105% =$34.02
100% (cost without sales tax) = 34.02/1.05 =$32.40
Answer:
If she wants to face the food court, she has to turn through an angle of __225°__ anti-clockwise.
Answer:
mean; 7.55
median: 9
range: 8
mode: 10
standard deviation: 2.9 or 3
Step-by-step explanation:
Slope intercept form is y=mx+b where m is the slope and b is the y part of an intercept where x is 0. So the equation for slope (y1-y2)/(x1-x2) with y1 and y2 the y values of 2 points and x1 and x2 those points' x values, so if you would use the points (-2,0) and (0,5) (I used intercepts because they are easier, but you can use any points on the line) you would get (0-5)/(-2-0) and then 5/2 for the slope. plugging in then you get y=5/2*x+5
To find the average: the sum of the values/number of values
=250+310+275+195/4
=257.5
