Answer:
The distance from A to B is 736.2 to the nearest tenth foot
Step-by-step explanation:
In ΔCAB
∵ m∠CAD = 30° ⇒ exterior angle of Δ at vertex A
∴ m∠CAD = m∠ACB + m∠ABC
∵ m∠ABC = 20°
∴ m∠ACB = 30° - 20° = 10°
We will use the sin rule to find the distance AB
∵ 
∴
≅ 736.2 to the nearest tenth foot
Answer:
Variance is the squared deviation and deviation is the difference of observed value from other values
Step-by-step explanation:
Variance is the squared deviation and deviation is the difference of observed value from other values


Where, 
Answer:
0.3 or 3/10
Step-by-step explanation:
100%=1 so 30%=0.3
Answer: 56
Step-by-step explanation: 7*480= 3360
3360/60= 56
Your answer is B) -5/6.
We can find this using the formula (y2 - y1)/(x2 - x1) and substitute in the coordinates:
(-2 - 3)/(5 - -1) = -5/6
I hope this helps!
