Dafna1 [17]

Answer:

<em>Answer is</em><em> </em><em>given</em><em> </em><em>below with explanations</em><em>. </em>

Step-by-step explanation:

$given \: \: l = 5x - y \: and \: \: b = x + 4y \\ area \: of \: rectangle \:= l \times b \: sq.units \\ = (5x - y)(x + 4y) \\ = 5 {x}^{2} + 20xy - xy - 4 {y}^{2} \\ = 5 {x}^{2} + 19xy - 4 {y}^{2} \\ perimeter \: of \: rectangle \\ = 2(l + b) \\ = 2(5x - y + x + 4y) \\ = 2(6x + 3y) \\ = 12x + 6y$

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

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

$E(x)=9-8$

$E(x)=1$
