Answer:

NO SOLUTION

Step-by-step explanation:

Let's actually solve the system

x-4y=1

5x-20y=4

Let's eliminate y.  To do this, multiply the first equation by -5, obtaining

-5x + 20y = -5

Now add this result to the second equation:

-5x + 20y = -5

5x -  20y =  4

--------------------

           0   = -1

This result is never true.  Thus, this system of linear equations has NO SOLUTION.

1. A breakfast cereal is made of oats, nuts, and raisins. The advertisements boast that 25% of the cereal in each box is almonds
kotykmax [81]

Answer:

Step-by-step explanation:

1) The advertisements boast that 25% of the cereal in each box is almonds. It means that the percentage of the other cereals in the box is 100 - 25= 75%

Therefore, the portion of each box that is not almonds is 75/100 = 0.75

2) The advertisements boast that 25% of the cereal in each box is almonds. If each box contains 12 cups of cereal, then the number of cups of almonds in each box is

25/100 × 12 = 3 cups

3) if each box contains 12 cups of cereal, and 4 cups are oats, then the percentage of each box that is oats is

4/12 × 100 = 33.33%

The following set of data represents letter grades on term papers in a rhetoric class: A,A,A,B,B,B,B,C,C,C,C,C,C,C,C,C,D,D,D,F.
Viktor [21]

Answer:

c. Mode

Step-by-step explanation:

Mean is the average obtained by adding all values and then dividing by the size of the values. Here, adding A and B etc is not clear.

Median is the middle value of a set of numeric values. To find a median, values should be sort-able from smallest to the largest. If there is no unique middle value, then the average of the middle values has to be taken. Here, average of the two different grades is not clear.

Mode is the value that occurs most often. Clearly C occurs most often.

Mid-range value is the mean of the difference between largest value and the smallest value. Here, difference between A and F is not clear.

Mean,median,Mid-range are applied to numeric values where mode is also suitable for categorical values.

Therefore, the most appropriate measure of central tendency for the data described is mode
