Answer: 1145 feets
Step-by-step explanation:
The total feet of streamer that Shirley have to decorate with will be the addition of the total roll of blue streamer plus the total roll of green streamer. This will be:
= 5(93) + 8(85)
= 465 feet + 680 feet
= 1145 feets of streamer.
is 93 feet long and each roll of
Answer:
The volume is 192.96
Step-by-step explanation:
You multiply length x width x height to find the volume.
75x + 90(15-x)=88(15)
75x+1350-90x = 1320
-15x + 1350 = 1320
-15x= -30
x=2
the amount of 75 octane is 2 gallons
the amount of 90 octane is 13 gallons
Hope this helps.
Given:
difference in the mean weight gain is 0.60 grams
standard deviation of the difference in sample mean is 0.305
68% confidence interval for the population mean difference is a) 0.305
0.60 <u>+</u> 1 * 0.305
0.60 + 0.305 = 0.905
0.60 - 0.305 = 0.295
95% confidence interval for the population mean difference is c) 0.61
0.60 <u>+</u> 2 * 0.305
0.60 + 0.61 = 1.21
0.60 - 0.61 = -0.01
