1. the common formula for this graph is y=A*cos(Bx), where A - the amplitude, B - the frequency of the given function.
2. The max. and min. vertical values are 4 and (-4), it means that the amplitude is 4 (A=-4*),
for the function y=cosx the period is 2π, it means for the given function the period is π/2, it is for its frequency 2π/(π/2)=B=4.
* if to see to the suggested graph, the max. of cos4x are in points π/4+πn, and the min. are in π*n/2, it means that it need to add '-' in the equation of the function.
3. answer: y=-4cos4x.
Answer:
Yes
Step-by-step explanation:
It is a direct variation of the X,Y,Z family. This is due to the 3rd party uneven number.
- The distribution is skewed left.
- The median is an accurate measure of center.
- The interquartile range is an accurate measure of spread.
<h3>How to find the Distribution of data?</h3>
Probability plots might be the best way to determine whether your data follow a particular distribution. If your data follow the straight line on the graph, the distribution fits your data. This process is simple to do visually. Informally, this process is called the “fat pencil” test.
For skewed distributions, it is quite common to have one tail of the distribution considerably longer or drawn out relative to the other tail.
As, it is known that, when the distribution of data is left-skewed, the mean is less than median.
- In any research of distribution, the distribution is described by its shape. If there are more higher values than lower values, the distribution is skewed left.
- The distribution can be described by its center. If the distribution is skewed left or right, the median is an accurate measure of center.
- The distribution can be described by its spread. If the data set does not have an outlier, the interquartile range is an accurate measure of spread.

#SPJ1
Answer:
7.5 years.
Step-by-step explanation:
Use A = 1400(1+0.02)^7.5
The 1400 is the starting money. The 1 is a constant. The 0.02 is the 2% in decimal form. And the 7.5 is years. I found that by just continually increasing it until it hit 1624.
Hope this helps
