Answer:

Step-by-step explanation:

65, 66, 72, 76, 78, 79, 85, 86, 90, 98

Q1 = 72

Q2 (median) = (78 + 79) / 2 = 78.5

Q3 = 86

min = 65

max = 98

so ur box plot is gonna look like this :

the box will start at 72 and end at 86......there sill be a line drawn vertically thru the box at 78.5. U will have arrows coming out of both ends of ur box....the one going left will stop at 65 and the one going right will stop at 98.

Tems11 [23]

Answer:

(-7,-4)

Step-by-step explanation:

There are 2 different ways to solve a system of equations and the one I'm going to show you will work for all systems.  To start we will solve one of the equations for either X or Y it doesn't matter which one so I will choose the second one.  Divide both sides by negative 4 and you will have the solved equation.  x=1+2y Now we know what x equals so we can plug "1+2y" into the other equation where we see an X and we will get -8(1+2y)=24-8y and since we only have one variable now we can solve to get what Y is.  The first step is distributing -8-16y=24-8y now lets put the Y's together on one side and the numbers together on the other -32=8y and just divide both sides by 8 to get the value of Y -4=y  Now that we have Y we can plug -4 into either equation as Y to get the value of X I will use the second equation.  -4x=-4-8(-4) and solve for X -4x=-4+32  -4x=28  x=-7 So now we have x and y and we can write it as out solution (-7, -4)

I hope this helps and please don't hesitate to ask if there is anything still unclear!

Answer:

c. Rational

because → whole numbers are positive and Starts from 0 so not whole number

Integers can be negative and positive

Examples of numbers that are not integers are: -1.43, 1 3/4, 3.14, . 09, and 5,643.1.

Irrational number that cannot be written in p/q

but -2.4 written in p/q = -24/100

<h3>so c. Rational Number is correct</h3>
