On problems ii, and iii, you just count up the amount of sides on the polygon and add x behind it to create a type of an equation to find the perimeter of that shape that will work as longs as the sides are congruent to each other.
For problems a,b, and c, you just have to calculate what x is. On a, you find what the other side is if one side is 2 and the area is 24. On b you find what the other side could equal if one side is 4 and the area is 16. On c you know what the perimeter is (72) . The longer sides are 2x and the shorter sides are x. SO you divide by the #s and check your work!
Recognize that you must combine "like" terms. 5x^2y and x^2y are "like" terms.
Adding them together, you get 6x^2y.
Now add 2xy^2 to 6x^2y. These are NOT "like" terms, so you end up with
6x^2y+2xy^2 as your final answer. This answer is acceptable as is.
However, you could factor out the common factors: 2xy(3x+y).
Option D: 
is the inverse of the function f(x) = 4x
Explanation:
Given that the function is 
We need to determine the inverse of the function.
<u>Inverse of the function h(x):</u>
The inverse of the function can be determined by interchanging the variables x and y and then solving the function for y.
Thus, the function is written as,
Interchanging the variables x and y, we have;
Dividing both sides by 4, we get;
Thus, the inverse of the function is
Hence, Option D is the correct answer.
If it is 8/8464, it is 0 remainder 8
If it is 8464/8, it doesn’t have remainders. It is 1,058.

Answer:
(0.55, 0.75)
Step-by-step explanation:
The standard deviation and range are both used to measure the spread of a data set. The number of the range and standard deviation gives us information in its own way how spaced out the data are due to the fact that they are both a measure of variation. However, there is not an explicit relationship between the range and standard deviation, there is a rule of thumb that can be useful to relate these two statistics. This relationship is sometimes referred to as the range rule for standard deviation.
The range is estimated to be 6 standard deviations wide. Therefore, the standard deviation is:
Standard deviation= maximum sample proportion - minimum sample proportion / 6
σ = (0.72 - 0.42) / 6
σ = 0.05
The margin of error is defined as a statistic showing the amount of random sampling error in the result of a survey. The greater the margin of error, the lesser the confidence that a poll result would reflect the result of a survey of the entire population.
Here, the margin of error is ±2σ, so:
ME = ±0.10
Interval estimation in statistics is the use of sample data to compute an interval of possible values of an unknown population parameter. This is therefore in contrast to point estimation, which gives a single value.
Therefore, the interval estimate is:
(0.65 - 0.10, 0.65 + 0.10)
(0.55, 0.75)
