A1,a2,a3....a30-each of these 30 sets has 5 elements.b1,b2,....bn-each of these n sets has 3 elements.union of a1,a2...a30=union
zzz [600]
 the number of elements in the union of the A sets is:5(30)−rAwhere r is the number of repeats.Likewise the number of elements in the B sets is:3n−rB
Each element in the union (in S) is repeated 10 times in A, which means if x was the real number of elements in A (not counting repeats) then 9 out of those 10 should be thrown away, or 9x.  Likewise on the B side, 8x of those elements should be thrown away. so now we have:150−9x=3n−8x⟺150−x=3n⟺50−x3=n
Now, to figure out what x is, we need to use the fact that the union of a group of sets contains every member of each set.  if every element in S is repeated 10 times, that means every element in the union of the A's is repeated 10 times.  This means that:150 /10=15is the number of elements in the the A's without repeats counted (same for the Bs as well).So now we have:50−15 /3=n⟺n=45

Help please (question is kinda easy and its timed so i need help asap)

Option 1: y = 5x+5 is the correct answer

Step-by-step explanation:

We can put the values of x in each option one by one and then compare the output to find the best option

So,

<u>For y = 5x+5:</u>

Putting x=1,2,3,4,5...

y = 5(0)+5 = 0+5 = 5\\y = 5(1) +5 = 5+5 = 10\\y = 5(2) + 5 = 10+5 = 15\\y = 5(3) + 5 = 15+5 = 20

The values of x in the function are producing the output values of y, which means that the function for values given in the table is defined by: y= 5x+5

Hence,

Option 1: y = 5x+5 is the correct answer

Explain pls and thanks
murzikaleks [220]

Starting more simply, if we wanted to know how many students like pink in general, that's 68/100. We could do that for each single category and the fractions would add together to equal 1. Now say we wanted to know something about that 68/100 people. That 68 is our new 100%, or another way of looking at it is if we take however many people like pink and don't like black and those that do like black, they will equal 68/68.

The number of people that like pink but don't like black is 41/68 and those that like pink and black are 27/68. 27+41=68 For the question of your problem it is asking about those that do not like pink which you can tell from the table or use from my saying 68/100 like pink is 32. Now you can split that into those that do or don't like black, and the two results will equal 32/32.
