Answer:

The correct option is A) No x-intercepts.

Step-by-step explanation:

Consider the provided information.

Nature of solution based on the value of discriminant :

If D = b² − 4ac > 0 then there exist two Real Solutions or roots.

If D = b² − 4ac = 0 then there exist one Real Solutions or roots.

If D = b² − 4ac < 0 then there exist no Real Solutions or roots

Here, we need to remember that the root of an equation and x-intercepts are the same thing.

Now consider the provided information.

The graph of an equation with a negative discriminant means:

D = b² − 4ac < 0

From the above values of discriminant we can say, there exist no Real roots or no x-intercepts.

Thus, the correct option is A) No x-intercepts.

On a typical day, a jewelry store sells 8 bracelets. The data show the number of bracelets sold on each day for four weeks at a
mote1985 [20]

For which week would the mean of the data be a good estimate of the jewelry store's weekly sales throughout the year?

Answer: Week 4's mean would be a good estimate of the jewelry store's weekly sales throughout the year. Because the average of the Week 4's sales is 8. Also we can see the Week 4's data appears without outliers. So the option Week 4: 9, 7, 8, 8, 11, 6, 7  would be a good estimate of the jewelry store's weekly sales throughout the year.

<u>Explanation:</u>

Week 1's mean is:

\frac{7+8+7+9+1+6+8}{7} =\frac{46}{7} =6.57

Week 2's mean is:

\frac{6+7+8+7+9+8+17}{7} =\frac{62}{7} =8.86

Week 3's mean is:

\frac{3+1+2+3+2+3+2}{7} =\frac{16}{7} =2.29

Week 4's mean is:

 \frac{9+7+8+8+11+6+7}{7} =\frac{56}{7} =8

Since the week 4's mean is 8, which is same as typical day's sale of bracelet's. Therefore, week 4 will be good estimate of the jewelry store's weekly sales throughout the year.
