Tamika was out at a restaurant for dinner when the bill came. She wanted to leave a tip of 29%. What number should she multiply the cost of the meal by to find the total plus tip in one step?
Answers
The number Tamika should multiply the cost of the meal by to find the total plus tip in one step is 1.29.
Let x be the cost of meal.
Let m be the number she should multiply the cost of the meal by to find the total plus tip in one step.
Then Total amount Tamika pays(including tip) = mx.
We need to determine the value of m.
Given Tamika wanted to leave a tip of 29% of the bill amount.
Then the amount of tip \(= (\frac{29}{100} )x = 0.29x\)
Thus, Total amount Tamika pays(including tip) = x + 0.29x = 1.29.
We found Total amount Tamika pays(including tip) = mx.
Comparing we have m = 1.29.
A bill amount is the total cost of goods or services purchased or availed of by an individual or organization. It represents the amount that the customer owes to the provider of the goods or services. A bill may include various components such as the price of the goods or services, taxes, fees, and other charges that may be applicable.
When a customer receives a bill, they typically have a certain amount of time to pay it in full. Failure to pay the bill on time may result in additional fees, penalties, or even legal action. It is important for customers to carefully review their bills to ensure that they are accurate and that they understand all of the charges included.

Answers
The lower quartile is 2, the median is 5 and the upper quartile is 8.
What are quartiles?
The values that divide a list of numerical data into three quarters are known as quartiles.
We are given a data set as 1, 2, 3, 5, 5, 8, 8
From this, we get the median as 5 as median is the middle number of the data set.
We know that lower quartile is the median of the lower half of the data.
So, lower quartile is 2.
Upper quartile is the median of the upper half of the data.
So, upper quartile is 8.
Hence, the lower quartile is 2, the median is 5 and the upper quartile is 8.

Thirteen years ago, you deposited $2400 into a superannuation
fund. Eight years ago, you added an additional $1000 to this
account. You earned 8%, compounded annually, for the first five
years, and 5.
Answers
The total amount money after thirteen years of savings will be $5030.63
To calculate the amount of money in the account today, we need to calculate the future value of each contribution separately and then add them together.
Let's start by calculating the future value of the initial deposit of $2400 over the first five years at an interest rate of 8% compounded annually.
Using the formula for compound interest:
Future Value = \(Principal\) * \((1 + Interest Rate)^{Time}\)
Future Value = $2400 * (1 + 0.08)⁽⁵⁾
Future Value = $2400 * (1.08)⁵
Future Value = $2400 * 1.46933
Future Value = $3526.40
So, after five years, the initial deposit will grow to $3526.40.
Now, let's calculate the future value of the additional deposit of $1000 over the last eight years at an interest rate of 5.5% compounded annually.
Future Value = $1000 * (1 + 0.055)⁸
Future Value = $1000 * (1.055)⁸
Future Value = $1000 * 1.50423
Future Value = $1504.23
So, after eight years, the additional deposit will grow to $1504.23.
Now, let's add the two amounts together to find the total amount in the account today:
Total Amount = $3526.40 + $1504.23
Total Amount = $5030.63
So, the total amount money after thirteen years of saving will be $5030.63

Suppose there are n students in a row. We want to compute the number of ways to select 2 non-adjacent students. (Assume that the selected students are interchangeable: i.e., selecting students i and j is the same as selecting students j and i.) For both parts to this problem, you must explain why your answer is correct: it is not sucient to compute a few values directly and look for a pattern.
(a) Write a recurrence relation describing the number of ways to select 2 non-adjacent students.
(b) Repeat part a, but now suppose the students are in a circle (hint: it might help to label the students 1, ... n, even though they are in a circle without a `start' or `end').
Answers
To calculate the number of ways to select 2 non-adjacent students, we can use recurrence relations for both linear and circular arrangements. For the linear arrangement, the recurrence relation is determined by considering two cases: selecting the first student and not selecting the first student. For the circular arrangement, we introduce an additional student to simplify the problem and derive a recurrence relation based on whether the additional student is selected or not.
(a) For the linear arrangement, let's consider the number of ways to select 2 non-adjacent students in a row of n students. We can define a recurrence relation as follows:
Let C(n) represent the number of ways to select 2 non-adjacent students in a row of n students.
If the first student is selected, then the second student cannot be selected, so we are left with n-2 remaining students. The number of ways to select 2 non-adjacent students in this case is C(n-2).
If the first student is not selected, then we have n-1 remaining students. The number of ways to select 2 non-adjacent students in this case is C(n-1).
Therefore, the recurrence relation for the linear arrangement is:
C(n) = C(n-1) + C(n-2)
(b) For the circular arrangement, we introduce an additional student to simplify the problem. Let's consider a circle of n+1 students (n original students and 1 additional student). We want to select 2 non-adjacent students in this circle. We can define a recurrence relation as follows:
Let D(n) represent the number of ways to select 2 non-adjacent students in a circle of n+1 students.
If the additional student is selected, then the two non-adjacent students must be selected from the remaining n students. The number of ways to select 2 non-adjacent students in this case is C(n).
If the additional student is not selected, then we are left with n students. The number of ways to select 2 non-adjacent students in this case is D(n-1).
Therefore, the recurrence relation for the circular arrangement is:
D(n) = C(n) + D(n-1)
By applying the recurrence relations, we can calculate the number of ways to select 2 non-adjacent students for both linear and circular arrangements.

Power companies severely trim trees growing near their lines to avoid power failures due to falling limbs in storms. Applying a chemical to slow the growth of the trees is cheaper than trimming, but the chemical kills some of the trees. Suppose that one such chemical would kill 20% of sycamore trees. The power company tests the chemical on 250 sycamores. Consider these an SRS from the population of all sycamore trees. What is the probability that 24% or more of the trees in the sample are killed? Step #2: Calculate the mean and standard deviation of the sampling distribution. Use appropriate notation.

Answers
the mean of the sampling distribution is 0.20, and the standard deviation is approximately 0.0253.
To calculate the mean and standard deviation of the sampling distribution, we need to use the following formulas:
Mean of the Sampling Distribution (μ):
μ = p
Standard Deviation of the Sampling Distribution (σ):
σ = √[(p(1 - p)) / n]
where p is the probability of an event (in this case, the probability of a tree being killed), and n is the sample size.
Given that the chemical kills 20% of sycamore trees, we have p = 0.20. The sample size is 250, so n = 250.
Now let's calculate the mean and standard deviation:
Mean of the Sampling Distribution:
μ = p = 0.20
Standard Deviation of the Sampling Distribution:
σ = √[(p(1 - p)) / n]
= √[(0.20(1 - 0.20)) / 250]
= √[(0.16) / 250]
≈ √[0.00064]
≈ 0.0253

The side lengths are 8 inches and 10 inches.
Step-by-step explanation:
Let l be the length and w be the width. w = l - 2.
We then have:
\(l(l - 2) = 80\)
\( {l}^{2} - 2l = 80\)
\( {l}^{2} - 2l - 80 = 0\)
