Answer:
The input (domain) are usually on the left side of the circle.
Domain = [-2, 0, 3, 4, 6]
The output (range) are usually on the right side of the circle.

Since the domain of 3 is pointing at two ranges (3, 4) and (3, -3), the x value repeats.
Functions do not have repeating x values.
The picture shown is not a function.

Step-by-step explanation:
The expected value is 
, where n=148 is the sample size and 
.
We calculate the z-score of 37.5 using the formula:
From the standard normal distribution table, the area to the left of 1.43 is 0.9236.
.
The expected number of people in the sample with body temperatures above 37.5 degrees is 
We don't have a fractional human being, so the rule of thumb is to round up.
Answer:
two numbers are 29 and 17
Step-by-step explanation:
let the number be x
12+x+x=46
2x=46-12
x=34/2
x=17
another number is 12+x
12+17
29
