A)The outlier if the data is 28 because it is 30+ numbers away from the next number. B) The mean for this data is 67.45. C) it would be 71.4 without the outlier. P.S to find the mean you add all the numbers together and then divide it by however many numbers there are. Hope this helps
Answer: 7 7/10
Step-by-step explanation:
First you have to multiply 1 1/5 by two so that you could subtract it from 8 9/10. Once you do that that’s when you get 7 7/10.
Answer:
D) Acceleration is positive and increasing.
Step-by-step explanation:
In formulae, acceleration is defined as the rate of change of velocity per unit time; for example:

where Δ V is the variation of velocity and Δ T is the variation in time.
The graph depicts the velocity of a moving item as a function of time. As we can see ΔV is the increment on the y-axis, while ΔT is the increment on the x axis: therefore, the ratio ΔV/ΔT is the curve's slope. In fact, the slope of the curve in a velocity-time graph corresponds to the object's acceleration. In this graph, we can see that the slope of the curve is growing, which means that the acceleration is positive (since the slope is positive and the velocity is increasing) and increasing (because the slope is increasing).
Answer:
looks like 9.5, but kinda hard to tell
