Answer:

<em>La media aritmética es 2.3</em>

Step-by-step explanation:

<u>Average o Promedio</u>

El promerio, average, o valor medio es un valor representativo de un conjunto de datos y se calcula según la fórmula:

\displaystyle \bar x=\frac{\sum x_i}{n}

Donde xi es el valor de cada dato, y n es el número de datos.

Los datos presentados son:

1, 4, 1, 1, 4, 2, 3, 1, 4, 2

Nótese que hay un total de n=10 datos. Aplicamos la fórmula recordando que el símbolo Σ significa <em>sumatoria</em>:

\displaystyle \bar x=\frac{1+ 4+ 1+ 1+ 4+ 2+ 3+ 1+ 4+ 2}{10}

\displaystyle \bar x=\frac{23}{10}=2.3

La media aritmética es 2.3

Four friends want to take a vacation together, so each one gets a prat-time job. Each person has 6 weeks to save $750 for the va
vladimir2022 [97]

Answer:

Only Friend A and Friend B met the target of saving $750 for their vacation

Step-by-step explanation:

From the question, we are to find out who achieved their goal of saving $750 in 6 weeks. We would analyse the options we were given

Friend A: Works 20 hours per week at $6.95 per hour.

1 week = 20 hours

6 weeks = 20 × 6

= 120 hours

The friend each $6.95 per hours earns, the amount earned in 6 weeks =

120 hours × $6.95

= $834

Friend A met the target

Friend B: Works 25 hours per week at $5.85 per hour.

1 week = 20 hours

6 weeks = 25 × 6

= 150hours

The friend each $5.85 per hours earns, the amount earned in 6 weeks =

150 hours × $5.85

= $877.5

Friend B met the target of saving $750.

Friend C: Works 15 hours per week at $8.25 per hour.

1 week = 15 hours

6 weeks = 15 × 6

= 90hours

The friend each $8.25 per hour earns, the amount earned in 6 weeks =

90 hours × $8.25

= $742.5

Friend D did not meet the target of saving $750

Friend D: Works 11 hours per week at $10.80 per hour.

1 week = 11 hours

6 weeks = 11 × 6

= 66 hours

The friend each $10.80 per hour earns, the amount earned in 6 weeks =

66 hours × $10.80

= $712.8

Friend D did not meet the target of saving $750

Therefore, from the above calculation, only Friend A and Friend B met the target of saving $750 for their vacation.
