A sample size n = 22 is a simple random sample selected from a normally distributed
population. Find the t such that the shaded area to the left of t is 0.05.
Ask the name and roll number of user and then take two float values from user and perform all arithmetic opertaions on them and print the answers.
what is the importance of coupled reactions?
Determine the angular velocity ω of the telescope as it orbits around the Sun.
A ball is thrown from the edge of the top of a building with an initial velocity of 80.3 km/hr at an angle of 52.5 degree above the horizontal. The ball hits the ground a horizontal distance of 108 from the base of the building. Assume that the ground is level and that the side of the building is vertical. Calculate the height of the building.
The position of a particle is given by r(t) = -3.1 t i + 0.72 t4 j m, where t is in seconds. At t = 1.9 s, what is the magnitude of the particle’s acceleration?
At equilibrium, the concentration in moles/L of N2, H2, and NH3 at 300 C are 0.25, 0.15, and 0.90, respectively. Find K, for the reaction
The reaction 2 NO(g) ---- N2(g)+O2(g) has a Kc value of 2400 at 2000 K. If 0.850 M each of N2 and O2 are initially present in a 3.00-L vessel, calculate the equilibrium of No, N2 and O2
Present complete solutions for each item. Illustrate the normal curve if possible.
2. The scores of individual students on a national test have a normal distribution with mean of
18.6 and a standard deviation of 5.9. At Federico Ramos Rural High School, 76 students
took the test. If the scores at this school have the same distribution as national scores, solve
for the following:
a. determine the mean and standard deviation of the sampling distribution of the sample
mean.
b. find the probability that the sample mean falls between 17 and 20 (P(17 < x̅< 20).
c. the number of sample means that is above 19.3 kilograms.
