Answer:
(-3.07, 11.07)
Step-by-step explanation:
Given that a sports writer wished to see if a football filled with helium travels farther, on average, than a football filled with air. To test this, the writer used eighteen adult male volunteers. These volunteers were randomly divided into two groups of nine subjects each.
Group Group One Group Two
Mean 300.00 296.00
SD 8.00 6.00
SEM 2.67 2.00
N 9 9
The mean of Group One minus Group Two equals 4.00
standard error of difference = 3.333
df = 16
t = 1.2000
Margin of error = 3.3333* t critical = 3.3333*2.121
95% confidence interval of this difference: From -3.07 to 11.07
Answer:
I'm pretty sure X and Y intercept! I may not be correct though
Answer:
dm
Step-by-step explanation:
A square's diagonal cuts across the square, making two right triangles where the diagonal is the hypotenuse.
We have a right triangle with a hypotenuse of 29, and two legs that are the same length (because they are sides of a square)
So, we can use pythagoreans theorem to find the lengths of the legs, or sides of the square.
Now that we have a side length of 
, we just have to multiply that by 4, since a square has 4 sides. This leaves us with a final perimeter of:
Total Volume is given as 1080 cubic feet.
Height is given as 9 feet.
Length is 2 feet longer than the width, so Length = x+2
If the stall is 10 feet wide, then the length would be 10 +2 = 12 feet.
The volume for that would be 10 x 12 x 9 = 1080 cubic feet.
Yes it is possible for the width to be 10 feet.
Answer:
A = 13 degrees
B = 65.3 degrees
C = 180 - (13 + 65.3) = 101.7 degrees
Side a = 35 km
Side b = 141.4 km
Side c = 152.4 km
