QUESTION 2
aev [14]

The margin of error for a 95% confidence interval is 0.93.

mean (μ) = 23.4, standard deviation (σ) = 7.6, sample (n) = 254, confidence = 95% = 0.95

α = 1 - C = 1 - 0.95 = 0.05

α/2 = 0.05/2 = 0.025

The z score of α/2 is equal to the z score of 0.475 (0.5 - 0.025) which is equal to 1.96.

The margin of error (E) is given by:

E=z_\frac{\alpha}{2} *\frac{\sigma}{\sqrt{n} } \\\\E=1.96*\frac{7.6}{\sqrt{254} } \\\\E=0.93

The margin of error for a 95% confidence interval is 0.93.

The asset’s fourth full year of depreciation expense will be $6,666.67.

<h3>What is double-declining-balance?</h3>

An enhanced technique for recording loss over the lifetime of a product by adjusting the item's starting sales price by a discount factor.

An asset has a cost of $50,000, with a residual value of $10,000.

It has a life of 5 years and was purchased on January 1.

Then the asset’s fourth full year of depreciation expense will be

Annual depreciation = (cost – salvage value)/ useful life

Annual depreciation = (50000 – 10000) / 5 = $8,000

Year 1 Depreciation (for 10 months, from March to December) = $8,000 × 10/12 = $6,666.67.

Think about what you already know about math and baking.
alekssr [168]

Answer:

1. So if you want to know how is math related to baking, I will show you how. Firstly, if you bake a cake, you'll all have to use some measurement, and if you calculate anything wrong or place the crazy amount, the cake you're trying to bake would turn out awful. That's where maths come to play. You would have to calculate ratios and much more, for example, one tee-spoon of sugar to 2 tee-spoons of water it's a 1:2 ratio of sugar to water. If you try to make double the amount of cake, then you'll all have to double the ratio, too, so the ratio will become 2:4, and that's how we would use math in baking a cake. If you for any reason put more than the required amount, the whole cake would be ruined like it might be too sugary, and you will have to retry and bake another one.

2. Yes indeed I've tasted a mess up the cake, and I think that the problem was that the cake batter was much sugary than I expected and that's why you guys have to calculate the perfect amount of ingredients, and that's how maths would help us in baking a cake

hope this helps you btw
