Answer:
About 400 times
Step-by-step explanation:
Given
See attachment for spinner
Required
Determine the number of times an outcome of 1, 3 or 8 is expected
First, calculate the theoretical probability of 1, 3, or 8
This is calculated as:
The spinner is divided into 8 equal segments and each outcome appears once.
So, we have:
Take LCM and add
So, the expected number of times (E) is:
Approximate
<em>This means about 400 times</em>
2 ↔ exponent
5 ↔ coefficient
7 ↔ constant
x ↔ variable

is the correct answer
Answer:
The second possible answer is the correct one.
Step-by-step explanation:
The second possible answer is the correct one. As x increases, 4^x increases exponentially. However, in this case there's a negative sign in front of 4^x, so we know that the graph follows an exponential trajectory downward. Also note that 4^0 = 1, so 1 - 4^x = 0 at x = 0.
