Here we shall use the binomial distribution formula to evaluate the probability:
let the probability that the temp will be above 80 be P(F)=2/3;
Probability that the temp will be below 80 be P(F')=1/3
thus,
The probability that the temp will be above 80 for 20 days for the month of June will be:
P(F)=n!/((n-x)!x!)p^xq^(n-x)
p=2/3 and q=1/3, n=30, x=20
plugging the values in the equation we obtain:
P(F)=30!/(10!*20!)*(2/3)^20*(1/3)^(30-20)
P(F)=0.153
Answer:
The car was moving approximately at a speed of 37.74 miles per hour.
Step-by-step explanation:
We are given the following in the question:
The stopping distance of a car is given by
where d is the stopping distance in feet and r is speed of the car in miles per hour.
The stopping distance is 75 feet, we have to find the speed of the car,
Putting d = 75 in the equation, we get,
Thus, the car was moving approximately at a speed of 37.74 miles per hour.
Answer:
6 centimeters and 4 centimeters
Step-by-step explanation:
According to the Triangle Inequality, the sum of the lengths of any two sides of a triangle has to be greater than the third side. The answer choices that satisfy the Triangle Inequality is 6 centimeters and 4 centimeters.
6(f)^0.5
is this what you meant?
