Answer:
59 million
Step-by-step explanation:
Due to the way exponents work, we first take that the difference from 2002 to 2010 is 4/5 the difference from 1992 to 2002. The total amount that the population is in 2002 compared to 1992 is 1.15. 1.15^(4/5)*53 million is roughly 59 mil :)
Step-by-step explanation:
x^2+4x=0
therefore x=-4
Answer:
The values of a and b are -1.28 and 1.28 respectively.
Step-by-step explanation:
It is provided that the area of the standard normal distribution between a and b is 80%.
Also it is provided that a < b.
Let us suppose that a = -z and b = z.
Then the probability statement is
Simplify the probability statement as follows:
Use the standard normal distribution table to determine the value of <em>z</em>.
Then the value of <em>z</em> for probability 0.90 is 1.28.
Thus, the value of a and b are:
Thus, .
Answer:
48 square units
Step-by-step explanation:
Let the length of the rectangle be x units.
By Pythagoras theorem:
Length of rectangle = 8 units
Area of rectangle
= Length * width
= 8 * 6
= 48 square units
