For this case we have an exponential equation of the form:
Where,
- <em>A: initial value
</em>
- <em>b: decrease rate
</em>
- <em>x: number of years
</em>
Substituting values in the given equation we have:
Answer:
The value of the car after 15 days is given by:
The total number of possible combinations to make a three digit number is 60
<u>Explanation:</u>
Given:
Five numbers are there = 1, 2, 3, 4, 5
We have to form three digit number
The number should not be repeated
Consider 3 dashes for 3 digits : ___ ___ ___
The first dash can be occupied by any 5 digits.
The second dash can be occupied by 4 digits
The third dash can be occupied by 3 digits
Thus, number of possible combinations to make a three digit number is
= 5 X 4 X 3
= 60
Therefore, total number of possible combinations to make a three digit number is 60
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:
The following is NOT TRUE about the normal distribution, that is, d.) The curve is right-skewed(that is, skewed to the right).
Step-by-step explanation:
In a normal distribution the properties of which are given as follows:
i) all the central tendency measures, that is, the mean, the median and the mode are equal.
ii) The area under the bell curve is equal to one.
iii.) The bell curve is symmetric about the center, or mean.
iv.) The bell curve does not touch the x - axis.
Therefore only the following is NOT TRUE about the normal distribution, that is, d.) The curve is right-skewed (that is, skewed to the right).
Answer:
true for sure it \s pretty easy to do but hard to explain
