It took them 4 days to install 480 chairs which means if they were working at a constant rate they got 120 chairs installed daily. with 360 chairs left that means in 3 days they will finish. so overall, it took the workers 7 days to finish, or a week.
The confidence interval is

We first find p, our sample proportion. 118/200 = 0.59.
Next we find the z-score associated with this level of confidence:
Convert 98% to a decimal: 98% = 98/100 = 0.98
Subtract from 1: 1-0.98 = 0.02
Divide by 2: 0.02/2 = 0.01
Subtract from 1: 1-0.01 = 0.99
Using a z-table (http://www.z-table.com) we see that this value is associated with a z-score of 2.33.
The margin of error (ME) is given by

This gives us the confidence interval
Answer:
<u>Point-slope form</u>: y - 12 = 10 (x - 5)
<u>Slope-Intercept form</u>: y= 10x - 38
Step-by-step explanation:
im not fully sure which equation ur looking for but i think thats right lol. hopefully this helps ! :)
Answer:
m = 21
n= 25
Step-by-step explanation:
