What is the measure of the angle between a perpendicular bisector and the segment it is bisecting? A. 180° B. 90° C. 45° D. 0°

gregori [183]

If something is perpendicular to something else, it intersects it at 90 degrees. So, it there is a bisector perpendicularly bisecting a segment, it means they are crossing at a 90 degree angle. Your answer should be B.

What is the P(1,6,4) on 3 rolls of a dice? show how you got the answer!

julia-pushkina [17]

Answer:

Step-by-step explanation:

Given the sample space of a die S=(1,2,3,4,5,6)

and the sample size=6

the probability of obtaining the number 1 Pr(1)= 1/6= 1/6

the probability of obtaining the number 6 Pr(1)= 6/6= 1

the probability of obtaining the number 4 Pr(1)= 4/6= 2/3

Hence the probability of P(1,6,4) = $\frac{1}{6} *1 *\frac{2}{3} =\frac{2}{18} = \frac{1}{9} \\$

Simplify the rational expression <br> x^4 y^2/xy^7.

sammy [17]

Answer: $x^3y^9$

Step-by-step explanation:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): Dot was discarded near "7.".

Simplify $\frac{y^2}{x}$

<u>The equation at the end of step 1:</u>

$((x^4)*\frac{y^2}{x} )*y^7$

<u>Multiplying exponential expressions:</u>

2.1 $y^2$ multiplied by $y^7$ $=y^(2+7)=y^9$

Final result is $x^3y^9$
