Find the mean of the data. <br> 9, 16, 13, 14, 10, 16 , 17, 9 <br> Thanks! Will mark brainly!
saw5 [17]

Answer:

13

Step-by-step explanation:

The mean of the data is also known as the average. To find the mean/average, add up all the data and divide it by the number of inputs recorded.

9 + 16 + 13 + 14 + 10 + 16 + 17 + 9 = 104

There are 8 terms.

104 / 8 = 13

The mean is 13.

Hope this helps!

Samuel tiene 11 cajas con mosaico cuadrado de 20 cm por lado y quiere cubrir una pared que mide 3 cm y de largo 2 cm de alto.Si
kirza4 [7]

Answer: Samuel no necesita comprar mas cajas.

Step-by-step explanation:

Cada mosaico es un cuadrado de 20cm por lado.

Entonces el área de cada mosaico es:

A = 20cm*20cm = 400cm^2.

En una caja hay 14 mosaicos, entonces cada caja puede cubrir:

14*400cm^2 = 5,600cm^2.

Ahora, el problema dice que la pared mide 3cm por 2 cm.

En ese caso, con un solo mosaico cubrirías la pared, entonces supongo que esta mal escrito.

Las dimensiones de la pared serian 3 metros por 2 metros.

1 m = 100cm

Entonces la pared es 300cm por 200cm.

El área total de la pared seria:

300cm*200cm = 60,000cm^2.

Ahora, cada caja de mosaicos cubre 5,600 cm^2.

Entonces el numero de cajas necesarias para cubrir toda la pared es:

(60,000cm^2)/(5,600cm^2) = 10.7

Entonces se necesitan 10.7 cajas para cubrir esa pared, y Samuel tiene 11, entonces el no necesita comprar mas cajas.

Point K is located at (7,4) in the coordinate plane. Its image is created by the following rule:
Fynjy0 [20]

We are given coordinate of K point (7,4).

We need to find the new coordinate of K' point.

Given rule is K' = Ro 270°^(k).

That represents rotation of k 270 degree about the origin.

<em>The rule for rotation of 270 degree about the origin is as following:</em>

<em>(x, y) --------> (y, -x).</em>

Now, applying same rule on point (7,4).

(7,4)  -----------> (4,-7).

<h3>Therefore, the coordinates of k' is (4,-7).</h3><h3>Correct option is A. (4,-7).</h3>
