Answer:
Step-by-step explanation:
Hi,
We know that
P(A or B)=P(A)+P(B)-P(A and B)
so P(B)= P(A or B) - P(A) + P(A and B)
so
P(B) = 0.5 - 0.4 + 0.2 = 0.3
thanks
Answer:
Distance around the pool = 162.8 feet
Area of the pool = 957 square feet
Step-by-step explanation:
Distance around the swimming pool = Perimeter of the pool
Perimeter of the pool which is a composite figure will be,
= Circumference of the semicircle + Sum of three sides of the pool
= πr + 2×(length of the pool) + width of the pool
= 3.14×(10) + 2×40 + 20
= 62.8 + 80 + 20
= 162.8 ft
Area of the pool = Area of the semicircle + Area of the rectangular pool
=
=
= 157 + 800
= 957 square feet
Answer:
x ≈ - 1.28
Step-by-step explanation:
Using the rule of logarithms
x = n ⇔ x =
Given
ln(x + 4) = 1 , then
x + 4 = ( subtract 4 from both sides )
x = - 4 = - 1.28 ( to the nearest hundredth )
