Answer:
Null hypothesis is rejected. Standard deviation is > 8 miles per hour
Step-by-step explanation:
σ [Population standard deviation] = 8 , s [sample standard deviation] = s
n [no of items] = 8
H0 [Null] : σ = 8 ; H1 [Alternate - Right Tail] : σ > 8
χ2 = (n - 1) . s^2 / σ^2
= 49 x (10.5)^2 / 82 = 5402.25 / 64
χ2 = 84.410
df [degree of freedom] = n -1 = 50 - 1 = 49
P value (χ^2 49 > 84.410) = 0.00125
p = 0.0013
p < α ie 0.05
So, H0 is rejected
Hence we state that standard deviation is > 8 miles per hpur
Answer:
angles one and two are supplementary angles and adjacent angles
Step-by-step explanation:
Definitions:
Supplementary angles: two angles that add to 180 deg
Adjacent angles: two angles that have a common side and a common vertex (corner point) and don't overlap
complementary angles: two angles that add up to 90 deg
vertical angles: two angles that are directly opposite from each other, formed by intersecting lines
Answer:
3 1/5 square units
Step-by-step explanation:
4 units * 4/5 shaded
4*4/5 = 16/5
Changing to a mixed number
5 goes into 16 3 times with 1 left over
3*5 = 15 16-15 = 1
3 1/5 square units
