Answer:
C: 4 hours
Step-by-step explanation:
Mean = Σxn/n
Σx/n = ((2 × 4) + (3 × 5) + (4 × 6) + (5 × 3) + (6 × 3) + (7 × 0) + (8 × 1))/(4 + 5 + 6 + 3 + 3 + 0 + 1)
Σx/n = 88/22
Σx/n = 4 hours
5) 0.42
6) 0.33
8) 0.25
9) 0.56
The slope would be -x+6 & m=-1
Answer:
39.6 cm²
Step-by-step explanation:
The formula for the area of a trapezoid is given as:
Area of a Trapezoid = 1/2(a + b) h
Where, from the question:
a = 8.9 cm
b = 5.5 cm
h = 5.5cm
Hence,
1/2 (8.9cm + 5.5cm) × 5.5cm
= 1/2 × 14.4 cm × 5.5 cm
= 39.6 cm²
Area of the Trapezoid = 39.6 cm²
Well u have a circle and you cut it into 12 parts.
that means that each sector will have 3 angles.
so you would take the first sector which is 90 degrees and divide it by 3.
you would get each angle being at 30 degrees.
>>so 1/12 of a circle would be >> 30 degrees
hope this helps
