I think the correct answer is false. A figure is not only a quadrilateral if and only if it is a polygon. A polygon can have three or more sides. A<span> </span>polygon <span>is a plane figure that is bounded by a finite chain of straight line segments closing in a loop to form a closed chain or circuit</span>

Find the experimental probability that exactly 3 of 4
otez555 [7]

Answer:

4 / 20 (1 / 5)

20%

Step-by-step explanation:

The experimental probability is what actually happens in an experiment (as opposed to an authentic probability calculated from genetics).

In this experiment, there are 3 outcomes with :

3 tails and 1 head

(tails represent female, head represent male)

So, 4 / 20 of the time, this coin flip was what we call a "success" (meaning that it matches the guidelines that we want)

4 / 20 = 20% of the time

So, the probability of a group of 4 puppies being 3 females and 1 male is :

4 / 20 (1 / 5)

20%

Tickets for a play at the community theater cost $8 for children and $20 for adults. A total of 300 tickets have been sold for $
salantis [7]

Answer:

125 adults

175 children

Step-by-step explanation:

3900=8c+20a

300=c+a

c=300-a

substitute

3900=8(300-a)+20a

reduce

3900=2400-8a+20a

1500=12a

a=125 adults

substitute for a

c=300-a

c=300-125

c=175 children

One kilogram is 2.2 pounds. If i had 1 pound would that be 0.45 kilograms why or why not?
prisoha [69]

Step-by-step explanation:

1 kg = 2.2 pounds

0.45 kg = 1 pounds to see whether it's correct or not we can cross multiply the given equations

multiply 1 kg with 1 pounds and 0.45 kg with 2.2 pounds then check if they are equal

1 × 1 = 2.2 × 0.45

1 = 0.99 as you can see this is not an equality therefore the statement is wrong.
