Answer:
ME = z*s /√n
Step-by-step explanation:
The margin of error is obtained as the product of the critical value of the distribution at a certain α-level and the standard error :
The critical value = Z*
The standard error = standard deviation / √sample size
Standard deviation = s
Sample size = n
Margin of Error = z * s/√n
<u>Answer:</u>
Distance = 3r
<u>Step-by-step explanation:</u>
We are to write an algebraic expression and then simplify it for the given situation:
<em>The distance traveled by a train in three hours with a constant speed of r miles per hour.</em>
We know the formula of distance linking the speed and the time.
Distance = speed × time
Substituting the given values to get:
Distance = r × 3
Distance = 3r
1.12 Divided by 3 equals 0.37
The answer would be 0.37 cents
The equation is y=-5x + 20, x being the hours that go by after 5pm.
