < 3) = P(X = 1) + P(X = 2).

Hence:

P(X < 3) = P(X = 1) + P(X = 2) = 0.2 + 0.16 = 0.36.

There is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.
