Answer:
Both figures are rhombuses, they have the same angle degrees, one is just slanted more and smaller than the other.
These statistics are impossible: all students who ride bike and use crossing guard ride a bike, so the proportion of students who ride a bike and use the crossing guard must be less than or equal to the proportion of students who ride a bike. This is not true in the given stats; 0.12 > 0.1
Answer:
The upper boundary of the 95% confidence interval for the average unload time is 264.97 minutes
Step-by-step explanation:
We have the standard deviation for the sample, but not for the population, so we use the students t-distribution to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 35 - 1 = 35
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 34 degrees of freedom(y-axis) and a confidence level of ). So we have T = 2.0322
The margin of error is:
M = T*s = 2.0322*30 = 60.97
The upper end of the interval is the sample mean added to M. So it is 204 + 60.97 = 264.97
The upper boundary of the 95% confidence interval for the average unload time is 264.97 minutes
Answer:
The absolute maximum and minimum is
Step-by-step explanation:
We first check the critical points on the interior of the domain using the
first derivative test.
The only solution to this system of equations is the point (0, 4), which lies in the domain.
is a saddle point.
Boundary points -
Along boundary
Values of f(x) at these points.
Therefore, the absolute maximum and minimum is
The equation you want to use is this:
10x = 530 10 pages for x days
x = 530/10 530 pages divided by 10 pages
So the answer is,
53 days
