Answer:
1.65%
Step-by-step explanation:
We will assume the percentage was the same over the 5 years. The number of passengers using a railway is expressed by the formula
Where
P(t) is the number of passengers after 5 years
P(t) = 174,989
P₀ is the number of the passengers at the beginning of the period
P₀ = 190,205
r is the rate in percentage r = ?
t is time duration t = 5 years
Substituting these given values into the formula,
![1 - r = \sqrt[5]{ \frac {174,989}{190,205}}](https://tex.z-dn.net/?f=1%20-%20r%20%3D%20%5Csqrt%5B5%5D%7B%20%5Cfrac%20%7B174%2C989%7D%7B190%2C205%7D%7D)
![1 - r = \sqrt[5]{0.920}](https://tex.z-dn.net/?f=1%20-%20r%20%3D%20%5Csqrt%5B5%5D%7B0.920%7D)
r = 1.65%
The annual percentage decrease over the period of 5 years is 1.65%
Answer:no
Step-by-step explanation:
first, you watch anime so your already big brain, you also watch that Luffy show which is old so your old so your smart...logic. Another reason is that your user name is "Key Master" referring to the og ghostbusters which is old. Now we know that you have more knowledge(cuz you've been on earth longer, also it says your in middle school) your smart.
Step-by-step explanation:
x = number of true/false questions
y = number of multiple choice questions
x + y = 40
2x + 3y = 144
from the first equation we get
x = -y + 40
this identity we can then use in the second equation
2(-y + 40) + 3y = 144
-2y + 80 + 3y = 144
y + 80 = 144
y = 64
and
x + 64 = 40
x = -24
that does not make any sense.
something is wrong with the problem description.
just think about it :
40 questions - if all of them would be multiple choice tests (creating the max. possible points for 40 questions), we could have only 40×3 = 120 points.
but the description says 144 points.
for 144 points we need at least 48 (144/3) questions.
that does not fit.
the described system does not have any natural number solution. therefore we are getting such crazy numbers as result, when we try.
Answer:
Step-by-step explanation:
Good question. It is important to know the answer.
The 9 means that there are a total of 20 objects. You want to select just 9 of them.
The situation is well described by C.
Take the first graph and translate it UP 20 units.
