2022年4月28日 · How many minutes equals 7 hours? How many minutes in one hour? Multiply that number by 7.1 hour = 60 minutes7 hours = (7 x 60) = 420 minutesThere are 420 minutes in 7 hours.1hour=60 minutes7x60 ...

60 mph = 1 mile per minute so the truck is 7 miles ahead The car gains on the truck at 11 mph (71-60) It will take 7/11 hours to overtake the truck = 7*60/11 minutes =~ 38 minutes-----Your solution of 45 minutes is the time starting when the truck entered the highway.

Question 1154909: Assume the random variable x is normally distributed with mean = 50 and standard deviation = 7. Find the indicated probability P(x>39) Find the indicated probability P(x>39) Answer by Boreal(15235) ( Show Source ):

You can put this solution on YOUR website! Let the number of dimes be x Let the number of quarters be y Value Value Type Number of of of of EACH ALL coin coins coin coins ----- dimes x $0.10 $0.10x quarters y $0.25 $0.25y ----- TOTALS 40 ----- $7.60 The first equation comes from the second column.

Question 675224: Assume that X has a normal distribution, and find the indicated probability. The mean is μ = 60.0 and the standard deviation is σ = 4.0. Find the probability that X is less than 53.0. Answer by stanbon(75887) (Show Source):

x + y >= 70 becomes 35 + 60 >= 70 which becomes 95 >= 70 which is true. x >= 0 and y >= 0 are both also true. all constraint have been satisfied so the least cost solution is (35,60) which means that you would use 35 liters of solution A and 60 liters of solution B.

* We want to find the weight *x* such that P(X > x) = 0.30. This means that 70% of the weights are *below* this value. * Find the z-score corresponding to a cumulative probability of 0.70. Using a z-table or calculator, we find that z ≈ 0.52. * Use the z-score formula to find the weight: x = μ + zσ x = 370 + (0.52 * 15) x = 370 + 7.8

Question 1168050: A population of values has a normal distribution with μ=219.7 and σ=53.7. You intend to draw a random sample of size n=14. Find the probability that a single randomly selected value is greater than 248.4. P(X > 248.4) = Incorrect Find the probability that a sample of size n=14 is randomly selected with a mean greater than 248.4.
