A survey in 2012 indicated that college freshmen carry a mean credit card debt of $611 but the median of their credit card debt is $47. Create a data set of five freshmen students so that the data set has a mean and median that is the same as that of the surveyed college freshmen. , , , ,
Answer:
$27, $30, $47, $1093, $1851
Step-by-step explanation:
The median is the middle number and the mean is the average. When averaging all the numbers above, you get 611 and the middle number is 47.
The possible data set is $27, $30, $47, $1093, and $1851.
What is the mean?The average of a group of variables is referred to as the mean in mathematics and statistics. There are several methods for calculating the mean, including simple arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means.
To create a data set of five freshmen students with the same mean and median as the surveyed college freshmen:
Arrange the five numbers in ascending order to create the data set.
For example, one possible data set is:
$27, $30, $47, $1093, $1851
The mean of this data set is (28+ 40 + 47 + 1090 + 1850) / 5 = $611, which is the same as the mean of the surveyed college freshmen.
The median of this data set is 47, which is also the same as the median of the surveyed college freshmen.
Therefore, $27, $30, $47, $1093, and $1851 are the points of the data set.

Step-by-step explanation:
The slack variables make up the difference between the sum of the utilizations and the limit. A separate slack variable is needed for each limit. As with the other variables, its minimum value is zero.
For ( ) ≤ lim constraints, the slack variables are on the left side of the equal sign:
( ) +s ≤ lim.
__
For ( ) ≥ lim constraints, the slack variables can be on the right side of the equal sign:
( ) = s + lim
The more usual representation in a linear programming matrix is ...
( ) - s = lim
__
Here, your constraints are "≤", so each equation will have a unique slack variable added to the left side sum.
Which equation represents a line that has a slope of One-third and passes through point (–2, 1)?

Find the Greatest Common Factor and Least Common Multiple for 20 and 8. GCF is LCM
Answer:
GCF= 4 LCM=40
Step-by-step explanation:
Factors of 8:1,2,4,8
Factors of 20:1,2,4,5,10,20
Greatest common factor is 4 because it is the highest factor in both sets.
Multiples of 8:8,16,24,32,40,48,56,64,72,80...etc
Multiples of 20:20,40,60,80,100,120,140...etc
Lowest common multiple is 40 because it is the lowest multiple in both sets.

in one week katy walks 1,720 meters and runs 1,925 meters. she performs the same workouts for three weeks. how many meters does katy walk and run in three weeks of workouts?
Answer:
10,935 meters.
Step-by-step explanation:
Find how many meters she walks in 1 week, so you add the 1,720 and the 1,925 and you would get 3,645. If she does the same thing for 3 weeks, you multiply the 3,645 by 3, so you get 10,935 meters

I'm pretty sure it would be 2 and 90, let me know if I'm wrong.
Answer:
2, 90
Step-by-step explanation:
Divide 54 by 3 to get how many licks are needed for ONE lollipop. Once you figure how many licks are needed for ONE, you can figure out how many it takes for any amount of lollipops.
54 licks / 3 lollipops = 18 licks / 1 lollipop
Divide 36 by 18 and multiply the quotient by 18 to find the number of lollipops 36 licks takes.
36 licks / 18 licks = 2 lollipops (this is your first answer)
Now multiply 18 by 5 like so: 18 * 5 = 90 (this is your second answer)

What is summation?A summation, also abbreviated as a sum, is the outcome of adding two or more numbers or quantities. Here are always an integer number of terms in a summation. There could be only two terms, but there could be one hundred, thousand, or a million. There are summations with an infinite set of parameters.
In another word, the summation is to add or subtract any two or more terms by doing that operation we will get a new result which could be big or small depending upon the number.
Given the inventory 2, 4, 2,5,3,1 if we add this inventory to the total then it will come out to be
2+ 4+ 2+5+3+1 =17 hence 17 will be the correct answer.

What is the exponential function rule for the following points
x f(x)
1 8
2 32
3 128
4 512
Answer:
y=2(4^x)
Step-by-step explanation:
if you notice, all the y-values are multiplied by 4 for each x-value. this means 4 is raised to the power of x. however, when you plug this in, you realize that the value produced is only half the actual y-values, so you multiply this whole thing by 2.
y=2(4^x)
Answer:
f(x) = 2^(2x+1)
Step-by-step explanation:
You can tell that each of the outputs of f(x) are powers of 2, so all you have to do is figure out the pattern of the exponents.
2^3 = 8
2^5 = 32
2^7 = 128
2^9 = 512
