Answer: A confidence interval for the mean cost (in dollars) for one shipment of vases = (49,59)
Step-by-step explanation:
Confidence interval for mean: Mean ± Margin of error
Given: The online store found the mean wholesale cost of one shipment of vases was ĉ = 54 dollars, with a margin of error of 5 dollars.
A confidence interval for the mean cost (in dollars) for one shipment of vases

Hence, a confidence interval for the mean cost (in dollars) for one shipment of vases = (49,59)
<span> l =PRT
so
T = I/(PR)

-7x+14>-3x-6
Add 3x to both sides
-7x+14+3x>-3x-6+3x
-4x+14>-6
Subtract 14 from both sides
-4x+14-14>-6-14
-4x>-20
Divide both sides by -4
-4x/4>-20/-4
x<5
I hope that's help , please let me know !
Answer:
x=7
y=-1
Step-by-step explanation:
When the two equations are solved together, they form simultaneous equations.
x+y=6
x-y=8
Let us use the elimination method. if we add the two equations, we eliminate y.
2x=14
x=7
Let us substitute for the value of x obtained above.
x-y=8
7-y=8
y=7-8
y=-1
