Answer:
He needs to get 1 right
Step-by-step explanation:
1/40 is equal to .025. This means the other 39/40 incorrect ones are worth .975(97.5%). If we multiply the .975 by the 15 percent of his overall grade, we get 14.625. When you subtract this from the overall grade, you get 70.075, which is just above a 70%.
Answer:
The correct option is B.
Step-by-step explanation:
The given function is
The new function is
.... (1)
It is in the form of
.... (2)
Where, m is a constant.
If m is negative, then there is a vertical reflection over x-axis. If the constant is greater than 1, we get a vertical stretch and if the constant is between 0 and 1, we get a vertical compression.
From (1) and (2), we get
Since the value of m is negative and absolute value of m is between 0 and 1, therefore the graph g(x) shows the vertical reflection over x-axis and vertical compression.
Option B is correct.
Answer:
I did not get this one right, but I will tell you that I know a lot of people, including me who put:
B and D.
Those two together are NOT right. and the other question I got wrong was number 5. That answer is not D. So don't put that. Everything else, I got correct.
Step-by-step explanation:
Answer:
a.) Digits on the 5 cards are 1,2,3,4,5. You pick one card. You win if you pick a card having an even number.
b) Digits on the 5 cards are 1,2,3,4,5. You pick two cards. You win if you pick fist the card having number 5 and then the card having number 4.
Step-by-step explanation:
a) The probability of picking an even number is:
picking a card with even numbers (picking 2 or 4) / all cards (1,2,3,4,5)
b) Probability of picking the card having 5 first
Then the probability of picking the card having number 4 from the remaining 4 cards:
<em>Combined probability</em>, that is picking first number 5 and then number 4 is
