Mean: add them all and divide by the count of numbers: 9.27
Median: middle value when sorted ascending: 10
Mode: number that occurs most often: 13

That's the first set of numbers. Now you know how to do the second! Excel can help you with this fast!

Use the quadratic formula to determine the exact solutions to the equation. 6x2+4x−3=0 Enter your answers in the boxes. x = or x
Black_prince [1.1K]
The quadratic formula is x= -b +/- √b²-4ac / 2a

In this problem,

a=6
b=4
c=-3

Now, we can plug this into the formula:

x= -4 +/- √4²-(4)(6)(-3) / (2)(6)
x= -4 +/- √16+72 / 12
x= -4 +/- √88 /12
x= -4 +/- 2√22 /12
x= -2 +/- √22 / 6

So,

x= -2 + √22 / 6
x= -2 - √22 / 6

Find the slope of the line passing through the points (8,-4) and (-7, -4).
Tju [1.3M]

Answer:

Step-by-step explanation:

slope=m=(Y2-Y1)/(X2-X1)

As given values

take,   (X1,Y1)=(-7,-4)

          (X2-Y2)=(8,8)

hence   X1=-7  ,  Y1= -4   ,  X2=8  , Y2= 8

putt the values in the above equation of slope we get ,

m=(8-(-4))/(8-(-7)

m=12/15    Ans

PLEASE HELP ASAP!!
Arada [10]
This is like the equivalent to a jar with 4 green balls and 6 white balls, where you are picking 3. (The 4 green balls signify the friends from kindergarten.) 

You want to solve the probability that the first two balls are green and the third is white. 
First draw --> 4 green out of 10 balls --> 4/10 = 2/5 

Second draw --> 3 green out of 9 balls --> 3/9 = 1/3 

Third draw --> 6 white out of 8 balls --> 6/8 = 3/4 


2/5 x 1/3 x 3/4 

= 6/60 

= 1/10 


so the answer is 1/10 (or 10%)
