Answer:
b
Step-by-step explanation:
Answer:
2 cm
10 cm
Step-by-step explanation:
14/7 = 2
This helps to find because area of rectangle = bh or base times height.
A = 1/2 bh
30 = 1/2 b 6
30 = 3b
b = 10
For any probability the formula is
![P_{desired}=\frac{desired}{total}](https://tex.z-dn.net/?f=P_%7Bdesired%7D%3D%5Cfrac%7Bdesired%7D%7Btotal%7D)
. In this case we have 4 desired outcomes (the odds, 1, 3 and 5, and also 6) out of 6 total sides, so our probability
![P_{oddor6} =\frac{odd or 6}{total sides}=\frac{4}{6} = \frac{2}{3}](https://tex.z-dn.net/?f=P_%7Boddor6%7D%20%3D%5Cfrac%7Bodd%20or%206%7D%7Btotal%20sides%7D%3D%5Cfrac%7B4%7D%7B6%7D%20%3D%20%5Cfrac%7B2%7D%7B3%7D)
.
Mutually exclusive means the events cant occur at the same time. In our case it is not possible to roll both a 6 and an odd number at the same time since 6 is even. Therefore the events ARE mutually exclusive.
Combine the two parts and C is the correct answer. <span />
The answer is choice D
-----------------------------------------
Explanation:
We can rule out choice B and choice C which are y = 2.4^x and y = 3.5^x respectively. Why can we eliminate these? Because they are growth functions (the bases are larger than 1). The graph shown is a decay function. It goes downhill as you read it from left to right.
The answer is either choice A or choice D
If we plug in x = -2 into the equations for A and D, we get
y = 0.65^x = 0.65^(-2) = 2.36686
y = 0.32^x = 0.32^(-2) = 9.765625
The result for choice D is much closer to what the graph is showing. The graph appears to have the point (-2,11) on the curve. So that's why choice D is the best answer.
Note: the graph is a bit small and its not entirely clear which points are on this graph other than (0,1). So this is a bit of educated guesswork.
