Answer:

a) 21

b) 21

Step-by-step explanation:

Given 10 scores: 19, 15, 34, 29, 13, 35, 10, 19, 14, 22

a) Mean

= (sum of scores) / number of scores

= (19+15+ 34+ 29+ 13+ 35+ 10+ 19+ 14+ 22) / 10

= 210 / 10

= 21

b) one more score of 21 is added

hence

number of scores = 10 + 1 = 11

sum of scores = 210 + 21 = 231

Mean = (sum of scores) / number of scores

= 231 / 11

= 21

Find the perimeter of the triangle defined by the coordinates (9, 0), (-5, 0), and (-10, 6). (Round to nearest tenth)

Masteriza [31]

The perimeter is 41.7

Find the length of each side using the distance formula:
$d=\sqrt{(0-0)^2+(-5-9)^2}=\sqrt{0^2+14^2}=\sqrt{196}=14
\\
\\d=\sqrt{(6-0)^2+(-10--5)^2}=\sqrt{6^2+(-5)^2}=\sqrt{36+25}=\sqrt{61}=7.8
\\
\\d=\sqrt{(6-0)^2+(-10-9)^2}=\sqrt{6^2+(-19)^2}=\sqrt{36+361}=\sqrt{397}=
\\19.9$

Adding the side lengths, we have
14+7.8+19.9=41.7
