Answer:
-1113
Step-by-step explanation:
You apparently want the sum of the 14-term arithmetic sequence ...
-21, -30, -39, ..., -138
The average term is ...
(-21 -138)/2 = -79.5
so the sum of the 14 terms is ...
(14)(-79.5) = -1113
17
Σ (15 – 9n) = -1113
η = 4
- nth term
aₙ = 15 - 9n
a₄ = 15-9*4 = 15-36= -21
a₁₇ = 15 - 9(17) = -138
- Sum;
S = (a₁ + aₙ)*n/2
n = 14
a₁ = a₄= -21
aₙ = a₁₇ = -138
S = (-21 - 138)*14/2
S = -1113

James has $9
Priya has $10.80
Siobhan has $9.18
because 9*20% is 1.8 so add that to 9 to get 10.80 then times 10.80 by 15% to get 1.62 so you subtract 1.62 from 10.80 to get $9.18

Answer:
There is a 55.97% that a male can find a full time job in his chosen profession.
Step-by-step explanation:
We have these following probabilities:
A 60% probability that a college graduates cannot find a full time job in their chosen profession.
A 40% probability that a college graduates can find a full time job in their chosen profession.
57% of the college graduates who cannot find a job are female
43% of the college graduates who cannot find a job are male
18% of the college graduates who can find a job are female
82% of the college who can find a job are male.
Given a male college graduate, find the probability he can find a full time job in his chosen profession?
The total males are 43% of 60%(Those who cannot find a job) and 82% of 40%(Those who can find a job). So the percentage of males is
Those who are males and find a job in their chosen profession are 82% of 40%. So
There is a 55.97% that a male can find a full time job in his chosen profession.
