Answer:
(- 5, 2 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( , )
Here (x₁, y₁ ) = A(- 8, - 6) and (x₂, y₂ ) = B(- 2, 10) , thus
midpoint = ( , ) = ( , ) = (- 5, 2 )
Gallons of water are leaked in one year is 94.253 gallons
<h3><u><em>
Solution:</em></u></h3>
Given that leaky faucet drips 356,755 mL of water over the course of the year
There are approximately 3,785 mL in 1 gallon.
To find: gallons of water are leaked in one year
From given information,
Amount of water leaked in one year in ml = 356,755 mL
Also given in question that,
<h3>
1 gallon = 3785 ml</h3>
<em><u>Now we can convert 356,755 mL to gallons</u></em>
Thus gallons of water are leaked in one year is 94.253 gallons
Answer:
602.50 hours
Step-by-step explanation:
Given that a manufacturing plant uses light bulbs whose life spans are normally distributed, with mean and standard deviation equal to 500 and 50 hours,
It was decided to replace the bulbs so that no more than 2% of the bulbs to burn out between replacement periods
i.e. we have to construct 98% confidence interval right tailed to get this.
Z value is 2.05 for this (Upper tailed 0.98 probability)
Hence margin of error
The upper bound for this would be
So to keep below 2% the bulbs to burn out it should be replaced before 602.50 hours.
