Answer:
2. Stepford is the least consistent in daily temperatures because its standard deviation is the highest.
Step-by-step explanation:
Standard deviation is the average amount that each data point is from the mean. The lower the standard deviation is, the closer each data point is to the mean; this means it is more consistent if it has a low standard deviation.
Stepford has the highest standard deviation; this means it is the most variable, or least consistent.

Short Answer: 6 + (44 + 28)
Long Answer:
Change the parentheses to include 28 and not include 6. According the the property, changing the parentheses this way does not affect the sum. In other words, changing the order of addition does not change your answer.
Answer: 140
Step-by-step explanation:
angle 2 is 140 becuase 180 minus 40 = 140
angle 4 is 140
Answer:
Step-by-step explanation:
1)
O = center of circle (origin)
we know that the angle at the center of the circle ∠ ROS will be
180= 2(31) + ∠x
180-62 = ∠x
118° = ∠x
The supplemental angle to the 118° will be 62°
62° is the interior angle to arc QR , so
arc QR is also 62°
3)
b/c the intercepted arc YZ = 2* 68=136
then 136+125+? = 360
? = 99°
arc ZX = 99°
5)
O= center point
we are given the two arcs 120 and 70 for both of these we know that the
interior angles will be the same. ∠JOX has a central angle of 120 , then
b/c triangle JOX is an isosceles, we know that the two angles J and X of
the triangle JOX will be 1/2 of 60 , or 30 each
also for
also ∠XOY has an interior angle of 70 so the two angle at X and Y will be 1/2 of 110 , or 55°
now add 55+30 to find X for box XYZJ
85° = ∠X
