Marizza181 [45]
Hi there! An equation for this problem would look something like

12d=75

Since the farmer can harvest 12 acres per day, the variable d represents days. 12 times the number of days it would take to harvest the field would equal 75.

Coefficient definition
Naily [24]

Answer:

In mathematics, a coefficient is a factor linked to a monomium. Given a monomium divider, the coefficient is the ratio of the monomium by the divider. Thus the monomium is the product of the coefficient and the divider. The different coefficients will depend on the factorization of the monomium. This is usually next to the letter that accompanies the algebraic fraction. A numeric coefficient is a constant factor of a specific object. For example, in the expression 9x2, the coefficient of x2 is 9. In elemental algebra, numeric coefficients of similar terms are grouped together to simplify algebraic expressions.

Calculate the mean. 4, 5, 7, 7, 9, 12, 15, 20
Semmy [17]

Answer:

Mean: 9.875

Median: 8

Mode: 7

Minimum: 4

Maximum: 20

Range: 16

Size: 8

Sum: 79

Step-by-step explanation:

How to find the mean?

1. Count the number N of data points in your data set.

2. Sum up all of the data points in your data set (add them all together).

3. Average = Mean = Sum/N.

How to find the median ?

The median is the numeric value separating the upper half of a sample data set from the lower half. The median of a data set can be found by arranging all the values from lowest to highest value and picking the one in the middle. If there is an odd number of data values then the median will be the value in the middle. If there is an even number of data values the median is the mean of the two data values in the middle.

For the data set 1, 1, 2, 5, 6, 6, 9 the median is 5.

For the data set 1, 1, 2, 6, 6, 9 the median is 4. It is the mean of 2 and 6 or, (2+6)/2 = 4.

How to find the mode

Mode is the value or values in the data set that occur most frequently.  

For the data set 1, 1, 2, 5, 6, 6, 9 the mode is 1 and also 6.

Hope this helps you! :D
