The 10th grade class at Central high school was surveyed about whether they liked running or swimming. Of those surveyed, 58% sa

Answer:

24% of those surveyed liked neither

Step-by-step explanation:

Set concepts:

We use set concepts to solve this question.

I am going to say that:

P(A) is the percentage of people that liked to swim.

P(B) is the the percentage of people that liked to run.

The percentage of people that liked at least one of these activities is:

$P(A \cup B) = P(A) + P(B) - P(A \cap B)$

In which $P(A \cap B)$ is the probability that a person liked both these activities.

The percentage of people that liked neither is:

$P = 1 - P(A \cup B)$

Of those surveyed, 58% said they liked to swim and 36% said they liked to run.

This means that $P(A) = 0.58, P(B) = 0.36$

18% said they liked both swimming and running

This means that $P(A \cap B) = 0.18$

What percent of those surveyed liked neither?

At least one:

$P(A \cup B) = 0.58 + 0.36 - 0.18 = 0.76$

Neither:

$P = 1 - P(A \cup B) = 1 - 0.76 = 0.24$

24% of those surveyed liked neither

Nadya [2.5K]

In x^7•x^4, how many x’s are multiplied together? (There’s 7 in the first factor and 4 in the second.)

x^7•x^4 = x^__? This is your a-value.

Similarly, y^2•y^5 = y^__? How many y’s are there in total being multiplied? This is your b-value.
