Answer:
5 centimeters of snow per hour.
Step-by-step explanation:
We are given an equation d = 5h, where d = depth of snow and h = hours of the snowstorm.
We need to find the number of centimeters of snow that accumulate in 1 hour.
In order to find the number of hours that accumulate the snow to 1 centimeter, we need to plug d=1 in the given equation.
On plugging d=1, we get
1= 5h.
Dividing both sides by 5, we get
1/5 = h.
Therefore, it would take 1 hour for 5 centimeters of snow to accumulate in Harper's yard.
10 minutes is 1/6 of an hour.
1 hour and 10 minutes = 7/6 hours
98 km / 7/6 = 98 x 6/7 = (98 x 6) /7 = 588/7 = 84 km per hour
Answer:
The correct answer is option 'a' : 120 is more than 2.5 standard deviations above the expected value.
Step-by-step explanation:
For an exponential distribution we have
The expected value μ = 80
No of trails n = 200
Thus we have

The deviation is related to expected value and probability as

Thus the values between the given deviation is

Now since 120 successes are out of the range of [62.75,97.25] thus 120 is more than the expected value.

Step-by-step explanation:
Sqrt -13 = sqrt13 i
sqrt -26 = sqrt2 * sqrt13i
sqrt-13 * sqrt -26 = sqrt2 * 13* i^2 = -13 sqrt2 (because i^2 = -1)
answer is -13 sqrt2
