Answer:

15.

Step-by-step explanation:

The given functions are

$f(x)=3x$

$f[g(1)]=f[(1)+4]$

$h(x)=x^2-1$

We need to find the value of f[g(1)].

$f[g(1)]=f[(1)+4]$ $[\because f[g(1)]=f[(1)+4]]$

$f[g(1)]=f[5]$

$f[g(1)]=3(5)$ $[\because f(x)=3x]$

$f[g(1)]=15$

Therefore, the value of f[g(1)] is 15.

What is log Subscript 15 Baseline 2 cubed rewritten using the power property?

nalin [4]

Answer:

The equivalent expression

Step-by-step explanation:

Assuming your expression is $\log_{15}2^3$ , then we can use the power property of logarithm , which is $\log_ab^n=n\log_ab$ .

If we let a=15, b=2, and n=3

Then using the power property of logarithm will give us:

$\log_{15}2^3=3\log_{15}2$

Using the power property of logarithm, the equivalent expression is $3\log_{15}2$

A company administers an "aptitude test for managers" to aid in selecting new management trainees. Prior experience suggests tha

RoseWind [281]

Answer:

0.94

Step-by-step explanation:

The question after this basically is:

<em>"If the applicant passes the "aptitude test for managers", what is the probability that the applicant will succeed in the management position?"</em>

<em />

So,

P(successful if hired) = 60% = 0.6 [let it be P(x)]

P(success at passing the test) = 85% = 0.85 [let it be P(y)]

P(successful and pass the test) = P(x) + P(y) -[P(x)*P(y)]

So,

P(successful and pass the test) = 0.6 + 0.85 - (0.6*0.85) = 0.94 (94%)
