Answer:
The best estimate for the true proportion of all such students who own a Texas Instruments calculator is 0.3.
Step-by-step explanation:
The estimate of the true proportion of all students who own a Texas Instruments calculator is the number of students who own a Texas Instruments Calculator divided by the total number of students.
6 students own a Texas Instruments Calculator
20 total students
p = 6/20 = 0.3
The best estimate for the true proportion of all such students who own a Texas Instruments calculator is 0.3.
Looking at the graph:
we know that the y-intercept is 4
slope is
we can use (0,4) as point 1 and (6, -4) as point 2 to find the slope
using slope intercept form your answer should be
y=(-4/3)x+4
also, your answers repeat themselves. A and B are the same and so are C and D

75% is 2 hour
then 60% = 60/12.5 = 4.8 hours left
8-4.8 = 3.2 hours there
3.2x 60 = 192 minutes
