Question #1:
b + 0.6 = -1
b + 0.6 - 0.6 = -1 - 0.6
b = -1.6
Answer:

---------------------------------------------------
Question #2:
y - 0.6 = -1.8
y + (-0.6) + 0.6 = 1.8 + 0.6
y = -1.2
Answer:

---------------------------------------------------
Question #3:
n + 11.5 = -29
n + 11.5 - 11.5 = -29 - 11.5
n = -40.5
Answer:

---------------------------------------------------
Question #4:
e - 14.4 = -20.8
e - 14.4 + 14.4 = -20.8 + 14.4
e = -6.4

Hope This Helped! Good Luck!
Based on the relative frequency and the number of times the experiment is to be performed, the number of times Event A should occur is 10 times.
<h3>How many times should Event A occur?</h3>
The relative frequency in this regard is 1/3.
The number of times it will occur can be found as:
= Relative frequency x Number of times event was performed
Solving gives:
= 1/ 3 x 30
= 10 times

The answer is 20!
you need to change the subtraction sign to an addition sign and change -4 to a 4. then, solve!
hope this helps!!
