The answer is 73.5. Just add all the numbers and divided by how many numbers there are. So you would add all the numbers and then divided by 6 since there are 6 numbers.

Answer:

73.5

Step-by-step explanation:

To find the mean, sum the data and divide by the amount of data

mean = \frac{77+82+87+85+32+78}{6}

          = \frac{441}{6} = 73.5

I need help finding M and B please

Hey there!
In our slope-intercept equation, b is the y-intercept, where the line crosses the y-axis. In our case, that happens to be -5, because that's where the line intersects the axis.
Now, we're finding m, or the slope. The slope is defined as rise over run. We can use our slope given two points formula, y2-y1/x2-x1 to find the slope.
For our two points, we'll use the intercept: (0,-5) and the other intercept: (6,0)
Let's plug in our values:
0-(-5)/6-0 =
5/6
Therefore, 5/6 is the slope.
Hope this helps!

Find the sum or difference 5/6 + 4/9
Naily [24]
The closest option to the actual answer is a.

1 5/18 is the actual answer.

If you make both the denominators the same, then you can actually add the fractions together.

To make both of the denominators the same, you need to multiply 5/6 by 9 and 4/9 by 6, which would result in 45/54 + 24/54= 69/54 = 23/18. If we convert it to a mixed fraction, it would result into 1 5/18.

How do you do <br> (2/3) (-4) (9)
DochEvi [55]

Answer:

Since 3 is evenly divided by 9, we can multiply just one term to get a common denominator. Multiply 2 by 3, and get 6, then we multiply 3 by 3 and get 9.

Y=6<br> X+2y=16<br><br> Can someone one help me out its a substitution and system of equations graph
Nikitich [7]
If you know that y = 6. You just have to switch Y by 6.

x + 2y = 16
x + 2*6 = 16
x + 12 = 16
x = 16 - 12
x= 4

4 + 2*6 = 16

Hope this helps !
