We can find the volume of one of the cubes, then multiply by 3996 to find the total volume.

The edge lengths are 1/3, so the area of one cube is:

(1/3)^3 = 1/27

The area of the prism is:

3996 * (1/27) = 148 in^3

Which sequence is geometric and has 1/4 as its fifth term and 1/2 as the common ratio?
olchik [2.2K]
5th term = a1r^4   where a1 = first term and r = common ratio

so 1/4 = a1 * (1/2)^4

a1 = 1/4 / (1/2)^4  =  4

so the sequence  is  4 , 4*1/2, 4*(1/2)^2...

= 4, 2, 1, 1/2, 1/4 .....

a number cube numbered 1-6 is rolled 30 times and lands on an even number 18 times. How does this frequency compare to the expec
Korolek [52]

Answer:

The frequency is 3 more than expected

Step-by-step explanation:

There are 3 favourable outcomes: {2, 4, 6}

There are 6 possible outcomes: {1, 2, 3, 4, 5, 6}

probability of the number cube landing on an even number = favourable outcomes / possible outcomes = 3/6 = 1/2

If the cube is rolled 30 times, it is expected that in 1/2*30 = 15 times landed on an even number. The frequency: 18 is 3 more than expected
