Answer: 14

Step-by-step explanation:

Step 1: Substitute the x and y values:

[tex]\frac{4^3-2^3}{4}[/tex]

Step 2: Find 4 to the power of 3.

4 x 4 x 4 = 64

Now find 2 to the power of 3

2 x 2 x 2 = 8

Step 3: Subtract the two values as mentioned in the equation:

64 - 8 = 56

Step 4: Now divide 56 by 4 as mentioned in the equation.

56 ÷ 4 = 14

And... 14 is the answer!

Answers

Answer:

it depends on the work place to play it safe i would choose 12

Step-by-step explanation:

The sample mean is equal to 24 and population mean is equal to 25

What is sample mean?

Sample mean represents the measure of the center of the data. The sample mean formula is used to calculate the average value of the given sample data.

Sample mean= sum of the terms/number of the terms

What is population?

The population in static is used for a collection of data. The population mean can be calculated by the sum of all values in the given population divided by a total number of values in the given population.

Population mean= sum of the population/ number of the population

From the given question average of entire year is 25.

According to the population mean formula the sum of the population by number of the population is nothing but the average of the entire year. Thus the population mean is 25.

According to the sample mean formula,

sample mean= sum of the terms / number of the terms

⇒(25+10+16+39+27+25+32+25+25+22+28+14)/12 = 24

Thus the sample mean is equal to 24 and population mean is equal to 25

It seemed as though the strong wings had begun to lose their power. Like a wounded bird Icarus fluttered, lunged sidewise from the straight, clean line of his flight, recovered himself, and fluttered again. And then, like the bird into whose soft breast the sure hand of a mighty archer has driven an arrow, downwards he fell, turning over and yet turning again, downwards, ever downwards, until he fell with a plunge into the sea that still was radiant in shining emerald and translucent blue.Then the car of Apollo drove on. His rays had slain one who was too greatly daring, and now they shone on the little white feathers that had fallen from the broken wings and floated on the water like the petals of a torn flower.Stricken at heart was Daedalus, but there was no time to lament his sons untimely end, for even now the ships of Minos might be in pursuit.
