Answer:
M
Step-by-step explanation:
A quartic equation/function is a fourth degree polynomial. The general form is:
We can put any values for the variables a, b, c, d, and e.
The general shape of a fourth degree polynomial is in the shape of the English letter "W".
The leading coefficient is the value of "a".
If a is negative, the curve gets upside down, so a "W" going upside down would resemble an "M".
A graph of a quartic with negative leading coefficient is shown attached. The equation is:
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)
6.75 as a decimal is .0675
.0675 * 118 = 7.965
7.965 rounded to the nearest hundredth is 7.97 (since it's money)
118 + 7.97 = 125.97
So the final answer would be $125.97.
Hope I could help :)
