a) To find the probability that the mouse weighs less than 332 grams is calculated using the z-score formula which is: z= (x-μ)/σ where, x=332μ=409σ=24z= (332−409)/24z=−3.21
Hence, P (x < 332) = P (z < -3.21)
The probability that the mouse weighs less than 332 grams is approximately equal to 0.0007. Therefore, the answer is 0.0007 (rounded to four decimal places).
b) To find the probability that the mouse weighs more than 480 grams is calculated using the z-score formula which is: z= (x-μ)/σwhere,x=480μ=409σ=24z= (480−409)/24z=2.96
Hence, P (x > 480) = P (z > 2.96)
The probability that the mouse weighs more than 480 grams is approximately equal to 0.0015. Therefore, the answer is 0.0015 (rounded to four decimal places).
c) To find the probability that the mouse weighs between 332 and 480 grams is calculated using the z-score formula which is: P (332 < x < 480) = P (-3.21 < z < 2.96)
Hence, the probability that the mouse weighs between 332 and 480 grams is approximately equal to 0.9980. Therefore, the answer is 0.9980 (rounded to four decimal places).
d) The probability of a randomly chosen mouse weighing less than 332 grams is found to be P (x < 332) = 0.0007 which is less than 5%. Therefore, it is unlikely that a randomly chosen mouse would weigh less than 332 grams. Hence, the answer is "Yes, the likelihood is less than 5%".
e) To find the cutoff for the heaviest 6% of this type of mouse can be done by using the Z-table, that gives the z-score for any given probability. For the heaviest 6%, we need to find the z-score corresponding to a probability of 0.94 (100% - 6%). Hence, the Z-score for 0.94 probability is 1.55. Cutoff weight = μ + Z-score * σ= 409 + 1.55 * 24 = 447.2 ≈ 447 (rounded to the nearest whole gram). Therefore, the answer is 447 (rounded to the nearest whole gram).

2. A salary loan of 70,000 pesos is to be repaid by equal monthly payments for 18 months. The annual interest rate is 10% compounded monthly. How much is the monthly payment?
The monthly payment for a salary loan of 70,000 pesos at a 10% annual interest rate compounded monthly for 18 months is approximately 4,530.79 pesos.
To calculate the monthly payment for the salary loan, we can use the formula for the equal payment amount in an amortizing loan:
Payment = (Principal * Monthly Interest Rate) / (1 - (1 + Monthly Interest Rate)^(-n))
Where:
Principal = 70,000 pesos (loan amount)
Monthly Interest Rate = Annual Interest Rate / 12 = 10% / 12 = 0.0083333
n = number of payments (18 months)
Let's calculate the payment amount:
Payment = (70,000 * 0.0083333) / (1 - (1 + 0.0083333)^(-18))
Payment = 4,530.79 pesos
Therefore, the monthly payment for the salary loan is approximately 4,530.79 pesos.

New Mexico is the correct option with coordinates (-2.5,-1).
To find the midpoint between two points in the Cartesian plane, you can use the midpoint formula. The midpoint formula states that the coordinates of the midpoint between two points (x₁, y₁) and (x₂, y₂) are given by:
Midpoint = ((x₁ + x₂) / 2, (y₁ + y₂) / 2).
Here's a step-by-step process to find the midpoint:
1. Identify the coordinates of the two points you want to find the midpoint between. Let's say the coordinates are (x₁, y₁) and (x₂, y₂).
2. Add the x-coordinates of the two points together: x = x₁ + x₂.
3. Divide the sum by 2 to find the x-coordinate of the midpoint: x = x / 2.
4. Add the y-coordinates of the two points together: y = y₁ + y₂.
5. Divide the sum by 2 to find the y-coordinate of the midpoint: y = y / 2.
6. The coordinates (x, y) obtained from steps 3 and 5 represent the midpoint between the two given points.

Frank owns a $141,000 home, for which he has a 30-year mortgage in the
amount of $700 a month. Once he has paid off the mortgage, how much will
he have paid in interest?
A. $111,000
B. $120,000
C. $141,000
D. $109,000
Answer: the answer is A !!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Step-by-step explanation:
After paying off the mortgage, Frank will have accrued interest costs of $111,000 in total. $111,000 is the correct response.
What is compound interest?The interest earned on savings that are computed using both the original principal and the interest accrued over time is known as compound interest. [tex]A = P(1 + r/n)^{nt[/tex], where P is the principal balance, r is the interest rate, n is the number of times interest is compounded annually, and t is the number of years, which is the formula for compound interest.
The total amount paid by Frank over 30 years will be the product of the monthly payment and the number of months in 30 years:
The total amount paid = Monthly payment × Number of months
Total amount paid = $700/month × 12 months/year × 30 years
Total amount paid = $252,000
However, this total amount includes both the principal (the original loan amount of $141,000) and the interest. To find the amount of interest paid, we need to subtract the principal from the total amount:
Interest paid = Total amount paid - Principal
Interest paid = $252,000 - $141,000
Interest paid = $111,000
Therefore, Frank will have paid $111,000 in interest once he has paid off the mortgage. The answer is A. $111,000.

Which point is found on the line represented by the equation y+6=x ?
A (−5,1)
B (2,−4)
C (3,9)
D (6,6)
The point that satisfies the equation y+6=x is :
A (−5,1)
The line represented by the equation y+6 = x can be rewritten as x - y = -6. The equation is in the standard form:
Ax + By = C.
The x-intercept and y-intercept can be found using the standard form. Then, plot these points on the graph and draw a straight line between them to complete the graph of the equation.
Using the equation x - y = -6 to find the x-intercept, set y = 0 and solve for x.
Thus, x - 0 = -6x = -6
The x-intercept of the line is (-6, 0).
Using the equation x - y = -6 to find the y-intercept, set x = 0 and solve for y.
Thus, 0 - y = -6y = 6
The y-intercept of the line is (0, 6).
Plot the x-intercept (-6,0) and the y-intercept (0,6) on the coordinate plane. Then, draw the line through these points.
Now, we need to find which point is found on the line represented by the equation y+6 = x.
We can now plug in the values of the points to the equation:
y + 6 = x
x - y = -6(-5) - 1 = -6
The point A (-5,1) satisfies the equation since x - y = -6.
So, the answer is A (−5,1).

Define the following matrix norm for an n x n real matrix B: || B||M. = sup {||Bx|lo : X ER", ||$||20 = 1}. Show that || B||M. = max = max {Bijl {3B41 } 1
The matrix norm for an n x n real matrix B is ||B||M = max{|Bij|}
First, we will prove that ||B||M ≤ max{|Bij|}. Let's assume k is the index that achieves the maximum value, i.e., max{|Bij|} = |Bkj|. Consider the vector x = (0, 0, ..., 0, 1, 0, ..., 0)T, where the 1 is in the k-th position. Then, ||x||2 = 1. Now, let's calculate ||Bx||M:
||Bx||M = sup{||Bx||2 : ||x||2 = 1}
= sup{√((Bx)T(Bx)) : ||x||2 = 1}
= sup{√(xTBTBx) : ||x||2 = 1}
= sup{√(xTBTBx) : ||x||2 = 1, xk = 1}
≤ √((BTB)kk) (using the fact that xTBTBx is a scalar and sup{scalar} = scalar)
= √(|Bkj|²)
= |Bkj|
= max{|Bij|}
Therefore, we have shown that ||B||M ≤ max{|Bij|}.
Now, let's prove the reverse inequality: max{|Bij|} ≤ ||B||M. Consider the vector x = (x1, x2, ..., xn)T, where xi = 1 for the index i that achieves the maximum absolute value of Bij, and xi = 0 for all other indices. Then, ||x||2 = 1. Now, let's calculate ||Bx||M:
||Bx||M = sup{||Bx||2 : ||x||2 = 1}
= sup{√((Bx)T(Bx)) : ||x||2 = 1}
= sup{√(xTBTBx) : ||x||2 = 1}
= sup{√(xTBTBx) : ||x||2 = 1, xi = 1 for some i}
≥ √((BTB)ii) (using the fact that xTBTBx is a scalar and sup{scalar} = scalar)
= sqrt(|Bij|²)
= |Bij|
= max{|Bij|}
Therefore, we have shown that max{|Bij|} ≤ ||B||M.
Combining both inequalities, we conclude that ||B||M = max{|Bij|}.

You can practice on this problem. 1. A sample of men agreed to participate in a study to determine the relationship between several variables including height, weight, waste size, and percent body fat. A scatterplot with percent body fat on the y-axis and waist size (in inches) on the horizontal axis revealed a positive linear association between these variables. Computer output for the regression analysis is given below: Dependent variable is: WBE R-squared - 67.8% S - 4.713 with 250-2 - 248 degrees of freedom Variable Constant Waist Coefficient -42.734 1.70 se of coeff 2.717 0.0743 t-ratio -15.7 22.9 prob <.0001 <.0001 (a) Write the equation of the regression line (be sure to use correct notation and define your variables): (b) Explain/interpret the information provided by R-squared in the context of this problem. Be specific, (c) Calculate and interpret the correlation coefficient (r). (d) One of the men who participated in the study had waist size 35 inches and 10% body fat. Calculate the residual associated with the point for this individual.
(a) The equation of the regression line Percent Body Fat = -42.734 + 1.70 * Waist Size
(b) The higher the R-squared value, the better the regression line fits the data and the stronger the relationship between the variables.
(c) It means that as waist size increases, the percentage of body fat also tends to increase, and vice versa.
(d) The residual associated with this point is approximately -6.766
(a) The equation of the regression line can be written as:
Percent Body Fat = -42.734 + 1.70 * Waist Size
In this equation, Percent Body Fat represents the dependent variable, Waist Size represents the independent variable, -42.734 is the intercept (constant), and 1.70 is the coefficient for the Waist Size variable.
(b) R-squared is a measure of how well the regression line fits the data. In this context, R-squared of 67.8% indicates that 67.8% of the variation in the percent body fat can be explained by the linear relationship with waist size. The higher the R-squared value, the better the regression line fits the data and the stronger the relationship between the variables.
(c) To calculate the correlation coefficient (r), we can take the square root of the R-squared value. In this case, the correlation coefficient would be approximately √(0.678) ≈ 0.823.
Interpretation: The correlation coefficient (r) of 0.823 indicates a strong positive linear relationship between waist size and percent body fat. It means that as waist size increases, the percentage of body fat also tends to increase, and vice versa.
(d) To calculate the residual associated with the point for an individual with a waist size of 35 inches and 10% body fat, we need to substitute the waist size value into the regression equation and calculate the difference between the actual percent body fat and the predicted percent body fat.
Using the regression equation: Percent Body Fat = -42.734 + 1.70 * Waist Size
Substituting Waist Size = 35:
Percent Body Fat = -42.734 + 1.70 * 35 = -42.734 + 59.5 ≈ 16.766
The actual percent body fat for this individual is 10%. Therefore, the residual can be calculated as:
Residual = Actual Percent Body Fat - Predicted Percent Body Fat
Residual = 10 - 16.766 ≈ -6.766
The residual associated with this point is approximately -6.766. This indicates that the actual percent body fat is about 6.766 units lower than the predicted value based on the regression equation.
