The last 5 transactions at Mr. Brigham's ATM were $250, -$60, -$94, $300, and -$186. Find the mean transactions amount.
Shalnov [3]

To find the mean transaction amount. We need to understand mean first.

Mean (or average) is a number that expresses the central value in a set of data,  which is calculated by dividing the sum of the values in the set by their number of values.

Here, the transactions shown are

$250, -$60, -$94, $300, and -$186. So there are 5 transactions.

Now mean transaction amount is given by:

\frac{250+(-60)+(-94)+(300)+(-186)}{5} =\frac{250-60-94+300-186}{5}= \frac{210}{5} =42

So, the mean transaction amount over 5 transactions is $42.00.

Digiron [165]

Answer:

Step-by-step explanation:

Back

Area = L * W

L = 20

W = 8

Area = 20 * 8

Area =                                                                       160

2 Triangles

Area = 1/2 one smaller leg*other smaller leg

one smaller leg = 8

The other one = 15

Area = 1/2 8 * 15  =     60

But there are 2 of them 2 * 60 =                            120

Base

L =  20

W = 15

Area = L * W

Area = 20*15 =                                                        300

Front (slanted) Face

L = 20

W = 17

Area = L * W

Area =  20*17                                 <u>                         340</u>

Total                                                                        920

How many metres more will a car travel in 12 min at a speed of 50 km/h than it will at a speed of 40 km/h?
Zanzabum
50-40 = 10 km/h which is the speed difference.

10 km/h = 1/6 km/min

In 12 minutes, it will travel 1/6 * 12 = 2 km = 2000 metres more.
