Answer:
t = 0.7
Step-by-step explanation:
s = k/t where 'k' is the constant of variation
given: 0.5 = k/7 so k = 3.5
5 = 3.5/t
5t = 3.5
t = 0.7
Pupils that chose Band: 60%
Pupils that chose Chorus: 40%
Boys in band: 70%
Boys in chorus: 30%
Probability of choosing boy = Probability of boy in band + Probability of boy in chorus
P = 0.6 x 0.7 + 0.4 x 0.3
P = 0.54
The answer is D.
we have

the vertex of the function g(x) is the point 
the vertex of the function f(x) is the point 
so
the rule of the translation of g(x) to f(x) is
(x,y)------> (x,y-4)
that means
the translation is
units down
therefore
the equation of the function f(x) is

therefore
<u>the answer is</u>
