Answer:
22 ft^2
Step-by-step explanation:
The area of a table with diameter 6 ft
A = pi r^2 = pi (6/2) ^2 = pi 3^2 = 9pi
The area of a table with diameter 8 ft
A = pi r^2 = pi (8/2) ^2 = pi 4^2 = 16pi
Subtract 16pi-9pi = 7pi
Using 3.14 for pi
7 * 3.14
21.98 ft^2
To the nearest square foot
22 ft^2
Answer:
All you have to do is equal the equations to each other to find x for each problem!
Step-by-step explanation:
Hope this helps bestieee!
5x divided by 5
18 divided by 5
X= 18/5 or 3.6
Step-by-step explanation:
H0 : µ ≤ 26.9
Ha : µ > 26.9
a. since the null hypothesis is rejected, we would accept the alternative hypothesis and come to the conclusion that there is enough evidence that beer and cider consumption are higher than 26.9 in the city.
b. type 1 error happens when we reject a true null hypothesis.
this error error in this question would be that our conclusion that beer and cider consumption is greater than 26.9 is not true. what is true is that it is equal to or less than 26.9.
the consequence is that is h0 is false it would be harder to reject it at a lower level of significance.
c. type ii error happens when the null hypothesis is accepted even though it is false. here, error would be that cider we accepted that cider and beer consumption is less than or equal to 26.9 when it is actually greater than 26.9
the consequence is that it would be harder to accept a true h0 at a high level of significance
