What is a function?

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

Describe the function between x = - 4 and x = -1.

As the value of x increases the value of the function also increases.

Then the function is an increasing function between -4 to -1.

Between -4 to -1 the function is a linear function.

At Lincoln Middle School, 1/3 of the students play a musical instrument. Of the students who play instruments, 3/4 tried out for the class play. What is the probability that a student
selected at random plays a musical instrument and tried out for the class play?
25%
33%
66%
75%

Answers

it is 25% ...................

The probability that a student selected at random plays a musical instrument and tried out for the class play is 25%.

To find the probability that a student selected at random plays a musical instrument and tried out for the class play, we need to multiply the probabilities of each event happening.

Given:

Probability of a student playing a musical instrument = 1/3

Probability of a student who plays an instrument trying out for the class play = 3/4

To find the combined probability, we multiply these probabilities:

Probability = (1/3) * (3/4)

Simplifying the multiplication:

Probability = 1/4

Converting the fraction to a percentage:

Probability = 1/4 * 100% = 25%

Therefore, the probability that a student selected at random plays a musical instrument and tried out for the class play is 25%.

Simplify your answer and write it as a proper fraction, mixed number, or whole number.

Answers

Answer:

$16

Step-by-step explanation:

$4 for 1/4 of a pie, means that it isn't an entire pie. Luckily for us, this is simple multiplication. You would multiply like so:

4 x 4 = 16

And you'd get your answer, since 4/4 equals 1 whole.

The mean of 5 numbers is 11. the numbers are in the ratio 1:2:3:4:5 find the smallest number?

Answers

The smallest number is x = 11/3. The smallest number in the given ratio of 1:2:3:4:5 whose mean is 11 is 11/3.

Given that the mean of 5 numbers is 11. The numbers are in the ratio 1:2:3:4:5. We need to find the smallest number. We can start solving the problem by following these steps:

Step 1: Let us assume the smallest number to be x.

Step 2: According to the question, the numbers are in the ratio 1:2:3:4:5. Hence, the other four numbers can be written as 2x, 3x, 4x, and 5x.

Step 3: The mean of these 5 numbers is given as 11.

Therefore, we can write:(x + 2x + 3x + 4x + 5x)/5 = 11.

Step 4: Simplifying the above equation, we get:15x/5 = 11x = 11/3.

Step 5: Therefore, the smallest number is x = 11/3.

The smallest number in the given ratio of 1:2:3:4:5 whose mean is 11 is 11/3.
