Answer:

a = 9

Step-by-step explanation:

Given

\frac{2(a-3)}{3} = 4 ( multiply both sides by 3 to clear the fraction

2(a - 3) = 12 ( divide both sides by 2 )

a - 3 = 6 ( add 3 to both sides )

a = 9

As a check substitute a = 9 into the left side of the equation and if equal to the right side then it is the solution.

\frac{2(9-3)}{3} = \frac{2(6)}{3} = \frac{12}{3} = 4 = right side

Thus solution is a = 9

2(a - 3). = 4

_______

3

Cross multiply.

2(a- 3) = 12

2a - 6 = 12

2a = 12 + 6

2a = 18

a = 18 ÷ 2

a = 9

Use the data from problem:
navik [9.2K]

Answer:

a) Sample mean: 48.71

Sample median: 48.3

Sample variance: 5.41

Sample standard deviation: 2.37

Step-by-step explanation:

a) Sample mean:

\bar{X}=\frac{1}{N} \sum X_i=\frac{1}{80}*3896.9=48.71

Sample median: M=48.3

Note: I order the data increasingly and take the value N / 2 = 40. In this way there are 39 values above and 39 values below the median.

Sample variance:

s^2=\frac{1}{N-1}\sum (X_i-\bar X)^2 =(\frac{1}{80-1})*427.74=5.41

Sample standard deviation

s=\sqrt{s^2}=\sqrt{5.41}=2.37
