Answer: It is believed that exactly 20% of Evergreen Valley college students attended the opening night midnight showing of the latest harry potter movie.
Step-by-step explanation:
Since we have given that
n = 84
x = 11
So, 
p = 0.20
So, hypothesis:
so, test statistic value would be
At 1% level of significance, critical value would be
z= 2.58
Since 2.58>-1.604
So, We will accept the null hypothesis.
Hence, It is believed that exactly 20% of Evergreen Valley college students attended the opening night midnight showing of the latest harry potter movie.
Answer:
X) 7, 14, 28, 35
Y) 1, 2, 4, 5
Step-by-step explanation:
NO TIME TURN THE TEST IN!!!
Answer:
(7−2)(3)(24−11)
=(5)(3)(24−11)
=15(24−11)
=(15)(13)
=195
Step-by-step explanation:
Answer: The largest dimensions that are possible would be 50 foot by 125 foot.
Step-by-step explanation:
Since we have given that
Amount a farmer has available = $1500
Let x be the side perpendicular to the river.
Let y be the side parallel to the river.
Number of section perpendicular to the river = 3
cost of material for the side parallel to the river = $6 per foot
Cost of material for the side perpendicular to the river = $5 per foot
So, total cost becomes
Area would be
Now, put A' = 0 to get the critical points.
So, it becomes,
so, at x= 50 it will give maximum dimensions.
So, the largest dimensions that are possible would be 50 foot by 125 foot.
Answer:
(E) 1/5
Step-by-step explanation:
The probability that Harry will be chosen to be the secretary but not the president is 
The probability that Harry will be chosen to be the treasurer but not the president or secretary is 
Thus, the probability that Harry will be either the member chosen to be the secretary or the member chosen to be the treasurer is
