Answer:
Pr(tablet given smartphone) = 18%
Step-by-step explanation:
Let:
probability that the student has a smartphone = Pr(smart phone)
Pr(smart phone) =0.71
the probability that the student has a tablet = Pr(tablet)
Pr(tablet) = 0.28
the probability the student has both = Pr(both)
Pr(both) = 0.13
the probability a student has a tablet given they have a smartphone = Pr(tablet given smartphone)
Pr(tablet given smartphone) = Pr(tablet & smartphone)/Pr(smart phone)
Pr(tablet given smartphone) = 0.13/0.71
Pr(tablet given smartphone) = 0.183 = 18.3%
Pr(tablet given smartphone) = 18%
Answer:
Solve for n:
28 = n
Hint: | Reverse the equality in 28 = n in order to isolate n to the left hand side.
28 = n is equivalent to n = 28:
Answer: n = 28
Step-by-step explanation:
Answer:
arithmetic
Step-by-step explanation:
It is arithmetic because the terms go up by 15 . That is the common difference is 15.
Step-by-step explanation:
x/-4=-5
x=20.............
The angles of a triangle always equal to 180 degrees.
Knowing this, you can solve this by this equation
Angle A + Angle B + Angle C = 180
43 + 85 + Angle C = 180
Angle C = 180 - 43 - 85
Angle C = 52
