Answer:
1/15
Step-by-step explanation:
There are a total of 10 fruits, 3 of which are apples.
The probability that the first selection is an apple is 3/10.
There are now 9 fruits remaining, 2 of which are apples. So the probability that the second fruit is an apple is 2/9.
The total probability is (3/10) (2/9) = 1/15.
We want to determine the domain of
![{y=3 \cdot 2^{-x}=3 \cdot ({2^{-1}})^x=3 \cdot ({ \frac{1}{2}})^x](https://tex.z-dn.net/?f=%7By%3D3%20%5Ccdot%202%5E%7B-x%7D%3D3%20%5Ccdot%20%28%7B2%5E%7B-1%7D%7D%29%5Ex%3D3%20%5Ccdot%20%28%7B%20%5Cfrac%7B1%7D%7B2%7D%7D%29%5Ex)
any function of the form
![y=f(x)=a \cdot b^x](https://tex.z-dn.net/?f=y%3Df%28x%29%3Da%20%5Ccdot%20b%5Ex)
is called an "exponential function",
the only condition is that b is positive and different from 1, and a is a nonzero real number.
The domain of such functions is all real numbers.
That is for any x, the expression <span>3(2^-x) "makes sense".
Answer: </span><span>The domain is all real numbers</span>
Answer: 22/21
Step-by-step explanation:
2 cakes : 7 donuts → 6 cakes : 21 donuts
3 cakes : 11 brownies → 6 cakes : 22 brownies
22 brownies : 21 donuts
Now, simply write this as a fraction. 22/21
