Answer:
70
Step-by-step explanation:
Part A: After 9 days the radius of algae was approximately 12.81 mm. The reasonable domain to point is (0,9).
Part B: The 9 on the y-intercept represents the amount of algae the experiment started with.
Part C: (12.81-10.12)/7=0.38
g(a)=33a−2; Find g(1)
g(1) means the value of a is 1. Replace a in the equation with 1 and solve.
33(1) - 2 = 33-2 = 31
g(1) = 31
Answer:
a) If a key is selected at random, what is the probability that the key for channel 1 is pressed?
1/10
<em>There are 10 channels in total. 9 channels + 0 channel. </em>
<em />
b) If a key is selected at random, what is the probability that the key for an even number is pressed?
5/10
0,2, 4, 6, 8 < The even numbers out of 10 channels
c) If a key is selected at random, what is the probability that the key for a number more than 6 is pressed?
3/10
<em>7, 8, 9 are the numbers greater than 6</em>
