Let X be the accelerated life test on a large number of type-D alkaline batteries revealed that the mean life for a particular use before they failed
X is NOrmal with mean =19, sigma = 1.2
For 95% critical value = ±1.96
Margin of error = ±1.96*1.2
=±2.352
Confidence interval 95% = Mean ±2.352
=(16.648, 21.352)
Answer:
x =
Step-by-step explanation:
In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away 17 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.
- 2x + 4 = -6x - 17
→ Add - 6x to both sides to bring all the 'x' coefficients to one side
4x + 4 = -17
→ Minus 4 from both sides to bring all the integers to the other side
4x = -21
→ Divide both sides by 4 to isolate x
x =
