Answer:
I
Step-by-step explanation:
sinθ and cosθ and tanθ are all positive in quadrant 1,
since a positive value is divided by a positive value
there is no positive sinθ and cosθ in quadrant 3, so only quadrant 1 is the answer
To solve this you would make a triangle, Assuming you had a piece of paper.
It would look like the picture included (where ever that is) sorry for the horrible drawing with mouse.
You can then you Pythagorean Theorem to solve this
width will be (a)
put in your variables
Subtract 5184 over and get
square root both sides and get
a=54
the field is 54 meters wide
Answer:
Step-by-step explanation:
Given that
Group Group One Group Two
Mean 26.00 23.00
SD 2.00 4.00
SEM 0.40 1.21
N 25 11
where group I represents female servers and group II male servers.
We have to calculate confidence interval for 90% for difference in means
The mean of Group One minus Group Two equals 3.00
df = 34
standard error of difference = 0.993
t critical = 2.034 for 90% df 34
Hence confid. interval at 90%
=Mean diff ±2.034 * std error of diff
= (0.98, 5.02)
