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%
Step-by-step explanation:
4325 * 32 = 138,400
5492 * 44 = 241,648
I have provided work to show how you would complete these problems. The work will be found in the attachments below.
Step-by-step explanation:
(X+3)(2x_9)
3x+12_12=90_12
3x=90_12
3x=78
X=26°
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
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.
