Answer:

<u>Poloma’s equation has a positive slope, but the scatter-plot has a negative correlation.</u>

Step-by-step explanation:

The scatter-plot is as shown in the attached figure.

As shown in the figure, the scatter-plot has a negative correlation.

And the equation of Poloma is y = 5/6x - 31/6

Where the slope of the line = 5/6 and y-intercept = -31/6

According to the previous information, the true statement is:

Poloma’s equation has a positive slope, but the scatter-plot has a negative correlation.

Una torre de 28.2 m de altura esta situada a la orilla de un rio, desde lo alto del edificio el ángulo de depresión a la orilla
Svet_ta [14]

Answer:

El ancho del río es 59.9 metros.

Step-by-step explanation:

El ancho del río lo podemos calcular con la siguiente relación trigonométrica asumiendo que la torre forma un triángulo rectángulo con el río:

tan(\theta) = \frac{CO}{CA}

En donde:

CA: es el cateto adyacente = Altura de la torre = 28.2 m

CO: es el cateto opuesto = ancho del río =?

θ: es el ángulo adyacente a CA

Dado que el ángulo de depresión (25.2°) está ubicado fuera de la parte superior de la hipotenusa del triángulo que forma la torre con la orilla opuesta del río, debemos calcular el ángulo interno (θ) como sigue:

\theta = (90 - 25.2)^{\circ} = 64.8 ^{\circ}

Ahora, el ancho del río es:

CO = tan(\alpha)*CA = tan(64.8)*28.2 = 59.9 m

Por lo tanto, el ancho del río es 59.9 metros.

Solve the following problem. Choose the correct answer.Sam's Discount Store offers a 2% discount for paying cash. How much would
Alex

Answer:

She would pay <u>$38.17</u>.

The correct answer is B.) 38.17

Step-by-step explanation:

Given:

Sam's Discount Store offers a 2% discount for paying cash.

A set of skillets priced at $38.95.

Now, to find the amount Joan would pay cash for a set of skillets.

Cost price of skillets = $38.95.

Discount rate = 2%.

Now, to get the price after discount:

38.95-2\%\ of\ 38.95\\\\=38.95-\frac{2}{100}\times 38.95\\\\=38.95-0.02\times 38.95\\\\=38.95-0.78\\\\=38.17.

Therefore, she would pay $38.17.

The correct answer is B.) 38.17
