Answer: 18%
There are 1879 people who are in the "graduate" row and "receiving aid" column. This is out of 10730 people total (bottom right corner)
The probability is 1879/10730 = 0.175 approximately which converts to 17.5% which rounds to 18%
Answer: 137
Step-by-step explanation: 11^2−5+(4)(7)/4(3)
121−5+(4)(7)/4(3)
116+(4)(7)/4(3)
116+(28/4)(3)
116+(7)(3)
116+21

Answer:
About 1.85 seconds and 13.15 seconds.
Step-by-step explanation:
The height (in feet) of the rocket <em>t</em> seconds after launch is given by the equation:

And we want to determine how many seconds after launch will be rocket be 390 feet above the ground.
Thus, let <em>h</em> = 390 and solve for <em>t: </em>
<em />
<em />
Isolate:

Simplify:

We can use the quadratic formula:

In this case, <em>a</em> = 8, <em>b</em> = -120, and <em>c</em> = 195. Hence:

Evaluate:

Simplify:

Thus, our two solutions are:

Hence, the rocket will be 390 feet above the ground after about 1.85 seconds and again after about 13.15 seconds.
Answer:
x = 100°
y = 125°
z = 55°
Step-by-step explanation:
A straight line is 180°
A triangle is 180°
Solve in this order:
X: 180 - 80 = 100
Z: 180 - 80 - 45 = 55
Y: 180 - 55 = 125
