Number of remaining rose cards = 6
number of remaining cards = 8
P(rose card) = 6/8
P(blue marble) = 18/50
P(tail) = 30/50
P(blue marble and tail) = 18/50 x 30/50 = 540/2500
Answer:
a = ±b
Step-by-step explanation:
The vertical bars are the symbol for "absolute value", so the equation is saying, "the absolute value of 'a' is equal to the absolute value of 'b'." The absolute value is the magnitude of a number, so, for example, |-3| = 3.
If the magnitudes of two numbers are the same, they may be the same value, or they may differ in sign.
6. B
9. B
For number 6, 10 vans times 12 students is 120 students. 432 - 120 = 312. 312 students divided by 6 buses is 52. To check if it right I tried Middle School B. 5 vans times 12 students is 60. 164 students - 60 = 104. 104 divided by 2 buses equals 52. So 12 students is the right answer.
For number 9, 35*2=70 and 15*5=75. 70+75=145.
