The best answer out of the ones provided would be c, confidence interval
So, its time to do some MATH!
ok so i would first approach this problem by placing the prices in order from least to greatest......um it would look something like this...(cue the math skills in my brain)
1.29,1.59,1.99,2..09, and last but most definitely not least (get it?) 2.19
so basically the median is like the MIDDLE number of your data (shout out to my fellow middle children!)
and so you may be asking "how does one figure this out?" and i will tell you that it is quite simple...
so what you got to do is cross out a number from the left and a number from the right, and you will be left with one number, which is your middle number (or in fancy maths language -the median- that was supposed to be said with a British accent, so just bear with me there :-))
and so your final answer should be....(drumroll please)
$1.99 is your median
(ta- da you are supermathematicalgeniuslevel smart)

Answer:
x=29
Step-by-step explanation:
the line in the middle of the triangle is at a right angle, so each side of it must equal 90 degrees, so then 90=3x+3, 90-3=3x then you simply, 87=3x which equals x=29.
Answer:
So we have
.
Step-by-step explanation:
Ok so we are in quadrant 2, that means sine is positive while cosine is negative.
We are given
.
So to find the opposite we will just use the Pythagorean Theorem.




This is the opposite side.
Now to find
and
.
.
Some teachers do not like the radical on bottom so we will rationalize the denominator by multiplying the numerator and denominator by sqrt(5).
So
.
And now
.
So we have
.
Answer:
2.25
Step-by-step explanation:
-3x+10=5x-8
+8 +8
-3x+18=5x
+3x +3x
18=8x
_ _
8 8
2.25=x
