North component: y = 15.0m * sin55.0º = 12.3 m west component: x = 15.0m * cos55.0º + 7.00m = 15.6 m so his heading, measured from West, is Θ = arctan(y/x) = arctan0.787 = 38.2º N of West and measured from North is φ = arctan(x/y) = arctan(1.27) = 51.8º W of North
There are
female teachers, and
male teachers.
This means that, out of a total of 75 teachers, 45 are female, leading to a probability of
of selecting a female teacher.
If we restrict to those with more than 8 years service, there are 13 female teachers and 7 male teachers.
So, out of a total of 21 teachers, there are 13 female teachers, leading to a probability of
of selecting a female teacher.

Step-by-step explanation:
10 + 15 = 25
25 + 20 = 45
Answer:
$733.33
Step-by-step explanation:
The question is on finding the principal value
Formulae for simple interest
S.I= P×R/100×T where P is the invested amount of money, R is interest rate and T is time in years
Given that;
Simple interest=$77 , R=7% and T=1.5 years then
S.I= P×R/100×T...................substituting the values given
77=P×7/100 × 1.5
77=P×0.105
77/0.105 =P
$733.33=P
