If f ( x ) = 2x + 2 and g ( 1 ) = 3x – 1, find (f/g) (2)

schepotkina [342]

Answer:

6/5 or 1.2

Step-by-step explanation:

Given functions:

f (x) = 2x + 2
g (x) = 3x – 1

To find:

(f/g) (2)

Solution

(f/g)(x) = f(x)/g(x) = (2x + 2) / (3x - 1)
(f/g)(2) = (2*2 + 2) / (3*2 - 1) = 6/5 = 1.2

Isabel wrote this mystery problem. The quotient is multiple of 6. The dividend is multiple of 9. The divisor is a factor of 12.

Marina86 [1]

Answer:

Consider the expression $q=\frac{a}{b}$ . q is called the quotient, a is is the dividend and b is the divisor.

Since q is a multiple of 6, then q has the form $q=6k$ for some integer k.

Since a is a multiple of 9, then a has the form $a=9s$ for some integer s.

Since b is a factor of 12, then if 12 can be expressed of the form $12=c*b$ , for c an integer. Then b has the form $b=\frac{12}{m}$

Replacing the preview expression in the initial expression we obtain:

$6k=\frac{9s}{\frac{12}{m}}=\frac{9sm}{12}\\6*12k=9sm\\72k=9sm\\72k-9sm=0$

Then $72k-9sm=0,\; for \; k,s,m\in \mathbb{Z}$ is a equation to Isabel's problem.

Suppose that a random sample of size 64 is to be selected from a population with mean 40 and standard deviation 5. (a) what are

Vika [28.1K]

The sample mean is equal to the population mean.
$\bar{X}=\mu=40$
The standard deviation of X-bar (the standard error) is:
$S.E.=\frac{\sigma}{ \sqrt{n} }=\frac{5}{\sqrt{64}}=0.625$
