Answer:
A
Step-by-step explanation:
Look at each part of the intersection first:
K U M is everything in K and everything in M.
K U L is everything in K and everything in L.
The intersection of these two union sets will be what they share in common.
They both have the entire set of K and they both have what L and M have in common since each set had L or M. This means A is the best choice.
Hope this help to answer you question.
Sure. The formula for an infinite geometric series with first term <em>a</em> and common ratio <em>r</em> says it converges when |<em>r</em>|<1; in that case the sum is
Q3. r=-4/5 (converges), a=5, S=5/(1- -4/5) = 5/(9/5) = 25/9
Answer: a
Q4. r=1/6 (converges), a=420, S=420/(1-1/6) = 420/(5/6) = 6(84) = 504
Answer: a
Q5. r=1.2, diverges
SUPER EASY QUESTION FOR POINTS what is the median of the data? 12, 17, 16, 10, 20, 13, 14, 14, 12, 12, 19, 18
Alisiya [41]
Median means lets say you have a set of numbers arranged in increasing numerical value
the one in the middle is the median
example
1,2,3
2 is the median since it is in the middle
1,2,3,4,5
3 is median becasue it is in middle
in our case
just count form both ends or something to get to middle
we get to 13 or 14
since 14 is the given answer choice, the answer is 14
y in (-oo:+oo)
(3/8)*y+1/2 = (5/8)*y+5/12 // - (5/8)*y+5/12
(3/8)*y-((5/8)*y)+1/2-(5/12) = 0
(3/8)*y+(-5/8)*y+1/2-5/12 = 0
1/12-1/4*y = 0 // - 1/12
-1/4*y = -1/12 // : -1/4
y = -1/12/(-1/4)
y = 1/3
y = 1/3
