Here is the graph. Work is shown in the picture. I hope this helps.
Answer:
Yes, the marketing manager's claim is true.
Step-by-step explanation:
p = 0.61
Phat = 545 /826 = 0.66
H0 : p = 0.61
H1 : p ≠ 0.61
The test statistic :
(Phat - p) / √pq/n
q = 1 -p = 1 - 0.61 = 0.39
(0.66 -0.61) / √(0.61*0.39)/826
0.05 / 0.0169709
Test statistic = 2.95
Using the p-value from Zscore calculator:
Pvalue at 2.95, two tailed ;
Pvalue = 0.0032
Reject H0; if Pvalue < α
Since, Pvalue < α ; Then, the marketing manager's claim is true
Answer:
9
Step-by-step explanation:
If this is referring to plots on a grid the answer would be positive since your just counting the distance and its not an actual equation. 1 negative space plus 8 positive spaces equals 9
Answer:
A) Sum of angles in the 14-gon = ![2160^{o}](https://tex.z-dn.net/?f=2160%5E%7Bo%7D)
B) Sum of angles in the 16-gon = ![2520^{o}](https://tex.z-dn.net/?f=2520%5E%7Bo%7D)
Step-by-step explanation:
Convex polygon is one that has the value of its internal angles less than the sum of angles in a triangle. That is each interior angle is less than
.
Sum of angles in a polygon = (n - 2) x ![180^{o}](https://tex.z-dn.net/?f=180%5E%7Bo%7D)
where n is the value of its number of sides.
So that;
A) 14-gon (which has 14 sides),
Sum of angles in the 14-gon = (14 - 2) x ![180^{o}](https://tex.z-dn.net/?f=180%5E%7Bo%7D)
= 12 x ![180^{o}](https://tex.z-dn.net/?f=180%5E%7Bo%7D)
= ![2160^{o}](https://tex.z-dn.net/?f=2160%5E%7Bo%7D)
The sum of the measure of the interior angles of the 14-gon is
.
B) 16-gon (which has 16 sides),
Sum of angles in the 16-gon = (16 - 2) x ![180^{o}](https://tex.z-dn.net/?f=180%5E%7Bo%7D)
= 14 x ![180^{o}](https://tex.z-dn.net/?f=180%5E%7Bo%7D)
= ![2520^{o}](https://tex.z-dn.net/?f=2520%5E%7Bo%7D)
The sum of the measure of the interior angles of the 16-gon is
.
