Answer: 6/8, 12/16, 15/20, 18/24, are all equal
Step-by-step explanation:
Answer: The probability is 0.013
Step-by-step explanation:
Out of 80 people, 28 of them dance with the hands touching the ground.
Then, the probability of selecting at random someone that dances with the hands touching the floor is equal to the number of persons that dance in that way, divided by the total number of persons.
For the first selection, this is p1 = 28/80
now, the probability in the second selection will be 27/79, because we have selected 1 out of the 28 (and also 1 out of the 80)
for the third and the fourth we have:
p3 = 26/78
p4 = 25/77
Then the probability of the fourth events is equal to the product of the four probabilities:
P = (28/80)*(27/79)/(26/78)/(25/77) = 0.013
if you multiply something by 1/2, the product is half of that something.
if you multiply b by 1/x, the product is one x of b.
if you multiply anything by 1/4, the product is one quarter of anything.
Set up an equation
x+58=4x+37
21=3x
x=7
Jim:

Jesse:
4x+37
4(7)+37
28+37
