shusha [124]3 years ago
4 0

Answer:

1. and III.

Step-by-step explanation:

Option 1 and 3 are correct.

The probability of landing on heads would be 1/2, so 50 times in 100. This is the expected outcome, so option 1 is correct.

However, that is just the most probable outcome, probability is almost never 100% accurate. Therefore, the number of heads will most likely be 50, give or take 5 or so. Therefore, option 3 is also correct.

Answer:

3.

volume \ of \ cone = \frac{1}{3}\pi r^2h  = \frac{1}{3}*3.14*6*6*15 = 3.14*36*5 = 565.2cm^3

4.

volume \ of \ cone = \frac{1}{3}\pi r^2 h = \frac{1}{3} *3.14* 12*12*20 = 3.14*12*4*20 = 3014.4cm^3

5.

volume \ of \ sphere = \frac{4}{3} \pi r^3 = \frac{4}{3}*3.14 * 3*3*3* = 4*3.14*9 = 113.0cm^3

6.

diameter = 13cm\\\\radius = 6.5cm\\\\volume \ of \ sphere = \frac{4}{3} \pi r^3= \frac{4}{3} *3.14*6.5*6.5*6.5 = 1149.8cm^3
