A function f(x) is shown below.

f(x) = x + x + x

Write an equivalent form of f(x) in function notation that contains only one term on the right side of the equation.

Answers

Answer 1

Answer:

f(x) = 3x

Step-by-step explanation:

when adding x (the same variable) to eachother when there is nothing in front, you always assume the coefficient is 1. since there are 3 x's, (1)x+(1)x+(1)x=3x. hope this helps:)

Answer 2
It would be 0 because 0=3x and 3x=0 so the answer would be x=0

Write the equation of the line in slope-intercept form using y=mx+b​

Answers

Equation Answer: Y=2x -4

Answer:

y = 1x - 4

Step-by-step explanation:

y = mx + b where the m is the slope and the b is the y intercept of where the line goes through the y. The M is how many squares it goes up or down. Since the line goes up 1 unit by 1 unit than the slope is 1. y = 1x + b. The line crosses the y at -4 meaning the y intercept is -4. Hope this helps!

Hey I need help please. If a correlation coefficient is -0.9 what can you say about the data. Also this is a separate question but what does it mean for 2 sets of data to be positively correlated.

Answers

Answer:

Step-by-step explanation:

A correlation coefficient is a numerical measure of some type of correlation, meaning a statistical relationship between two variables. The variables may be two columns of a given data set of observations, often called a sample, or two components of a multivariate random variable with a known distribution.                          Pearson’s correlation coefficient returns a value between -1 and 1. The interpretation of the correlation coefficient is as under:

If the correlation coefficient is -1, it indicates a strong negative relationship. It implies a perfect negative relationship between the variables.

If the correlation coefficient is 0, it indicates no relationship.

If the correlation coefficient is 1, it indicates a strong positive relationship. It implies a perfect positive relationship between the variables.

A higher absolute value of the correlation coefficient indicates a stronger relationship between variables. Thus, a correlation coefficient of 0.78 indicates a stronger positive correlation as compared to a value of say 0.36. Similarly, a correlation coefficient of -0.87 indicates a stronger negative correlation as compared to a correlation coefficient of say -0.40.

Correlation Values

In other words, if the value is in the positive range, then it shows that the relationship between variables is correlated positively, and both the values decrease or increase together. On the other hand, if the value is in the negative range, then it shows that the relationship between variables is correlated negatively, and both the values will go in the opposite direction.

A gumball machine contains gumballs of five different colors: 26 red, 34 white, 15 blue, 20 green, and 5 orange. The machine dispenser randomly selects one gumball. The probability of getting a red is 13/50. What is the complement?

Answers

Step-by-step explanation:

9/50 actually

The complement of probability of getting a red is 37/50.

What is Probability?

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Given that,

A gumball machine contains gumballs of five different colors.

Red gumballs = 26

White gumballs = 34

Blue gumballs = 15

Green gumballs = 20

Orange gumballs = 5

Total gumballs = 26 + 34 + 15 + 20 + 5 = 100

The probability of getting a red is 13/50.

It's complement is probability of not getting a red, that is probability of getting any gumballs other than red.

Complement = 1 - 13/50 = 37/50

Hence the complement is 37/50.
