Answer the question

Mathematics

Naya [18.7K]4 years ago

Your answer would be x=3. You would start by combining like terms such as 5x and -7x and getting -2x. Then you would move the +5 to the other side by subtracting it from both sides. You would get -6=-2x. After that you would divide -2 on both sides and since they are both negatives, it would be a positive 3.

lysha is at a local library with her best friend. they've noticed a lot of cute boys in the library, and alysha bets that of the
Annette [7]

Using the binomial distribution, there is a 0.1201 = 12.01% probability that Alysha will win the bet.

<h3>What is the binomial distribution formula?</h3>

The formula is:

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.

For this problem, the parameters are given as follows:

n = 20, p = 0.5.

She wins the bet if there are 12 boys, hence the probability is P(X = 12), found as follows:

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

P(X = 12) = C_{20,12}.(0.5)^{12}.(0.5)^{8} = 0.1201

0.1201 = 12.01% probability that Alysha will win the bet.

Alex

Answer: The expression 13÷5 is a fraction. Here the only option that makes sense as per this expression is:

B. Each of 5 cupcakes used 13 pound of sugar. What is the total amount of sugar used?

Therefore the option B is correct

Also please note:

A fraction is a number that represents a part of a whole. It consists of a numerator and a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole.
