The population of Weston is 4320. The town’s records show that 45 percent of the population are males, and 2 3 23 of these males

lbvjy [14]

Answer:

In Weston 1,296 males are married

Step-by-step explanation:

step 1

Find out the number of males

Multiply the total population by 45%

$45\%=45/100=0.45$

$4,320(0.45)=1,944\ males$

step 2

Find out the number of males that are married

Multiply the number of males by 2/3

$\frac{2}{3}(1,944)=1,296\ males\ married$

therefore

In Weston 1,296 males are married

F(x) = x(x - 1) g(x) = 3x find (f*g)(6)

svetlana [45]

Step-by-step explanation:

Given functions:

f(x) = x(x - 1)
g(x) = 3x

Find (f*g)(6):

(f*g)(6) = f(6)*g(6) = 6(6 - 1)*3(6) = 30*18 = 540

In case it is a composite function (f · g)(6) the answer is different:

(f · g)(6) = f(g(6)) = f(3*6) = f(18) = 18*(18 - 1) = 306
