I recommend photomath, it helps with all equations!
Answer:
-2/3
Step-by-step explanation:
The value of the function at x = -1 is 5
<h3>What is function?</h3>
Function can be defined as an expression, rule, or law that defines a relationship between one variable known as the independent variable and another called the dependent variable.
From the information given, we have that;
f (x) = 3 (2)x with x=-1
Now, let's substitute the value of x as - 1 in the function given;
f (x) = 3 (2)x
f (x) = 3 (2) -1
Expand the bracket;
f (x) = 6 - 1
f(x) = 5
Thus, the value of the function at x = -1 is 5

#SPJ1
A. Mean
Mean = Total / How many numbers there are
City A- Add all the numbers:
4 + 3.5 + 5 + 5.5 + 4 + 2 = 24
There are 6 numbers.
24 / 6 = 4
Mean = 4 for City A
City B- Mean:
Add all the numbers:
5 + 6 + 3.5 + 5.5 + 4 + 6 = 30
There are 6 numbers.
30 / 6 = 5
Mean = 5 for City B
B. MAD(Don't know this part)
C. Median
City A- Median:
There are 2 middle numbers.
They are 5 and 5.5
5 + 5.5 = 10.5
10.5 / 2 = 5.25
Median = 5.25 for City A
City B- Median:
The 2 middle numbers are 3.5 and 5.5
3.5 + 5.5 = 9
9 / 2 = 4.5
Median = 4.5 for City B.
Answers:
a. The mean for City A is 4. The median for City B is 5.
b. Don't know MAD
c. The median for City A is 5.25. The median for City B is 4.5
Hope this helped☺☺
