|x+2| - 3 = 9

Option 1:

x + 2 - 3 = 9

x - 1 = 9   <em>  add 1</em>

x = 9 + 1

x = 10

Option 2:

-(x+2) - 3 = 9  <em>Distribute "-" through the parenthesis </em>

-x - 2 - 3 = 9

-x - 5 = 9     <em>Add 5</em>

-x = 9 + 5

-x = 14   <em>Multiply by -1</em>

x = -14

Which expression is equivalent to 5.4+3.4w-1.8w +5.8 A) 7(1.6+w) B) 1.6(7+w) C) 1.6(7w) D) 1.6(0.25+w)
Bad White [126]
Do 5.4 plus 5.8 then do 3.4w minus 1.8w and whatever you get for each is your key to the expression. So if you were to solve the answers like A you would do 7(1.6+w) and see what you would get. Obviously A isn't the answer. Sorry, this is hard to explain. But the answer is C

The standard deviation<u> </u><u>INCREASES</u>

Step-by-step explanation:

Standard deviation is used to show how the points of the data deviate from the mean. The formulae for deriving standard deviation is attached. As seen from the formulae, the greater the variance of the data from the mean, the higher the Standard Deviation.

The mean of the given data points is $103.4. $450 is way off from this mean meaning that there is a large variance in this data point.

Assume that we are interested in the average length of 1015 fishes in Square Lake, WI. Also assume that all information for all
zimovet [89]

Answer is given below

Step-by-step explanation:

given data

average length of all 1015 fishes = 98.06 mm

randomly selects 50 fishes average length = 101.04 mm

solution

  • When we get here, we mean to measure, so here we measure a fish in a square lake.
  • And the variable means that a fish varies from fish to fish, so the length of the fish in the squares
  • parameter mean that all individuals in the population so the parameter is average length of all 1015 fish in square lake
  • statics is selct of individual in sample so statistic is average length of random sected so fish in square lake
