Answer:

A) Barnsboro Bank has more variation.

Step-by-step explanation:

Coefficient of Variation:

The coefficient of variation is given by the division of the standard deviation by the mean.

In this question:

The account balance with the highest coefficient of variation has more variation.

Barnsboro National Bank shows an average account balance of $315 with a standard deviation of $87.

So

cv = \frac{87}{315} = 0.2762

Wellington Savings and Loan shows an average account balance of $8350 with a standard deviation of $1800.

So

cv = \frac{1800}{8350} = 0.2156

Barnsboro Bank has the higher cv, so more variation, and the answer is given by option A.

We looking for distance
drek231 [11]

Answer:

240 m

Step-by-step explanation:

Figure is attached.

The distance the particle travels is the area under the v-t graph over the time interval from 0 min to 4 min.  The reason you can't just multiply velocity by time is that the velocity is changing at a constant rate over the given time interval (the line is going upward--the particls is speeding up).

What's the area under the graph?

The red outline forms a trapezoid.  The area of a trapezoid is  A=\frac{1}{2}h(b_1+b_2)  where the <em>b</em>'s are the lengths of the two parallel base and  <em>h</em>  is the height (the distance between the bases).

Reading the graph carefully (notice the scales!)...

A=\frac{1}{2}(4)(30+90)=(2)(120)=240 \text{m}
