Answer:

B

Step-by-step explanation:

GI is made up of the segments GH and HI. In other words:

GI=GH+HI

We know that GH is 2 and GI is 7. Substitute:

7=2+HI

Subtract 2 from both sides:

HI=5

So, our answer is B.

And we're done!

The problem is how many people must attend the third show so that the average attendance for three shows is 3000? And the other
Akimi4 [234]
An average is just the total attendance numbers / the number of performances.

Let's let the number of people in the third show be equal to x so we can write this as a formula, it's easier to read. x is just "some number we don't know"

The average is

Average=Total attendance/3
So
3000=(2580+2920+x)/3

So let's multiply by that 3 on both sides, make x easier to find

Average*3=2580+2920+x ( * means multiplied)

The average is 3000

So

2580+2920+x=3000*3
2580+2920+x=9000
 

Then we subtract those other attendances to get x on its own.

x=9000-2580-2920
x=3500

SSSSS [86.1K]

Answer:

Efectivamente, si se suman los resultados de la tabla del 2 con los de la tabla del 5 se obtienen los resultados de la tabla del 7.

Step-by-step explanation:

Esto es así porque 7 puede formarse a través de diversas sumas (7+0, 6+1, 5+2 o 4+3). Por ende, en el caso de las tablas de multiplicaciones, decir, por ejemplo, 7 x 3, es igual a decir 5 x 3 + 2 x3, dado que 5 + 2 es igual a 7.

Entonces, siguiendo el ejemplo, dado que 7 x 3 es igual a 21, la suma de 5 x 3 igual a 15 y 2 x 3 igual a 6 es 21 (15 + 6), con lo cual la afirmación es correcta.

Answer:

Part A:

Median value for Brand X = 13

Median value for Brand Y = 16

Part B: Brand Y has a longer battery life

Step-by-step explanation:

Part A:

Median value is depicted on a box plot by the vertical line that divides the rectangular box. Therefore:

Median value for Brand X = 13

Median value for Brand Y = 16

Part B:

Brand Y has a higher median value (16) than Brand X (13).

This implies that brand Y has a battery life that last longer than brand X.
