No change

Median for 10 numbers

12 , 14, 15 , 17 , 19 , 27, 29 ,37 , 45, 45

Median = 19+27/2 = 46/2 = 23

Answer:

Median

Step-by-step explanation:

I believe this is median, as the mode and median stay the same numbers with and without 26, Mean 26, Mode 45, so the median would change the most as it goes from 23 to 26

Answer:

s = 14

Step-by-step explanation:

Step 1: Combine like terms.

$(\frac{2}{3}s + \frac{5}{6}s) = 21$
$(\frac{4}{6}s + \frac{5}{6}s) = 21$
$\frac{9}{6}s = 21$
$\frac{3}{2}s=21$

Step 2: Multiply both sides by 2/3.

$\frac{3}{2}s * \frac{2}{3} = 21 * \frac{2}{3}$
$s = \frac{42}{3}$
$s = 14$

6 times the difference of a number and 4 equals 7

Nonamiya [84]

6( x - 4) = 7
6 x - 24 = 7
6 x = 7 + 24
6 x = 31
x = 31/6

6 ( 31/6 - 4) = 7
186/6 - 24 = 7
186/6 = 144/6 = 7

42/6 = 7
7 = 7

The ratio of doves to parrots in a cage is 1 to 2. If there are 6 doves and parrots altogether then how many parrots are there?

Mama L [17]

There would be 2 doves and 4 parrots.

2 + 4 = the 6 in total, and the ratio between doves (2) and parrots (4) is 1 to 2 because the ratio of 2 to 4 is equal to 1 to 2.
