Step-by-step explanation:
5x+2y >=15
x>=0 y>=0
A) (0,0) --- (0,4) --- (21/11, 30/11)--- (3,0)
B) (0,0) ---(0,15/2) ---(21/11,30/11),--- (6,0)
C) (0,4) ---(21/11,30/11)--- (3,0)
D) (0,15/2)---(21/11,30/11)---(6,0)
The vertices of the feasible region of the inequality is given by 2x + 3y > 12 and 5x + 2y ≥ 15
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
2x + 3y > 12 be equation (1)
5x + 2y ≥ 15 be equation (2)
where x , y ≥ 0
Now , the inequalities are plotted on the graph ,
where the vertices of the feasible region is given by A , B and C
A ( 0 , 4 ) , B ( 21/11 , 30/11 ) , C ( 3 , 0 )
Hence , the inequalities are solved and the graph is plotted

Answer:
A IS THE ANSWER
Step-by-step explanation:
I USED DESMOS APP try it really helps
Answer:
Since the calculated Z= -1.886 lies within the Z∝ = ± 1.96 we fail to reject our null hypothesis that population mean is 31.8 oz. and not 32 ounces. There is evidence that Mill Valley Brewery is cheating customers by under-filling their bottles.
Step-by-step explanation:
Let the null hypothesis be
H0 : u = 31.8 oz against Ha: u ≠ 31.8 oz two tailed test
For a two tailed test and alpha = 0.05 the z∝ = ± 1.96
The rejection region is Z ≥ ± 1.96
Here n = 50
sample mean = x= 31.8 oz
and sample standard deviation= s= 0.75
Population mean= u= 32
Test statistics to be used is
Z= x- u / s/ √n which is approximately normal
Z= 31.8-32/0.75/ √50
z= -1.886
Since the calculated Z= -1.886 lies within the Z∝ = ± 1.96 we fail to reject our null hypothesis that population mean is 31.8 oz. and not 32 ounces. There is evidence that Mill Valley Brewery is cheating customers by under-filling their bottles.
