Area=pi (radius^2) Plug in numbers.
206=3.14 (r^2) Divide both sides by 3.14
65.61=r^2 Then square root both sides.
8.1ft =r Then round to the nearest foot.
r=8ft
There are several information's of immense importance already given in the question. Based on those information's. the answer can be easily deduced.
We already know that
y = mx + b
Then
Slope for GH = (6 - 2)/(- 2 - 2)
= - 1
We already know that parallel lines have the same slope
Then
<span>6 = -1(5) +b
</span>6 = - 5 + b
b = 11
Then, the equation is
y = x + 11
From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the last option or the fourth option.
Using it's concept, the probabilities are given as follows:
19. A. 1/3.
20. F. 1/6.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there are 1 + 1 + 3 + 4 + 3 = 12 papers. 4 have a score of 6, hence, in item 19, the probability is:
p = 4/12 = 1/3.
Which means that option A is correct.
2 papers have a score greater than 12, hence the probability in item 20 is given by:
p = 2/12 = 1/6.
Which means that option F is correct.
