Answer: False
Step-by-step explanation:
There is no such deduction when a participation's questions are not answered correctly the first time. Whatever answer is given is part of the learning curve and ensures that the activity can be improved upon.
Had there been a small point deduction then there would be no opportunity to learn because there would be too much fear associated with the wrong answer.
Answer:
10
Step-by-step explanation:
The hypotenuse of a triangle is the side that is opposite to the right angle, meaning that none of its endpoints form the right angle. In this case, the hypotenuse is LN which is 10.
R = 7 in. Therefore d=14
C=pi x d
= 3.14 x 14
= 43.96
Answer:
53.57%
Step-by-step explanation:
We have to calculate first the specific number of events that interest us, if at least 3 are girls, they mean that 2 are boys, therefore we must find the combinations of 3 girls of 5 and 2 boys of 3, and multiply that, so :
# of ways to succeed = 5C3 * 3C2 = 5! / (3! * (5-3)!) * 3! / (2! * (3-2)!)
= 10 * 3 = 30
That is, there are 30 favorable cases, now we must calculate the total number of options, which would be the combination of 5 people from the group of 8.
# of random groups of 5 = 8C5 = 8! / (5! * (8-5)!) = 56
That is to say, in total there are 56 ways, the probability would be the quotient of these two numbers like this:
P (3 girls and 2 boys) = 30/56 = 0.5357
Which means that the probability is 53.57%
Answer:
L = 80.2 + 2(0.4)
(b) No, one linear equation will be sufficient to solve the problem. Because it is not two statements of equation
Step-by-step explanation:
Between 1996 and 2005, there is 10 years difference.
It is given in the question that the life expectancy increases by 0.4 every five years.
Between 1996 and 2005, life expectancy of woman born will increase by 2x0.4 = 0.8.,
In 2005, the life expectancy of woman born is:
L = 80.2 + 0.8 = 81.0 years
