What is 25% Of 30% Of 400?
1 answer:
Answer:
25% of 30% of 400 = 30
33% decrease in value
Step-by-step explanation:
You can either get 30% of 400 first then 25% of 400 or you can get the total percentage of 400.
Method 1:
30% of 400 = 0.3 of 400 = 0.3 * 400 = 120
25% of 120 = .25 of 120 = .25 * 120 = 30
Method 2:
30% of 25% = 0.3 * 0.25 = 0.075 = 7.5% of 400
7.5% of 400 = 0.075 of 400 = 0.075 * 400 = 30
5.) To find the percentage of the new price, you can build the equation below.
The percentage decrease in price is then 100% of the original price - 66.667% of the original price = 100% - 66.67% = 33.33% = 33% decrease.

1. μ = 306,500

5. σ = $2000
The standard deviation serves as a gauge for the degree of variation or dispersion among a group of numbers. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the mean of the collection.
With a standard deviation of $24,500 and an average mortgage debt of $306,500, Americans have a median mortgage debt.
<h3>According to the given information:</h3>The population's average is
μ = 306,500
Standard deviation for the general population is
σ = 24500
Imagine 150 Americans are chosen at random for the sample.
n= 150
The sample mean is roughly normally distributed as a result of the high sample size, which is supported by the central limit theorem.
The population mean and sample mean would be the same,
μ = μ =306,500
Here is how to calculate the sample standard deviation:
the sample size is n, and is the population standard deviation.
The necessary conditions are thus:
1. μ = 306,500
2.σ = 24,500
3. n = 150
4. μ = $306,500
5. σ = $2000
