Josiah downloads 44 songs,including 16songs from his favorite band.

gogolik [260]

The number expressed as a decimal is 0.36

Step-by-step explanation:

First of all, we have to write the ratio between the number of songs from Josiah's favorite band and the total number of songs.

We have:

# of songs of his favorite band = 16

# of total songs = 44

Therefore, the fraction is:

$\frac{16}{44}$

Now we have to express this as a decimal. First of all, we simplify the fraction, by dividing each number by 4, and we get:

$\frac{16}{44} \frac{1/4}{1/4}=\frac{4}{11}$

Now in order to write this as a decimal, we just use the calculator and we divide 4 by 11, and we get:

$\frac{4}{11}=0.36363636....$

which is a periodic number, so we approximate to

$\frac{4}{11}=0.36$

Let x be the amount of time (in hours) the wait is to get a table at a restaurant. Suppose the cdf is represented by f(x)=⎧⎩⎨⎪⎪⎪

sattari [20]

Option a is correct. The calculated answer is 0.150

<h3>How to get the value using the cdf</h3>

In order to get P(0.5 ≤ X ≤ 1.5).

This can be rewritten as

p = 0.5

and P = 1.5

We have the equation as

$\frac{1}{16} x^{2}$

This would be written as

1.5²/16 - 0.5²/16

= 0.1406 - 0.015625

= 0.124975

This is approximately 0.1250

Which equation could represent a linear combination of the system?

Ghella [55]

The equation that could represent a linear combination of the system 2/3x + 5/2y = 15 and 4x + 15y = 12 is 0 = 26

<h3>What are linear equations?</h3>

Linear equations are equations that have constant average rates of change, slope or gradient

<h3>How to determine the linear combination to the system?</h3>

A system of linear equations is a collection of at least two linear equations.

In this case, the system of equations is given as

2/3x + 5/2y = 15

4x + 15y = 12

Multiply the first equation by 6, to eliminate the fractions.

6 * (2/3x + 5/2y = 15)

This gives

4x + 15y = 90

Subtract the equation 4x + 15y = 90 from 4x + 15y = 12

4x - 4x + 15y - 15y = 12 - 90

Evaluate the difference

0 + 0 = -78

Evaluate the sum

0 = -78

The above equation is the same equation as option (b) 0 = 26

This is so because they both represent that the system of equations have no solution

Hence, the equation that could represent a linear combination of the system is 0 = 26
