Answer:
0.9
Step-by-step explanation:
-2.5 + 5.2 + 1.7 + -0.8 = 3.6
Divide by the total count of numbers
= 0.9
Hope this helps!
Answer:
0.9
Step-by-step explanation:
To find the average or mean, you have to add up all the given numbers in your data set, then divide by how many numbers there are.
1. Add up -2.5 + 5.2 + 1.7 + (-0.8)=
(negative times positive equals negative)
simplify the signs
simplified answer= -2.5+5.2+1.7-0.8
Which equals
3.62. divide by how many numbers there are
So take 3.6 and divide it by 4.
why the number 4?
well, there are 4 numbers in the data set. so when you calculate the average, the formula would be to add up all the numbers in the data set and divide by how many numbers are in the data set and there are 4 numbers in the data set.
So... 3.6 divided by 4
is...
0.9The average is 0.9
2. If the raffle has 200 tickets total, then

Let f(x) = x + 1 and g(x) = 1/x The graph of (fog)(x) is shown below. What is the range of (fog)(x)?
Answer:
Range is [tex]\{y|y\neq 1\}[/tex]
Step-by-step explanation:
[tex]f(x)=x+1\\g(x)=\frac{1}{x}\\ \\(f\circ g)(x)=f(g(x))=f(\frac{1}{x})=\frac{1}{x}+1[/tex]
Thus, the range of the composite function is [tex]\{y|y\neq 1\}[/tex], indicated by the horizontal asymptote.
you take out a mortgage for 350,000$ at 4% compounded monthly your payment is 1671$ write a recursive formula
Answer:
Not sure if this is right but it might be something like
350,000-4%+1671m
or
3500,000-4%y/1671m
Step-by-step explanation:
The numbers we know are 350,000 4% and 1671 per month
350,000 is the full mortgage
4% is the APR or annual percentage rate like interest
and we know the monthly for the mortgage is 1671 per month
