Answer:
E. 10 and 10
Step-by-step explanation:
Standard Deviation is the square root of sum of square of the distance of observation from the mean.
where,
is mean of the distribution.
Here, since standard deviation is the ratio of the distance from the mean and sample size. So for decreasing the standard deviation we should keep numerator constant and increasing the denominator.
This can be only possible in option (E).
Hence, only Option (E) is correct.
Answer:
y = 26
Step-by-step explanation:
The angles of a linear pair total 180°.
__
(2y +1)° +(5y -3)° = 180° . . . . the sum of the angles is 180°
7y -2 = 180 . . . . . . divide by °, collect terms
7y = 182 . . . . . . . . add 2
y = 26 . . . . . . . . . divide by 7
_____
<em>Additional comment</em>
The angle measures are (2(26) +1)° = 53°, and (5(26) -3)° = 127°. These total 180°, as they should.
