Cual es la simplificacion de 66/81

Karo-lina-s [1.5K]

Answer:

Hence the simplification of $\dfrac{66}{81}$ is $\dfrac{22}{27}$

Step-by-step explanation:

" Simplification is the process of replacing a mathematical expression by an equivalent one, that is simpler (usually shorter),

for example: Simplification of a fraction to an irreducible fraction ".

Here we are given a fraction as:

$\dfrac{66}{81}$

As both the numerator and denominator are divisible by a factor of 3 hence we take out the common factor and obtain the reduced fraction which is further irreducible.

As 66=3×22 and 81=3×27

Hence $\dfrac{66}{81}=\dfrac{3\times22}{3\times27}=\dfrac{22}{27}$

Hence the simplification of $\dfrac{66}{81}$ is $\dfrac{22}{27}$

Suppose the mean height in inches of all 9th grade students at one high school is estimated. The population standard deviation i

Mnenie [13.5K]

Answer:

The population mean = sample mean = x`= 67.5

Population standard deviation = 13.369

Sample standard deviation= 4.225

Step-by-step explanation:

AS the population mean is not given we will calculate it from the sample.

The mean of the sampling distribution is equal to the population mean .

The sample mean is calculated by

x`= ∑x/n= 75,+ 62, +69,+65,+66,+64, +67,+70,+74 + 63/10

x`=675/10= 67.5

The standard deviation of the sample is equal to

u = σ/ √n where σ is the population standard deviation and n is the number of observations.

Calculating the sample mean

s= √∑xi²/n- (∑x/n)²

s= √(45741/10)- (675/10)²

s= 4.2249

σ= u*√n= 4.229 *√10

σ=13.360
