Answer:
Probability that, of the questions studied, all three were the test questions selected by the professor is 0.05
Step-by-step explanation:
Total question gives by teacher = 6
A student has time to study for only three of these six questions.
We are supposed to find the probability that, of the questions studied, all three were the test questions selected by the professor?
So, Probability that, of the questions studied, all three were the test questions selected by the professor =
=
=
Hence Probability that, of the questions studied, all three were the test questions selected by the professor is 0.05
X2+4x−5<span>5<span>x2</span>−8x+3</span>×<span><span>20x−12</span><span><span>x2</span>−6x−55</span></span>
start by doing some factoring
<span><span><span>(x+5)(x−1)</span><span>(x−1)(5x−3)</span></span>×<span><span>4(5x−3)</span><span>(x−11)(x+5)</span></span></span>
cancel common factors and then see whats left...
So you cancel (x+5) and 4(5x-3)?
Answer:
x=94
Step-by-step explanation:
I hope I'm correct. Here's my explanation: x+9 and 2x-111 would equal 180, hence the line (supplementary). So x+9+2x-111=180
x=94
hope this helps.
