Solve for k, m = 3kx/7 - 9

kap26 [50]

Answer:

(7m + 63)/3x = k

Step-by-step explanation:

m=3kx/7 - 9

add 9 to both sides:

m+ 9 = 3kx/7

multiply both sides by 7:

7(m+9) = 3kx

distribute the 7:

7m+63 = 3kx

divide both sides by 3x:

(7m + 63)/3x = k

Exhibit 10-7 In order to estimate the difference between the average hourly wages of employees of two branches of a department s

Leokris [45]

Answer:

$E(x)=1$

Step-by-step explanation:

From the question we are told that:

Sample mean 1 $\=x_1=$9$

Sample mean 1 $\=x_2=$8$

Sample standard deviation 1 $\sigma_1 = $2$

Sample standard deviation 1 $\sigma_2 = $1$

Generally the equation for Point estimate is mathematically given by

$E(x)=\=x_1-\=x_2$

$E(x)=9-8$

$E(x)=1$
