At 90% confidence level:
α = 0.10
α/2 = 0.05
At 22 degrees of freedom:
χ²L = 12.338
Answer:
im think its B
Step-by-step explanation:
By similar triangles...
p/37=33/83
p=37(33)/83
p=1221/83 m
p≈14.711 m (to nearest thousandth of a meter, or nearest millimeter)
30.... you set them all equal to 180... 2x+10+2x+25+x-5= 80. You then simplify to 5x+30=180. Subtract 30 from 180 and you get 5x=150 then divide 150 by 5 and you get 30.
