What is the area, in square centimeters, of the trapezoid below?<br> 11.7 cm<br> 5.5 cm<br> 6.5 cm

Mrrafil [7]

Answer:

50.05 cm^2

Step-by-step explanation:

Ok so first lets find the area of the rectangle before finding the attached triangle. You have to imagine a line separating this shape into a triangle and rectangle.

The rectangle's size is 6.5x5.5=35.75 cm^2

The rectangle's size is 11.7-6.5 to get the base length, which is 5.2

The height is 5.5

So it's 5.2*5.5/2=14.3 cm^2

14.3+35.75=50.05 cm^2

Answer:

0.4394

Step-by-step explanation:

given that an auto parts store is examining how many items were purchased per transaction at the store as compared to their online website

The data is shown below:

Frequency Frequency*Midpt

Midpt Online Total Online Total

1-3 2 40 147 80 294

4-6 5 60 103 300 515

7-9 8 15 32 120 256

10-12 11 5 18 55 198

120 300 555 1263

Thus we find total items purchased on line = 555

and total items overall purchased = 1263

Hence the probability that a randomly selected item was purchased online

= $\frac{555}{1263} \\=0.4394$
