Answer:
- It has taken Jake about 40 minutes to finish his Spanish homework.
Step-by-step explanation:
<u>We know that:</u>
- Homework = 4 hours = Spanish + Math + Science + History
- Spanish = 4 hours x 1/6
- Math = 4 hours x 1/4
- Science = 4 hours x 1/4
- History = 4 hours x 1/3
<u>Work:</u>
- Spanish = 4 hours x 1/6
- => 2 hours x 1/3
- => 2/3 hour
- => 2/3 x 60 minutes
- => 40 minutes
Hence, it has taken Jake about 40 minutes to finish his Spanish homework.
Answer:
They have 69 cookies left.
Step-by-step explanation:
7 x 14 = 98
98 - 29 = 69
Answer:
Step-by-step explanation:
This is a binomial probability distribution because the outcome is either a randomly selected first-class mail within the same city is delivered within two days of the time of mailing or more days. The probability of success, p is that it is delivered within 2 days. Therefore,
p = 95/100 = 0.95
q(probability of success) = 1 - p = 1 - 0.95 = 0.05
n = number of samples = 6
1)The probability that all six arrive within two days, P(x = 6) would be determined from the binomial probability distribution calculator. Therefore,
P(x = 6) = 0.74
2) P(x = 5) = 0.23
3) mean = np = 6 × 0.95 = 5.7
4) Variance = npq = 6 × 0.95 × 0.05 = 0.285
Standard deviation = √0.285 = 0.53
8 675/1000
8 27/40
hope this helps
