Answer:

The 3rd option

Step-by-step explanation:

Look at the data provided:

12, 17, 18, 20, 16, 10, 13, 21, 9, 10, 22

In a box-and-whisker plot, draw a box from the first quartile to the third quartile:

Q1 = 11

Q3 = 19

A vertical line goes through the box at the median:

Median (Q2): 15

The whiskers go from each quartile to the minimum or maximum:

Minimum: 9

Maximum: 22

Hope this helped :)

Let Q(x, y) be the predicate "If x < y then x2 < y2," with domain for both x and y being R, the set of all real numbers.

Levart [38]

Answer:

a) Q(-2,1) is false

b) Q(-5,2) is false

c)Q(3,8) is true

d)Q(9,10) is true

Step-by-step explanation:

Given data is $Q(x,y)$ is predicate that $x$ then $x^{2}$ . where $x,y$ are rational numbers.

a)

when $x=-2, y=1$

Here $-2$ that is $x$ satisfied. Then

$(-2)^{2}$

$4$ this is wrong. since $4>1$

That is $x^{2}$ $>y^{2}$ Thus $Q(x,y)$ $=Q(-2,1)$ is false.

b)

Assume $Q(x,y)=Q(-5,2)$ .

That is $x=-5, y=2$

Here $-5$ that is $x$ this condition is satisfied.

Then

$(-5)^{2}$

$25$ this is not true. since $25>4$ .

This is similar to the truth value of part (a).

Since in both $x$ satisfied and $x^{2} >y^{2}$ for both the points.

c)

if $Q(x,y)=Q(3,8)$ that is $x=3$ and $y=8$

Here $3$ this satisfies the condition $x$ .

Then $3^{2}$

$9$ This also satisfies the condition $x^{2}$ .

Hence $Q(3,8)$ exists and it is true.

d)

Assume $Q(x,y)=Q(9,10)$

Here $9$ satisfies the condition $x$

Then $9^{2}$

$81$ satisfies the condition $x^{2}$ .

Thus, $Q(9,10)$ point exists and it is true. This satisfies the same values as in part (c)

What is the value of x in the equation 2x+3y=36 when y=6

Lady_Fox [76]

2x+3y=36
2x=36-3y
y=6
2x=36-3*6
2x=36-18
2x=18
x=18:2
x=9

What is the area, measured in square centimeters, of the parallelogram below? Do not include units in your answer. 70cm 80cm

Likurg_2 [28]

Since you don't have the picture, I can explain how to do the problem. Then, you can select the correct answer.

To find the area of a parallelogram, you must multiply the base times the height. If you have those 2 values, just multiply them and you will be done.
