Answer:
It might be 10 but tell me if I'm right or wrong
Step-by-step explanation:
Answer: 12 Edges
Explanation:
V + F<span> - E = 2
10 + 14 - E = 2
14 - E = 2
E = 14 - 2
E = 12

Answer:
x = 4
y = 13
Step-by-step explanation:
x + y = 17
y = 2x + 5
substitute for y:
x + (2x + 5) = 17
reduce:
3x + 5 = 17
subtract 5 from each side:
3x = 12
divide both sides by 3:
x = 4
y = 2(4) + 5
y = 13
Since there isn't a picture of the graphs, I attached one, of my graph, to this answer.
I'm also assuming (y2 2x+1) is actually (y< 2x+1).
Possible solutions are within the purple section of the attached image.
I hope this is helpful to you.
Answer:
Following are the answer to the given points.
Step-by-step explanation:
In point a:
The confidence interval for p is 95%
using formula:
In point b:
Because 0.22 is not within the trust interval, they have enough proof of H0 at level 0.05.
In point c:
For the percentage for samples,
from ratio p
from sample ratio
In point d:
Standard deviation is used to measure the interval of confidence
