Find the mean of this data set: {– 78, -12, 3, – 44}

blagie [28]

Answer:

<u>Answer</u><u>:</u><u> </u><u>A</u><u>.</u><u> </u><u>-</u><u>3</u><u>2</u><u>.</u><u>7</u><u>5</u>

$\dashrightarrow{ \tt{mean = \frac{ \sum f(n)}{n} }} \\$

• f(n) are the values of the set

• n is the number of items

$\dashrightarrow \: { \tt{mean = \frac{ - 78 + ( - 12) + 3 + ( - 44)}{4} }} \\ \\ \dashrightarrow \: { \tt{ \frac{ - 131}{4} }} \\ \\ \dashrightarrow \: { \boxed{ \tt{mean = - 32.75}}}$

kifflom [539]

Answer:

$792\ \text{pounds}$

Step-by-step explanation:

$x_1=70$ cubic feet of fertilizer is used in $y_1=770$ pounds of strawberries

$x_2=90$ cubic feet of fertilizer is used in $y_2=990$ pounds of strawberries

$x=72$ cubic feet of fertilizer is used

Linear interpolation is applied

$y=y_1+\dfrac{(x-x_1)(y_2-y_1)}{x_2-x_1}\\\Rightarrow y=770+\dfrac{(72-70)(990-770)}{90-70}\\\Rightarrow y=792\ \text{pounds}$

72 cubic feet of fertilizer will yield $792\ \text{pounds}$ of strawberries.
