A:
1 day = 1/8 of work
B:
1 day = 1/24 of the work
Together:
1 day = A + B = 1/8 + 1/24 = 4/24 = 1/6
1 day = 1/6 of work
1/6 x 6 of work = 1 x 6 days
work = 6 days

29.3 ounce package- $3.67
It is better to buy a 10.5 ounce package
Okay so we can convert all of the numbers into the same unit so we can compare
jamail = 29.4%
andrew = 37.6%
ernesto = 28%
blake = 30%
in order from greatest to least,
andrew
blake
jamail
ernesto
Answer:
The probability that a performance evaluation will include at least one plant outside the United States is 0.836.
Step-by-step explanation:
Total plants = 11
Domestic plants = 7
Outside the US plants = 4
Suppose X is the number of plants outside the US which are selected for the performance evaluation. We need to compute the probability that at least 1 out of the 4 plants selected are outside the United States i.e. P(X≥1). To compute this, we will use the binomial distribution formula:
P(X=x) = ⁿCₓ pˣ qⁿ⁻ˣ
where n = total no. of trials
x = no. of successful trials
p = probability of success
q = probability of failure
Here we have n=4, p=4/11 and q=7/11
P(X≥1) = 1 - P(X<1)
= 1 - P(X=0)
= 1 - ⁴C₀ * (4/11)⁰ * (7/11)⁴⁻⁰
= 1 - 0.16399
P(X≥1) = 0.836
The probability that a performance evaluation will include at least one plant outside the United States is 0.836.
