The correct answer is is D) If the group sells 15 prints they will loose $85.
To figure out which statement is true, we have to evaluate the function ,
for all the values given in options (A)-(D). A negative output represents a loss and a positive output will represent a profit.
In A so
. In this case we gather that if they sell 12 prints, they will make a loss of $136. This tells us that option A is wrong.
In B, so
. In this case we gather that if they sell 28 prints, they make a profit of $136. This tells us that option B is wrong.
In C, so
. In this case we gather that if they sell 35 prints, they make a profit of $225. This tells us that option C is wrong.
Lastly, so
. In this case we gather that if they sell 28 prints, they make a loss of 85 dollars. From this we gather that D is the correct option.
Answer:
a) Dice and spinner are different objects, with no relation between themselves, and thus her dice rolls and spinning outcomes are independent.
b) probability of her rolling a 4 and spinning an 8.
c) probability of her rolling an even number and spinning a number less than 3.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
A) Are her dice rolls and spinning outcomes independent or dependent?
Dice and spinner are different objects, with no relation between themselves, and thus her dice rolls and spinning outcomes are independent.
B) What is the probability of her rolling a 4 and spinning an 8?
Since the events are independent, we find each separate probability and multiply them.
Probability of rolling a 4:
One side out of 6 on the dice. So
Probability of spinning an 8:
One side out of 8 on the spinner. So
Probability of rolling a 4 and spinning an 8:
probability of her rolling a 4 and spinning an 8.
C) What is the probability of her rolling an even number and spinning a number less than 3?
Since the events are independent, we find each separate probability and multiply them.
Probability of rolling an even number:
2, 4 or 6(3 sides out of 6). So
Probability of spinning a number less than 3:
Two numbers(1 or 2) out of 8 on the spinner. So
Probability of rolling an even number and spinning a number less than 3:
probability of her rolling an even number and spinning a number less than 3.
Answer:
field goals = 36, foul shots = 28.
Step-by-step explanation:
Given:
Chamberlin scored 100 points.
Chamberlain made a total of 64 baskets consisting of field goals and foulshots.
Each field goal worth = 2 points
Each foulshot worth = 1 points
Question asked:
Find the number of field goals and the number of foul shots that chamberlain made ?
Solution:
Let number of field goals =
<u>As total of 64 baskets, he made:</u>
Then number of foul shots =
Now, total points, he scored is given 100,
<u><em>Number of field goals </em></u><u><em> 2 + Number of foul shots </em></u>
<u><em> 1 = 100</em></u>
Subtracting both sides by 64
Number of field goals = = 36
Then number of foul shots = = 64 - 36 = 28
Therefore, 36 field goals and 28 foul shots made by chamberlain.
