Find the experimental probability that exactly 3 of 4

Mathematics
1 answer:
otez555 [7]2 years ago
3 0

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%

Use substitution to solve the system.<br> x=3y+5<br> 5x-4y=14<br> ______________<br> x=<br> y=
nataly862011 [7]
So what you do is go 5(3y+5)-4y=14 which equals 15y+25-4y=14 which turns into 11y+25=14 than you move the 25 over which equals 11y=-11 so y=-1 then you enter -1 in for y which looks like 5x-4(-1)=14 than you solve that which is 5x+4=14 than you move the 4 over and you get 5x=10 than x=2

x=2
y=-1

Suppose AC = 5 cm, BC = 12 cm, and mAC = 45.2°.
DedPeter [7]
Using Pythagoras theorem
|AB|*2=|d/2|=(5*2)+12*2
AB*2=25+144
AB=13
D/2= r=6.5cm

tan¥=6.5/5
tan¥=1.3
¥=tan inverse of (1.3)
¥=52.43 degrees
