“You are collecting email addresses from 74 customers per day, which is about 90% of the daily goal of emails per day.”

2 answers:

6 0

We apply the formula part ÷ percent to determine the total.

74 ÷ 0.9 = 82.222222
Therefore, approximately 82 emails are needed to meet the goal.

An equation can be set up to find the daily email target:

74 = 0.90 × x, where x represents the daily goal.

By dividing both sides by 0.90, x equals 82.222. Rounding down, the goal is 82 emails.

A journalist wants to determine the average annual salary of CEOs in the S&P 1,500. He does not have time to survey all 1,50

Inessa [12570]

Answer:

At least 315

Step-by-step explanation:

A journalist intends to find the average annual salary of CEOs within the S&P 1,500. Due to time constraints, a sample is used.

Standard deviation of the sample (s) = 449300

Sample size = n

Permissible margin of error = 50000

Z critical value = 1.96

Thus, 1.96 times the standard error equals 50000.

Standard error equals 25510.20

Standard deviation divided by the square root of n = 25510.20

By simplifying, we can derive:

$\sqrt{n} =\frac{449300}{25510.20} =17.752\\n=315\\$

Thus, the minimum sample size required is 315.

Brad buys a pack of 12 bottles of energy drink for £9.25 he then sells all bottles for £1 each. Work out brads percentage profit

Svet_ta [12734]

La ganancia de Brad fue del 30%

Explicación adicional:

La ganancia es el dinero obtenido al vender un producto por encima de su costo original.

La fórmula para calcular la ganancia es:

$Profit= Selling\ price-Purchase\ price$

Datos:

Precio de compra del paquete de bebidas energéticas = £9.25

Precio de venta por botella = £1

Precio total por 12 botellas = 1 * 12 = £12

Ganancia = Precio de venta - Precio de compra

= 12 - 9.25

= £2.75

Así, la ganancia de Brad fue de £2.75

Luego,

Porcentaje de ganancia = (Ganancia / Precio de compra) * 100

= (2.75 / 9.25) * 100

= 0.30 * 100

= 30%

La ganancia de Brad fue del 30%
