Answer:
- sixty-six millionths
- 0.027
- $12.60
Step-by-step explanation:
(a) The least-significant digit is in the 6th place to the right of the decimal. Numbers in that place have the value "millionths." The number is 66 times 1 millionth, or sixty-six millionths.
__
(b) 27/1000 = 0.027 . . . . the least-significant digit goes in the "thousandths" place
__
(c) The digit to the right of the "cents" place is 5. This is more than 4, so 1 must be added to the cents place when rounding. $12.59 + 0.01 = $12.60.
Answer:
Step-by-step explanation:
The total number of marbles is 20
Question A
P(Red) = 4/20 = 1/5
P(yellow) = 9/20
P(Red then Yellow) = 1/5 * 9/20 = 9 / 100
Question B
P(B) = 6/20
P(B again) = 5/19 because you have 1 less total plus 1 less blue.
P(B and B) = 6/20 * 5/19
P(B and B) = 30/ 380 = 3/38
