Answer:
it has been found that 85.6% of all enrolled college and university students in the U.S. are undergraduates. A random sample of 500 enrolled college students in a particular state revealed that 420 of them were undergraduates. Is there sufficient evidence to conclude that the population differs from the national percentages? Use a = 0.05
25 out of 33 passed the test.
Lets see how many failed,
33-25 = 8
Now lets take out the percentage which basically will be
8÷33×100= 24.4%
Answer: 11/-10
Why?
Difference of y / difference of x
12-1 / -19+9= 11/-10
So the slope is 11/-10
Answer:
Looking at the given points we know that it is going to be a triangle because it only have 3 points. Therefore the figure is a triangle and the area formula would be
.
You can look at the attached graph and what we see is that our height of the triangle is from
to
which means that our height is 7 units high. We can also see that our base starts at
and ends at
making us have a base of 8 units.
<u>We then plug in the values and solve</u>



Therefore, the area of our triangle is

Answer:
-303.11 -175
Step-by-step explanation:
The jet has a speed of magnitude 350 miles/hour and travelling in a direction of 210°. Hence the jet can be represented with |r| = 350, θ = 210°.
The component form of the vector has both the x component (horizontal component) and the y component (vertical component) Therefore:
The horizontal component = 
The vertical component =
