Working backwards, on Wednesday morning we have 60 / (1/2) = 120 pounds of ice.

2/3 melts on Tuesday so 120 pounds must be 1/3 of the ice.

120 / (1/3) = 360

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.
