a. 76
b. 72
c. 73
d. 67

Answers

Answer 1
Answer: To find the mean (average) score of the top ten finishers in the golf tournament, you need to sum up all the scores and then divide by the number of scores (which is 10 in this case).

Sum of the scores: 71 + 67 + 67 + 72 + 76 + 72 + 73 + 68 + 72 + 72 = 720

Now, divide the sum by the number of scores:

Mean score = 720 / 10 = 72

So, the mean score is 72, which corresponds to option (b).
Answer 2
Answer:

Final answer:

The mean score is 72.

Explanation:

To find the meanscore, you need to add up all the scores and then divide the sum by the number of scores. In this case, we have 10 scores, so the mean score is the sum of these scores divided by 10.



Adding up the scores, we have: 71 + 67 + 67 + 72 + 76 + 72 + 73 + 68 + 72 + 72 = 720



Dividing the sum by 10, we get the mean score: 720 / 10 = 72

Answers

Answer:

Option 4 is correct that is according to fundamental theroem of algebra the given polynomial function will have 5 roots

Step-by-step explanation:

The fundamental theorem of algebra says that the polynomial will have  the number of roots  equal to the degree of the polynomial.

Degree is the highest power of polynomial.

Here we have given the polynomial 4x^5-3x where degree is 5.

Hence, the given polynomial will have 5 roots.

Therefore, option 4 is correct that is 5 roots

Look at the first Model It on the previous page. Why do you double 8 to find theamount of money Julie will have on Day 4?.

Answers

Answer:

Doubling a number means multiplying it by 2. If there is a pattern or rule that suggests doubling is necessary, it could be based on a specific mathematical relationship or calculation.

Step-by-step explanation:

For example, if there is a consistent pattern of doubling in a mathematical sequence, it could indicate exponential growth or a specific mathematical operation being applied. In some scenarios, doubling may be necessary to account for the accumulation or growth of a value over time.

It is important to note that without the specific context or information provided on the previous page, it is difficult to give a definitive explanation for why 8 is being doubled to find Julie's money on Day 4.

B. Their slopes are opposites.
C. Their slopes are equal.
D. Their slopes are negative reciprocals.

Answers

I believe the correct answer from the choices listed above is option C. If two lines are parallel, their slopes are equal. Having equal slopes mean that the rise and run of the points of the lines are the same. Parallel lines do not intersect even when extended infinitely.

Answer:

C. Their slopes are equal.

Step-by-step explanation:

Given : If two lines are parallel.

To find  : which statement must be true.

Solution : We have given that If two lines are parallel.

We know that two parallel line have same slope

By rise over run :

Therefore, C. Their slopes are equal.
