Answer:
x=7,y=5
C. x = 7, y = 5
Step-by-step explanation:
x = 12-y
2x+ 3y = 29
substitute x= 12-y
2 (12-y) + 3y = 29
distribute
24 - 2y + 3y = 29
combine like terms
24 + y = 29
subtract 24 from each side
24-24 +y = 29-24
y = 5
now find x
x=12-y
x = 12-5
x=7
(7,5)
Answer:
Stop the line of production since the sample mean (56.96) is outside the confidence interval [ = ( 56.98, 57.05 )]
Step-by-step explanation:
Given that;
95% confidence interval for these parts is 56.98 to 57.05
= ( 56.98, 57.05 )
Sample mean = 56.96
We know that;
If the sample mean is within the confidence interval then, our decision is to keep the line operating as it is inside the confidence interval.
But if the sample mean is not within the confidence interval them, our decision is to stop the line of production as it is outside the confidence interval.
Now since our mean sample (56.96) does not lie between with the 95% confidence interval = ( 56.98, 57.05 ).
Therefore, Stop the line of production since the sample mean (56.96) is outside the confidence interval [ = ( 56.98, 57.05 )]
The answer is D 6^4
6 would be 6^1
6x6 would be 6^2 etc
Put the numbers in order from smallest to largest:
21,34,45,53,71,88
Since there are an even amount of numbers you must take the middle two and find the average(add them together then divide by 2)
45+53=98
98/2=49
I think the answer above is correct
