Answer:
the derivative of sinx is cosx, so an antiderivative of cosx is sinx.
Answer:
a) 0.504
b) 0.2
Step-by-step explanation:
Let's call the events A, B, and C where
A = She passed the first exam
B = She passed the second exam
C = She passed the third exam
Then
A∩B = She passed both the 1st and 2nd exam
A∩ B∩ C = She passed all the 3 exams
a)
We want to determine P(A∩ B∩ C)
We have
P(A) = 0.9
P(B|A) = 0.8
and
So,
P(A∩ B)=0.72
Now we know
P(C| A∩ B)=0.7
Then
and
P(A∩ B∩ C) = 0.504
b)
Since the probability that she passes the second test given that she passed the 1st one is 0.8, then the probability that she does not pass the second test given that she passed the 1st would be 1- 0.8 = 0.2
Answer:
d
Step-by-step explanation:
10% would be 985.00 but 13.1% should be 1290.35
Answer:
When you have a equation such as
y = 2x + 4
This means, that whatever x equals, do the rest equation for y. They give you a table, the numbers under x, you replace x with the x in the equation. Multiply it next to the number. Do the rest of the equation, that is how you get y.
Once you do all x numbers, you have to graph it.
X = run
Y = rise
X is the horizontal line
Y is the vertical line

Look at the middle, the x numbers that are to the right of the vertical line are negative.
The ones to the left are positive.
The numbers that are on the top of y are positive
The numbers that are on the bottom are negative.

21 is 25% of 84
21 • 4 = 84
You can check this answer by take 25% of 84.
84 • 0.25 = 21
