Let <em>X</em> be a random number selected from the interval. Then the probability density for the random variable <em>X</em> is
8 and 10 are the only even integers that fit the given criterion (6 is more than 0.25 away from 6.35), so that we're looking to compute
P(|<em>X</em> - 8| < 0.25) + P(|<em>X</em> - 10| < 0.25)
… = P(7.75 < <em>X</em> < 8.25) + P(9.75 < <em>X</em> < 10.25)
… = P(7.75 < <em>X</em> < 8.25) + P(9.75 < <em>X</em> < 10)
(since P(<em>X</em> > 10) = 0)
… = 0.2740 (8.25 - 7.75) + 0.2740 (10 - 9.75)
… = 0.2055
Answer:
B) 
Step-by-step explanation:
To find the expression equivalent to 
, we must simplify the given expression. This can be done by applying an exponent rule:
In the context of our problem, we would have:
Therefore, when that exponent is distributed, we get:
Simplified, we have:
Answer:
4<u
Step-by-step explanation:
14>u+10
14-10>u
4>u
Also, I've heard of something of "flipping" your sign when you minus a number or something. Can anyone explain that to me??
Answer:
you substitute x for 4 and so you multiply 9 x 4 which will give you 36 and then you have to add four times y so you substitute y for -3 and you add 36 - 12 which will give you 24
