a) The measure of side PN of the triangle is PN = 18 cm
b) The measure of ∠CDA = 45°
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the first triangle be represented as ΔOMP
Let the second triangle be represented as ΔOPN
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Now , the measure of OP = √ ( OM² - MP² )
Substituting the values in the equation , we get
The measure of OP = √ ( 25 )² - ( 7 )²
The measure of OP = √ ( 625 - 49 ) = √ ( 576 )
The measure of OP = 24 cm
And , the triangle OPN is a right triangle ,
So , the measure of PN = √ ( ON )² - ( OP )²
Substituting the values in the equation , we get
The measure of PN = √ ( 30 )² - ( 24 )²
The measure of PN = √ ( 900 - 576 ) = √ ( 324 )
The measure of PN = 18 cm
Therefore , the measure of PN of the triangle is 18 cm
b)
The two parallel lines are l₁ and l₂ where line t is the transversal
The measure of ∠FAE = 55°
The measure of ∠GAF = 80°
Now , the measures of angles in a straight line is 180°
So , the measure of ∠GAB = 180° - ( 55° + 80° )
The measure of ∠GAB = 45°
And , measure of ∠GAB = measure of ∠DAE ( alternate angles are equal )
So , the measure of ∠DAE = 45°
And , the measure of ∠DAE = the measure of ∠CDA ( alternate interior angles of a transversal line are equal )
Therefore , the measure of ∠CDA = 45°
Hence , the side PN of triangle is 18 cm and angle ∠CDA = 45°

balance will be due. If the interest rate is 6%, find the balloon payment due at
the end of 48 months.
OA. $19,726.27

The balloon payment due at the end of 48 months is approximately $19,726.27.
Answer choice (A) is the closest option.
What is the present value of an annuity?
Present value of an annuity is a financial concept that refers to the current value of a series of regular and equal payments or cash flows to be received or paid out in the future.
To find the balloon payment due at the end of 48 months, we can use the formula for the present value of an annuity:
PV = PMT x ((1 - (1 + r)^-n) / r)
where PV is the present value of the annuity (i.e. the balloon payment), PMT is the monthly payment, r is the interest rate per month (i.e. 6% / 12 = 0.005), and n is the number of periods (i.e. 48).
We can first find the total amount paid over 48 months:
Total payments = $199/month x 48 months = $9,552
We can then find the remaining balance on the car after 48 months:
Remaining balance = $24,000 - $9,552 = $14,448
Finally, we can use the present value formula to find the balloon payment:
PV = $199 x ((1 - (1 + 0.005)^-48) / 0.005) + $14,448
PV ≈ $19,726.27
Hence, the balloon payment due at the end of 48 months is approximately $19,726.27.

The rate of inflation for potatoes was 21%, for oranges it was 40%, and for ground beef it was 67%.
What do you mean by rate?In mathematics, rate is a concept used to describe the change in one quantity with respect to another. It is usually represented as a fraction or a ratio and can be thought of as a measure of how fast one quantity is changing with respect to another.
For example, the rate of change of position with respect to time is called velocity. The rate of change of velocity with respect to time is called acceleration. Similarly, the rate of change of any function with respect to its independent variable is called the derivative of the function, and it represents the instantaneous rate of change at a given point.
Rate can also be used to describe the relationship between two quantities that are changing at the same time. For example, in economics, the interest rate is the ratio of the amount of interest earned or paid to the amount of money invested or borrowed. In science, the rate of a chemical reaction is the change in the concentration of a reactant or a product over time.
The rate of inflation for each item can be calculated using the formula:
r = (P2/P1)¹/ⁿ - 1
where P1 is the price per pound in 2009 and P2 is the price per pound in the given year, and n is the number of years between the two prices (in this case, n = 1 year).
For Potatoes:
P1 = $0.620
P2 = $0.749
n = 1
r = (0.749/0.620)¹/¹ - 1 = 0.21 or 21%
For Oranges:
P1 = $0.910
P2 = $1.280
n = 1
r = (1.280/0.910)¹/¹ - 1 = 0.40 or 40%
For Ground beef:
P1 = $2.251
P2 = $3.775
n = 1
r = (3.775/2.251)¹/¹ - 1 = 0.67 or 67%
So, the rate of inflation for potatoes was 21%, for oranges it was 40%, and for ground beef it was 67%.

Side 1/10 original length what fraction of the original surface area is the new surface area
The fraction of the original surface area to the new surface area is 1/100.
How to find the fraction of the original surface area to the new surface area?The scale factor is the size by which the shape is enlarged or reduced. It is used to increase the size of shapes like circles, triangles, squares, rectangles, etc.
Since the ratio of the new side to original length is 1/10.
Thus, the fraction of the original surface area to the new surface area will be the square of the ratio of the length. That is:
fraction of length = new length/ original = 1/10
fraction of area = (1/10)² = 1/100
fraction of area = new area/original area
1/100 = new area/original area
new area = 1/100 * original area

This can be solved by using equation solving method.
What is personal expenditures?An expense classified as personal is one that is not related to a trade or enterprise, a passive activity, or an investment. Personal consumption spending is often divided into two categories: goods and services. Groceries, automobiles, and fuel are a few examples of products. Rent, medical treatment, and insurance are a few examples of services.
f(x) = 40.74x + 742.65
h(x) = 47.93x +725
For f(x) = h(x),
40.74x + 742.65 = 47.93x +725
47.93x - 40.74x = 742.65 - 725
x (47.93-40.74) = 17.65
x = 17.65 /7.19 = 2.455 years.
2.455 years after 1995, that is in 1998, these expenditures would be equal to each other.
The amount spent on each would be :-
40.74(2.455) + 742.65 = $842.667

What is the null hypothesis?The null hypothesis, denoted as H0, is a statistical hypothesis that assumes that there is no significant difference between a population parameter and a hypothesized value or between two or more population parameters.
Here,
If we choose a 5% significance level, this means that we are willing to reject the null hypothesis (Hop=0) if the probability of obtaining a test statistic as extreme as, or more extreme than, the observed value under the null hypothesis is less than 5%.
The observed value of the test statistic is z = -3.38. This means that the observed value is 3.38 standard deviations below the mean under the null hypothesis.
We can use a standard normal distribution table or calculator to find the probability of obtaining a z-score as extreme as -3.38 or less. The probability is approximately 0.0004, or 0.04%.

Based on the same previous scenario, calculate the deviation (score - mean). Square each response and then add the deviation squared. Divide the answer by n. What is the variance?
6, 7, 7, 8, 8, 8, 8, 9, 9, 10.
Step-by-step explanation:
1. Calculate the mean of the data: (6 + 7 + 7 + 8 + 8 + 8 + 8 + 9 + 9 + 10) / 10 = 8
2. Subtract the mean from each data point to get the deviation:
6 - 8 = -27 - 8 = -17 - 8 = -18 - 8 = 08 - 8 = 08 - 8 = 08 - 8 = 09 - 8 = 19 - 8 = 110 - 8 = 23. Square each deviation:
-2^2 = 4-1^2 = 1-1^2 = 10^2 = 00^2 = 00^2 = 00^2 = 01^2 = 11^2 = 12^2 = 44. Add up the squared deviations: 4 + 1 + 1 + 0 + 0 + 0 + 0 + 1 + 1 + 4 = 12
5.Divide the sum of squared deviations by the number of data points (n-1), which is 9 in this case: 12 / 9 = 1.33

On solving the provided question, we can say that there is a probability 20.66% chance that Mr. Larson rode his motorbike on both Monday and Tuesday.
What is probability?Probability theory is an area of mathematics that calculates the likelihood of an occurrence or a proposition being true. A risk is a number in the range of 0 and 1, whereas 1 implies certainty and a probability of roughly 0 indicates how likely an event seems to be to occur. Probability is a mathematical expression of the chance or chances that a given event will occur. Probabilities can alternatively be stated as integers between 0 and 1 or as % from 0% to 100%. the ratio of occurrences among equally likely choices that result in a certain event in comparison to all other outcomes.
Assuming that his decisions for the two days are independent, we must multiply the chance that he rides his motorbike on Monday by the probability that he rides it on Tuesday in order to get the likelihood that he does so on both Monday and Tuesday. Considering that his decisions on the two days are separate, Hence, the likelihood is:
(10/22) x (10/22) = 100/484 = 0.2066 or 20.66%
Hence, there is a roughly 20.66% chance that Mr. Larson rode his motorbike on both Monday and Tuesday.
