The average speed of the snowmobile can be obtained by using the formula: speed = distance/time which was also given in the problem statement. This means that the average speed refers to how far you have traveled in a period of time. In this case, the snowmobile traveled 32 miles in 213 hours. We then simply divide the distance, 32 miles, by the time it took for the snowmobile to travel such distance which is 213 hours. The average speed of the automobile is calculated to be 0.1502 miles per hour. When rounded off to the nearest tenth, the final answer is then 0.2 miles per hour.

30 feet is correct. Since a = 3b, the wingspan is 6 inches in the drawing, so it is 6x5 = 30 feet on the plane.
Answer:
14
-25/1
Step-by-step explanation:
A) See picture for the table.
To make the table, multiply 47774 by 1.5% to get total that have diabetes and multiply 5855 by 2.5% to get total unemployed that have it, then using subtraction fill in the other squares of the table.
B)
Hypothesis:
H0: No association between employment and diabetes.
H1: Association between the two
Using a graphing calculator or Excel, run a chi-test.
Chi squared equals 31.844 with 1 degrees of freedom.
The two-tailed P value is less than 0.0001
With this information we can reject the null hypothesis and conclude there is an association between diabetes and employment.
C)
Although there is a statistical significance, there really is no practical significance between an incidence rate of 1.5 or 2.5%
