Answer:
3 bulbs should be flawed
Step-by-step explanation:
2+ 18 = 20
20 bulbs were examined
2/20 = 1/10 were flawed
looking at the next 30 bulbs
30 * 1/10 = 3
3 of the next 30 bulbs should be flawed
Answer:
(x, y) (1,5.5) , (2,5.75) (3,5.83) (4,5.875) (5,5.9)
Step-by-step explanation:
The x values lie on the horizontal line and the y values lie on the vertical line.
In order to find the value of y you must substitute the value of x in the equation given and you must plot you graph using the answers you got which I wrote for you.
NOTE:if there's anything you don't understand let me know.
Answer:
y = 3/5x + 3/5.
Step-by-step explanation:
the /'s are division symbols. 3 3
y = _ + _
5 5
Answer:
Money which Michael make in commission = 158.7
Step-by-step explanation:
Given that,
number of hours Michael worked in a week = 40 hours
total sale of the week = 2870
commission which Micheal will get on sale = 6% above 225sale
To find,
total money Michael make in commission in the week
Commission = (2870 - 225)*6%
Commission = (2870 - 225)*6/100
Commission = 2645 *6/100
Commission = 158.7
Total money Micheal make in a week = (40*12.50) + (158.7)
= 658.7
With amounts measured in gallons, let
x = amount of 65% antifreeze
y = amount of 90% antifreeze
1 gal of the 65% brand contains 0.65 gal of pure antifreeze; x gal would contain 0.65x gal. Similarly, y gal of the 90% brand contains 0.90y gal of pure antifreeze.
To obtain 120 gal of 80% antifreeze solution (which contains 0.80•120 = 96 gal of pure antifreeze), we must have
x + y = 120 … … … … … [total volume of antifreeze solution]
0.65x + 0.90y = 96 … [total volume of pure antifreeze]
Solve the first equation for y :
y = 120 - x
Substitute this into the second equation and solve for x :
0.65x + 0.90 (120 - x) = 96
0.65x + 108 - 0.90x = 96
0.25x = 12
x = 48
Solve for y :
y = 120 - 48
y = 72
