The question can be formulated in the form of Linear equation in two variables.Linear equation in two variables can be written in the form of ax + by = c where a, b and c are constant terms and x, y are independent and dependent variables respectively. Here in this question the age of Pierre is represented as p and the age of Claude is represented as c. Since, Pierre is 3 years older than Claude then the equation representing their age can be formulated as:
p = c + 3 where p is Pierre's age and c is Claude's age and this represents that Pierre's age will be given when we will add 3 years more in the age of Claude.
Thus, the equation representing the age of Pierre is p = c + 3.

The probability that the interval estimation procedure will generate an interval that does not contain the actual value of the population parameter being estimated is the a. level of significance b. confidence level c. confidence coefficient d. error factor
The probability that the interval estimation procedure will generate an interval that does not contain the actual value of the population parameter being estimated is the level of significance.
The probability that the interval estimation procedure will generate an interval that does not contain the actual value of the population parameter being estimated is known as the level of significance. The level of significance (α) is the probability of making a Type I error, which is rejecting the null hypothesis when it is actually true. This is calculated by subtracting the confidence level from 1. For example, if the confidence level is 95%, then the level of significance is 1-0.95 = 0.05. This means there is a 5% chance of making a Type I error.
The confidence level is the probability that the interval will contain the actual value of the population parameter. It is calculated by 1 minus the level of significance. For example, if the level of significance is 0.05, then the confidence level is 1-0.05 = 0.95, which is 95%. This means there is a 95% chance that the interval will contain the actual value of the population parameter.
The confidence coefficient is the width of the interval, which is calculated by subtracting the lower bound from the upper bound of the interval.
The error factor is the difference between the estimated parameter value and the actual parameter value, which is calculated by subtracting the estimated parameter value from the actual parameter value.
The probability that the interval estimation procedure will generate an interval that does not contain the actual value of the population parameter being estimated is the level of significance.

a. The probability that die 1 beats die 2 is 1/4\
b. The probability that die 2 beats die 3 is 2/4 or 1/2
c. The probability that die 3 beats die 1 is 1/4.
Nothing strange occurred because the probabilities found are all based on the number of sides of each die and their values, which followed the expected outcome for any fair dice.
What is probability?Probability is described as the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
The probability that die 1 beats die 2 is 1/4 because die 1 has three sides with the value of 3, and die 2 has only one side with a value which is greater than 3. Hence there is a 1 in 4 chance that the result of rolling die 1 will be greater than the result of rolling die 2.

What is comparison?Comparing numbers in math is defined as a process or method in which one can determine whether a number is smaller, greater, or equal to another number according to their values.
Given that, 20 is to 28 as 3x-5 is to 3x-5+10
We see, 28-20 = 8
That mean, we need to add 8 to 20 or subtract 8 from 28 to make both equal,
Therefore, we can say, 20 is 8 less than 28, or 28 is 8 more than 20,
Similarly,
3x-5 and 3x-5+10
We see, 3x-5+10 - (3x-5)
= 3x+5-3x+5
= 10
That mean, we need to add 10 to 3x-5 or subtract 10 from 3x-5+10 to make both equal,
Therefore, 3x-5 is 10 less than 3x-5+10, or 3x-5+10 is 10 more than 3x-5,

Given that,
First choice, monthly salary of $1260 from a company
Second choice, base salary of $1200 and a 2% commission on the amount of furniture she sells during the month.
Let's call the amount of furniture Juliet sells each month "x".
With the second option, Juliet would receive a monthly salary of $1200 + 0.02x,
We want to find the value of x such that this salary is equal to $1260, so we can set up the following equation:
$1200 + 0.02x = 1260
Subtracting $1200 from both sides:
0.02x = 60

if we increase the compounding interval (from annual to daily) what will be the impact on 1) future value of an investment 2) present value of an investment.
Increasing the compounding interval from annual to daily has a positive impact on the future value of an investment and a negative impact on the present value of an investment.
The compounding interval refers to the frequency at which interest is calculated and added to the balance of an investment. Increasing the compounding interval from annual to daily will impact the future value and present value of an investment.
Future value of an investment: The future value of an investment increases with a higher compounding interval. With daily compounding, interest is calculated and added to the balance more frequently, leading to a higher future value of the investment. This is because each new interest calculation builds on the previous interest, which compounds over time to increase the overall value of the investment.Present value of an investment: The present value of an investment decreases with a higher compounding interval. This is because with a higher compounding interval, the expected future value of the investment is higher, making the present value lower. The present value represents the value of an investment today, and a higher future value means that the investment is worth more in the future, making the present value lower.Learn more about interest :

y = 7x - 7
Step-by-step explanation:
The equation for the function can be found using the slope-point form of a linear equation: y = mx + b, where m is the slope of the line and (x, y) is a point on the line.
To find the slope, we can use the two points:
m = (35 - 21) / (12 - 4) = 7
To find the y-intercept, we can substitute one of the points and the slope into the equation:
21 = 7 * 4 + b
Solving for b, we get:
b = 21 - 28 = -7
So, the equation of the line is:
y = 7x - 7

hint: decompose the shape into rectangle and triangle
The solution is, the area of the given figure is 156 ft^2.
What is area of trapezoid?The area of a trapezoid is found using the formula, A = ½ (a + b) h,
where 'a' and 'b' are the bases (parallel sides) and 'h' is the height .
here, we have,
from the given figure , we get,
the trapezoid's,
parallel sides are, 10 ft. & 3ft.
height =24 ft.
so, area = ½ (a + b) h,
i.e. A =156ft^2
Hence, The solution is, the area of the given figure is 156 ft^2.
