the standard form of a quadratic is : y = ax² + bx + c : (a ≠ 0 )
note that (x - 0 )² = x²
distributing by - 0.3 gives
y= - 0.3x² + 3 ← in standard form
with a = - 0.3, b = 0 and c = 3
Answer:
Solution given:
f(x)=x²
g(x)=x+5
h(x)=4x-6
now
23:
(fog)(x)=f(g(x))=f(x+5)=(x+5)²=x²+10x+25
24:
(gof)(x)=g(f(x))=g(x²)=x²+5
25:
(foh)(x)=f(h(x))=f(4x-6)=(4x-6)²=16x²-48x+36
26:
(hof)(x)=h(f(x))=h(x²)=4x²-6
27;
(goh)(x)=g(h(x))=g(4x-6)=4x-6+5=4x-1
28:
(hog)(x)=h(g(x))=h(x+5)=4(x+5)-6=4x+20-6=4x-14

b. How many subjects were included in the study?
The total number of subjects in the study was___.
c. How many subjects did not use marijuana?
A total of ___subjects did not use marijuana.
Answer:
(a)0.615
(b)304
(c)183
Step-by-step explanation:
Among 147 subjects with positive test results, there are 30 false positive (actually negative) results;
Among 157 negative results, there are 4 false-negative (actual positive) results.
The table below summarises the given data.
(a)The probability that a randomly selected subject tested negative or did not use marijuana
P(negative or did not use marijuana)
=P(negative)+P(did not use marijuana)-P(both)
(b)There were a total of 304 subjects in the study.
(c)A total of 183 subjects did not use marijuana.
