Answer:
20 centimeters
Step-by-step explanation:
Karina's aquarium can hold 80 liters,which is equal to 80,000cm³.The base measure 100cm by 40cm.What is the height of the aquarium in centimeters?Round your answer to the nearest hundredth.
The shape of an Aquarium = Rectangular Prism
Volume of the rectangular prism = L × Width × Height
Volume = 80 Liters = 80,000 cm³
Base = 100 cm × 40 cm
Height of the aquarium is calculated as:
80,000cm³ = 100 cm × 40 cm × h
h = 80,000cm³/100 cm × 40 cm ×
h = 20 cm
The height of the aquarium = 20cm
This means that the sample mean is not systematically smaller or larger than the population mean. Or put another way, if we were to repeatedly take lots and lots (actually an infinite number) of samples, the mean of the sample means would equal the population mean.
Answer:
y=-29.98
Step-by-step explanation:
y=2/3(6)^2-5(6)
y=2/108-30
y=1/54-30
54y=1-1620
y=-1619/54
y=-29.98
