Answer:
Mr Blake's science class
Step-by-step explanation:
The standard deviation is a measure of variation.
It tells us how far each of the data set in the distribution are far from the mean of the distribution.
The average score of students in Mr. Blake's science class was 73 with a standard deviation of 11, while the average score of students in Mrs. Arnold's class was 75 with a standard deviation of 10.
Since 11>10, Mr Blake's science class is more variable than Mrs. Arnold's class.
Answer:
31/30 or 1 1/30
Step-by-step explanation:
1/3+1/5+1/2
Y=x/5
divide 5 on both sides, this is as far as you can simplify the equation with the information given
Formula for finding circumference of a circle is 2πr.
Step-by-step explanation:
- The given question says what is the circumference of a circle that is 9cm.
- As radius is required for finding circumference of a circle, the formula is 2πr.
- Therefore taking the formula and substituting radius (r)= 9 cm. We get 2πr as 2×π×9 = 18π cm OR
- If we substitute the value of π as 3.14 we will get⇒ 2×3.14×9= 56.52 cm.
- So the circumference of the given circle would be 18π or 56.52 cms.
Answer:
See screenshot for graph and points - This is <em>not</em> a function because it fails the vertical line test.
Step-by-step explanation:
The vertical line test means that if you can draw a vertical line anywhere on the graph and it hits more than one part of the graph, then it isn't a function.
