Answer:
x= -1
Step-by-step explanation:
since y is -5 then we would put that in the second equation:
2x - 4(-5) = 18
then it’s:
2x + 20 = 18
Then we subtract 20 from both sides
2x = -2
Last we divide both by 2 and we get x = -1
ANSWER:
Distance between two points W and E = 146 miles and B is the position of B (balloon)
Angle BWE =55 degrees and angle BEW =67 degrees therefore angle WBE = 180-55-67 =58 degrees
Using sine formula
w/sin (55)= b/sin(58)
w= 146{sin 55/ sin 58) =141 miles Step-by-step explanation:
Answer:
The correct answer choice would be:

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 )]
Answer:
A=300
Step-by-step explanation:
995-165=830
830+795=1625
1625-1200=425
425-125=300
