n a rural area, only about 30% of the wells that are drilled find adequate water at a depth of 100 feet or less. A local man cla
enyata [817]

Answer: the man's claim is true.

Step-by-step explanation:

Given that 30% of the well find water at a depth <=100 feet

P(X<=100) = 0.30

If the man's prediction work well the probability of finding well at less than 100 or equal should be high fwhen calculated from his results. So give 27 out of 80 wells

P(X<=100) = 27/80

P(X<=100) = 0.3375

Since 0.3375 > 0.3

The man's claim is true.

Pre-cal help!! (See Attachment)
MAVERICK [17]
2cos(x) + 1 = 0

cos(x) = -\frac{1}{2}

The basic angle for 1/2 is 60°, and cosines are negative in the first and third quadrant.

So, you take 180° - 60° = 120° to get the angle in the first quadrant, and 180° + 60° = 240° to get the angle in the third quadrant.

Since only 120° is an option, the answer is B.

How do I simplify this?
ololo11 [35]
Don't get too involved in the 'simplify' part just yet.
It doesn't mean make the problem easier.
It means that when you have the answer, make sure it's in simplest form.
That's why it says "Simplify your answer".
Notice that that's the 2nd instruction.
There's nothing to simplify until you have an answer.

The first thing you have to do here is find the area of a triangle.
Do you remember that formula ? 
I'll bet you do.
The area of a triangle is            (1/2) · (length of the base) · (height)  .

The height and the length of the base are given, right there
in the picture.  Take those, and use them to find the area.

Once you've multiplied the binomials, don't forget about the (1/2).

Finally, you have a trinomial for an answer.
Put the big sweet cherry on top:  Factor it !
I think that's the 'simplify' part.

You may be surprised.
I was when I worked it out just now ... just for you.
