Answer:
b = 17
Step-by-step explanation:
Pulling out like terms :
1.1 Pull out like factors :
425 - 25b = -25 • (b - 17)
Equation at the end of step 1 :
Equations which are never true :
2.1 Solve : -25 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
2.2 Solve : b-17 = 0
Add 17 to both sides of the equation :
b = 17
One solution was found :
b = 17

Answer:
D. There is no association because the distribution of lunch preference is approximately the same among the pet groups.
Do you remember your unit circle? If sin ω = was -1/2, then it would be 7<span>π/6. If you're unfamiliar with the unit circle, we can derive it.
So, you know that sin is OPPOSITE/HYPOTENUSE, and it's in the third quadrant, where x and y would be negative. If sin </span>ω = -1/2, that means that ω = 1/sin*(-1/2), or sin^(-1)*(-1/2). Let's ignore the negative for now and plug sin^(-1)*(-1/2) into your calculator in radians. You get (1/6)π. But that's in Quadrant 1. We want it in Quadrant 3.
In one complete revolution, or 360°, there are 2π radians. That means, if you want to rotate it 180°, you need to add π to what you originally got.
π+(1/6)π=(7/6)π.
I highly recommend you memorize the unit circle if you haven't already, because you'll need it from Precalculus on.
