Answer:
B) 1/2 ml
Step-by-step explanation:
The computation of the number of liquid in each breaker is shown below:
Here we start by including the amount that is mentioned in the plot line
We start by adding the amounts given by the line plot:
Now determined the common denominator
here the smallest thing is 2,4 and 8 and i.e. evenly divided by 8
Find a common denominator. The smallest thing that 2, 4 and 8 will all evenly divide into is 8:
Now add the numerators
After this, divide it by 9
Answer:
The 95% confidence interval estimate for the population mean life of compact fluorescent light bulbs in this shipment is between 7,255 hours and 7,745 hours.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 7500 - 245 = 7255 hours.
The upper end of the interval is the sample mean added to M. So it is 7500 + 245 = 7745 hours.
The 95% confidence interval estimate for the population mean life of compact fluorescent light bulbs in this shipment is between 7,255 hours and 7,745 hours.
Answer: 140 miles
let me know if this is wrong
Step-by-step explanation:
135-30=105
105÷0.75=140
Answer:
B. {x| x > 2 or x < -4}
<em></em>
Step-by-step explanation:
Given
Required
Solve
Start by dividing both sides by 5
Find critical point of the inequality by changing the inequality to equality
Split the above expression
Make x the subject of formula in both
Check the intervals in between the critical points
Set: --- This works in the inequality
Set: --- This doesn't work in the inequality
Set: --- This doesn't works in the inequality
Set: --- This works in the inequality
<em>Hence, the solution is: {x| x > 2 or x < -4}</em>
