Laura has a backyard that she wants to renovate. Her
miskamm [114]

Answer:

Area of the walkway = 8<em>x </em>+ 24

Step-by-step explanation:

Area of the total backyard = l\times b

Area of total backyard = (x+6)\times (x+4) = x^{2} +10x + 24

Now, Area of the rectangular garden = l\times b

Area of the rectangular garden = x (x+2) = x^{2} + 2x

Now area of the walkway poured with concrete = Area of the backyard - Area of the rectangular garden

= (x^{2} +10x +24) - (x^{2} +2x)

= x^{2} + 10x +24 - x^{2} -2x

= 8<em>x</em> + 24

Laura babysat 8 nights during the month of July. She earned $22, $30, $35, $25, $25, $20, and $27 for seven nights. How much did
Svet_ta [14]

Answer:

$28

Step-by-step explanation:

Given:

data = [22,30,35,25,25,20,27]

For eight night, the new list is:

new_data = [22,30,35,25,25,20,27,x]

Mean = 26.50

Mean Formula:

\displaystyle \large{m=\dfrac{x_1+x_2+x_3+...+x_n}{n} }

Therefore:

\displaystyle \large{26.50=\dfrac{22+30+35+25+25+20+27+x}{8}}

Multiply both sides by 8:

\displaystyle \large{26.50\cdot 8=\dfrac{22+30+35+25+25+20+27+x}{8} \cdot 8}\\\displaystyle \large{212=22+30+35+25+25+20+27+x}

Solve for x:

\displaystyle \large{212=22+30+35+25+25+20+27+x}\\\displaystyle \large{212=184+x}

Subtract 184 both sides:

\displaystyle \large{212-184=184+x-184}\\\displaystyle \large{28=x}

Therefore, she will earn $28 in eighth night

The attachment below is the result of combining all eighth data as we get 26.5 through python language with numpy package.
