Answer:
x>-3
Step-by-step explanation:
I used a calculator
Answer:
13% chance
Step-by-step explanation:
Area of backyard = length * width
A = 30 ft * 20 ft
A = 600 
Area of bathtub = π 
A = π *
A = 78.54 
Probability of arrow landing in tub can be found by dividing Area of the bathtub by the area of the backyard, and then multiplying by 100 for a percentage
Prob. = 78.54/600
Prob. = 0.13
Prob. = 0.13 * 100
Prob. = 13%

Why?</h2>
Since we are given the margin of error and it's equal to ±0.1 feet, and we know the surveyed distance, we can calculate the maximum and minimum distance. We must remember that margin of errors usually involves and maximum and minimum margin of a measure, and it means that the real measure will not be greater or less than the values located at the margins.
We know that the surveyed distance is 1200 feet with a margin of error of ±0.1 feet, so, we can calculate the maximum and minimum distances that the reader could assume in the following way:

Answer:
The equation is not a function.
Step-by-step explanation:
We are given that


Function: It is mapping between the values of two sets A and B.
Each element of A has unique value in set B.
By definition of function
In given function
y has no unique value for each value of x.
Substitute x=0

Hence, it is not a function.
