Answer:
Option D) The number of standard deviations a measurement is from the mean
Step-by-step explanation:
Standard Score:
- Standard score is also known as the z-score, z-value, normal scores or the standardized score.
- It tells us about the values of standard deviations by which the value of data point is above or below the mean value.
- The standard score for a data point may be negative or positive.
- It is obtained by subtracting the population mean from the data point and then dividing it by the population standard deviation.
- It is known as standardization or normalization.
Thus, standard score can be defined as:
Option D) The number of standard deviations a measurement is from the mean
24. The answer is D ,because trapezoids don't have equal sides, parallelograms don't have 5 sides, and they don't all have the same angles. Each side is the same length
Y=1/2x-2
To find the point where the two lines intersect they are set equal to each other so that x can be found:
2x-5=-x+1
2x+x=1+5
3x=6
x=2
If x is known, x can be plugged into one of the two equations to find y.
y=-x+1=-2+1=-1
This means the point where they intersect is (2,-1).
We also know that the slope has to be 1/2 because the slope has to match the slope of the line it is parallel to.
Putting this into point slope form, we get:
(y-(-1))=1/2(x-2)
Which can be simplified into slope intercept form:
y+1=1/2x-1
y=1/2x-1-1
y=1/2x-2
Answer:
16%
Step-by-step explanation:
$85 - $71.40 = $13.60
= 16%
