$5.40 is what
percent of $4.50?
I
I will give braniest ❤️
Answers
120%
Step by step explanation
Step 1: We make the assumption that 4.50 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$x.
Step 3: From step 1, it follows that $100\%=4.50$100%=4.50.
Step 4: In the same vein, $x\%=5.40$x%=5.40.
Step 5: This gives us a pair of simple equations:
$100\%=4.50(1)$100%=4.50(1).
$x\%=5.40(2)$x%=5.40(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
$\frac{100\%}{x\%}=\frac{4.50}{5.40}$
100%
x%=
4.50
5.40
Step 7: Taking the inverse (or reciprocal) of both sides yields
$\frac{x\%}{100\%}=\frac{5.40}{4.50}$
x%
100%=
5.40
4.50
$\Rightarrow x=120\%$⇒x=120%
Therefore, $5.40$5.40 is $120\%$120% of $4.50$4.50.

since r is so widely used, it is appropriate to calculate r for nonlinear data.true/false
Answers
since r is so widely used, it is appropriate to calculate r for nonlinear data: False.
The calculation of r (Pearson's correlation coefficient) is based on the assumption that the relationship between the two variables is linear. Therefore, it is not appropriate to calculate r for nonlinear data as it may give misleading results.
In summary, it is not appropriate to calculate r for nonlinear data as it assumes a linear relationship between the variables. Other methods such as Spearman's rank correlation or Kendall's tau may be used for nonlinear data.
n: The correlation coefficient 'r' is specifically designed to measure the strength and direction of a linear relationship between two variables. While it is widely used, calculating 'r' for nonlinear data is not appropriate, as it will not accurately capture the true nature of the relationship between the variables.
When dealing with nonlinear data, it is better to use other statistical methods designed for such data, rather than relying on the correlation coefficient 'r'.

The size of the bookstore is classified as Small, Medium and Large. A double sampling was performed to estimate the total sales of a certain book last month in the center county region, which has 500 bookstores. In the 100 bookstores selected randomly in the first phase, 50 are small, 30 are medium and 20 are large. Suppose a stratified random sample of 10 small, 6 medium and 4 large bookstores are carried out, the sales of the book title are:
Small 50 30 34 45 60 32 28 33 40 45
Medium 60 90 80 72 94 86
Large 210 150 186 140
Required:
Estimate the total sales of the book title in this region and estimate its standard deviation( also called the standard error of the estimate)
Answers
The estimated total sales of the book title in the region is 475.294, and the standard deviation (standard error of the estimate) is approximately 0.118419.
1) Calculate the stratum weights:
For the small bookstores:
Weight for small bookstores = (Total number of small bookstores in the region) / (Total number of bookstores in the region)
Weight for small bookstores = 50 / 500
Weight for small bookstores = 0.1
For the medium bookstores:
Weight for medium bookstores = (Total number of medium bookstores in the region) / (Total number of bookstores in the region)
Weight for medium bookstores = 30 / 500
Weight for medium bookstores = 0.06
For the large bookstores:
Weight for large bookstores = (Total number of large bookstores in the region) / (Total number of bookstores in the region)
Weight for large bookstores = 20 / 500
Weight for large bookstores = 0.04
2) Estimate the total sales for each stratum:
To estimate the total sales for each stratum, we multiply the average sales per bookstore in that stratum by the total number of bookstores in that stratum and then multiply it by the corresponding stratum weight.
For the small bookstores:
Average sales per small bookstore = (50 + 30 + 34 + 45 + 60 + 32 + 28 + 33 + 40 + 45) / 10
Average sales per small bookstore = 387 / 10
Average sales per small bookstore = 38.7
Total estimated sales for small bookstores = (Average sales per small bookstore) * (Total number of small bookstores in the region) * (Weight for small bookstores)
Total estimated sales for small bookstores = 38.7 * 50 * 0.1
Total estimated sales for small bookstores = 193.5
For the medium bookstores:
Average sales per medium bookstore = (60 + 90 + 80 + 72 + 94 + 86) / 6
Average sales per medium bookstore = 482 / 6
Average sales per medium bookstore = 80.33
Total estimated sales for medium bookstores = (Average sales per medium bookstore) * (Total number of medium bookstores in the region) * (Weight for medium bookstores)
Total estimated sales for medium bookstores = 80.33 * 30 * 0.06
Total estimated sales for medium bookstores = 144.594
For the large bookstores:
Average sales per large bookstore = (210 + 150 + 186 + 140) / 4
Average sales per large bookstore = 686 / 4
Average sales per large bookstore = 171.5
Total estimated sales for large bookstores = (Average sales per large bookstore) * (Total number of large bookstores in the region) * (Weight for large bookstores)
Total estimated sales for large bookstores = 171.5 * 20 * 0.04
Total estimated sales for large bookstores = 137.2
3) Estimate the total sales for the region:
The estimated total sales for the region is the sum of the estimated total sales for each stratum.
Estimated total sales for the region = Total estimated sales for small bookstores + Total estimated sales for medium bookstores + Total estimated sales for large bookstores
Estimated total sales for the region = 193.5 + 144.594 + 137.2
Estimated total sales for the region = 475.294
Therefore, the estimated total sales of the book title in the region is 475.294.
4) Estimate the standard deviation (standard error of the estimate):
The standard deviation (standard error of the estimate) is calculated using the formula:
Standard deviation (standard error of the estimate) = Square root of [(Variance of the sample mean for each stratum) / (Total number of bookstores sampled)]
Since we have a double sampling method, we need to consider both phases of sampling.
For the small bookstores:
Sample mean for small bookstores = Average sales per small bookstore = 38.7
Sample variance for small bookstores = \([(50 - 38.7)^2 + (30 - 38.7)^2 + ... + (45 - 38.7)^2] / (10 - 1)\)
Sample variance for small bookstores = 58.9
Repeat the same steps to calculate the sample variance for the medium and large bookstores:
Sample variance for medium bookstores = 133.556
Sample variance for large bookstores = 736.667
Calculate the total variance of the sample mean for each stratum:
Total variance of the sample mean = \((58.9 * 0.1^2) + (133.556 * 0.06^2) + (736.667 * 0.04^2)\)
Total variance of the sample mean = 0.315079
Standard deviation = \(\sqrt{(0.315079 / 20)}\)
Standard deviation (standard error of the estimate) = 0.118419
Therefore, the standard deviation (standard error of the estimate) for the total sales of the book title in the region is approximately 0.118419.

Choose an integer randomly from the set . Square it, then subtract 1. What is the probability that the resulting value is a prime number
Answers
To find the probability that the resulting value is a prime number when an integer is randomly selected from the set and squared, then subtracted by 1, we need to consider a few factors.
Let's break down the steps:
1. Selecting an integer randomly from the set:
- The set of integers is not provided, so let's assume we are selecting from the set of positive integers.
2. Squaring the selected integer:
- When an integer is squared, we multiply it by itself. For example, if we select the integer 2, squaring it would give us 2 * 2 = 4.
3. Subtracting 1 from the squared value:
- After squaring the selected integer, we subtract 1 from the squared value. Using the previous example, if we had squared the integer 2, we would subtract 1 from 4, resulting in 4 - 1 = 3.
4. Checking if the resulting value is a prime number:
- To determine if the resulting value is a prime number, we need to check if it is divisible only by 1 and itself. In the example above, the resulting value was 3, which is a prime number since it is only divisible by 1 and 3.
Now, let's discuss the probability:
Since we are randomly selecting an integer from the set, the probability of selecting any specific integer is the same for all integers in the set. Therefore, the probability of selecting any particular integer is 1 divided by the total number of integers in the set.
However, the set of integers is not specified, so we cannot determine the exact probability without additional information. If you have a specific set of integers in mind, please provide it so that I can assist you further with the calculation of the probability.

find the number of ways a six-sided die can be constructed if each side is marked differently with dots.
Answers
The number of ways a six-sided die can be constructed with different markings on each side is 720.
If we have a six-sided die, each side can be marked differently with dots. This means that we can have six different options for the first side, five different options for the second side (since one of the dots has already been used), four different options for the third side (since two of the dots have already been used), three different options for the fourth side, two different options for the fifth side, and only one option left for the sixth side.
Therefore, to find the number of ways a six-sided die can be constructed if each side is marked differently with dots, we need to multiply all of these different options together. That is, we need to find the product of 6 x 5 x 4 x 3 x 2 x 1, which is equal to 720.
Therefore, there are 720 different ways that a six-sided die can be constructed if each side is marked differently with dots. This is because there are 720 different permutations of six objects, where each object can only appear once, and the order matters.
