Micah withdrew $4.50 from his bank account. Write a rational number to represent this situation
The amount Micah withdrew can be represented as a rational number as 4.5 or 9/2.
Rational Numbers, and it's application in this problemA rational number is a number that can be expressed as the ratio of two integers. In this situation, we can represent the amount Micah withdrew as a rational number by expressing it as a fraction.
To do this, we can treat the dollar amount as a whole number (i.e. 4 dollars), and the cents amount as another whole number (i.e. 50 cents), and then express the total amount as a fraction with the sum of these two whole numbers as the numerator and 100 as the denominator (since there are 100 cents in a dollar).
So, the rational number representation of Micah's withdrawal would be:
(4 * 100 + 50) / 100 = 450 / 100 = 9 / 2
In other words, Micah withdrew 9/2 dollars from his bank account.

Negative sixteen plus the quotient of a number and 2 is 35.
This can be written as,
Quotient of a number and 2.
x ÷ 2 = M (quotient)
So,
-16 + M = 35
Now,
Solve for M.
M = 35 + 16
M = 51
Now,
x ÷ 2 = 51
x/2 = 51
x = 51 x 2
x = 102

Janet is thinking of a two-digit positive whole number. It can be found by using n>56−22 , where n stands for Janet's number.
What are 3 numbers that could be Janet's number?
Explain why those numbers are possible
The numbers that are possible for Janet's number are 335, 36, and 37.
We start by finding the value of n using the equation n > 56 - 22. Solving this equation, we get n > 34.
So, Janet's number must be greater than 34, and it must be a two-digit positive whole number. Based on this, we can conclude that the following numbers are possible for Janet's number:

Answer: a. What is the proportion of current smokers among the 1685 high school students surveyed?
The proportion of current smokers among the 1685 high school students surveyed is 437/1685 = 0.259 or 26%.
b. What is the point estimate for the population proportion of all high school students who smoke?
The point estimate for the population proportion of all high school students who smoke is 0.259.
c. What is the 95% confidence interval for the population proportion of all high school students who smoke?
The 95% confidence interval can be calculated using the formula:
point estimate ± 1.96 * standard error
where standard error = square root of (point estimate * (1 - point estimate) / sample size)
standard error = square root of (0.259 * (1 - 0.259) / 1685) = 0.012
95% confidence interval = 0.259 ± 1.96 * 0.012
= 0.259 ± 0.023
= [0.236, 0.282]
So, the 95% confidence interval for the population proportion of all high school students who smoke is between 23.6% and 28.2%.

y = -8x - 21 y = 6x + 7 solve in Equal Values Method
The two resulting equations are set equal to one another and solved for the values of the variables. Therefore, the solution to the system of equations is x = 3 and y = -45.
The equal values method is a way of solving systems of equations. It involves isolating each variable on its own side of the equation and then setting the two equations equal to one another. This results in an equation with only one variable, which can then be solved. For example, the system of equations given is -8x - 21 = 6x + 7. To solve this system with the equal values method, one must first isolate the variables. The first equation can be rearranged to -8x = 21 + 6x, and then solved for x to find x = 3. Then, the same value of x can be substituted into either of the original equations to solve for y. For example, substituting x = 3 into the first equation gives -8(3) - 21 = -24 - 21 = -45, so y = -45. Therefore, the solution to the system of equations is x = 3 and y = -45.

Your lawn mower does not start on the first try 1/6 of the time. Design and usr simulation with number cubes to estimate the probability that your lawn mower will not start on the first try exactly one of the next two times you mow the lawn
Where the above condition exists, the probability that the lawn mower will not start on the first try exactly once out of the next two times you mow the lawn is 5/18, or approximately 0.278.
What is the rationale for the above response?We can calculate the probability that the lawn mower will not start on the first try exactly once out of the two rounds using a binomial probability distribution.
Let's define a success as the lawn mower starting on the first try, and a failure as the lawn mower not starting on the first try.
The probability of a success is p = 5/6, since the lawn mower does not start on the first try 1/6 of the time.
The probability of a failure is q = 1/6.
The probability of getting exactly one failure out of two trials can be calculated using the binomial probability formula:
P(X = 1) = (2 choose 1) * (5/6)^1 * (1/6)^1
where (2 choose 1) is the number of ways to choose one failure out of two trials.
Simplifying this formula, we get:
P(X = 1) = 2 * 5/6 * 1/6
P(X = 1) = 5/18
Therefore, the probability that the lawn mower will not start on the first try exactly once out of the next two times you mow the lawn is 5/18, or approximately 0.278.

Adobe mud can be poured into molds to make bricks. Each brick is a rectangular prism with a width 4 inches less than its length and a height 6 inches less than its length. Each mold holds 576 cubic inches of mud. What are the dimensions of the mold?
Answer: Let's call the length of the brick "l". Then, the width is "l - 4" and the height is "l - 6".
The volume of the brick can be expressed as:
V = l * (l - 4) * (l - 6)
Since each mold holds 576 cubic inches of mud, we can set the volume of the brick equal to 576 and solve for l:
l * (l - 4) * (l - 6) = 576
Expanding and simplifying the left side of the equation, we get:
l^3 - 10l^2 + 24l - 576 = 0
This is a cubic equation, and finding the exact value for l can be difficult. However, we can use numerical methods, such as the bisection method or Newton's method, to find an approximate value.

Hank bought a 4 room home for a rental, he put 20% down on the $300,00. 00 rental unit. How much will he be able to depreciate?
If Hank bought a 4 room home for a rental, and he put 20% down on the $300,00. 00 rental unit, the annual depreciation amount would be $8,727.27 .
To determine the depreciation amount, we first need to determine the depreciable basis of the rental property. The depreciable basis is the portion of the property's value that can be depreciated over time.
In this case, Hank put 20% down on a $300,000 rental unit, which means he paid $60,000 as a down payment. Therefore, the depreciable basis of the rental property is the remaining $240,000 ($300,000 - $60,000).
The IRS allows rental property owners to depreciate the depreciable basis of their property over 27.5 years using the straight-line method. To calculate the annual depreciation amount, we divide the depreciable basis by the number of years of useful life.
So, in this case, the annual depreciation amount would be $8,727.27 ($240,000 / 27.5). This means that Hank would be able to deduct $8,727.27 from his rental income each year for 27.5 years to account for the wear and tear of the property.

How to obtain the limit of the function?Following the standard procedure to obtain the limit of the function, merely obtaining the numeric value at x = 1, the limit is undetermined at x = 0, as follows:
0/0.
Hence the can apply the L'Hospital Rule, trying to find the derivative at the numerator and the denominator, hence:
[cos(x)sqrt(cos(2x))]' = [-sin(x)sqrt(cos(2x)) - 2sin(2x)cos(x)/sqrt(sin(2x))].[x²]' = 2x.At x = 0, the limit would again assume an undetermined value of 0/0, hence the L'Hospital Rule is applied again, hence:
[-sin(x)sqrt(cos(2x)) - 2sin(2x)cos(x)/sqrt(sin(2x))]' = cos(2x)sqrt(cos(2x)).[2x]' = 2.Now the function is:
f(x) = cos(2x)sqrt(cos(2x))/2.
