At a baseball game, one lucky ticket holder will win an all-expense paid family vacation from one of the baseball team's corpora

te sponsors. There are 5,000 ticket holders at the game. The sponsor wants to place chips, labeled with the seat numbers of each ticket holder, in a bin and draw the winner from the bin. Unfortunately, the bin will only hold 500 chips. Which of the following best describes a method of assuring that the corporate sponsor can use the bin for the drawing and that each ticket hold has a fair change of winning?
A.
Randomly assign the 5,000 ticket holders to 50 equal-size lots. Then, randomly select five of the lots and place them in the bin. Randomly select the winner of the all-expense paid family vacation from the bin.

B.
Place chips, labeled with the seat numbers of each ticket holder, into ten lots based on age. Then, randomly select one of the lots and place it in the bin. Randomly select the winner of the all-expense paid family vacation from the bin.

C.
Given that the corporate sponsor's bin can only hold 500 entries, there is no way to assure that each of the 5,000 ticket holders has a fair chance of winning the all-expense paid family vacation.

D.
Place the chip, labeled with the seat number of the first 500 ticket holders, into the bin, and randomly select the winner of the all-expense paid vacation from the bin.

Write an equation of the line that is perpendicular to y = 1/2x + 3 and passes through the point (10, -5).
o-na [289]

Answer:

Option A) y = -2x + 15

Step-by-step explanation:

step 1

Find the slope of the line perpendicular to the given line

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

The equation of the given line is

y=\frac{1}{2}x+3

so

The slope of the given line is  m=\frac{1}{2}

therefore

The slope of the line perpendicular to the given line is

m=-2

step 2

Find the equation of the perpendicular line in point slope form

y-y1=m(x-x1)

we have

m=-2

point\ (10,-5)

substitute

y+5=-2(x-10) ---> equation in point slope form

Convert to slope intercept form

y=mx+b

y+5=-2x+20

y=-2x+20-5

y=-2x+15

Rewrite the sum product of the gcf 9+15 and a new sum
ycow [4]
GCF(9; 15) = 3

9 = 3 · 3
15 = 3 · 5

9 + 15 = 3 · 3 + 3 · 5 = 3·(3 + 5)

Used distributive property: a(b + c) = ab + ac
