me 37.
Hope this helps

Answer: C is no and the others are yes.
Step-by-step explanation:
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.
We can tell it’s not a permutation because it’s picking two people. Order doesn’t matter.
The number of total possible groups of men is 9 C 2 = 9!/((9-2)!(2!)) = 36
The number of total possible groups of women is 11 C 2 = 11!/((11-2)!(2!)) = 55
55 * 36 = 1980 different groups in the committee
Answer:
d = 7
Step-by-step explanation:
Distance Formula: ![d = \sqrt{(x2 - x1)^2+(y2-y1)^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28x2%20-%20x1%29%5E2%2B%28y2-y1%29%5E2%7D)
Plug in our 2 coordinates:
![d = \sqrt{(2-2)^2+(1+6)^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%282-2%29%5E2%2B%281%2B6%29%5E2%7D)
And you should get 7 as your final answer.
