Answer:
0.321 is the probability that their mean printing speed of the sample is greater than 17.99 ppm.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 17.39 ppm
Standard Deviation, σ = 4.25 ppm
Sample size = 11
We are given that the distribution of printing speed is a bell shaped distribution that is a normal distribution.
Formula:
P(printing speed of the sample is greater than 17.99 ppm.)
P(x > 17.99)
Calculating the value from the standard normal table we have,
Thus, 0.321 is the probability that their mean printing speed of the sample is greater than 17.99 ppm.

<u>Answer:</u>
<u>ratios equivalent to 1/3=2/6,3/9</u>
<u></u>
<u>Step-by-step explanation:</u>
<u></u>
<u>Double number line is a diagram used when. quantities have different units.</u>
<u></u>
<u>It shows each of the quantities on its own number line with corresponding pairs of values lined up.The values of each number line are not the same unless there is a 1:1 ratio between them.</u>
<u></u>
<u>some ratios equivalent to 1:3 are;</u>
<u></u>
<u>2:6,3:9,4:12,5:15,6:18,7:21,etc</u>
Cot = cos/sin
So the vertical asymptotes would be wherever sin (2x) = 0 , which are :
x = 2pi
x = +- pi/2
x = pi
Hope this helps
