1 m = 100 cm
So take 48 divided by 100 = 0.48m, so this is correct.
1 cm = 10 mm

The amount M (in trillions of dollars) of mortgage debt outstanding in the United States from 1990 through 2009 can be approximated by the function M = f(t) = 0.0037(t + 14.979)2, where t = 0 represents the year 1990.
a) Describe the transformation of the common function f(x) = x2. Then sketch the graph over the interval 0 ≤ t ≤ 19.
b) Predict the mortgage debt in the year 2014.
Answer:
The function f(t) = 0.0037(t + 14.979)^2 can be rewritten as f(t) = 0.0037(t^2 + 29.958t + 222.126). This is a quadratic function that has been stretched vertically by a factor of 0.0037 and shifted 14.979 units to the right and 222.126 units up.
To sketch the graph of this function, we can start with the graph of f(t) = t^2, which is a parabola that opens upwards. The transformation of this function stretches the parabola vertically by a factor of 0.0037, so its maximum and minimum values will be much smaller. The shift of 14.979 units to the right means that the vertex of the parabola will be located 14.979 units to the right of the vertex of the original parabola. The shift of 222.126 units up means that the minimum value of the function will be located 222.126 units above the minimum value of the original parabola.
On the interval 0 ≤ t ≤ 19, the graph of the function will be a parabola that stretches vertically by a factor of 0.0037 and is shifted 14.979 units to the right and 222.126 units up from the graph of f(t) = t^2.
To predict the mortgage debt in the year 2014, we can substitute t = 24 into the function f(t) = 0.0037(t + 14.979)^2. This gives us f(24) = 0.0037(24 + 14.979)^2 = 0.0037(39.979)^2 = 0.0037 * 1595.7441 = 5.90834 trillion dollars. This is the predicted mortgage debt in the year 2014.

Is the slope 1 /- 3 perpendicular to the slope 3?
No, the slopes are not perpendicular. The slope of 3 is three times larger than the slope of 1/-3, so the two slopes form an angle that is less than 90 degrees.
1. The slope of a line is the ratio of the vertical change to the horizontal change in the line, this is also known as the rise over run.
2. The slope of the first line is 1/-3 and the slope of the second line is 3.
3. To determine if the two slopes are perpendicular, we need to calculate the angle between them.
4. The angle between two slopes is equal to the arctan(slope1/slope2).
5. Using the formula, we can calculate the angle between the two slopes to be 63.43 degrees.
6. Since this angle is less than 90 degrees, the two slopes are not perpendicular.

the number of miles that a particular type of car can run before its battery wears out is exponentially distributed with an average of 20,000 miles. what is the probability that the car batery will die somewhere between 25000 and 30000 miles ? ( round to three decimal places )
So the probability that the car will die between 25000 and 30000 miles is P(X > 25000) = 0.286
How does probability work?Probability is a branch of mathematics that deals with numerical descriptions of the likelihood that an event will occur or that a statement is true. The probability of an event is a number between 0 and 1, where, generally speaking, 0 indicates the event's impossibility and 1 indicates its certainty.
Here,
Exponential distribution is memory less.
Let be the event of car number of miles car travels before dying out.
So mean
m = 20000
Now P(X > t) = [tex]e^{\frac{-t}{m} }[/tex]
Since P( X > [tex]\frac{(x+y)}{X > x}[/tex]) = P(X > y)
=> P(X > 25000) = [tex]e^{\frac{-25000}{20000} }[/tex]
=> P(X > 25000) = [tex]e^{\frac{-5}{4} }[/tex]
=> P(X > 25000) = 0.286
So the probability that the car will die between 25000 and 30000 miles is P(X > 25000) = 0.286

There are 4,500 cities on planet Purple. The planetary government takes a random sample of 350 cities and finds that the average number of complaints about feral cats from the sample was 3.4 ± 0.49. Which of the following is an estimate of the total number of feral cat complaints for planet Purple?
Between 1018.5 and 1361.5 complaints
Between 171.5 and 1190 complaints
Between 13,095 and 17,505 complaints
Between 2,205 and 15,300 complaints
Based on the margin of error, an estimate of the total number of feral cat complaints for planet Purple is A. Between 1018.5 and 1361.5 complaints.
What is the margin of error?The margin of error shows the statistical difference between the actual and projected or estimated results.
The margin of error gives the difference between the upper limit and the lower limit of the sample estimate.
With the margin of error, one establishes a level of confidence or the confidence interval in the sample results.
The total number of cities on planet Purple = 4,500
Random sample size = 350 cities
Average complaints = 3.4
Margin or error = ± 0.49
Upper limit = 1,361.5 [350 x (3.4 + 0.49)]
Lower limit = 1,081.5 [350 x (3.4 - 0.49)]
Thus, using the margin of error, an estimate of feral cat complaints hovers over Option A.

A line has a slope of negative one-fourth and passes through point (negative five-fourths, 1). What is the equation of the line?.
The equation of the line is y - 1 = -1/4( x + 5/4).
Here we have to find the equation of the line.
Data given:
Point on the line= (-5/4, 1)
slope(m) = -1/4
The formula of the equation of the line:
y - y1 = m(x - x1)
where m = slope of the line
(x1, y1) = point on the line
Now putting the values in the equation we have:
y - 1 = -1/4( x- (-5/4))
y - 1 = -1/4( x + 5/4)
Therefore the equation of the line is y-1 = -1/4( x + 5/4).

family music your family has an ipod filled with music. it has many thousands of songs. you figure that roughly 60% of the songs are music you like, 25% of the music is annoying songs from your little sister, and the rest is stuff from the 80s that only your parents still think is cool. driving across town, your mom puts the ipod on shuffle and you all listen to whatever randomness produces. what is the probability that the first song is a) an 80s song? b) a song picked by one of the kids? c) not one of your songs?
Step-by-step explanation:
If the iPod has many thousands of songs, it's safe to assume that the number of 80s songs, songs picked by one of the kids, and songs that you like are all significant. Therefore, the probabilities that the first song will be an 80s song, a song picked by one of the kids, or not one of your songs are roughly equal to the percentage of each type of song on the iPod.
For example, the probability that the first song will be an 80s song is roughly 15%, since only 15% of the songs on the iPod are 80s songs (80s songs make up 100% - 60% - 25% = 15% of the iPod's music). Similarly, the probability that the first song will be a song picked by one of the kids is roughly 25%, and the probability that the first song will not be one of your songs is roughly 40% (100% - 60% = 40%).
Note that these probabilities are only approximate, since the songs on the iPod are chosen randomly and the actual probabilities may vary slightly.

A combination is a choice made in mathematics from a group of different elements when the order of the choices is irrelevant (unlike permutations). For instance, if three fruits, such as an apple, an orange, and a pear, are supplied, there are three possible pairings of the two: an apple and a pear. Formally speaking, a k-combination of a set S is a subset of S's k unique components. In other words, two combinations are the same if and only if they have the same members.
