Answer:
The fisrt one were it almost hits 3
Step-by-step explanation:
<u><em>Answer:</em></u>
Part a .............> x = 11
Part b .............> k = 57.2
Part c .............> y = 9.2
<u><em>Explanation:</em></u>
The three problems deal with inverse variation between two variables
An inverse variation relation between two variables means that when one of the variables increases, the other will decrease (and vice versa)
<u>Mathematically, an inverse variation relation is represented as follows:</u>

where x and y are the two variables and k is the constant of variation
<u><em>Now, let's check the givens:</em></u>
<u>Part a:</u>
We are given that y = 3 and k = 33
<u>Substitute in the original relation and solve for x as follows:</u>

<u>Part b:</u>
We are given that y = 11 and x = 5.2
<u>Substitute in the original relation and solve for k as follows:</u>

<u>Part c:</u>
We are given that x=7.8 and k=72
<u>Substitute in the original relation and solve for y as follows:</u>
to the nearest tenth
Hope this helps :)
Answer:
3 :4
Step-by-step explanation:
Remember that odds are different than probability
favor : not in favor ( drawing something other than white)
9 white : 12 not white
Divide each by 3
9/3 : 12/3
3 :4
Step-by-step explanation:
a) The 3rd row has 37 seats, the 4th row has 45 seats and the 5th row has 53 seats.
b) This is an arithmetic sequence because the values differ by a constant quantity.
c) You need to find the nth term of the sequence:
21 = 1×8+x
x=13
So the nth term is 8x +13.
The 100th term would be 813.
