This question means that Coca-Cola, which has 65 grams of sugar in a can (I assume), has the same sugar content as 1.383 kg of carrots. Coca-Cola is a distractor in this problem. (1.383kg/65g)=(1kg/s)
Can you solve from there for s?
Answer: A
Step-by-step explanation: It is the only one being mirrored horizontally as, if the question said to find the one translated vertically, D would be the answer. C is incorrect because it just repeats the first figure and B is incorrect because it is translated vertically in an incorrect manner.
So in the end, The answer would be A.
Answer:
a.1.90 years
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
![\alpha = \frac{1-0.99}{2} = 0.005](https://tex.z-dn.net/?f=%5Calpha%20%3D%20%5Cfrac%7B1-0.99%7D%7B2%7D%20%3D%200.005)
Now, we have to find z in the Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so ![z = 2.575](https://tex.z-dn.net/?f=z%20%3D%202.575)
Now, find the margin of error M as such
![M = z*\frac{\sigma}{\sqrt{n}}](https://tex.z-dn.net/?f=M%20%3D%20z%2A%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D)
In which
is the standard deviation of the population and n is the size of the sample.
In this question:
![n = 25, \sigma = 3.8](https://tex.z-dn.net/?f=n%20%3D%2025%2C%20%5Csigma%20%3D%203.8)
So
![M = 2.575*\frac{3.8}{\sqrt{25}} = 1.90](https://tex.z-dn.net/?f=M%20%3D%202.575%2A%5Cfrac%7B3.8%7D%7B%5Csqrt%7B25%7D%7D%20%3D%201.90)
So the correct answer is:
a.1.90 years
