For a known standard deviation, the confidence interval for sample size = n is
where
x = average
n = sample size
= stad. deviation
z = contant that reflects confidence interval
Let a = x
Let b =
From the given information,
a - b = 0.432 (1)
a + b = 0.52 (2)
Add (1) and (2): 2a = 0.952 => a = 0.476
Subtract (2) from (1): -2b = -0.088 => b = 0.044
Therefore, the confidence interval may be written as
(0.476 - 0.044, 0.476 + 0.044), or as
(0.476
0.044)
Since they are like terms you will combine them.
16 - 5 = 11z
So your answer is A) 11z.

Answer:
$73.21
Explanation:
where A is final value, P is initial value, r is rate of interest, t is time (years)
Solve for Final Value:
A rhombus is a parallelogram, namely, is a polygon with four sides and two pairs of parallel sides.
the one distinction of a rhombus with other parallelograms is that, a rhombus has all equal sides, all its four sides are the same length, so, if you already know the vertices are for a parallelogram, then is a given two pairs of sides are parallel.
so... you simply need to check their length, making sure they're all equal, using the distance formula.
