Answer:
probably an update which sucks tell me about it lol
Answer:
Presumably you're solving for x here? Without further information we'll assume that.
With that in mind, x is approximately equal to 0.86 and -0.46
Step-by-step explanation:
Let's start by putting it in the usual ax² + bx + c format.

let's solve it. First we'll multiply both sides by five, making the first term a perfect square:

Now we'll add 11 to both sides:

Which makes the left side a perfect square:

And now we can solve for x:

Note that there's no apparent way of drawing the ± symbol when editing equations, so take that + sign as actually being ±.
That gives us two answers:

Answer: Yes, we have.
Step-by-step explanation:
Going by the details provided, Probability of success of choosing a citizen with a fitness band 27%
The probability function for expected value shows the Formula to know with sufficient dependence what proportion of the sampled people will have the fitness band.
Since 27% of 500 = 135.
and 135 is more than a quarter of 500(125), then we have enough Evidence that more than a quarter of this age group own a fitness band.
Answer:
1/18
Step-by-step explanation:
P(Orange AND Red)
= P(Orange socks)*P(Red shirt)
= 1/3*1/6
= 1/18
Answer:
AB = 12.5
Step-by-step explanation:
BX is an altitude and a median. That means that triangle ABC is isosceles.
AB = CB
<u>AB = 12.5</u>
