<span>The volume of 100 pages of the book is 20 in</span>³<span>.
Explanation:
Since the book is rectangular, we use the formula for the volume of a rectangular prism: V = l*w*h.
Using the measurements of the book we have
V = 10*8*(3/4) = 80*(3/4) = 240/4 = 60 in</span>³<span>.
However, 100 out of 300 pages means we want 100/300 = 1/3 of the book: 60(1/3) = 60/3 = 20 in</span>³<span>.</span>
Answer:
x
Step-by-step explanation:
15/35 = y/84
to find what value of y makes the proportion true, you actually just need to solve for y.
15/35 = y/84 ... first, multiply both sides by 84
(15*84)/35 = y
1260/35 = y
36 = y
so, these values are proportional when y = 36. you can check this by getting the decimal of both and seeing if they're equal:
(15/35) = 0.428
(36/84) = 0.428
a−b+c−d−g+2.718282 is the solution for this equation.
What measure of spread is used when your data distribution is symmetrical?
Answer: When the data distribution is symmetrical, the appropriate measure of spread is standard deviation. The reason is both sides of symmetrical distribution will have same spread.
Symmetrical distribution: Symmetrical distribution is one when both sides of the distribution are identical. The symmetrical distribution is bell shaped and mean, median and mode are equal in symmetrical distribution.
Standard deviation: Standard deviation is the measure of dispersion. It measures the deviation of a set of numbers from its mean. It is defined as the square root of means of the squared deviations from the arithmetic mean
