Answer:
2/7
Step-by-step explanation:
There are 22 (12 + 10) total students in the class. That means that the chance of the first student picked being a girl is 12/22.
Now, we must calculate the chance of the next student to be picked <em>also </em>being a girl - however, there is a trap here! Remember that since a girl has been picked, the total student pool has decreased to 21 and and the total number of girls has decreased to 11. This means the new chance of girl being picked is 11/21.
To find the probability of both these events happening in conjunction, these fractions must be multiplied. 12/22 * 11/21 = 132/462, which simplifies to 2/7.
Answer:
240
Step-by-step explanation:
115x4=460
700-460=240
Now, if the diameter is 6 inches, then that means the radius is half that, or 3.
check the picture below.
Answer:
y= 16
Step-by-step explanation:
For numerator 3 to become 12, the numerator and denominator must be multiplied by 4. 3x4=12 and 4x4=16. this claim is correct since 3/4 = 12/16. Taking this into consideration the value of Y is the same as the value of the second denominator.
50 - 40x ≥ 200
-40x ≥ -300
x ≤ 7.5
40$ can be withdrawn from the account 7 weeks if she wants to maintain a balance at least 200<span />
