A box plot is shown. The left-most point on the plot is 20 and the right-most point is 95. The box is labeled 37.5 on the left edge and 60 on the right edge. A vertical line is drawn inside the rectangle at the point 50. Calculate the interquartile range of the data, and explain in a sentence or two what it represents.

Step-by-step explanation:

Well we need to know the atomic weight of Platinum (Pt) and the number of atoms per mole. The answer to the former is 195.084 g/mole and the latter is 6.023×10^23 atoms/mole. Then, multiply everything as shown below:

Number of atoms = (1 g)×(1/195.084 g/mole)×6.023×10^23 atoms/mole

Number of atoms = 3.087×10^21 atoms.

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
