PSYCHO15rus [73]

Answer:

5

Step-by-step explanation:

44.75 - 28.50 = 16.25 so 16.25 divided by 3.25 equals 5 and 5 times 3.25 equals 16.25 and 16.25 plus 28.50 equals 44.75 so she bought 5 cards.

The Therrell High Marching Band is selling candy bars for a fundraiser.
igor_vitrenko [27]

Answer:

3x ≥ 45

15, 20 , 25

Step-by-step explanation:

Let's call the number of bars Renee sold as " x "

Let's call the number of bars Robin sold as " y "

Robins, y, sold two times as many bars as Renee, x

That means Robin sold 2 times x or 2x

So y = 2x

The sum of bars Renee, x,  and Robin, 2x, sold together are no less than 45

No less than 45 means the number of bars have to be greater than or equal to 45

x + 2x ≥ 45

3x ≥ 45

x ≥ 15

Renee can sell, 15, 20, or 25 bars .   (just has to be bigger or equal to 15)

If my answer is incorrect, pls correct me!

Determine the probability of selecting a two-child family with one boy and one girl assuming boys and girls are equally likely
Fittoniya [83]

Using the binomial distribution, it is found that there is a 0.5 = 50% probability of selecting a two-child family with one boy and one girl.

For each child, there are only two possible outcomes, either it is a boy, or it is a girl. The probability of a child being a boy or being a girl is independent of any other child, which means that the binomial distribution is used to solve this question.

Binomial probability distribution

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

C_{n,x} = \frac{n!}{x!(n-x)!}

The parameters are:

  • x is the number of successes.
  • n is the number of trials.
  • p is the probability of a success on a single trial.

In this problem:

  • Two children, hence n = 2.
  • Equally as likely to be a boy or a girl, hence p = 0.5.

The probability of one of each is P(X = 1), hence:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 1) = C_{2,1}.(0.5)^{1}.(0.5)^{1} = 0.5

0.5 = 50% probability of selecting a two-child family with one boy and one girl.
