Answer:
Hello,
why not 700 ?
Step-by-step explanation:
![n=\overline{abcd}\\a\in \{3,4,5,6,7,8,9\}: 7\ possibilities\\b\in\{4,8\} :2\ possibilities\ :0 \ in\ USA\ is\ not\ a\ multiple\ of\ 4\\c \in\{0,1,2,3,4,5,6,7,8,9}: 10\ possibilities\\d \in \{0,2,4,6,8\}:5\ possibilities\\](https://tex.z-dn.net/?f=n%3D%5Coverline%7Babcd%7D%5C%5Ca%5Cin%20%5C%7B3%2C4%2C5%2C6%2C7%2C8%2C9%5C%7D%3A%207%5C%20possibilities%5C%5Cb%5Cin%5C%7B4%2C8%5C%7D%20%3A2%5C%20possibilities%5C%20%3A0%20%5C%20in%5C%20USA%5C%20%20is%5C%20not%5C%20a%5C%20multiple%5C%20of%5C%204%5C%5Cc%20%5Cin%5C%7B0%2C1%2C2%2C3%2C4%2C5%2C6%2C7%2C8%2C9%7D%3A%2010%5C%20possibilities%5C%5Cd%20%5Cin%20%5C%7B0%2C2%2C4%2C6%2C8%5C%7D%3A5%5C%20possibilities%5C%5C)
7*2*10*5=700
Impossible to reach 3000 since 2nd digit is 4 or 8.

Answer:
The value is ![z = \pm 1.645](https://tex.z-dn.net/?f=z%20%3D%20%5Cpm%201.645)
Step-by-step explanation:
From the question we are told that
The number of observation is greater than 50 i.e. n > 50
The level of significance is ![\alpha = 0.1](https://tex.z-dn.net/?f=%5Calpha%20%20%3D%200.1)
Generally given that n > 30 then we will make use of the z table
So
From the z table the critical value corresponding to the level of significance level for a two-tailed test is
![z = \pm 1.645](https://tex.z-dn.net/?f=z%20%3D%20%5Cpm%201.645)
Answer:
Step-by-step explanation:
Divide each of these prices by 16 because we can't have the cost per pound and divide by 1 pound when we want the price per ounce. There are 16 ounces in 1 pound.
For the flat-iron, the cost per ounce is 5.60/16 = 35 cents per ounce.
For the T-bone, the cost per ounce is 5.44/16 = 34 cents per ounce.
For the Strip, the cost per ounce is 4.48/16 = 28 cents per ounce.
For the Porterhouse, the cost per ounce is 4.96/16 = 31 cents per ounce.
It appears that the one that costs 34 cents per ounce is the T-Bone.
