What is the cube of 8

Mathematics

8 cubed, 8^3, is the number you get when multiplying 8 times 8 times 8. It can also be looked at as exponentiation involving the base 8 and the exponent 3.

8^3 = 512
8 x 8 x 8 = 512

Suppose task B follows task A. The likelihood that a problem will occur with task A is 0.5, and the time to correct the problem
jasenka [17]

Answer:

The risk consequence of both activities is 1.6 months.

Step-by-step explanation:

We can define a randome variable D: total delay time for the project, and calculate its expected value.

This would be the risk consequence of both activities.

The expected delay time for the project is the sum of the expected delay for task A plus the expected delay for task B. It is assumed the likelihood of a problem in any task is independent of the other.

Then, each expected delay for a task is equal to the probability of a problem multiplied by the consequence (delay time).

E(D)=E(D_a)+E(D_b)=p_aT_a+p_bT_b\\\\E(D)=0.5*2+0.2*3=1+0.6=1.6

The risk consequence of both activities is 1.6 months.

Marc was born on his grandmother’s 56th birthday. In how many years will Marcs grandmother be 5 times as Marc will be then?
sergey [27]

Answer:

<u>In 14 years Marc's grandmother will be 5 times as Marc will be then</u>

Step-by-step explanation:

1. Information given to us to solve the problem:

Marc's age today = 0

Marc's grandmother age today = 56

2. In how many years will Marc's grandmother be 5 times as Marc will be then?

x = Number of years when Marc's grandmother age will be 5 times as Marc will be then

Let's solve for x, this way:

5 times Marc age in x years = Marc's grandmother age in x years

5 (0 + x) = 56 + x

5x = 56 + x

5x - x = 56 (Subtracting x at both sides)

4x = 56

x = 56/4

<u>x = 14</u>

Let's prove that x = 14 is correct:

5 (0 + 14) = 56 + 14

70 = 70

We proved that x = 14 is correct

<u>In 14 years Marc's grandmother will be 5 times as Marc will be then</u>

Someone help me please :)
guapka [62]

Answer:

7/16 C.

Step-by-step explanation:

You need to find the common denominator which in this case is 16...it takes 8, two times to get to 16 which 1 times 2 is 2 so therefore it would 5+2 which is 7 and the common denominator stays the same so it would be 7/16. If you are still confused just private message me and I’d be happy to help if you though this was helpful please mark me as branlist thanks! HAVE A GOOD DAY!!!
