Answer:
x² - 20x - 12 = 0Step-by-step explanation:
One root is given, 10 - 4√7.
Since the polynomial has to have rational roots and of a minimal degree, the other root is the conjugate of the given and the polynomial is of degree 2 minimum.
The polynomial is:
(x - 10 - 4√7)(x - 10 + 4√7) = 0x² - (10 - 4√7 + 10 + 4√7)x + (10² - (4√7)²) = 0x² - 20x + 100 - 112 = 0x² - 20x - 12 = 0Related Questions

The numbers which are decimals by nature can be represented in the form of fractions. For example, 0.5 can also be written as 5/10. ... Percentages refer to decimal numbers to the base 100. These are represented by a % (percent sign).Since a percent is a ratio a ratio can be written as a fraction. This means any of these forms can be converted to any of the others.

40% of the 7920 visitors to an amusement park were children. 25% of these children and 1/3 of the adults were repeat visitors. How many percent of the visitors were visiting the amusement park for the first time?
Total number of visitors = 7920
Find the number of children:
Children = 40% of 7920
Children = 0.4 x 7920
Children = 3168
Find the number of adults:
Adult = 7920 - 3168 = 4752
Find the number of repeated visitors that are children:
Repeated visitors = 25% x 3168
Repeated visitors = 0.25 x 3168
Repeated visitors = 792
Find the number of children that are visiting for the first time:
First time visitors = 3168 - 792 = 2376
Find the number of repeated visitors that are adult:
Repeated visitors = 1/3 x 4752
Repeated visitors = 1584
Find the number of adults that are visiting for the first time:
First time visitors = 4752 - 1584 = 3168
Find the total number of first time visitors:
Total number of first time visitors = 3168 + 2376 = 5544
Answer: There are 5544 visitors that are visiting for the first time

Answers
Answer:
the answer is more than 241 because 0-60 minutes time 8 would be 480 but 241 time 2 is 482
The model class for the distribution is 0-60. Therefore, option A is the correct answer.
Given that, a survey of statistics students asked how much time they spent on a computer during a 24-hour period.
We need to identify the model class for the distribution.
What is the model class?The modal class is the class with the highest frequency. We know that the mode is the number or observation that most often appears. So, the modal class is the class in grouped data that contains the mode. That means the class that has the highest frequency is the modal class of the grouped data.
Now, from the given data table we can see the highest frequency is corresponding to the class 0-60.
The model class for the distribution is 0-60. Therefore, option A is the correct answer.
