Keith_Richards [23]3 years ago
6 0

\boxed{x=3}

Step-by-step explanation:

The Standard Form of the equation of line is given by:

Ax+Bx=C \\ \\ For \ A, \ B, \ C\ Real \ Constant \\ and \ A>0

So:

6x+y=18 \\ \\ is \ written \ in \ standard \ form

The x-intercept can be found setting y=0:

6x+(0)=18 \\ \\ Isolating \ x: \\ \\ 6x=18 \\ \\ \boxed{x=3}

The number of violent crimes committed in a day possesses a distribution with a mean of 2.3 crimes per day and a standard deviat
marusya05 [52]

Answer:

B) approximately normal with mean 2.3 and standard deviation 2

Step-by-step explanation:

Given the following :

Mean crimes per day = 2.3

Standard deviation = 2

Number of samples = 100

Sampling distribution of the mean:

According to the central limit theorem:

Sample mean = population mean

2.3 = 2.3

The standard deviation of the sample (s) : ratio of the population standard deviation and square root of the sample size.

s = population standard deviation / √sample size

s = 2 / √100

s = 2 / 10

s = 0.2

The central limit theorem also posits that once ths sample size is large enough, the sampling of the sample mean will be approximately normal.

Hence, the distribution is approximately normal, with mean of 2.3 and standard deviation of 0.2

Your estimate that the length of a board is 24 feet. The actual length of the board is 22 feet. Find the percent error.
Tresset [83]

Answer:

9.09%

Step-by-step explanation:

You over estimated by 2 feet.  Find out how much 2 feet of 22 is by dividing 2 by 22...

2/22 = 0.090909090909

To convert a decimal to a percent, multiply the decimal by 100%

0.0909090909(100%) = 9.0909090909% or 9.09%

Demi has 221 songs on her phone. The songs take up 884 megabytes of storage . Each song takes up same amount of space . How many
sveticcg [70]

Answer:

540 megabytes

Step-by-step explanation:

We will first need to find out how much space a<em> singular song</em> will take up. We will do this by <em>the storage taken up (884) by the number of songs she has:</em>

884 / 221 = 4 mb taken up per song

Then we want to find out how many megabytes <em>135 of these songs take up</em>, so we will multiply the <em>mb taken up per song (4) by the number of songs we want to find (135)</em>:

4 x 135 = <em>540 megabytes</em>

<em />

<em>Edit: made a mistake in my original answer, apologies!</em>
