Which statement is true about whether cap A and cap b are independent events?

A
cap A and cap b are not independent events because cap p times open paren cap A divides cap b close paren is not equal to cap p times cap A .
B
cap A and cap b are independent events because cap p times open paren cap A divides cap b close paren is equal to cap p times cap A .
C
cap A and cap b are not independent events because cap p times open paren cap A divides cap b close paren is not equal to cap p times cap b .
D
cap A and cap b are independent events because cap p times open paren cap A divides cap b close paren is equal to cap p times cap b .

Which best explains whether or not all isosceles triangles are similar?

A
All isosceles triangles are similar. Two angles within each triangle are always congruent.
B
All isosceles triangles are not similar. Given only the vertex angle of an isosceles triangle, there is not enough information to determine the measures of the base angles. Therefore, it is not possible to determine if the base angles of one isosceles triangle are congruent to the base angles of another.
C
All isosceles triangles are not similar. The pair of congruent angles within one triangle is not necessarily congruent to the pair of congruent angles within the other triangle.
D
All isosceles triangles are similar. The triangle sum theorem states that the sum of the angles in a triangle is 180 degrees . Therefore, the third angle can always be determined.

Two chords intersect at a point inside a circle that is not the center of the circle. Which statement must be true?

A
The measures of each pair of opposite arcs sum to 180 degrees .
B
Each angle measure is equal to the measure of the arc it intercepts.
C
Each arc measure is equal to one-half the sum of the vertical angles that intercept the arc.
D
The sum of the measures of each pair of vertical angles is equal to the sum of the measures of the intercepted arcs.

Point cap p partitions the directed segment from cap A to cap b into a ratio of 1 to 3 ratio. cap q partitions the directed segment from cap b to cap A into a ratio of 1 to 3 ratio. Are cap p and cap q the same point? Why or why not?

A
Yes, they both partition the segment into a ratio of 1 to 3 ratio.
B
No, cap q is closer to cap A and cap p is closer to cap b .
C
Yes, they are both 1 fourth the distance from one endpoint to the other.
D
No, cap p is 1 fourth the distance from cap A to cap b , and cap q is 1 fourth the distance from cap b to cap A .

Juanita has a storage closet at her shop with extra bottles of lotion and shower gel. Some are scented and some are unscented. If she reaches into the closet and grabs a bottle without looking, she has a 42 percent chance of grabbing a bottle of shower gel. For the events "shower gel” and "scented” to be independent, what must be shown to be true?

A
cap p times scented is equal to 42 percent
B
cap p times open paren scented divides shower gel close paren is equal to 42 percent
C
cap p times lotion is equal to 42 percent
D
cap p times open paren shower gel divides scented close paren is equal to 42 percent
