It says that the buildings together are 200 meters high and from the top pf the first to bottom of the second is 20(whole building) but from the top of the first to second is 10 (half of the building ) so if the degree if half the high will be half too so the high will be 200/2 = 100 meters high for each buildings :))
i hope this is helpful
have a nice day
Answer: Cody rented the bike for 7 hours.
Step-by-step explanation:
$65-$16=$49
$49/$7=7 hours
4/28 = 1/7 when dividing both numerator & denominator by 4 and this would be the simplified fraction.
You could use 1/7 to multiply with others to get other ratios that are equal to 4/28 or you could just use 4/28.
For example:
1/7 = 7/49
or
4/28 = 8/56

Answer:
The answer is below
Step-by-step explanation:
From the table, the mean (μ) = 1390.75 and the standard deviation (σ) = 518.75
The confidence level (C) = 90% = 0.9
α = 1 - C = 1 - 0.9 = 0.1
α/2 = 0.1 / 2 = 0.05
The z score of α/2 (0.05) is the same as the z score of 0.45 (0.5 - 0.05) which is equal to 1.645.
The margin of error (E) is given as:
The confidence interval = μ ± E = 1390.75 ± 228.07 = (1162.68, 1618.82)
The confidence interval is between 1162.68 and 1618.82.
