Answer:
0.343
Step-by-step explanation:
First, find the different ways one can chose a professor or instructor. In this case, there are 8 professors and 4 instructors. So there are a total of 12 ways you can choose a professor or instructor.
Second, you want to find the different ways you can choose any member of the faculty. In this example, since you are only choosing one person, then you just find the total number of people in the faculty, which is 8 + 11 + 12 + 4 = 35.
Third, all you do is divide the different ways you can get a professor or instructor by the total different ways you can choose. So it's 12/35, or 0.343.
Answer:
34 square units
Step-by-step explanation:
The figure can be considered to be a trapezoid with a rectangle removed.
The area of the trapezoid is ...
A = (1/2)(b1 +b2)h
A = (1/2)(10 +6)(5) = 40
The area of the rectangle is ...
A = LW
A = (3)(2) = 6
Then the area of the shaded portion of the figure is ...
shaded area = trapezoid area - rectangle area
= 40 - 6 = 34 . . . square units
So, let's add up the total amount he made:
120 + 80 + 75 = 275
If he withdrew $30:
275 - 30 = 245
Tom will have $245 at the end of June
Divide both values.
12/4 = 3
3 is how much stunts per movie.
Answer: 3 stunts in one movie
The colony doubles every hour, the population is equal to
p = 2^t
<span>Where t </span><span>is the time in hours.</span>
We are able to see this because:
2^0 = 1
2^1 = 2
2^2 = 4
Notice that the x coordinate of the graph corresponds to the time, and the y coordinate corresponds to the population.
<span>Thus at t = 9
</span>p = 2^t
p = 2^9
p = 512.
The correct answer is 512.
