Answer:
The homeowner will require 9 strips of wallpaper.
Step-by-step explanation:
The question is asking <em>"how many 20 inches fit into 15 feet?".</em>
We know that
1 foot = 12 inches;
therefore, 15 feet will be
15 ft * 12 in/ft = 180 in.
Now, the number of 20 inches wallpaper strips that will fit into 180 in long wall will be
180 in/ 20 in = 9
Therefore, the homeowner will require 9 strips of wallpaper.
The left side was cut out but x will be on top and 5 in the lower square. The last one is the answer.
Answer:
0.20148
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 230
μ is the population mean = 184
σ is the population standard deviation = 55
z = 230 - 184/55
z = 0.83636
P-value from Z-Table:
P(x<230) = 0.79852
P(x>230) = 1 - P(x<230) = 0.20148
Therefore, the probability that the eye contact time is greater than 230 seconds is 0.20148
