1 In a graduate teacher college, a survey was conducted to determine the proportion of students who want to

major in Mathematics. If 378 out of 900 students said Yes, with 95% confidence, what interpretation can we

make regarding the probability that all students in the teacher graduate college want to major in Mathematics.

1. Apply your mathematical models to your allocated car. Use the given data for the 0 – 28 m/s and 400m times to calculate the:

1. value of the coefficient A

2. maximum velocity

3. maximum acceleration.

Given: t (0-28 m/s) is 1.9s, t (400m) is 10.50s & tmaxspeed is 7.1s.

Given velocity equation :V (t) = A (1 - e^((-t)/(t maxspeed)))

i need step by step solution to understand

according to its label, each coffee bag in a box contains 4g of coffee powder.in actual fact, the mass of coffee powder per bag has a mean 4.05g and a standard deviation of 0.05g. assuming that the mass of coffee powder in each bag is distributed normally, calculate the expected number of coffee bags which contain 3.95g to 4.10g of coffee powder in a box of 300 bags.
