If a rectangle has a length that is three times the width increased by 4. Find the dimensions of both the length and width if the
perimeter of the rectangle is 80 centimeters
Answers
Answer:
Step-by-step explanation:
Formula
The formula for perimeter is
P = 2L + 2w
Givens
Let the width = w
Length = 3w + 4
P = 80 cm
Solution
P = 2L + 2w
80 = 2(3w + 4) + 2w Remove the brackets
80 = 6w + 8 + 2w Combine
80 = 8w + 8 Subtract 8 from both sides
80-8 = 8w + 8-8 Combine
72 = 8w Divide both sides by 8
72/8 = 8w'8
9 = w
Answer
w = 9
L = 3*w + 4
L = 3*9 + 4
L = 31

If your brother borrows $835 at 10% interest rate for eleven years, how much interest will he pay?
Answers
For this case, your interest rate will be (. 11 x 100 = 11) 11%. Step 3: Apart from this, you can also calculate your time period involved, principal amount and interest amount paid in a specific time period if you have other inputs available with you. Calculate interest amount paid in a specific time period, I = Prt
Answer:
918.50 in interest over 11 years.
Step-by-step explanation:
Comment
You have to make an assumption here. The assumption is that this is simple interest.
So if the brother pays 10% each year, he is paying
10/100 * 835 each year in interest
10/100 * 835 = 83.50 every year.
There are 11 years, so the total interest paid is 11 * 83.50 = 918.50 dollars in total.. That's more than what he borrowed!

Answers
When comparing two sample means, we can safely reject the null hypothesis if the calculated test statistic exceeds the critical value corresponding to the chosen significance level.
In hypothesis testing, when comparing two sample means, we typically perform a t-test or z-test depending on the characteristics of the data and assumptions. The null hypothesis assumes that there is no significant difference between the means of the two samples.
To determine whether we can reject the null hypothesis and conclude that there is a significant difference, we calculate a test statistic. The specific test statistic (t or z) depends on factors such as sample size and whether population parameters are known.
Next, we compare the calculated test statistic to the critical value. The critical value is determined based on the chosen significance level (commonly denoted as α). If the calculated test statistic exceeds the critical value, we reject the null hypothesis, indicating that there is evidence to support a significant difference between the two sample means.
The significance level determines the threshold for rejecting the null hypothesis and is typically set at 0.05 (5%) or lower, depending on the desired level of confidence.

Answers
The subgroup N = {1, 9} is a normal subgroup in U(16) because it is closed under the group operation and conjugation by any element of U(16). The factor group U(16)/N is isomorphic to the Klein four-group, V4.
To show that N = {1, 9} is a normal subgroup in U(16), we need to demonstrate that it is closed under the group operation and that conjugation by any element of U(16) leaves N invariant. In this case, U(16) represents the group of units modulo 16, which consists of the positive integers less than 16 that are coprime to 16.
First, let's verify closure under the group operation. The elements 1 and 9 are both coprime to 16 and satisfy the condition gcd(a, 16) = 1, where a is an element of U(16). Multiplication of 1 and 9 will yield another element in U(16) that is coprime to 16, so closure is satisfied.
Next, we need to show that N is invariant under conjugation by any element of U(16). Let x be an element of U(16), and let n be an element of N. We want to prove that xnx^(-1) is also an element of N. Since the operation in U(16) is multiplication modulo 16, we have:
xnx^(-1) ≡ n (mod 16)
The subgroup N = {1, 9} is a normal subgroup in U(16) because it satisfies closure under the group operation and conjugation by any element of U(16). The factor group U(16)/N is isomorphic to the Klein four-group, V4, which consists of the cosets {N, 3N, 5N, 7N}.

Binomial expansion is a process of expanding a power (x+y)n in the form of sum of terms, where n is any positive integer. The binomial expansion is done with the help of the binomial theorem.
The binomial theorem states that for a binomial expression (x+y)n, the expansion can be obtained by summing the n+1 terms which are given by:T(n+1) = nCrx^(n-r)y^rwhere n is the power of the binomial, r is the power of x in a term and (n-r) is the power of y in the term.
This formula is used to find any specific term in the expansion of the given binomial. In this answer, we found the coefficients of specific terms in the expansion of given binomials.
The coefficients were found using the formula mentioned above. In the first part, the coefficient was zero which implies that there is no term with x³y4 in the expansion of (x+y)².
In the second part, the coefficient was found to be 4 which means that there are four terms with x^5y^2 in the expansion of (2x-y)².
In the third part, the coefficient was 1 which means that there is only one term with x²y+z*w² in the expansion of (2x + y - z+w)º. Hence, we have found the coefficients of specific terms in the expansion of given binomials.
The binomial theorem provides a way to expand any power of the binomial (x+y)n into the sum of terms. The coefficients of any specific term in the expansion can be found using the formula mentioned above. In this answer, we have found the coefficients of specific terms in the expansion of three different binomials.

What is the coefficient of determination for a linear model fitting the following bivariate dataset?
Answers
The coefficient of determination for a linear regression model fitting with bivariate dataset ( scatterpot present in above figure) is equals to the 90.097.
When we study about linear regressions, usually analyze two coefficients that help us to know about the quality of the regression model and strength of linear relationship between the variables. One is called the coefficient of determination, denoted by R². Consequently, by observing a scatter plot, we can estimate the value of these coefficients. We have a scatterpot for a linear model fitting of the bivariate dataset is present in above figure. Coefficient of determination is always positive. When data are very closely arranged along a approximate line, then coefficient of determination is more near to 1 (In percentage it is 100). Here points are almost closely arranged . So percentage should be near to 100. So possible answer is 90.097. Hence, the answer is 90.097.

when will a normal probability plot appear linear and what does that indicate?
Answers
A normal probability plot (also known as a normal plot or a probability plot) is a graphical tool that can be used to assess whether a set of data follows a normal distribution.
When the data being plotted follows a normal distribution, the points on the plot will appear roughly linear, with deviations from linearity being relatively minor. In other words, the plot will form a straight line.
If the plot deviates significantly from a straight line, it suggests that the data may not be normally distributed. The shape of the plot can indicate whether the data is skewed or has heavy tails compared to a normal distribution.
Therefore, a normal probability plot appearing linear indicates that the data follows a normal distribution. It is important to note that this is only one way to check for normality, and it is always recommended to use multiple methods to verify the normality assumption before applying statistical tests that assume normality.
