The travel time of 300 students that journey to the University of Manitoba produced the following descriptive statistics:
mean
= 41.67 minutes
standard deviation = 12.37 minutes
Assuming the distribution is normal, use these sample statistics to answer the following questions about
the travel time to the University of Manitoba. Sketch a normal curve and shade the relevant areas in
each problem:
Question 5: What is the probability that students travelled more than 60 minutes to school? (2 marks)

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

the answer is 48m^2!

step-by-step explanation:

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
