Answer:
C and B
C because there are 3 parts of the expression
B because a term is anything (number or variable or both) that is separated with a + or - sign
The population in Cuba is expected to grow at a rate of 4% each year . Now is
<span>1.3million .
</span>This means that after 1 year the population in Cuba would be: 1.3 million+ 4%*1.3million=1.300.000+52.000=1.352.000
After the second year the population would be: 1.352.000 + 4% of 1.352.000=...
<span>After n years the population would be: population in the n-1 th year + 4% (population in the year n-1)
</span>In 10 years the population in Cuba would be: population in the 9-th year +4% from the population in the 9-th year
The probabilities of at least 10 are repairable is 1/3. and probabilities of from 3 to 8 are repairable is 1/5*8/15 and probabilities of exactly 5 are repairable is 1/3.
According to the statement
we have given that If 15 actuators have failed and we have to find the probabilities on some conditions.
we know that the formula of probabilities is
probability = possible outcomes / total outcomes
So,
- at least 10 are repairable = 1 - (10 are not repairable)
at least 10 are repairable = 1 - 10/15
at least 10 are repairable = (15 - 10)/15
at least 10 are repairable = (5)/15
at least 10 are repairable = 1/3
- from 3 to 8 are repairable = 3/15 *8/15
from 3 to 8 are repairable = 1/5 *8/15
- exactly 5 are repairable = 5/15
exactly 5 are repairable = 1/3
These are the probabilities of the given conditions.
So, The probabilities of at least 10 are repairable is 1/3. and probabilities of from 3 to 8 are repairable is 1/5*8/15 and probabilities of exactly 5 are repairable is 1/3.

The answer is 61, x+40+5x+14=180, so x equals 21. 5(21)+14 ends up equaling 119, so 180-119 equals 1
