Unit cost is what the drink would cost per fl. oz.
To find the unit cost, divide the total cost by the number of fl. oz.
$2.00 / 16 fl. oz. = $0.125 / fl. oz.
Answer:
53.3333.
Step-by-step explanation:
Since were asking to put 32 in the form of this ratio, we need to first turn the ratio into a fraction, in our case it is 5/3. Next we multiply 32 by 5/3 or to make it more simple multiply 32 by 5 to get 160, then divide 3 to get 53.3...
Hope this helps.
Answer:
A (361)
Step-by-step explanation:
A "perfect square trinomial" has the form
ax^2 + 2ab + b^2. If a happens to be 1, which it is in the given x^2 − 19x + c, then 2(1)(b) = - 19. Solving for b, we get b = -19/2.
Then b^2 in the general "perfect square trinomial" is the same as c: (-19/2)^2, or 90.25, or 90 1/4, or 361/4/
Choosing A (361) makes the given expression a perfect square trinomial.

Answer: 4
Step-by-step explanation:
For given Population standard deviation , the formula to sample size is given by :-
, where z* = Two-tailed critical value.
E = Margin of error.
Given : years
We know that , Critical value for 90% confidence interval : z* = 1.645
Margin of error : E=1.3 years
Then, the minimum sample size required to construct a 90% confidence interval for the population mean will be :-
[Rounded to the nearest whole number.]
Hence, the minimum sample size required = 4
