Answer:
0.14
Step-by-step explanation:
1/7 = 0.1428571429.......
round to two decimal places so se look at the 4 which is the second decimal place, and then we see that the number to the right of it is less than 5 and therefore we round down to 4 and not 5.
:) hope this helps, please mark as brainliest!
Lucy packs plates faster she packs 5 plates every minute. Mike packs 4 plates every minute because 3/4 of an hour is 45 minutes, then you divide 180 by 45 and the answer is 4 per minute.
Franco would have to pack 90 plates every 20 minutes (1/3 of an hour) for his rate to be between Lucy's and Mike's. Lucy's rate is at 100 plates per 20 minutes because she can pack 5 plates every minute. Mike's it's at 80 plates per 20 minutes because he can pack 4 plates per minute. So that means that For Franco to be in the middle he has to pack 90 Plates every 20 minutes.
Hope this helps!!!
Answer:
the answer is x = 7
Step-by-step explanation:
1) replace the x with 7

4) 28 - 5 = 23
they're both equal as perpendicular angles should be!
Answer:
A) 2.6 mm Hg
Step-by-step explanation:
Margin of error = critical value × standard error
ME = CV × SE
n > 30, so we can approximate CV with a normal distribution. At P = 94%, CV = 1.88.
SE = σ / √n
SE = 13.5 / √92
SE = 1.41
So the margin of error is:
ME = 1.88 × 1.41
ME = 2.6
