different between A and B
=30-(-30)
=60
position of C from A or B
=(60÷3)×2
=40
possible value of c
=-30+40
=10
possible value of c
=30-40
=-10
We let y equal to the elevation above sea level so that the elevation of the rock climber after x minutes of climbing would be:
y = 2x + 50
His initial height can be calculated when x is equal to zero it is when the climber is not yet climbing. Therefore, the rock climber'sinitial height above sea level would be 50 meters.
Step-by-step explanation:
There is 10 questions which in this case are the trials.
We know we can either get a question right or wrong so the two outcomes are right or wrong.
The probability that a student choose the right outcome is 1/4. since there is one right answer out of 4 chocies.choices.
Yes, the trials likelihood outcome of each outcome is the same. so it's independent
Answer:
Line CDE is a straight line,
so 85°+70°=55°
180°-55°=25°
angle BDA=25°
25°+85°=110°
180°-110°=70°
angle CDF=70°
Answer:
A
Step-by-step explanation:
16x-16=4y
4(4x-4)=4y
y=4x-4
Therefore, the correct answer is choice A. Hope this helps!
