I gotchu! there is no association shown between the two in this sample because the given information only shows the correlation between fur color and environmental and NOT gender.
hope you do amazing have a wonderful night
BD is 31 degrees because it is the same.
ADB is 90-31 because it is a right angle ( 59 degrees)
DEC is 180 - (31*2) because the 180 is of the trangle and the 31 is the same on the other side so times 2 then removed from 180
The answer is 157kJ
formula: q=mcT
q= 75 g x 4.18 J/goC x 50 oC
q= 157 kJ
Step 1. Combine like terms
Step 2. Subtract 7 from both sides
Step 3. Divide 6 from both sides
Final answer: x=1/6
The answer would be 30.
60/2 = 30
90/2 = 45
120/2 = 60
