Answer:
Therefore the required value of x,

Step-by-step explanation:
Given:
ΔBC is a Right Angle Triangle at ∠ B = 90°
As ∠ B = 90° , AC will be the Hypotenuse
AC = 10 = Hypotenuse
BC = y = Longer leg ( say )
AB = x = Shorter leg ( say )
To Find :
x = ?
Solution:
In Right Angle Triangle Δ ABC , By Pythagoras Theorem we get

Substituting the given values we get

Therefore the required value of x,

Answer:
(-6,0)
Step-by-step explanation:
the y-axis is any (x number, 0)
Answer:
1.165.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so 
Now, find the margin of error M as such

In which
is the standard deviation of the population and n is the size of the sample.
In this problem, we have that:
. So


So the correct answer is:
1.165.
