The graph slanted from left to right.
4x + 2y = 8
-4x
2y=8-4x
divide the equation by 2 since you only need on y. -2x+8 =y
it's a negative x so the graph would be from upper left to lower right.
Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean), or expected value. A low standard deviation means that most of the numbers are close to the average. A high standard deviation means that the numbers are more spread out.
It is a measure of the average distance between the values of the data in the set and the mean. A low standard deviation indicates that the data points tend to be very close to the mean; a high standard deviation indicates that the data points are spread out over a large range of values.
So, good standard deviation is 5 = Very Good, 4 = Good, 3 = Average, 2 = Poor, 1 = Very Poor, The mean score is 2.8 and the standard deviation is 0.54.
Hope this helps :)
Answer:
Step-by-step explanation:
It is given that lies in the third quadrant.
In 3rd quadrant, sine and cosine both are negative.
Also given that:
We know that identity between sine and cosine as:
Here,
Therefore, the identity can be written as:
Putting the value of :
But, it is given that is in <em>3rd quadrant</em>. That means, value of cos will be <em>negative</em>.
Therefore, the correct answer is:
Answer:
3/4 is the probablity
Step-by-step explanation:
Answer:
B. 75.36 cubic cm
Step-by-step explanation:
We will use the formula V=π times r² times h
so, V= 3.14 times 2² times 6
so, V= 3.14 times 4 times 6
= 3.14 times 24
=75.36 cubic cm
