Variance = square of standard deviation
Variance = (2.5)^2 = 6.25 = 6.3 to the nearest tenth.
Answer:
Step One
Calculate the area of both the skating area and the spectator area.
Area = L * W
L = 4x
W = 4x
Area = 4x * 4x
Area = 16x^2
Step Two.
Find the radius of the semicircle. R = radius
From the diagram
R = The full length - the length given in the red shaded area.
R = 4x - 2x
R = 2x
Step Three
Find the area of the semicircle.
Area of a full circle = pi R^2
Area of a 1/2 circle =
Area of a 1/2 circle =
Area of a 1/2 circle =
Notice that the 2 in the denominator cancels in part with the 4 in the numerator.
Step Four
Find the area of the shaded area
Area of the shaded Area = Whole Area - Area of the Semi Circle.
Area of the shaded Area = 16x² -
The answer is the upper right corner choice I think
Answer:
• for y-intercept, x is zero
• therefore:
First, we should find out what the circumference of one can is and then multiply it by two, because they ask us about two cans.
The formula for calculating the circumference is:
C = 2πr
Good news - we have r! r equals 8.3 cm.
So the circumference of one can, hence length of one piece of paper, equals 2π * 8.3 = 16.6π. Length of two pieces of paper is the result of this multiplication: 2 * 16.6π = 33.2π
Answer:
i honestly am not sure but think it is distributive property.
