Answer:
or
Step-by-step explanation:
we know that
Applying the Pythagorean Theorem in the rectangular pool
where
d is the diagonal of the pool
L is the length of the pool
W is the wide of the pool
we have
substitute the given values
solve for L
simplify
or
Mean = 133.9
then calculate the z value
with z value you will find out the p value on a table.
if the p value is below .05 reject the null hypotheses
Answer:
12 + 24 = 2(6 + 12)
Step-by-step explanation:
hope this helpss :D
much appreciated if this were marked brainliest <3
Form a right angle triangle joining both given points to the origin, we get:
Perpendicular = 2 ( distance is always positive)
Base = 4 ( same logic)
Applying Pythagorus theorem
Hypotenuse = root of ( perpendicular squared + base squared)
Hypotenuse = root of 20 = 2 * root 5
Using x instead of theta
Sin x = perpendicular/hypotenuse
Cos x = base/hypotenuse
Sin x = -1/ root 5
Cos x = -2/ root 5
High probability of this answer being wrong.
Double check recommended.
Yes i is the time of the day you get to frost the moon and back and then you can come over and then go to hang out with me me and then go to hang out over www
