Option (2)
Step-by-step explanation:
Measure of angle formed by two tangents from a point outside the circleis half the difference of the measures of the intercepted arcs.
From the figure attached,
m∠C =
=
=
=
= 180 - 150
= 30°
Therefore, measure of angle C will be 30°.

Step-by-step explanation:
Range Rule of Thumb
- The range Rule of thumb states that the range is four times the standard deviation.
- The standard deviation is a measure of dispersion.
- Thus, the correct answer is
Answer:
% area of the shaded region = 33%
Step-by-step explanation:
Radius of the middle circle = 7 cm
Radius of the inner circle = 4 cm
Area of the middle circle = πr²
= π(7)²
= 49π
Area of the inner circle = π(4)²
= 16π
Area of the shaded region= 49π - 16π
= 33π
Area of the outermost circle = π(10)²
= 100π
% area of the shaded region =
=
= 33%
Therefore, area of the shaded region is 33% of the complete logo.
