What is the sum of ten terms of an infinite geometric series if the first term is 8 and the ratio is 1/2
xxTIMURxx [149]

Answer:

We use the formula:

S 10 = 8 · [(1/2)^9 - 1] / (1/2 - 1 );

Then, S 10 = 8 · ( 1/512 - 1 ) / ( 1/2 - 1 );

S 10 = 8 · ( - 511 / 512 ) / (-1 / 2 );

S 10 = ( - 511 / 64 ) · ( - 2 );

S 10 = + 511 / 32;

S 10 = 15.96;

the probability that we encounter a green light at the corner of college and main is 0.35, a yellow light 0.04, and a red light
Ostrovityanka [42]

Answer:

21% probability you will hit a green light on monday and a red light on tuesday

Step-by-step explanation:

When two events, A and B, are independent, we have that:

P(A \cap B) = P(A) \times P(B)

In this problem, we have that:

Event A: Green light on monday.

Event B: Red light on tuesday.

The probability that we encounter a green light at the corner of college and main is 0.35

This means that P(A) = 0.35

The probability that we encounter a red light is 0.61:

This means that P(B) = 0.61

These events are independent, that is, the light color on Tuesday is independent of the color on Monday. So

P(A \cap B) = P(A) \times P(B) = 0.35 \times 0.6 = 0.21

21% probability you will hit a green light on monday and a red light on tuesday
