Have of u is less than equal to 43
1 answer:
The question is incomplete. The complete question is here;
Half of u is less than or equal 43, find the greatest possible value of u
The greatest possible value of u is 86
Step-by-step explanation:
To solve an inequality:
- Write the inequality
- Separate the variable in one side and the numerical term in the other side
- Divide both side by the coefficient of the variable, remember if the coefficient is negative reverse the sign of the inequality
- The solution of the inequality is all possible values of the variable
∵ u ≤ 43
- Divide both sides by
∴ u ≤ 86
- That means u could be any numbers less than or equal 86
∵ You need the greatest possible value of u
∴ u = 86
The greatest possible value of u is 86

<h3>Given information-</h3>The mean for the bulb is 12,000 hours.
The standard deviation for the bulb is 2000 hours.
Sample value is 14500.
To find out the how many standard deviation is 14500 mean away from the mean the z value of the mean should be calculated.
<h3>Z value</h3>Z value is a numerical measurement that describe a value relationship to the mean of a group of values. Z value is the ratio of the difference of the sample value and mean
to the standard deviation. Thus the z value for the given mean
is,
