Unbiased. If it was biased then she would only choose people she wanted to answer her survey. It is unbiased because she is asking the first 10 random people who walk into her shop.

This is biased because she is asking the first morning costumers which means that the morning costumers have a greater chance of adding coffee to the menu

What is the range of the cubic function f(x)=x^3-15

Nina [5.8K]

B

The end behavior of a positive cubic function states that as x approaches infinity, y approaches infinity.

Similarly, as x approaches negative infinity, y approaches negative infinity.

This means that when written in interval notation, the range is (-inf, +inf).

I NEED HELP ON DOING THIS

stira [4]

If all the angles add up to 90 degrees then you can set the equation 7x-9*2x=90
Simplify
9x-9=90
Plus 9 both sides
9x=99
Divide by 9 on both sides
X=11

I WILL GIVE BRAINLIEST TO WHOEVER ANSWERS FIRST! A circle has a diameter AB, and its center is at (-3, 3). Point A is at (1/2,6)

kow [346]

Using the mid-point concept, it is found that point B is located at coordinates (-6.5, 0).

<h3>What is the midpoint concept?</h3>

The midpoint between two points is the halfway point between them, and is found using the mean of the coordinates.

The center is the midpoint of the two coordinates of the diameter, hence:

$C = \frac{B + A}{2}$

For the x-coordinate:

$-3 = \frac{x + 0.5}{2}$

x + 0.5 = -6

x = -6.5

For the y-coordinate:

$3 = \frac{y + 6}{2}$

y + 6 = 6

y = 0

What is the slope of the line shown?

Darya [45]

Answer:

slope = 1/2

Step-by-step explanation:

Pick two convenient integer coordinates

I'll use (0,-1) and (2,0)

slope = (y1-y2)/(x1-x2) = (-1-0) / ( 0-2) = 1/2
