Write the following inequality in slope-intercept form. −6x + 2y ≤ 42

zubka84 [21]

Add the 6x to both sides. Then divide both sides by 2 to get y by itself.

y <= 6x + 42

Note: if it were a -2y, you’d have to flip the inequality sign when dividing by that negative 2.

Hospital records show that a certain surgical procedure takes on an average 111.6 minutes with a standard deviation of 2.8 minut

Arisa [49]

Answer:

At least 37.74% of the procedures takes between 97.6 and 125.6 minutes

Step-by-step explanation:

The percentage is the area of the standard normal distribution curve between the values 97.6 and 125.6

The standard normal variate of the given data is found as

$Z=\frac{X-\overline{X}}{\sigma }$

Thus for the given values Z is calculated as under

$Z_1=\frac{97.6-111.6}{2.8}=-5$

Similarly for the other value we have

$Z_2=\frac{125.6-111.6}{2.8}=5$

Thus the area between the calculated values can be found from standard normal distribution table to be 37.74%
