Answer:
0.2776
Explanation:
Mean = 15000, SD = 1500
We need to find Cumulative probability: P(X > 15884)
First we need to convert it into normal distribution.
From the attached file, we can see the shaded area we are looking for.
For conversion as follow; 
Next to find Z = 
= 0.59
now we have converted to normal distribution and found the value of Z, we need to find the probability P(X > 15884).
P(X > 15884) = P(Z > 0.59).
From the normal distribution table at Z= 0.59, and greater than 0.59, Probability = 0.2776.
It will most likely be on record and can inspire new hypotheses.
Or the Third Option
Answer:
The molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate into 355 mL of water is 0.9881M
Molarity of solution is the ratio of the number of moles of the substance to the volume.
n is the number of moles of the compound
Mass of calcium nitrate = 54.3g
Molar mass of calcium nitrate = Ca(NO₃)₂ = 164.088 g/mol
Get the required molarity;
Hence the molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate into 355 mL of water is 0.9881M

Parallelograms are shapes that have 4 sides, where the opposite sides are congruent and parallel
<h3>How to determine a parallelogram</h3>
For a shape to be a parallelogram, then the following must be true
- The opposite side lengths are congruent
- The opposite side lengths are parallel
- The diagonals bisect each other
<h3>The proof statement</h3>
The above statements in (a) above mean that:
The statements that prove that quadrilateral uwxy is a parallelogram are
- Diagonals UX and WY bisect each other
- Sides UW and XY are congruent
- Sides UW and XY are parallel.
