<span>3.15*10^12 would be 3.15 trillion in scientific notation.</span>
The answer is 336 because since combinations are a way to calculate the total calculations so the answer is 336.
Answer:
The probability is 0.9909.
Step-by-step explanation:
Test statistic (z) = (sample mean - population mean) ÷ (sd/√n)
sample mean = 290 days
population mean = 298 days
sd = 22 days
n = 42
z = (290 - 298) ÷ (22/√42) = -8 ÷ 3.395 = -2.36
The cumulative area of the test statistic is the probability that the mean gestation period is less than 290 days. The cumulative area is 0.9909. Therefore the probability is 0.9909.
Answer:
bro si would be 20000 and time would be 1 year because rate is in per annum or per year.
