Answer:
The value of x fro the given equation is ( 4 + 2 i ) , ( 4 - 2 i )
I.e option D
Step-by-step explanation:
Given equation as :
x² - 8 x + 41 = 0
For quadratic equation ax² + b x + c = 0
The value of x = 
∴ For equation x² - 8 x + 41 = 0
Or, x = 
Or, x = 
Or, x = 
∴ x = ( 4 + 2 i ) , ( 4 - 2 i )
Hence The value of x fro the given equation is ( 4 + 2 i ) , ( 4 - 2 i )
I.e option D Answer
7+6. is one of them hope this helps
Answer:
c) 18 + 45m
Step-by-step explanation:
9(2+5m)
We multiply the 9 by each term inside the parentheses
9*2 + 9*5m
18+45m
OK.
USUALLY when they give you this kind of graph (histogram),
each bar tells you the NUMBER of individuals that fall into
that particular range.
This graph is a little bit different ... it's easier.
On this graph, they're showing you the PROBABILITY that
an individual is in that particular range.
(The y-axis is labeled 'P', and they told us it's a "probability distribution".)
The graph is telling us that if you close your eyes and pick one giraffe,
he has a 25% chance of being 4 years old or younger, a 10% chance of
being between 4 and 8, a 35% chance of being between 8 and 12, and
a 5% chance of being between 16 and 20.
This is just a fancy, slightly confusing way of saying that 25% of the
giraffes in that zoo are 4 or younger, 10% of them are between 4 and
8, 35% of them are between 8 and 12, and 5% of them are between
16 and 20.
Before we worry about answering the question, we can spot a few
interesting things about the giraffe population at that zoo:
-- There are NONE that are between 12 and 16 years old. Weird.
-- The percentages only add up to 75%. So 25% of the giraffes
must be older than 20 ! They're just not included on the graph.
OK. So the question asks: What's the probability that a giraffe
you pick is between 8 and 20 ?
-- He's got a 35% chance of being between 8 and 12, no chance
at all of being between 12 and 16, and a 5% chance of being
between 16 and 20.
Can you see that his chance of being between 8 and 20 is
(35% + 0% + 5%) = 40% ?
