A: the mean salary is $500.
400+500+600=1500/3=500
b: the median is $500 also.
Answer:
y=2x+8
Step-by-step explanation:
Alright so, to find the equation, we need to find the slope first. We can do that by turning the input and output into coordinates.
(1,10) and (2,12)
To find the slope, we do:

Which equals to 2
So right now we can say that the equation is:
y=2x+b
In order to find b, the constant, we just need to plug in the y values and x value of a coordinate:
10=2(1)+b
10=2+b
8=b
So now we can say that the equation is:
y=2x+8
Answer:
h(x) = -x^2 - 1
Step-by-step explanation:
well y, h(x), f(x), n(x), or any other something of x is all the same thing y.
So if f(x) is -x^2 - 1,
Then h(x) is also -x^2 - 1
Answer: A. 
Step-by-step explanation:
Given : A certain CD-ROM disk can store approximately
megabytes of information.
1 megabyte =
bytes
Then, The storage capacity of CD-ROM disk will be :
If an average word requires 14 bytes of storage, then the number of words can be stored :-

Hence, number of words can be stored =
