Answer: 0.2224
Step-by-step explanation:
Given: The proportion of adults need eye correction: p= 78%=0.78
Let X be a binomial variable that represents the number of adults who need eye correction.
Sample size of adults: n= 12
Binomial ditsribution formula:
Now, the probability that at least 11 of them need correction for their eyesight will be
Hence, the required probability = 0.2224
51,000
5 in the ten thousands,
The thousands value is 1, the hundreds is 4 (less than 5 so we round down)
Answer:
4x - 3 + 2y) - (-4y + 2) = 4x - 5 + 6y
Divide the monthly cost by the number of minutes:
$42 / 1594 = 0.026
Rounding to the tenths would be the first place to the right of the decimal which would be 0.00
Cents are usually rounded to the hundredths place, which would be $0.03 per minute.
