Answer:

340

Step-by-step explanation:

There are a total of 100+100 = 200 people surveyed over the 2 days.

There were 38+42 = 80 people who prefer mysteries.  This means 80/200 prefer mysteries.

This tells us that out of 850 customers,

80/200(850) = 68000/200 = 340 will probably purchase mystery books.

Answer:

The area of the shaded region is 148.04 cm².

Step-by-step explanation:

It is provided that a 7 cm × 5 cm rectangle is inside a circle with radius 6 cm.

The sides of the rectangle are:

l = 7 cm

b = 6 cm.

The radius of the circle is, r = 6 cm.

Compute the area of the shaded region as follows:

Area of the shaded region = Area of rectangle - Area of circle

                                            =[\text{l}\times\text{b}]-[\pi\test{r}^{2}]\\\\=[7\times5]+[3.14\times 6\times 6]\\\\=35+113.04\\\\=148.04

Thus, the area of the shaded region is 148.04 cm².
