Answer:
1/3 ! i think?
Step-by-step explanation:
there's a 1/2 chance it lands on heads and a 2/3 chance it lands on red or blue and 1/2 x 2/3 is 1/3
It can't be A, B, nor C because some of the equations wouldn't have a straight line if displayed in a graph. For example A has a square root symbol and b and a have an exponent they would create a perebula where that would mean the equations would not make a straight line. However, Choice d doesn't have any exponents, or square root symbols meaning the equation could slope up or down in a STRAIGHT line in a graph.

Step-by-step explanation:</h2>
A function has an inverse function if and only if passes the Horizontal Line Test for Inverse Functions. This test tells us that a function 
has an inverse function if and only if there is no any horizontal line that intersects the graph of at more than one point. So the function is called one-to-one. The graph of 
is shown below. As you can see, this function does not pass the Horizontal Line Test, therefore the inverse is not a function. However, let's find 
:
Finally, substitute

Answer:
0.785 m
Step-by-step explanation:
(4-2x)(6-2x)x = Volume
Volume = 4x³ - 20x² + 24x
Max volume: dV/dx = 0
dV/dx = 12x² - 40x + 24 = 0
3x² - 8x + 6 = 0
x = 2.54858377, 0.784749563
Max when d²V/dx² < 0
d²V/dx² = 6x - 8
At x = 0.784749563
6x - 8 = -3.29 < 0
Answer:
A: H0: p = 0.27; Ha: p > 0.27
Step-by-step explanation:
The parameter is the population proportion.
According to the survey conducted by the American Academy of Periodontology, the proportion of of US adults who admit they lie to their dentist about how often they floss their teeth is 27%.
This means the null hypothesis is :
Periodontist Dr. Garcia believes that the percentage seems low, so his claim is that the percentage should be more than 27%.
This means, the alternate hypothesis is
Therefore the correct choice is A.
