1, 3, 4, 4, 4, 6, 6, 8, 9

Median: 4

Mode: 4

Mean: 5

Mean: 1 + 3 + 4 + 4 + 4 + 6 + 6 + 8 + 9 = 45/9 = 5

Write the point-slope equation for each line with the given slope and point. y –y1 = m(x – x1) Slope = 5 Point on line = (–1, 3)
snow_lady [41]

Answer:

y-3=5(x+1)

Step-by-step explanation:

Point-Slope form is: y-y_1=m(x-x_1)

'm' - Slope

(x1, y1) - Point Coordinate

We are given the point of (-1,3) and the slope of 5.

Replace 'm' with 5, 'x1' with -1, and 'y1' with 3:

y-y_1=m(x-x_1)\rightarrow\boxed{y-3=5(x+1)}

Need help understanding what to do
Juliette [100K]
I believe you are expected to simplify. To do this all you do is group like terms (x, x², x³ etc.) and then simplify the coefficients. 

13. 10z + 7z - 19z² - 5z² - 17z 

first you can rearrange and group like terms (remember the bring the sign in front of each term with it). I would do it like this: 
-19z² - 5z² +10z + 7z - 17z

Now simplify the coefficients: 

-24z² + 0z 

you can omit the 0z and your simplified answer is 

-24z²

Main thing to remember here is that z and z² cannot be simplified together, nor can any variable that has an exponent because the exponent makes them differ.

Answer:

Question 2. 12% of 650 = 78

Step-by-step explanation:

100% = 1 in decimal form.

This is because finding 100% of something is the same as multiplying it by 1:

E.g. 100% of 10=10,  10x1 = 10

Therefore to find a percentage of something, we simply need to multiply it by the decimal form of that percentage. For example, if we were finding 50% of 10 (half), 50% in decimal form is 0.5, 10x0.5 = 5

The percentage here is 12%, we can find the decimal form by dividing it by 100, 12/100 = 0.12

So, in order to find 12% of 650, we just need to multiply 650 by 0.12:

650x0.12 = 78

12% of 650 = 78

Hope this helped!
