A)Total hours she worked =8+7.5+6.5+3+9= 34 hours
b)Amount she was paid= 34 hours x $20.25= 688.50
She was paid $688.50
In this question we simple wish to calculate the standard error and margin of error from the population. This can be done purely using the standard deviation and sample size.
Standard error
= std dev / (SQRT) n
= 11.5 / SQRT of 70
= 11.5 / 8.366
= 1.374
Margin of error is the standard error multiplied by a Z value that correspondence to a confidence percentage. At a 95% confidence the Z value is 1.96. Therefore
MOE = 1.96 x 1.374 = 2.69
Answer:
80%
Step-by-step explanation:
it’s 82% but rounded its 80
The slope is given as 1.
The Y-intercept is where the line crosses the Y axis when X is 0. This is also given by the point (0,5/6). X is 0 and Y is 5/6, so the Y-intercept is 5/6.
The equation of a line is given as y = mx +b where m is the slope and b is the y-intercept.
The equation is: y = x +5/6
n = number of vehicle
C = cost
Therefore,
Just input the n values to the equation and see if you will get the resulting cost C. The equation is definitely,
C = 200n + 150
