Answer:
the greater the precision the smaller the standard deviation
there is no relationship between standard deviation and accuracy
Step-by-step explanation:
The standard deviation of a set measures how close the measures of this set are, that is, how precise they are.
The lesser the standard deviation is, the higher the precision is.
So the correct answer is:
the greater the precision the smaller the standard deviation
Accuracy is how close a measurement comes from the correct value. There is no relation between standard deviation and accuracy.
So:
there is no relationship between standard deviation and accuracy
Answer:
∠5 = 60°
∠6 = 30°
∠7 = 120°
Step-by-step explanation:
Since the polygon is regular, you know that the central angle (7) is 1/3 of the circle, or 120°. The angle 5 is half that measure, so is 60°, and the angle 6 is the complement of angle 5, so is 30°. (Angle 6 is also half the inscribed angle at each vertex, said inscribed angle being 120°/2 = 60°.)
∠5 = 60°
∠6 = 30°
∠7 = 120°
The answer is
A. 3x - y= -7
Answer:
The slope is 13.
The x intercept is 
.
The y intercept is 
.
Step-by-step explanation:
1. Finding the slope.
This is a linear equation, because <u>it's graph forms a line</u>. In a linear equation, the slope is always the value that multiplies x. In this case, x is being multiplied by 13, therefore, <u>the slope is 13</u>.
2. Finding the x intercept.
The x intercept is found when the value of y is 0. Let's replace the value of y for 0 in the equation and solve the x:
<u>The x intercept is </u><u>.</u>
3. Finding the y intercept.
The y intercept is found when the value of x is 0. Let's replace the value of x for 0 in the equation and solve the y:
<u>The y intercept is </u><u>.</u>
It’s 3!! I checked on a calculator :)
