Answer:
32.14
Step-by-step explanation:
it is a right triangle
so Pythagorean Theory is a^2 + b^2 = c^2
a and b are the legs of the right triangle
c is the hypotenuse
15.3^2 + b^2 = 35.6^2
234.09 + b^2 = 1267.36
1267.36 - 234.09 = 1033.27
1033.27 ^1/2 (square root) = 32.14

Answer:
70
Step-by-step explanation:
all the angles of a triangle sum 180, so 180 - (70 + 40) = 70
A is the weight
B is the frequency
C is weight times frequency
D is mean minus weight
E is D raised to the 2nd power ; variance
F is E times frequency ; total variance
A B C D E F
65 1 65 7.97 63.47 63.47
68 2 136 4.97 24.70 49.40
69 5 345 3.97 15.76 78.80
70 8 560 2.97 8.82 70.57
71 7 497 1.97 3.88 27.17
72 3 216 0.97 0.94 2.82
90 2 180 17.03 290.02 580.04
95 <u> 2 </u> <u> 190 </u> 22.03 485.32 <u> 970.64</u>
30 2,189 1,842.91
2,189 / 30 = 72.97 mean
1,842.91 / 30 = 61.43 variance
√61.43 = 7.8377 or 7.84 standard deviation.
