3 pairs=6 earrings
P=(a+2b)6
a=2cm
50/6=2+2b
8.33-2=2b

find the mean, median, and mode of the data set. round to the nearest tenth. 7,7,14,15,4,1,7,2,15,9,5
Arisa [49]
Here is the mean, median, and mode:
Mean: 1+2+4+5+7+7+7+9+14+15+15 = 86/11 ≈ 7.82
Median: 7
Mode: 7
To find the mean add up all the numbers and divide by the number of numbers
To find the median you just keep on crossing of numbers left to right until you get the middle number
To find the mode just look at which number is most commonly seen
Hope this helps!
Answer: 441
Step-by-step explanation:
21 x 21 = 441
-1/2( 3x -4) = 11
Use distributive properties:
-3/2 + 2,= 11
Subtract 2 from both sides:
-3/2x = 9
Divide both sides by -3/2
X = 9/ -3/2
X = -6
The answer is c. -6
