Answer:
7/15
Step-by-step explanation:
To find the probability the student is a senior
P( senior) = number of seniors / total students
= 14 / ( 14+7+4+5)
= 14/30
= 7/15
Answer:
Step-by-step explanation:
x/regular price=y
1-y=discountx100
So, say you get a pair of shoes that are normally $100 and you pay 75. 75/100=.75. 1-.75=.25x100=25. This means you got a 25% discount.
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.
Note that one side is 20 ft, and the other is 16.
This means that the side that is part of the triangle is 4 ft.
The measurement is still the same for the triangle's height.
Find the area of the rectangle:
24 x 16 = 384
Find the area of the triangle:
4 x 24 = 96
Add the two numbers together:
384 + 96 = 480
You're answer is (C)
