Answer:
x = ln 10
Step-by-step explanation:
You meant e^x - 1 = 9. Let's isolate e^x, by adding 1 to both sides. We get:
e^x = 10
Now make use of the property ln a = b <=> a = e^b
Then e^x = 10 becomes
x = ln 10
Answer:
0.02 or 2%
Step-by-step explanation:
Theoretical probability calculated by dividing the number of events you want to calculate(green marble) with the total event possible(red + blue + green). There are 4 red marbles, 5 blue marbles, and 1 green marble. The probability will be: 1/(4+5+1)= 1/10= 10%
The result of the experiment is:
Red=22
Blue= 24
Green=4
Experimental probability calculated by dividing the number of events occurs with the total number of trials. We pull green 4 times and do 50x pulls, so the probability is: 4/50= 8%
Difference between the theoretical probability and the experimental probability is: 10%- 8%= 2%
Answer:

Step-by-step explanation:
Answer:
12
Step-by-step explanation:
-48/(-4)
= -1/(-1) * (48/4)
= 1 * 12
= 12
The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate.
