Please take just a few seconds longer and write "inverse cosine" as either:
arccos x or
-1
cos x or
cos ^(-1) x
A is true, since for any given x in [0, pi], there is exactly one associated y-value.
C is false. For one input (x) value, there is more than 1 associated y-value.
The probability is 0.246 or 24.6%.
We can use a binomial distribution for this:
Answer:
24 rolls
Step-by-step explanation:
12 rolls x rolls
------------ = ------------------
4 dollars 8 dollars
Using cross products
12*8 = 4x
96 = 4x
Divide by 4
96/4 = 4x/4
24 =x
24 rolls
Answer:
The graph that corresponds to the function is B.
Step-by-step explanation:
Answer:
X = 9/2 or X = 3
Step-by-step explanation:
5x + 2 = 7x -7
5x - 7x = - 2 - 7
<u>2</u><u>x</u> =<u> </u><u>-</u><u>9</u>
2 2
X = - 9/2
or X = 3 (lowest term)
