Answer:
its 23
Step-by-step explanation:
its 12+11 because two negatives make a positive
Answer:
A=950
B=540
Step-by-step explanation:
Answer:
500π ≈ 1570.796
Step-by-step explanation:
diameter = 10
radius = diameter / 2 = 10 / 2 = 5
height = 4 * radius = 4 * 5 = 20
volume = π * height * (radius)² = π * 20 * (5)² = 500π ≈ 1570.796
Let Xi be the random variable representing the number of units the first worker produces in day i.
Define X = X1 + X2 + X3 + X4 + X5 as the random variable representing the number of units the
first worker produces during the entire week. It is easy to prove that X is normally distributed with mean µx = 5·75 = 375 and standard deviation σx = 20√5.
Similarly, define random variables Y1, Y2,...,Y5 representing the number of units produces by
the second worker during each of the five days and define Y = Y1 + Y2 + Y3 + Y4 + Y5. Again, Y is normally distributed with mean µy = 5·65 = 325 and standard deviation σy = 25√5. Of course, we assume that X and Y are independent. The problem asks for P(X > Y ) or in other words for P(X −Y > 0). It is a quite surprising fact that the random variable U = X−Y , the difference between X and Y , is also normally distributed with mean µU = µx−µy = 375−325 = 50 and standard deviation σU, where σ2 U = σ2 x+σ2 y = 400·5+625·5 = 1025·5 = 5125. It follows that σU = √5125. A reference to the above fact can be found online at http://mathworld.wolfram.com/NormalDifferenceDistribution.html.
Now everything reduces to finding P(U > 0) P(U > 0) = P(U −50 √5125 > − 50 √5125)≈ P(Z > −0.69843) ≈ 0.757546 .
For blank 1:
$14 for 4 pounds. so 84/14= 6, then 6x4= 24. 24 pounds of apples
For blank 2:
If an apple is approx 5 ounces, 16/5 isn't a whole number, but 15/5 is, so 3, There are about 3 apples in each pound
For blank 3:
3 apples in each pound, and you can buy 24 pounds, 3x24=72
