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:
29.74 degrees.
Step-by-step explanation:
Tan(theta) = opposite / adjcent.
opposite = 8
adjacent = 14
Tan(theta) = 8/14
Tan(theta) = 0.5714
theta = tan^-1(0.5714)
theta = 29.74 degrees
Greetings!Solve for x.

Multply both sides by
8 to get rid of the fraction.
