Answer:

C

Step-by-step explanation:

First we find the z-score.

z = (x - μ) / σ

z = (520 - 500) / 60

z = 0.33

Using a calculator or z-score table:

P(z < 0.33) = 0.6293

The probability is approximately 63%.  Answer C

Hi there! The answer is C.

The area of the square in the middle is the following:
length \: \times \: width \: = 5 \times 5 = 25
Hence, the area of the square is 25 cm^2.

The area of one triangle is the following:
0.5 \times base \: \times \: height \: = 0.5 \times 5 \times 8 = 20
Hence, the total area of the four triangles is 4 × 20 = 80 cm^2.

Therefore, the total area of the pyramid is 80 + 25 = 105 cm^2. The answer is C.
