Determine the area under the standard normal distribution curve between -0.91 and 2.5.
The Smith Trucking Company claims that the average weight of its delivery
trucks when fully loaded is 6000 pounds with a standard deviation of 120
pounds. 36 trucks are selected at random and their weights recorded.
Within what limits will the average weights of 90% of the 36 trucks lie?
a group of student got the following scores in an achievement test 9,12,15,18,21 and 24. consider samples of size 3 that can be drawn from this population.
A twin-engine aircraft has an engine failure shortly after takeoff at sea level. The pilot tried to turn back
toward the field by making a left-hand turn but crashes after making a 180-degree turn. The wreckage
diagram shows that the turn radius was 3,800 feet. From the radar tapes, the airspeed is estimated to be 160
knots during the turn. The level, steady stall speed of this aircraft is 135 knots.
What is the steepest allowable bank angle with out the aircraft stalling while performing a turn in the
horizontal plane at 160 knots? Please round your answer rounded to the full degree.
Swap Competition
An English competition is being held where players have to play in groups of two. One of the players is given a word, and the second player has to choose a word such that, it is a rearrangement of the letters in the first player's word. They win if the above condition is satisfied. The number of groups is given by T.Write a programthat gives YES if they win and NO in the other case.
Note: All characters in the input will be in lower case.
Input

A class called MyPoint, which models a 2D point with x and y coordinates. It contains:
Two private instance variables x (int) and y (int).
A constructor (__init__()) that constructs a point with the given x and y coordinates.
Getter and setter for the instance variables x and y.
Method setXY() to set both x and y.
Method getXY() which returns the x and y in a 2-element list.
A __str__ method that returns a string description of the instance in the format "(x, y)".
Method called distance(self, anotherpoint) that returns the distance from this point to the given MyPoint instance (called another), e.g.,
p1 = MyPoint(3, 4)
p2 = MyPoint(5, 6)
print(p1.distance(p2))
Method called distance_from_origin() method that returns the distance from this point to the origin (0,0), e.g.,
p1 = MyPoint(3, 4)
print(p1.distance_from_origin())
The production manager of a large manufacturing company estimates that the mean age of his employees is 22.8 years. The treasurer of the firm needs a more accurate employee mean age figure in order to estimate the cost of an annuity benefit program being considered for employees. The treasurer takes a random sample of 70 workers and finds out that the mean age of the employees sampled is 26.2 years with a standard deviation of 4.6 years. At the 0.01 level of significance, what can the treasurer conclude about the accuracy of the production manager’s estimate?
An 88.5 –g piece of iron whose temperature is 78.8 0 C is placed in a beaker containing 244 g of water at 18.8 0 C.
When thermal equilibrium is reached, what is the final temperature? (Assume no energy is lost to warm the
beaker and its surroundings). Cp of water is 4.184 J/g0C and the Cp of iron is 0.446 J/g 0C.
Write the equilibrium expression, K eq , for each of the following reactions:
1. 2 NO (g) + O 2(g) ⇌2 NO 2(g)
2. 4 HCl (g) + O 2(g) ⇌2 H 2 O (g) + 2 Cl 2(g)
3. NOCl (g) ⇌NO (g) + ½ Cl 2(g)
4. Fe 3+ (aq) + SCN - (aq) ⇌FeSCN 2+ (aq)
5. CaCl 2(s) ⇌Ca 2+ (aq) + 2Cl - (aq)
6. HC 2 H 3 O 2(aq) + H 2 O (l) ⇌ H 3 O + (aq) + C 2 H 3 O 2 - (aq)
7. MgO (s) + CO 2(g) ⇌ MgCO 3(s)
8. C (s) + CO 2(g) + 2Cl 2(g) ⇌ COCl 2(g)
9. Ca 3 (PO 4 ) 2(s) ⇌ 3 Ca 2+ (aq) + 2 PO 4 3- (aq)
10. ZnO (s) + CO (g) ⇌ Zn (s) +CO 2(g)
