Answer:
C) (x + 3i)(x - 3i)
Step-by-step explanation:
(x + 3i)(x - 3i)
=x² - (3i)² [(a+b)(a-b)=a²-b²]
=x² - 9i²
=x² - 9(-1) [i²=-1]
= x² + 9
It would be $4.60 because $2.30x2=4.60
Answer:
I'm pretty sure any that is not RT if im I understand what this is asking.
Step-by-step explanation:
a diameter would go through the middle, and the only one thats does go through the entire circle is RT
Let
x---------> <span>The probability that a student takes Spanish
y-------> </span><span>the probability that a student takes Drivers Education given that the Student is taking Spanish
z-------> </span><span>The probability that a student at school takes Drivers Education and Spanish
we know that
z=x*y------> solve for y
y=z/x
z=87/1000
x=68/100
substitute
y=(87/1000)/(68/100)-----------> y=87/680
the answer is
87/680</span>
