With respect to conducting a situation analysis, what does the phrase "Analysis alone is not a solution" mean?
nikklg [1K]

Answer: Analysis alone is not sufficient because a relationship should be made between a persons instinct and his judgement of matters to arrive at a useful conclusion.

Step-by-step explanation:

While it is necessary to conduct a situation analysis, it is also important to note that a situation analysis on its own is not enough because there should be a relationship drawn between good judgment and instinct so as to make the outcome of the analysis relevant when making important decisions.

For a situation analysis to be effective, information must be broken down sufficiently into bits so as to have a proper understanding as to why organizations, customers, and individuals behave or work the way they do. After these things are thoroughly understood, then the decision maker can make a more effective decision.

The number of girls in Mrs. Manning’s classes was 12 less than twice the number of boys. She had a total of 108 students in her
FromTheMoon [43]

40 boys and 68 girls

let's start with variables and an equation.

boys: x

girls: 2x - 12

and we know that boys and girls make up the class. so let's add the two expressions.

x + 2x - 12 = 108

3x - 12 = 108

    + 12     + 12

3x = 120

x = 40 boys

BUT x is only the number of BOYS in the class. so we have to find girls now. let's plug in our value of x into the girls' equation.

2x - 12 = # of girls

2(40) -12 = # of girls

80 - 12 = # of girls

68 girls

let's check our answer!

68 + 40 does in fact add to 108, therefore our answer is correct.

Gnesinka [82]

Answer:

5 hours

Step-by-step explanation:

Our goal here is 3 F because 82+3=85

Ok so you start at 82. For example, you can do 0.6×1=0.6 (no)

0.6×2=1.2 (no)

0.6×3=1.8 (no)

0.6×4=2.4 (no)

0.6×5=3 (yes)

82°+3°=85°
