Answer:
d. inputs decrease while outputs remain the same -- True here productivity increases.
Step-by-step explanation:
In any organization productivity is a measure of efficiency
Productivity is normally expressed as ratio of output/input
Obviously when output increases productivity increases and also
when input decreases productivity increases.
a. inputs and outputs increase proportionately -- False here no change.
b. outputs decrease while inputs remain the same -- False here productivity decreases.
c. inputs increase while output remains the same -- False here productivity decreases.
d. inputs decrease while outputs remain the same -- True here productivity increases.
Answer:
The value of Mode is 2.43
Step-by-step explanation:
- To find the mode of the given data first we have to arrange it in a increasing order then find out mean and median of the given data
- 0.7,1.7,3,3.2,4.1,5.9,6.6,8.9 is in increasing order
- For finding the median we need to take the average of 4th and 5th terms because we have the no of terms in the sequence is even not odd so we need to take the average the 4th term=3.2 and the 5th term =4.1
- so average =(3.2+4.1)/2=3.65
- so the median is equal to 3.65
- For mean we have to take the average of the data
- so mean= sum of all data /no of data
- mean =(0.7+1.7+3+3.2+4.1+5.9+6.6+8.9)/8=4.26
- so by using the formula we can get mode
- <em>Mode=3×Median-2×Mean</em>
- Mode=3×3.65-2×4.26=2.43
- ∴The value of Mode is given as 2.43
To find the solution we will first find the difference between each number and mean, and then substitute the value in the formula of standard deviation.
The standard deviation is 8.4477 and the variance is 71.40.
Given to us
- Test scores of Adimas = (76, 87, 65, 88, 67, 84, 77, 82, 91, 85, 90)
- Mean = 81
<h3>Standard Deviation</h3>
difference between each number and mean,
= 25 + 36 + 256 + 49 + 196 + 9 + 16 + 1 + 100 +16 + 81
= 785
<h3>Variance</h3>
Variance = 
= 71.40
Hence, the standard deviation is 8.4477 and the variance is 71.40.

Explanation:
The x value can not repeat but the y value can
Answer:
The factor form is 
Step-by-step explanation:
When it is required to factor the expression given in the problem, we have to first find a common term or terms, which will be found by either grouping the like terms or the splitting of the terms.
Now the expression that is given here is:
Now, here we will take:
Thus we will get:
Now we will do the middle term split as follows:
Substituting back , we will have:
Hence, the required factor form of the given expression will be:
