Answer:

The function is "f(x) = 5*x"

Step-by-step explanation:

Everytime we add a number to the independent variable of a function, in this case x, there'll be a common factor between the variable and a pure number. To solve this problem we need to make "(x + 3)" appear. Since we have "f(x+3)" we need to first factor the common denominator. We have:

f(x + 3) = 5*(x + 3)

Therefore,

f(x) = 5*x

According to the scatterplot below, which statement is correct?

Answer:

Hey there

Step-by-step explanation:

The input, or independent variable, is years in operation.

Step-by-step explanation:

In an ordered pair (x, y), the independent variable or input is x and y is the dependent variable or the output.

Therefore, the values on x-axis determine the results or output on y-axis.

The ordered pairs (x, y) are:

(1, 11) ⇒ there are 11 enrollees on Year 1

(2, 33) ⇒ there are 33 enrollees on Year 2

(3, 39) ⇒ there are 39 enrollees on Year 3

(4, 58) ⇒ there are 58 enrollees on Year 4

(5, 85) ⇒ there are 85 enrollees on Year 5

Where:

x are values on the x-axis that refers to number of years in operation

y are values on the y-axis that refers to the corresponding numbers of enrollees for each year.

Even without the graph, the correct statements i:

The input, or independent variable, is years in operation.

Alright, here goes:
For this question, you are asked about the median and Interquartile Range(IQR), so first you need to understand what that means.
The IQR is the box in the middle of the box-and-whisker-plot. The question asks for the place to have a small IQR, so the most likely places are Pensacola and Jacksonville.
The question is also asking for a high median temperature. The median is the line in the middle of the plot.
The median of Pensacola's plot is higher than the median of Jacksonville, so Pensacola Beach is your answer :)

Circle O is shown. Line segments B O and O C are radii. Point A is on the circle and is not within angle B O C.

The ratio of major to minor arc = 2 : 1

What is a Circle?

A circle is the locus of a point such that its distance from a fixed point (center) is always constant.

Calculation

The length of an arc (L) with center angle θ is given by:

L = (θ/360) * 2πr

where r is the radius.

Putting the values in the above formula.

For the major arc:

L = (240/360) * 2πr

For the major arc:

l = ((360-240)/360) * 2πr

l = (120/360) * 2πr

The ratio of major to minor arc = [(240/360) * 2πr] / [(120/360) *2πr] = 2 : 1

The ratio of major to minor arc = 2 : 1.
