A jar contains 100 tickets for a drawing. Among those tickets are 7 winning tickets. What are the odds in favor of winning?

Answers

Answer 1

Answer:

7:43

Step by Step:

50 - 7 = 43

You take out those seven tickets from the fifty, because if not, there would be 57 tickets total. This leaves 7:43. The seven is first because the odds are in the "winning tickets" favor.

Answer 2

Answer: 7/100 or 0.07% chance

Answer:

1. B

2. B

Step-by-step explanation:

** Attached picture of the situation

The bird caught the fish at point A, flew until B (which is 100 yds away, dropped the fish at C (which is horizontally 50 yards from A).

We want the angle that the bird creates with the water (horizontal). It is angle BAC. With respect to the right triangle, we can say that we know "hypotenuse" and "adjacent" side to angle BAC. cosine relates hypotenuse and adjacent, thus we can write:

$Cos(BAC)=(50)/(100)\nCos(BAC)=(1)/(2)\nBAC=Cos^(-1)((1)/(2))\nBAC=60$

correct answer is B

Here, we want to find the distance (length) of segment BC. With respect to the angle BAC (we found to be 60), we can say BC is "opposite". We know hypotenuse to be 100. So let's use sine, since sine is ratio of opposite to hypotenuse. Thus, we can write:

$Sin(BAC)=(BC)/(100)\nSin(60)=(BC)/(100)\nBC=Sin(60)*100\nBC=86.6$

correct answer is B

The answers should be B)60 and B) 86.6

Step-by-step explanation:

Ian picked 5 times as many berries as Michelle. Joe take seven times as many theories as Michelle. Together they picked 208 berries. how many berries did Joe pick? draw a diagram and explain how you found your answer

Answers

$x-\ number \ of\ Michelle's\ berries\ny-\ number\ of \ Joe's\ berries\nz-number\ of \ Ian's\ berries\n\nz=5x\ny=7x\nx+y+z=208\n\nx+5x+7x=208\n\n13x=208\ \ \ \ | divide\ by\ 13\n\nx=16\n\ny=16*7=112\n\nJoe\ picked\ 12\ berries.$

Ian =x
Michelle=y
Joe=z

5y=x
7y=z
so 5z=35y=7x
5z=7x
208=x+y+z
substitute
x and z to get
208=(5y)+y+(7y) or
208=13 y
divide both sides by 13
michelle picked 16
Joe picked 7 times than Michelle so
16 times 7=112

Hello everyone! I really need these two by Friday. & can you explain how you got the answer to the top one? Thank you all in advance!!!!!!!!! (it's just two)

Answers

the answer to the first:

x>9 ⇒ x∈(9,+∞)
the graph shows that the x is bigger that 9 but IT CAN'T BE 9, we can tell that because the inner of the dot is white (if the inner of the dot was black too it would meant that the x would be bigger that 9 but it could be 9 as well).
I also inserted a picture which shows what I'm talking you about (just ignore the greek on the top).

the answer to the second:

4(3x)+7-5x-5+3y-y=
= 12x+7-5x-5+3y-y
=7x-2y+2
