Answer:
Jeff got 20 answers right.
Step-by-step explanation:
The maximum number of points Jeff can get is 100. (25 * 4) However, for each question he gets wrong, he's actually losing 6 points because he doesn't get the four points for getting right, and has the additional -2 points for getting it wrong. Since he only got a score of 70, that means he lost 30 points.
30/6 = 5. So he missed 5 question and got 20 question right.
Answer:
The combination is 15
Step-by-step explanation:
There are 6 people in a raffle drawing. two raffle winners each wing gift cards . each gift card is the same.
Lets call the winners Winner 1, Winner 2. According to the given statement each gift card is same, thus any permutation of these two winners are equivalent.This tells us that the order of winners does not matter and the situation involves a combination.
Now we have to calculate the combination of 2 winners from 6 people.
nCm = m!/n!(m-n)!
where m = 6
n = 2
2C6 = 6!/2!(6-2)!
2C6 = 6!/2!(4)!
2C6 = 6*5*4*3*2*1/2*1*4*3*2*1
2C6= 6*5/2*1
2C6=30/2
2C6 = 15
Thus the combination is 15....
The scale used to make the model was 125 meters = 1 foot. 525 divided by 4.2 equals 125 meters.
The mode is 84 sheets of plywood tall.
4.2 feet = 50.4 meters
50.4 meters divided by 0.6 equals 84 sheets.
