Since angle 2 is 120 degrees, the corresponding angle is 6, so 6 will also be 120 degrees
6 and 8 should form 180 degrees
180 - 120 = 60
so angle 8 is 60 degrees
Answer:
a) Sample mean: 48.71
Sample median: 48.3
Sample variance: 5.41
Sample standard deviation: 2.37
Step-by-step explanation:
a) Sample mean:

Sample median: M=48.3
Note: I order the data increasingly and take the value N / 2 = 40. In this way there are 39 values above and 39 values below the median.
Sample variance:

Sample standard deviation

b)
Assuming that bob will use a circle with radius 1 unit,
then the area of the whole circle is A = pi R^2
A = 3.1416(1^2)
A = 3.1416
fraction of auto supplies = 120 / 3000 = 0.04
Area auto supplies = 3.1415(0.04) = 0.1257
formula for of a circular segment
A = 0.5r^2x
where x is the angle in radian
0.1257 = 0.5(1^2)x
x = 0.2513 rad
convert to degrees
x = 0.2513 rad ( 180 /pi)
x = 14.40 degrees
Answer:
The answer to your question is: ΔT = 112°F
Step-by-step explanation:
Data
highest temperature = 99°F
lowest temperature = -13 °F
Difference = ?
Process
ΔT = highest T - lowest T
Δ T = 99 - (-13)
ΔT = 99 + 13
ΔT = 112°F
