Answer:
about 68% of brand x’s batteries have a lifespan between 95.2 hours and 108.8 hours. about 68% of brand y’s batteries have a lifespan between 98.6 hours and 101.4 hours. the life span of brand y’s battery is more likely to be consistently close to the mean.
Explanation:
According to the empirical rule (68–95–99.7 rule) for a normal distribution, 68% of the data falls within the first standard deviation (μ ± σ).
Given for brand x, mean (μ) = 102 hours and standard deviation (σ) = 6.8 hours.
first standard deviation (μ ± σ) = 102 ± 6.8 = (95.2, 108.8)
about 68% of brand x’s batteries have a lifespan between 95.2 hours and 108.8 hours.
Given for brand y, mean (μ) = 100 hours and standard deviation (σ) = 1.4 hours.
first standard deviation (μ ± σ) = 100 ± 1.4 = (98.6, 101.4)
about 68% of brand x’s batteries have a lifespan between 98.6 hours and 101.4 hours.
Since the standard deviation of brand y is smaller than that of brand x, brand y battery is more likely to be consistently close to the mean
The amount of applied overhead is $1,000.

What is inventory?</h3>
- The products and materials that a company keeps on hand with the intention of reselling, producing, or using them are referred to as inventory or stock.
- The main focus of inventory management is determining the location and shape of stocked commodities.
<h3>What is material cost?</h3>
- The price of direct materials is directly related to the unit of production and is immediately identifiable.
- For instance, the price of glass is a direct material expense in the production of light bulbs.
- The primary component needed for the production of commodities or products was material.
<h3>Solution -</h3>
To find the amount applied overhead:
3200 - ( 1400 + 800 ) = 3200 - 2200
= $1,000
Therefore, the amount of applied overhead is $1,000.

Answer:
c. Erie s ROE will remain the same
Explanation:
As the return on asset is calcualte using the asset figure it will not change with a financial leverage measurement.
As the financial leverage acts in the composition of other side of the accounting (assets = liabilitis + equity) it will change the return on equity, the debt ratio and other metric related to this side but, not the return on assets.
Answer:
The total monthly fixed cost and the variable cost per hour is $1,540 and $23
The average contribution margin per hour is $27
Explanation:
The computation of the fixed cost and the variable cost per hour by using high low method is shown below:
Variable cost per hour = (High Operating cost - low operating cost) ÷ (High service hours - low service hours)
= ($11,200 - $4,300) ÷ (420 hours - 120 hours)
= $6,900 ÷ 300 hours
= $23
Now the fixed cost equal to
= High operating cost - (High service hours × Variable cost per hour)
= $11,200 - (420 hours × $23)
= $11,200 - $9,660
= $1,540
For computing the contribution margin per hour, first we have to compute the revenue per hour which is shown below:
= Revenue ÷ service hours
= $6,000 ÷ 120 hours
= $50
We know that,
The contribution per hour = Revenue per hour - variable cost per hour
= $50 - $23
= $27
