<h3>
Answer: 1/2</h3>
Explanation:
The list of items we want to land on are {1,2,3} which are all less than 4. There are A = 3 items in this set.
The list of possible outcomes are {1,2,3,4,5,6}. There are B = 6 total outcomes.
Divide the values of A and B to get A/B = 3/6 = 1/2.
The conclusion of the research is that we reject the null hypothesis and we conclude that the bag filling machine does not work correctly at the 426 gram setting.
<h3>How to solve hypothesis testing?</h3>
We are given;
Population Mean; μ = 426
Sample mean; x' = 433
Sample size; n = 13
Standard deviation; s = 29
significance level; α = 0.05
Let us define the hypotheses;
Null Hypothesis; H₀: μ = 426 g
Alternative Hypothesis; H_a: μ < 426 g
Formula for the z-score here is;
z = (x' - μ)/(s/√n)
z = (433 - 426)/(29/√13)
z = 0.87
From online p-value from z-score calculator, we have;
p-value = 0.1922
This p-value is greater than the significance value and as such we reject the null hypothesis and we conclude that the bag filling machine does not work correctly at the 426 gram setting.

Answer:
A. Balance hormones
Explanation:
Lipids help in the balancing of hormonal activities in the body. Some hormones are lipid soluble, which means that they can get dissolved in the lipids and can be transported throughout the body.
In addition to that, every cell in the body has a cell membrane which is made up of lipids. The sex hormone of humans are made up of cholesterol which is a lipid. This makes lipids play an important role in the balancing of hormones in the body, they are necessary in the production of hormones.
Answer:
The time it takes light from a flash camera to reach a subject 6.0 meters across a room in scientific notation is 2.0 *10^-8 s.
The oxidation state of Lithium changed from 0 to +1
The oxidation state of hydrogen changed from +1 to 0.
<h3>What is the oxidation state of the elements in the reaction?</h3>
The equation of the redox reaction is given as follows:
2 Li + 2 H₂O → 2 LiOH + H₂
The oxidation states of the elements changed as follows:
The oxidation state of Lithium changed from 0 to +1
The oxidation state of hydrogen changed from +1 to 0.
In conclusion, the reaction is a redox reaction.
