A measure of the variation around the estimate of the mean.
The standard deviation is a statistic that lets you know how tightly all the subjects are clustered around the mean in a set of data. A single standard deviation away from the mean in either of the directions accounts for somewhere around 68 % of data. If two standard deviations are away from the mean, it accounts for around 95% of data. If three standard deviations are away it accounts for 99% of the data.
1) The total range of variation in the dataset is called RANGE.
3) A measure of the variation around the estimate of the mean is SEM (STANDARD ERROR OF THE MEAN).
4) The most common value observed (highest frequency) is MODE.
Answer:
X=1/3-4
Step-by-step explanation:
the answer is x equals one over three minus 4
Answer:
x = 3.7
Step-by-step explanation:
Reference angle = 24°
Hypotenuse = 4
Side adjacent to reference angle = x
We would apply the trigonometric ratio, CAH, which is:
Cos 24 = adj/hyp
Cos 24 = x/4
4 × Cos 24 = x
x = 3.65418183 ≈ 3.7 (to nearest tenth)
Answer:
a=6
Step-by-step explanation:
write the equation as y=mx+b
y=-5/3x+b
solve for b
1=-5/3*-3+b
1-5=b
b=-4
Plug in -14 and solve for x
-14=-5/3x-4
-10=-5/3x
30/5=x
x=6 (x is basically a because a is the x coordinate)
1. a=b+cx
2. a-b=cx subtract b
3. a-b/x=c divide by x to get c by itself
Answer: a-b/x=c
