Answer:
792 ounces
Step-by-step explanation:
At the time when the containers hold the same amount of water the value of y in the equations is the same, so
Solve the quadratic equation:
Take only the positive solution since x is positive (minutes)
Now, compute the amount of water y by replacing x = 12 in any of the two equations, for example in container A which is easier to calculate
y = 62(12) + 48 = 792
The correct answer is then 792 ounces
The answer is 32ft. What you have to do is multiply 10 and 6.4 which equals 64. Then you take 64 and divide it by 2 and you get the answer of 32. The equation goes like this 10ft X 6.4ft = 64ft/ 64ft divided by 2 = 32ft.
The second choice is the answer
Answer:
Die is not fair given that Pvalue< 0.05, hence we reject Null hypothesis
a) H0: Die = fair
b) Ha : Die ≠ fair
c) df = 5
Step-by-step explanation:
The expected frequency of every face values = 20
a) state Null hypothesis
H0: Die = fair
b) Alternate Hypothesis
Ha : Die ≠ fair
c) degree of freedom
df = ( n - 1 )
= ( 6 - 1 ) = 5
n = sample size ( number of faces a die has )
Note : After conducting hypothesis test
Pvalue ≈ 0.0026
test statistic ≈ 18.30
Hence we can conclude that die is not fair given that Pvalue < 0.05, hence we reject Null hypothesis
