Mathematics

#1,4 are biased because the number range is too wide. (include #2 if the question allows)
#1: 31-20 = 11
#2: 29-21 = 8
#3: 30-23 = 7
#4: 50-15 = 35 (OMG that's so biased!)

so if the three surveys are eliminated, then the answer to the second question is 23%.

Hope that helps :)

Answer:

Options (1), (3), (5) and (6)

Step-by-step explanation:

Option (1)

Both the circles M and H are same in shape. Therefore, both are similar.

True

Option (2)

MH = MS = [Radii of a circle]

MH = MO + OH

MH = ME + OH [Since, MO = ME]

MH = 10 + 25 = 35 cm

Area of circle M = πr²

                          = π(35)²

                          = 1225π

Area of circle H = π(25)²

                           = 625π

\frac{\text{Area of M}}{\text{Area of H}}=\frac{1225\pi }{625\pi }

Area of M = 1.96(Area of H)

False

Option 3

OH + MS = 25 + 35

               = 60 cm

True

Option 4

m∠HMS = 90°

Can't be figured out with the given informations

False

Option 5

Diameter of circle H = 2(radius)

                                 = 2(25)

                                 = 50 cm

True

Option 6

Circumference of circle S = 2πr

                                           = 2π(ES)

Circumference of circle M = 2π(MS)

Ratio of the circumference of circle S and M = \frac{2\pi (ES)}{2\pi (MS)}

                                                                          = \frac{ES}{MS}

True.

Options (1), (3), (5) and (6) are correct.
