Variation can be direct, inverse or joint.
The value of B when a = 48 and c = 4 is 8
The joint variation is represented as:
Express the variation as equation
Make k the subject of the formula
If a = 24 when b = 8 and c = 2, we have:
So, becomes
Make B the subject
When a = 48 and c = 4, we have:
Divide
Hence, the value of B is 8

From the information given above, the results from chi square are suggestive of the fact that the there is a statistically significant relationship between marital status (MARITAL) and (Polviews).
<h3>What does the Chi Square test show?</h3>
The Chi-square test is designed to determine the likelihood that an observed distribution is attributable to chance.
It is also known as a "goodness of fit" statistic since it assesses how well the observed data distribution matches the predicted distribution if there is independence between the variables.

Based on the calculations, the molar solubility of AgCl in 0. 500 M of NH₃ is equal to 2.77 × 10⁻² M.
<u>Given the following data:</u>
- Ksp of mg(oh)₂ = 1.8 × 10⁻¹⁰
- Concentration of NH₃ = 0.500
- Kf of ag(nh₃)₂⁺ = 1.7 × 10⁷
<h3>How to determine the molar solubility.</h3>
First of al, we would write the properly balanced chemical equation for this chemical reaction:
Ksp = 1.8 × 10⁻¹⁰
Kf = 1. 7 × 10⁷
K = Ksp × Kf
K = 1. 80 × 10⁻¹⁰ × 1.7 × 10⁷
K = 3.06 × 10⁻³
Mathematically, the Ksp for the above chemical reaction is given by:
x = 2.77 × 10⁻² M.

I can’t see the story? What is the name of it. So I can answer this question
Based on the excerpt and the knowledge of the history, the reason the Americans lost confidence in business following the crash is that:
- People worked diligently to participate in the building of the American dream with the understanding they would profit.
The Crash of the stock Market
This was a period were there was a great decline in the value of stock in the US. This period was what gave way to the Great depression of the 1920s.
Americans had expected to make a lot of money by investing money in stocks. But unfortunately, it crashed instead. This made them to lose faith in the instead.
