Answer:

Step-by-step explanation:

supposing this is with replacement, you find the probability of choosing rock songs which is rock/all the songs aka 3/(3+3+2)=3/8

now that we know the probability of choosing one rock song, since its twice we multiply by itself

3/8 x 3/8= 9/64

you can't simplify this fraction so the answer is 9/64

you welcome

Slav-nsk [51]

ANSWER

$f(x) = 4( {3}^{x} ) + 2$

EXPLANATION

The exponential function in the form

$f(x) = a( {b}^{x} ) + c$

has a horizontal asymptote of

$y = c$

The given exponential function is:

$f(x) = 4( {3}^{x} ) + 2$

The horizontal asymptote is therefore

$y = 2$

Geoff and Max are college roommates. Geoff can clean their apartment in 2.5 hours and Max can clean their apartment in 3.25 hour

Anestetic [448]

Answer: 1.41 hours

Step-by-step explanation:

Geoff: 2.5 hours = 1 job

Max: 3.25 hours = 1 job

Together: $\frac{x}{2.5} + \frac{x}{3.25} = 1 job$

⇒ $(3.25)(2.5)\frac{x}{2.5} + (3.25)(2.5)\frac{x}{3.25} = (3.25)(2.5)1$

⇒ 3.25x + 2.5x = 8.125

⇒ 5.75x = 8.125

÷5.75 ÷5.75

x = 1.413

James answered 14 items correctly on a 16-item quiz. what percent did he answer correctly?

Troyanec [42]

So,

I like to simplify a fraction first. This is what I do when I'm in a store trying to find the unit price.

$\frac{14}{16}$

Factor.
$\frac{2*7}{2*2*2*2}$

Cross out ones.
$\frac{7}{2*2*2}$

Multiply it out.
$\frac{7}{8}$

In my head, I remember that one-eighth is equal to 0.125.

So seven-eighths is equal to 0.125 times 7.
0.125 * 7 = 0.875

Convert to percent form.
0.875 --> 87.5%

James answered 87.5% of his quiz correctly.

I actually have the decimal equivalents for eighths in my head when I'm shopping. So once I get seven-eighths, I immediately know how much that is. I can also subtract 0.125 from 1.000 to get seven-eighths.
