Answer:
b= -5
Step-by-step explanation:
-10(10+b)=5(3b+5)
Distribute
-100 -10b = 15b +25
Add 10b to each side
-100-10b+10b = 15b+10b +25
-100 = 25b+25
Subtract 25 from each side
-100-25 = 25b+25-25
-125 = 25b
Divide by 25
-125/25 =25b/25
-5 =b
Answer:
The probability of the number of Protestants that were calm for 2 out of 3 days is 0.061.
Step-by-step explanation:
Represent the provided data as follows:
Compute the probability of the number of Protestants that were calm for 2 out of 3 days as follows:

The number of Protestants surveyed is, <em>n</em> (Protestants) = 99.
The number of Protestants who were calm for 2 days,
<em>n</em> (Protestants who were calm for 2 days) = 6
The required probability is:

Thus, the probability of the number of Protestants that were calm for 2 out of 3 days is 0.061.
