This picture is a reference... The median is the middle number in the set
Q1 is the Upper quartile. You get the first quartile by taking the first half of the set of numbers. You then look and see which one is the one in the middle of that set. That's your Upper quartile.
This apples for the Q2 too. Except you're taking the last set of numbers and finding the middle of that set. This is your upper quartile.
The minimum is the first number in the set.
The maximum is the last number in the set.
Then what you're going to do is order them on the number line by putting the median on first then plot the upper and lower quartile on. Then draw a box around the Q1 and Q2. Now plot the min and max in the number line and draw lines from the box to the min and max. There you go!

Answer:

f(-2) = 4

Step-by-step explanation:

The function has three definitions depending on the value of x.

You are looking for the value of the function at x = -2.

-2 is in the interval x <= -1, which is the first line of the definition of the function.

We use the first line of the definition of the function.

f(x) = -2x for x <= -1

f(-2) = -2(-2) = 4

Answer: f(-2) = 4

A jar contains 18 apple lollipops, 7 strawberry lollipops, and 10 grape lollipops. Irvin randomly selects a lollipop, gives it t

andrey2020 [161]

First choice is "1 of 10 grape lollipops from 35 lollipops"
The probablity is 10/35 = 2/7
Second choice is "1 of 18 apple lollipops from 34 lollipops"
So probablity is 18/34 = 9/17
Between this is AND so you have to these probablities multiply:
P(A) = 2/7 * 9/17 = 18/119
P(A) = 18/119 * 100% = 1800/119 %
It is approximaly 15,1 %.
