Circumference at latitude L = (2 pi Earth's radius) cos(L).
Using conditional probability, it is found that there is a 0.7873 = 78.73% probability that Mona was justifiably dropped.
Conditional Probability
In which
- P(B|A) is the probability of event B happening, given that A happened.
- is the probability of both A and B happening.
- P(A) is the probability of A happening.
In this problem:
- Event A: Fail the test.
- Event B: Unfit.
The probability of <u>failing the test</u> is composed by:
- 46% of 37%(are fit).
- 100% of 63%(not fit).
Hence:
The probability of both failing the test and being unfit is:
Hence, the conditional probability is:
0.7873 = 78.73% probability that Mona was justifiably dropped.

<h3>The exact probability that the blue ball is drawn first and the red ball is drawn second is
</h3>
<em><u>Solution:</u></em>
<em><u>The probability of an event is given as:</u></em>
Given that,
There are 12 balls in a bag
One is blue and one is red
Favorable outcome = blue ball is drawn first
Favorable outcome = 1
Therefore,
Now, without replacement, red ball is drawn second
Therefore,
Total possible outcomes = 12 - 1 = 11
<em><u>What is the exact probability that the blue ball is drawn first and the red ball is drawn second?</u></em>
Thus the exact probability that the blue ball is drawn first and the red ball is drawn second is
So what we are going to do is subtract 350 minus 36percent. That is 224. So there are 224 students in this year's 6th grade class!
Hope this helps!

Answer:
B) (4x-5i)(4x+5i)
Step-by-step explanation:
The expression can be treated as the difference of squares, and factored accordingly. That factoring is ...
a² -b² = (a -b)(a +b)
__
Here, we have ...
a² -b² = 16x² -(-25)
a² = 16x² ⇒ a = 4x
b² = -25 ⇒ b = √-25 = 5i
Then the factoring is ...
(a -b)(a +b) = (4x -5i)(4x +5i)
