Answer:

Step-by-step explanation:
First, begin by multiplying
by its reciprocal.
To do this, flip the fraction upside-down.
The resulting equation looks like this: 
Cancel out the two 27's and you are left with
, which you can simplify to q.
Next, multiply -3 by
. Remember, what you do on one side, you must do on the other.
Your equation should look like this:

The final answer is
.
Have a nice day!
Answer: acute
Step-by-step explanation: it is less than 90 degrees so it is less the right angle
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.
