Answer:
Adults: 75, girls: 100, Boys: 75
Step-by-step explanation:
2/5 x 250 = 100( girls)
3/10 x 250 = 75 (boys)
250 - (100 + 75) = 250 - 175 = 75 (Adults)
The probability of rolling an odd number or a number less than 5 is 5/6.
Probability is the likelihood of the occurrence of an event. It is the ratio of number of events to number of possible outcomes.
The possible outcome from rolling a six-sided die is 1, 2, 3, 4, 5 and 6
P(odd number) = 3/6; P(less than 5) = 4/6; P(odd number and less than 5) = 2/6
Hence:
P(odd number or less than 5) = 3/6 + 4/6 - 2/6 = 5/6
The probability of rolling an odd number or a number less than 5 is 5/6.
2a-8a=12-8a
now add 8a to both side and you get
2a= 12
divide both sides by 2 and you get
a=6
X would equal 60 degrees because the degree of the top left area is equal to the degree of the bottom right. So the equation would be x+20=80 so you would solve to get x=60
Answer:
x = 2
Step-by-step explanation:
Rewrite the equation as 4x - 6 = 2
Move all terms not containing x to the right side of the equation:
Add 6 to both sides of the equation.
4x = 2 + 6
Add 2 and 6.
4x = 8
Divide each term by 4 and simplify.
Divide each term in 4x = 8 by 4.

Reduce the expression by cancelling the common factors.

Divide 8 by 4.
x = 2
