Answer:
Step-by-step explanation:
we know that
In the right triangle of the figure
The cosine of angle A is equal to divide the adjacent side to angle A by the hypotenuse
so
----> by CAH
Find the measure of the angle A
difference between standard deviation and mean deviation
Answer:
Standard deviation is basically used for the variability of data and frequently use to know the volatility of the stock. A mean is basically the average of a set of two or more numbers. Mean is basically the simple average of data
Hope this helps!!
The answer to your question is 2.5/4 negative i believe.
Answer:
Step-by-step explanation:
The problem here is that the question is not clear. In particular, what does "2)" mean?
Reflecting across the x axis is easy. Think of the x axis as a mirror. when you look in a mirror, your image is behind the mirror the same distance you are in front of the mirror. So, to reflect across the x axis, just multiply all the y values of the points by -1. For the reflection part
(-3,4) becomes (-3,-4)
(1,2) becomes (1,-2)
(-2,1) becomes (-2,-1)
Step 2 probably is a translation, but it is not clear what it is - so I cannot help you further.
If you get step 2 straight, the dilation by 3 is achieved by multiplying all the x and y values by 3.
