Answer:
The correct statement is
The null hypothesis is 
The alternative hypothesis is 
Step-by-step explanation:
From the question we are told that
The population proportion is p = 0.18
The sample size is n = 1240 airplane
The number of airplane is k = 310
Generally the sample proportion is

=> 
=> 
The null hypothesis is 
The alternative hypothesis is

Answer:
The unit rate is equal to 
Step-by-step explanation:
we know that
The unit rate is the ratio of two measurements in which the second term is equal to one
In this problem to find the unit rate, divide the total cost of cereal by the total weight of cereal
so

therefore
The unit rate is equal to 
Answer:
(1, 0)
Step-by-step explanation:
Please write this as y^2 = 4x; the " ^ " indicates exponentiation.
The appropriate equation for a horizontal parabola that opens to the right is
y^2 = 4px
Here, we are told that y^2 = 4x; this tells us that 4p = 4, and so p = 1.
Again, this parabola is a horizontal one and it opens to the right. p = 1 is the distance of the focus from the vertex, and in this case p = 1. Thus, the focus is at (1, 0) (situated on the x-axis).
Answer:
Volume = πr2h
= π×182×7
