mario62 [17]

Answer:

D. 47 square units

Step-by-step explanation:

The area of the piece of red paper after the hole for the photograph has been cut is the difference between the area of large square and are of small square.

<u>Area of large square:</u>

The length of the side of large square is

EF=|-4-4|=8\ units

Area of large square =8^2=64\ un^2.

<u>Area of small square:</u>

The length of the side of large square is

AB=\sqrt{(-3-(-2))^2+(-2-2)^2}=\sqrt{(-1)^2+(-4)^2}=\sqrt{1+16}=\sqrt{17}\ units

Area of small square =\sqrt{17}^2=17\ un^2.

<u>Difference:</u>

64 \ un^2-17\ un^2=47\ un^2

natali 33 [55]

Answer:

Incorrect.

Step-by-step explanation:

1 toss could not change the frequency by such a large margin 0.47 ---> 0.55.

The number of heads obtained in 30 tosses = 30 * 0.47 =  14.

So if the next toss came up heads the relative frequency of heads would be

15/31 = 0.48.
