Answer:

D. 9

Step-by-step explanation:

When you add 1 + 4 + 5 + 5 + 5 + 6 + 9 + 10 + 10 + 11 + 12 + 12 + 15 + 15 + 15 = 135. Which is all of the numbers given to you, and since mean is when you add all of the numbers together, and than divide it by the amount of numbers there, you will take that 135 and divide it by 15. 135 / 15 = 9. Which gets you to finally getting an answer of 9. so D. 9 is correct.

What is the measure of y? 3 27 y Z * A y = [?] Give your answer in simplest form.​
Andrews [41]

Applying the geometric theorem, the measure of y = 9.

<h3>What is the Geometric Theorem?</h3>

The geometric theorem states that, h = √(ab), where h is the altitude of a right triangle, a nd b are the segments formed when the altitude divides the hypotenuse of a right triangle.

Thus:

y = altitude = ?

a = 3

b = 27

Substitute

y = √(3 × 27)

y = √81

y = 9

Therefore, applying the geometric theorem, the measure of y = 9.

Lucía pagó $539.50 por una playera que costaba $650. ¿Qué porcentaje le hicieron de descuento?
Aneli [31]

Answer:

17%

Step-by-step explanation:

Lucía pagó 539.5 en lugar de 650 (el original) Entonces el descuento fue 650-539.5=110.5

Ahora, nosotros necesitamos buscar qué porcentaje de el original fue el descuento:

(porcentaje)% de 650 = 110.5

(porcentaje)/100 * 650 = 110.5

(porcentaje) = 110.5*100/650 = 11050/650 = 1105/65 = 17

El descuento fue: 17%
