Answer:

\frac{b^2}{2}

Step-by-step explanation:

Answer:

(4, -2)

Step-by-step explanation:

Given a point R (-2,5), if the point R' is described by a translation of 6 units to the rights and 7 units down, then the coordinate of R' will be;

6 units to the rights is towards the positive x axis

7 units down is towards the negative y axis

R' = (-2+6, 5-7)

R' = (4, -2)

Hence the coordinate point of R' on the plane is (4, -2)

Answer:

  10/13 ≈ 76.9%

Step-by-step explanation:

P(A∪B) = P(A) +P(B) -P(A∩B)

P(plays basketball ∪ plays baseball)

   = P(plays basketball) +P(plays baseball) -P(plays both)

P(plays basketball ∪ plays baseball) = 16/26 +9/26 -5/26 = 20/26 = 10/13

P(plays basketball or baseball) = 10/13 ≈ 76.9%
