Hello There!

Mean: Average of numbers in a set of data.

STEP 1: Add the numbers up. In this case, we would add

12 + 17 + 16 + 10 + 20 + 13 + 14 + 14 + 12 + 12 + 19 + 18 = 177

STEP 2: Divide the sum of the number by the number of digits you added.

We would divide 177 "sum of numbers" by 12 "number of digits" and would

get a quotient of 14.75

<u><em>The mean for this set of data is 14.75</em></u>

<u><em></em></u>

Jerome bought 15 videos from a department store. Some videos were new releases, x, which cost $19, and some videos were classics
Neporo4naja [7]

Answer:

The system of equations is

x+y=15

19x+8y=164

Step-by-step explanation:

Let

x------> the number of videos of new releases

y-----> the number of classics videos

we know that

x+y=15 ------> equation A

19x+8y=164 ------> equation B

Using a graphing tool

Solve the system of equations

Remember that the solution of the system of equations is the intersection point both graphs

The intersection point is (4,11)

see the attached figure

therefore

the number of videos of new releases is 4

the number of classics videos is 11

 PLEASE HELP!! A tennis ball machine serves a ball vertically into the air from a height of two feet, with an initial speed of 1
ch4aika [34]
Thank you for posting your question here. I hope the answer below will help. 

Vo=110 feet per second 
<span>ho=2 feet </span>
<span>So, h(t) = -16t^2 +110t +2 </span>
<span>Take the derivative: h'(t) = 110 -32t </span>
<span>The maximum height will be at the inflection when the derivative crosses the x-axis aka when h'(t)=0. </span>
<span>So, set h'(t)=0 and solve for t: </span>
<span>0 = 110 -32t </span>
<span>-110 = -32t </span>
<span>t=3.4375 </span>
<span>t=3.44 seconds </span>
