Answer:
C. All of the data values are identical.
Step-by-step explanation:
If the standard deviation for a set of data is 0, then all of the data values are identical.
When a standard deviation is 0, then the variance is also 0 and the mean of the deviation that is squared is also 0, thereby making all the values identical to the mean, that is 0.
Answer:
36%
Step-by-step explanation:
line up $ and % data like this:
$2.79 represents 100%
$3.79 represents X%
cross multiply
X*2.79 = 3.79*100
divide both sides by 2.79
X= 3.79*100 / 2.79 ≈ 136%
so it increased 36%
Answer:
Step-by-step explanation:
Add 20 to both sides:
Multiply 8 on both sides:
Divide by 13 on both sides:
Sin D= opp./hyp. = 35/37
cos D= adj./hyp. = 12/37
tan D= opp./ adj. = 35/12
