Claudia has test scores of 78, 88, 84, 92, 76, 98. If she wants to end up with a ''B'' average, what does she need to score on her next test?
Joe made 15 points in a basketball game, 3 points are given for a long shot, 2 points given for a field goal, and 1 point is given for a free throw. In how many ways can Joe score 15 points?
If the lowest grade for a B average is 80, then she needs a total of 7 * 80.
Add the scores she has and subtract the sum from the product above to find the lowest score she needs for the next text.
7*80 = 560
the scores make a total of 516
560 - 516 = 44 <-- Is this correct?
Steve said it's not correct I don't see how it's not if I did exactly what you said. & I checked the multiplication several times, so?
Can you please just help me and reply with the 2nd problem, Joe made 15 points...
Yes, she needs 44.
Why won't you show me what to do for the second one!
To find out what Claudia needs to score on her next test, we need to calculate her current average score and compare it to the requirements for a "B" average.
Step 1: Calculate the total sum of Claudia's current test scores:
78 + 88 + 84 + 92 + 76 + 98 = 516
Step 2: Calculate the average of Claudia's current test scores:
516 / 6 = 86
Step 3: Determine the minimum average required for a "B" grade. This can vary depending on the grading system, but for example, let's assume a "B" grade requires an average of at least 80.
Step 4: Calculate the minimum total score needed to achieve a "B" average:
80 * (6 + 1) = 560
Step 5: Calculate the score Claudia needs on her next test:
Score needed = Minimum total score - Current total score
Score needed = 560 - 516
Score needed = 44
Therefore, Claudia needs to score at least 44 on her next test to achieve a "B" average.
Now, let's move on to the second question:
Joe wants to score 15 points in a basketball game. There are three ways he can accomplish this based on the given scoring system:
1. Long Shots: Joe can make 5 long shots (15 / 3 = 5). In this case, he scores 5 * 3 = 15 points.
2. Field Goals: Joe can make 7 field goals and 1 free throw (15 / 2 = 7 remainder 1). In this case, he scores 7 * 2 + 1 * 1 = 15 points.
3. Free Throws: Joe can make 15 free throws (15 / 1 = 15). In this case, he scores 15 * 1 = 15 points.
Therefore, Joe can score 15 points in three different ways.
