Answer:
A function is a function that passes the vertical line test
Step-by-step explanation:
the vertical line test direction:
draw a line straight down you graph if it hits the x axis two time it not a function
Answer:
-5100
Step-by-step explanation:
i just took the test
First of all, we have to draw the line. To draw a line, we only need two points. To sample to points, we choose two arbitrary x values, and compute the correspondent y values.
We may choose x=0 and x=3 to make computation/drawing easier. We have
So, this line passes through the points (0, -6) and (3, -5). Draw these two points and connect them: you have the line
Now, to solve the inequality
recall that smaller values for y means "below" in the coordinate axes. So, every point that lies below the line is a solution to the inequality.
Answer:
1.32%
Step-by-step explanation:
First, find the z-score:
z = (x − μ) / σ
z = (133 − 100) / 15
z = 2.2
Use a calculator or z-score table to find the probability.
P(x > 2.2) = 1 − 0.9868
P(x > 2.2) = 0.0132
1.32% of the population has an IQ more than 133.
To find the percentage of any number you divide your percentage by 100 to get a decimal. 14 ÷ 100 =0.14 then in this case you need to find the number you want to find 14% of . Each reindeer harness is 17.95 so 17.95 * 9 = 161.55 so now you take 161.55 and multiply it by the decimal to get the percentage of 161.55 which equals 22.617 so now add the tax and the cost of the reindeer harnesses and you got your answer :)
