The mean length of 10 childrens' index finger is 12.6cm.
ICE Princess25 [194]

Get total lengths by multiplying:

10 x 12.6 = 126

6 x 16.1 = 96.6

Add the total lengths together and divide by 16:

126 + 96.6 = 222.6


222.6 / 16 = 13.9125

Rounded to 2 decimal places = 13.91


answer: 13.91

Please help I don’t understand
marta [7]

Answer:

x = 5

Step-by-step explanation:

The 2 strokes through XM and MY indicate the segments are congruent, so

YM = MX , that is

8x - 24 = 3x + 1 ( subtract 3x from both sides )

5x - 24 = 1 ( add 24 to both sides )

5x = 25 ( divide both sides by 5 )

x = 5

PLSSSSS HELP ME
Nikitich [7]

yKpoI14uk [10]

Answer:

y = x - 3

<h3>How I know I'm correct:</h3>

if you plug in the numbers from the table, it checks out.

y = x - 3

0 = 3 - 3

0 = 0

y = x - 3

1 = 4 - 3

1 = 1

y = x - 3

2 = 5 - 3

2 = 2

and so on
