Question The distribution of course grades in a very large class is (approximately) Normal with mean 49 and standard deviation 10. The minimum possible grade is 0 and the maximum possible grade is 120. The course instructor is considering the possibility of a "bell curve" that will increase the mean grade to 78 and decrease the standard deviation to 6. Suppose the bell curve is applied and Zeus' grade stays the same. What is Zeus' grade?

What do you notice? Compare and contrast the growth rates for the states. How do you think these growth rates will impact government allocations for each state?Determine an exponential model for the states with the two fastest growth rates. Explain your work. Note: The y-intercept equals the value provided for 1910. Thus, for the year 1910, x = 0.

Learning Goal: To use the force method of analysis to calculate the reaction forces for a statically indeterminate axially loaded member. The steel member shown below has a diameter of 85 mm modulus of elasticity of E = 200 GPa and is fixed at A and B. The support at A is rigid, but the support at B can be considered rigid only if the reaction force at B does not exceed 150 kN. The lengths are LAB = 6.5 m and LAC = 2.4 m. Part A-Determine the maximum load What is the maximum load. P. that can be applied such that the reaction at B does not exceed 150 kN ? Express your answer to three significant figures in kN.

Show all work and explain. The rigid bar is supported by the two short white spruce wooden posts and a spring. 50 kN/m А с B k 1 m -1 m -1 m Part A If each of the posts has an unloaded length of 1 m and a cross-sectional area of 850 mm² , and the spring has a stiffness of k = 4 MN/m and an unstretched length of 1.02 m , determine the force in each post after the load is applied to the bar. Express your answer to three significant figures and include appropriate units.

Please write each number in front of the resultthank you. Shelly and Kelly Macdonald met up with Sarah and Tara MacNeill to go fishing in Cape Breton. They found two pools in a stream containing speckled trout (assume equal variance), with the Macdonalds at one pool and the MacNeills at the other, and at the end of the day each team had caught (and released unharmed) 5 fish.
