Answer:
The bolts with diameter less than 5.57 millimeters and with diameter greater than 5.85 millimeters should be rejected.
Step-by-step explanation:
We have been given that the diameters of bolts produced in a machine shop are normally distributed with a mean of 5.71 millimeters and a standard deviation of 0.08 millimeters.
Let us find the sample score that corresponds to z-score of bottom 4%.
From normal distribution table we got z-score corresponding to bottom 4% is -1.75 and z-score corresponding to top 4% or data above 96% is 1.75.
Upon substituting these values in z-score formula we will get our sample scores (x) as:


Therefore, the bolts with diameters less than 5.57 millimeters should be rejected.
Now let us find sample score corresponding to z-score of 1.75 as upper limit.


Therefore, the bolts with diameters greater than 5.85 millimeters should be rejected.

Answer:
14, -7, -2
Step-by-step explanation:
<u>The coefficient is the number that multiplies the variable, so list the numbers that fall under that definition:</u>

B i think the answer is for #5
Answer:
- 75 - 32y
Step-by-step explanation:
2y-3[3-4(y-5)+2(1-3y)]
= 2y - 3(3 - 4y + 20 + 2 - 6y)
= 2y - 3(25 - 10y)
= 2y - 75 - 30y
= - 75 - 32y
