Answer:
The height of cuboid is 3 cm
Step-by-step explanation:
Total surface area of cuboid = 
Length of cuboid = 10 cm
Width of cuboid = 2 cm
Let the height be x
Total surface area of cuboid = 
Total surface area of this cuboid is 112 cm squared
Hence the height of cuboid is 3 cm
(8/9)^2 is 64/81. Exponent is 2. Hope this help
Step-by-step explanation:
Given:
x = 26214.47
s = 5969.25
n = 15
t = 2.046
The confidence interval is:
CI = x ± t (s / √n)
CI = 26214.47 ± 2.046 (5969.25 / √15)
CI = (23061.06, 29367.88)
Remember them is the best way to go.
draw the exact value triangles if you're unsure, but importantly, you just need to memorise these exact values.
