Hiiii idk I’m so sorry I’m really dumb at math
I dont know but im a material girl with balls
Given that the function y=3.5x+2.8 represents the cost y (in dollars) of a taxi ride of x miles, and that <span>you have enough money to travel at most 20 miles.
The domain of a function is the set of possible values of x, given that the maximum number of miles you can travel is 20 miles, the domain of the function is from 0 to 20.
Domain = {x: 0 ≤ x ≤ 20}
The range of a function is the set of the possible values of the function.
For x = 0, y = 3.5(0) + 2.8 = 2.8
For x = 20, y = 3.5(20) + 2.8 = 72.8
Therefore, the range of the function is from $2.8 when no mile was covered and $72.8 when 20 miles was covered.
Therefore, range = {y: 2.8 ≤ y ≤ 72.8}

Answer:
The formula for the volume of a sphere is V = 4/3 πr³.
Step-by-step explanation:
Surface area of sphere = 4πr2
Volume of a sphere = 4/3 πr3
You only need to know the radius to figure both the volume and surface area of a sphere.
Answers for surface area problems should always be in square units.
Answers for volume problems should always be in cubic units.
Answer: The standard error of the mean = 0.5
Step-by-step explanation:
Given : Sample size : n = 144
Standard deviation : 
The formula to find the standard error of the mean is given by :-
i.e. 
Hence, the standard error of the mean =0.5
