Answer:
28 x 28 x 28 = 21,952 cm³
Step-by-step explanation:
<span>Density is a mathematical expression that calculates the mass of the object by its volume:
Data:
m (mass) = 5 grams
v (volume) </span>≈ 0.689 cm³
d (density) = ?
Formula:
Solving:
2 equations:
37.5=5a+b
75=20a+b
We get: a=2.5, b=25
So, the linear function is: y=2.5x+25
Answer:
hello your question is incomplete attached below is the complete question
answer :
H0 : <em> u </em>= 21.62 ( Null hypothesis )
H1 : <em> u</em> = 21.62 ( alternative hypothesis )
Step-by-step explanation:
Formulating hypothesis that can be used to determine whether the population mean rate at 5 CCF of residential water discharged by U.S public utilities differs from $21.62
H0 : <em> u </em>= 21.62 ( Null hypothesis )
H1 : <em> u</em> = 21.62 ( alternative hypothesis )
