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)
Answer:
If they want irregular fractions its
1= 14/4 . 2= 11/2 3= 14/8
4= 21/4 . 5= 27/6 . 6= 125/13
7= 61/9 . 8= 69/9 . 9= 84/8
If they just want the few simplified then
1= 3 1/2
3= 1 3/4
5= 4 1/2
8= 7 2/3
9= 10 1/2
Step-by-step explanation:
Amount of milk drunken: (4 children)(0.5 gall per week per child)

4(0.5)($2.89) = $5.78 per week milk expenditure
Are you sure you wrote the equation right? Because I got 5/3 which equals 1.6666...7
Answer:
x= 2
<XYW= 56
Step-by-step explanation:
6X+44+(-10X+65)=117
-4X+109=117
-109 -109
4X/4 =8/4
X= 2
6(2)+44
12+44= 56
<XYW= 56
