PLEASE HELP !!! - after tip you gave a total of $321.75. If the original price of the meal was $300, what percent tip was applie
yan [13]

Answer: 7.25%

Step-by-step explanation:

There are a few ways to do this, but the easiest might be to set up a proportion:

321.75/300 = x percent/100 percent

Now cross multiply;

300x = 321.75(100) = 32,175

Divide both sides by 300 to solve for x:

300x/300 = 32,175/300

x = 107.25 This means that the tip was 7.25% on top of the $300 meal.

jasenka [17]

The sample size of 36 will produce the widest 95% confidence interval when estimating the population parameter option (b) is correct.

<h3>What are population and sample?</h3>

It is described as a collection of data with the same entity that is linked to a problem. The sample is a subset of the population, yet it is still a part of it.

We have:

A sample has a sample proportion of 0.3.

Level of confidence = 95%

At the same confidence level, the larger the sample size, the narrower the confidence interval.

As we have a 95% confidence interval the sample size should be lower.

The sample size from the option = 36 (lower value)

Thus, the sample size of 36 will produce the widest 95% confidence interval when estimating the population parameter option (b) is correct.

Si consideras como base uno de los rectángulos de dimensiones de 5cm y 3cm ¿cuanto mide la altura de ese prisma?
Vinvika [58]

Respuesta:

h = V / 15

Explicación paso a paso:

El volumen de un prisma rectangular se calcula usando la relación:

Largo ancho alto

Donde, largo y ancho son la dimensión de la base

Por eso,

Volumen = Base * altura

Volumen = (5 cm * 3 cm) * altura

De la pregunta, no se da el volumen, por lo tanto, tomamos el volumen como V en otro para calcular la altura, h

V = 15h

Divide ambos lados entre 15

V / 15 = 15h / 15

V / 15 = h
