Answer: 3.3 per minute

Step-by-step explanation:

46.2 / 14.0 = 3.3

3.3 * 14.0 = 46.2

Hope this helps you!

46.2ft in 14 minutes is 46.2/14ft in 1 minute

46.2 ÷ 14 = 3.3

3.3ft per minute

What is the solution of 3x + 5 = 2x – 7?
Schach [20]

Answer:

the x-coordinates of the intersection point of the lines y = 3x + 5 and y = 2x – 7

Step-by-step explanation:

When you set two equations or functions equal to each other that is saying you want to know when the graphs intersect.  So the y and x intercept don't matter, unless you combined the terms like this.

3x + 5 = 2x – 7

x + 12 = 0 then that terms x intercept woudl be the x coordinate of the intersection of the other two terms.  But remember, this is onlyif you combines the two functions.  

Of your options you just want the ones dealing with the intersection point.  And of those two we are plugging in x, so we want the x coordinate.

The physical plant at the main campus of a large state university receives daily requests to replace fluorescent light bulbs. Th
ankoles [38]

We have been given that the distribution of the number of daily requests is bell-shaped and has a mean of 38 and a standard deviation of 6. We are asked to find the approximate percentage of lightbulb replacement requests numbering between 38 and 56.

First of all, we will find z-score corresponding to 38 and 56.

z=\frac{x-\mu}{\sigma}

z=\frac{38-38}{6}=\frac{0}{6}=0

Now we will find z-score corresponding to 56.

z=\frac{56-38}{6}=\frac{18}{6}=3

We know that according to Empirical rule approximately 68% data lies with-in standard deviation of mean, approximately 95% data lies within 2 standard deviation of mean and approximately 99.7% data lies within 3 standard deviation of mean that is -3\sigma\text{ to }3\sigma.

We can see that data point 38 is at mean as it's z-score is 0 and z-score of 56 is 3. This means that 56 is 3 standard deviation above mean.

We know that mean is at center of normal distribution curve. So to find percentage of data points 3 SD above mean, we will divide 99.7% by 2.

\frac{99.7\%}{2}=49.85\%

Therefore, approximately 49.85\% of lightbulb replacement requests numbering between 38 and 56.
