Justin is 2 years older than one third marcellas age. aimee is four years younger then 2 times Justins age.Define a variable and wrute an expression to represent justins age. The. Justins age and Aimees age if Marcella is 63 years old

Answers

j=justin
marcella=m
aimee=a

j is 2 older than 1/3 of m
'of' means multiply
j=2+1/3m

a is 4 younger than 2 times j
a=-4+2j

represent justin's age?
dunno



ok so I can solve if I know m=63
j=2+1/3m
j=2+1/3(63)
j=2+21
j=23
subsitute
a=-4+2j
a=-4+2(23)
a=-4+46
a=42

justin is 23 and aimee is 42 if marcella is 63

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
0.8

0.569

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 triangle on the left area is 18 because the area of a triangle is 1/2 b times h so 12 times 3 times 1/2 equals 18.you then cut a triangle from the quadrilateral to make into a triangle.The triangle is the same height has other triangle so its area is 18.Since you took three for base of left and right triangle you subtract 6 from 1 to make it your base of 8 and your height is 12 and 12 tikmes  8 is 96 so 18+18+96=132 so our answer is 132.
