Answer:

ƒ(x) = (x - 2)^2 + 1

Step-by-step explanation:

To make f(x) be a translation of the graph of g(x) by (h, k), write it as ...

f(x) = g(x -h) +k

You want to translate g(x) = x^2 by (2, 1), 2 units right and 1 unit up, so the function f(x) is ...

f(x) = g(x -2) +1

you have been given an engine repair job that has a job time of 7 hours how many minutes should you allow for your job?

Soloha48 [4]

Answer:

$Job\ Time = 420\ minutes$

Step-by-step explanation:

Given

$Job\ Time = 7\ hours$

Required

Determine the job time in minutes

To do this, we simply convert the time to minutes.

$1\ hour = 60\ minutes$

$7\ hours = 7 * 60\ minutes$

So, we have:

$Job\ Time = 7 * 60\ minutes$

$Job\ Time = 420\ minutes$

<em>Hence, the job time in minutes is 420 minutes</em>

Write three different complex fractions that simplify to 1/4

andreyandreev [35.5K]

A complex fraction means that there must be a fraction in the numerator or denomenator or both

so

some are

$\frac{\frac{1}{8}}{\frac{1}{2}}$
$\frac{\frac{3}{8}}{\frac{3}{2}}$
$\frac{\frac{7}{8}}{\frac{7}{2}}$

Consider the following binomial experiment:

Sedbober [7]

Answer:

0.624

Step-by-step explanation:

Given that:

Number of copiers with the company = 4

It is a binomial experiment.

Probability that on a given day, one copier will break down = $\frac{23}{50}$

$p = \frac{23}{50}$ = 0.46

$q = 1-p = 1-\frac{23}{50}= \frac{27}{50}$ = 0.54

<em>Formula for Binomial probability: </em>

$P(x=r) = _{n}C_{r}p^rq^{n-r}$

We have to find $P(x >= 2)$

$P(x >= 2) = P(X=2)+P(X=3)+P(X=4)$

$P(x=2) = _{4}C_{2}0.46^2\times 0.54^{2} = 0.37\\P(x=3) = _{4}C_{3}0.46^3\times 0.54 = 0.21\\P(x=4) = _{4}C_{4}0.46^4\times 0.54^{0} = 0.044$

$P(x >= 2) = 0.37 + 0.21 + 0.044 = \bold{0.624}$
