A carnival has a duck pond booth. You choose a rubber duck at random. The mark on the bottom of the duck tells you whether you won a small, medium, or large prize, or no prize at all. There are 65 ducks floating in the pond. There are 3 marked as large-prize winners, 13 ducks marked as medium-prize winners, and 21 ducks marked as small-prize winners. Find the theoretical probability of winning a medium prize at the duck pond. Express your answer as a decimal. If necessary, round your answer to the nearest thousandth.0.2

Answers

The theoretical probability of winning a medium prize at the duck pond is 0.2, Hence option A is correct.

What is probability?

Probability is the ratio of number of favorable outcomes and total number of outcomes. it deals with finding out the likelihood of the occurrence of an event.

According to the given information,

Number of medium-prize winning ducks = 13

The total number of ducks = 65

The theoretical probability of winning a medium prize at the duck pond can be found by dividing the number of medium-prize winning ducks (13) by the total number of ducks (65).

So, the probability of winning a medium prize is,

= 13/65

= 0.2 or 20%

Therefore, the theoretical probability of winning a medium prize at the duck pond is 0.2 or 20%.

Hi there! :)  I believe the answer is 0.2. The way I got 0.2 is because there are 13 medium-sized ducks and there are 65 total ducks floating I did 13/65( 13 divided by 65) which equals 0.2. For theoretical probability you divide by the number of outcomes.

The variable is what we are finding
−​5/19​​x>−3

Answers

it could be 2 things
(-5/19)x>-3 or
-5/(19x)>-3
if it is the first one, go to AAAAAA
if it is second one go to BBBBBBB


(-5/19)x>-3
multiply both sides by -19/5 to clera fraction (-5/19 times -19/5=-95/-95=1)
x>-57/5
x>-11 and 2/5


BBBBBBBBB
-5/(-19x)>-3
multiplyboth sides by -19x
-5>57x
divide both sides by 57
-5/57>x


if it is (-5)/(19)x>-3 then  x>-57/5
if it is (-5)/(19x)>-3 then x<-5/57

Substitution: y-2x=-6 and 5x-y=9

Answers

y-2x=-6 and 5x-y=9   

step 1: isolate y in the first equation

y = 2x - 6

step 2:  substitute the y value on the 2th equation:

5x-(2x-6)=9

step 3:  solve the present equation:

5x - 2x + 6 = 9
3x = 9-6
3x = 3
x = 1

step 4: get the y value by replacing the value of x in y = 2x - 6:

y = 2*1 - 6
y = 2 - 6
y = -4

S={1, -4}

B. 19.6 square feet

C. 42.8 square feet

D. 78.6 square feet

Answers

Area of a circle is πr^2.

From this, we can calculate
π*2.5^2
= π*6.25
= 19.625
= 19.6
