Answer:
the slope makes no sense
Step-by-step explanation:
Area = 1/2 (Base) (Height)
Area = 1/2 (12 in) (8 kn)
Area = 1/2 (96 in)
Area = 48 in^2
Volume = (Area) (Length)
Volume = (48 in^3) (13 in)
Volume = 624 in^3
Answer:
The null hypothesis ![H_o : \mu = 3.2 \ mg/dl](https://tex.z-dn.net/?f=H_o%20%3A%20%20%5Cmu%20%3D%203.2%20%5C%20mg%2Fdl)
The alternative hypothesis ![H_a : \mu > 3.2 \ mg/dl](https://tex.z-dn.net/?f=H_a%20%3A%20%20%5Cmu%20%3E%203.2%20%5C%20mg%2Fdl)
Step-by-step explanation:
From the question we are told that
The mean is ![\mu = 3.2 \ mg/dl](https://tex.z-dn.net/?f=%5Cmu%20%3D%203.2%20%5C%20%20mg%2Fdl)
The standard deviation is ![\sigma = 1.5 mg/dl](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%201.5%20mg%2Fdl)
The sample size is n = 25
The sample mean is ![\= x = 3.75 \ mg /dl](https://tex.z-dn.net/?f=%5C%3D%20x%20%3D%203.75%20%5C%20%20mg%20%2Fdl)
Generally
The null hypothesis is : That the mean of the Arsenic blood concentrations in healthy individuals is ![\mu = 3.2 \ mg/dl](https://tex.z-dn.net/?f=%5Cmu%20%3D%203.2%20%5C%20%20mg%2Fdl)
i.e
The null hypothesis ![H_o : \mu = 3.2 \ mg/dl](https://tex.z-dn.net/?f=H_o%20%3A%20%20%5Cmu%20%3D%203.2%20%5C%20mg%2Fdl)
The alternative hypothesis is : That the mean of the Arsenic blood concentrations in healthy individuals is greater than ![\mu = 3.2 \ mg/dl](https://tex.z-dn.net/?f=%5Cmu%20%3D%203.2%20%5C%20%20mg%2Fdl)
The alternative hypothesis ![H_a : \mu > 3.2 \ mg/dl](https://tex.z-dn.net/?f=H_a%20%3A%20%20%5Cmu%20%3E%203.2%20%5C%20mg%2Fdl)
it will be 2:30 because 12 to 3 is 3 hours and it lose 10 minots ber hour so it will he will lose 30 mins
Answer:
2 liters
Step-by-step explanation:
There are 5 beakers in total, in which David adds 0.4 liters into each of them.
To solve, multiply 5 with 0.4: 5 x 0.4 = 2.0
2.0 or 2 liters is your answer.
