Answer:
x=3 , x=-3
Step-by-step explanation:
Add 9 on both sides
To remove base 'e' we take ln on both sides

Answer:
13 1/3 cups
Step-by-step explanation:
We assume flour is proportional to cookies, so we have ...
cups/dozens = x/10 = 4/3
Multiplying by 10 gives ...
x = 40/3 = 13 1/3
13 1/3 cups of flour are needed for 10 dozen cookies.
Answer:
9/10
30%
Step-by-step explanation:
Only in trial number 4, there is just one correct answer. In all other 9 trials at least 2 answers were correct. So the probability is 9 out of 10 trials give a winning outcome, in short, 9/10.
Giving birth to three males first, is true in 3 out of 10 trials. You can count the total numbers of Y's in the last column.
So 3/10 which is 0.3 which is the same as 30%.
