Answer:

20% chance.

Step-by-step explanation:

If you do not know the formula, here is a quick intuitive method.

Construct the sample space in a square with 4 divisions

split one side into 1/2 and 1/2 and the other side into

.4 and .6

You can easily see that the day that it will rain on both days is .2 (1/2*.4)

or 20%

Write whether the scenario represents a linear function or an exponential function? Explain why.
Ad libitum [116K]
The scenario represents a linear function. The rate is at a constant increase therefore it is linear.

Linear because it’s a constant rate

Since it’s doubled, and doesn’t go at a constant rate, it is a exponential function

Exponential since it increases by a multiplicative rate. It’s not constant

Can anyone please help me :)
Solnce55 [7]

Answer:

5 to the 15th power.

Step-by-step explanation:

PEMDAS requires us to do parenthesis, then exponents, and then division. Let's do 5³. 5x5x5 is equal to 125. Now, we find 125 to the ninth power. According to my calculations, 125 to the ninth power is equal to 7,450,580,596,923,828,125. Now, we find 5 to the twelfth power, which, according to my calculations, is 244,140,625. Now, we solve. According to my calculations, 7,450,580,596,923,828,125/244,140,625 is equal to 30,517,578,125. 30,517,578,125 is equivalent to 5 to the 15th power. That means that the second option is correct. I hope this helps!
