Answer:
5 out of 7.
Step-by-step explanation:
There are seven days in one week. They are asking what is the probability of the person chosen not being born in a Tuesday or Wednesday. There are five other days, so there are five other options.
I hope I helped you!
(c+8)(c-8)
3(2y+5)(2y-5)
There are no like terms so it's still ab^2-b

Answer:
the graph corresponds to function "D" ![f(x)=3\,(\frac{1}{5} )^x](https://tex.z-dn.net/?f=f%28x%29%3D3%5C%2C%28%5Cfrac%7B1%7D%7B5%7D%20%29%5Ex)
Step-by-step explanation:
Since the graph shown corresponds to an exponential "decay" (the function decreases as we move from left to right), the base of the exponent has to be a number smaller than 1 (one). So we examine the only two options that give such (options C and D which have fractions as the base - 1/3 and 1/5 respectively)
From there, we analyze which of the two functions satisfies the crossing of the y-axis at (0,3) which is clearly shown in the graph:
We study both:
function C at x = 0 gives:
![f(x)= 5\,(\frac{1}{3})^x\\f(0)=5\,(\frac{1}{3})^0 \\f(0)=5\,(1)\\f(0)=5](https://tex.z-dn.net/?f=f%28x%29%3D%205%5C%2C%28%5Cfrac%7B1%7D%7B3%7D%29%5Ex%5C%5Cf%280%29%3D5%5C%2C%28%5Cfrac%7B1%7D%7B3%7D%29%5E0%20%5C%5Cf%280%29%3D5%5C%2C%281%29%5C%5Cf%280%29%3D5)
while function D at x = 0 gives:
![f(x)= 3\,(\frac{1}{5})^x\\f(0)=3\,(\frac{1}{5})^0 \\f(0)=3\,(1)\\f(0)=3](https://tex.z-dn.net/?f=f%28x%29%3D%203%5C%2C%28%5Cfrac%7B1%7D%7B5%7D%29%5Ex%5C%5Cf%280%29%3D3%5C%2C%28%5Cfrac%7B1%7D%7B5%7D%29%5E0%20%5C%5Cf%280%29%3D3%5C%2C%281%29%5C%5Cf%280%29%3D3)
Therefore, the graph corresponds to function "D"
