The choice that is the total amount for the 3 items is C. $98.97.

The amount of money that Kayla have left after the purchase is A. $11.03.

From the information, Kayla saves $110 to purchase a new outfit. She decides to buy a skirt for $29.65, a sweater for $38.32, and a purse for $31.00.

The cost of the items will be:

= Skirt + Sweater + Purse

= $29.65 - $38.32 + $31.00

= $98.97

The amount of money that Kayla have left after the purchase is:

= $110 - $98.97

= $11.03

The interest rate on this loan will be 5%.

Given that Eileen takes a student loan of 10,000 with simple interest to pay back after 10 years. If the estimated payment is 22,000.

The interest on the loan will be:

= $22000 - $11000

= $11000

The interest rate on this loan will be:

Rate = Interest / Principal × Time

Rate = 11000 / (22000 × 10)

Rate = 11000 / 220000

Step-by-step explanation:

        To write an algebraic expression that represents this situation, we need to know that a quotient will involve division.

        We will write the quotient of 5 and a number, k. also written as 5 divided by k, as;

       [tex]\displaystyle \frac{5}{k}[/tex]

        You can read more about writing algebraic expressions involving division here: https://brainly.com/question/17552845

The algebraic expression is - [tex]\frac{5}{k}[/tex]

If one number is divided by another number, the answer obtained is called the quotient.

In mathematics, a number that divides another number is called a divisor.

The number which is to be divided by the divisor is called a dividend.

In arithmetic, if we divide one integer by another, the 'leftover' portion is called the remainder.

In this case, 5 is the dividend, and k is the divisor, which is representing an unknown number.

We can not get an actual number, but we can use an algebraic equation to express the quotient as follows:

When a die is loaded so that the probability of one side appears twice as often as the other five, the number "1" will be the most frequent result when the die is rolled.

When a die is loaded so that one side appears twice as often as the other five, the number that comes up most often when the die is rolled is "1". This is because the loaded die has an unequal probability of rolling each number, with one side being twice as likely to come up as any of the other five sides. This means that the chances of rolling this particular number are twice as great as the chances of rolling any of the other five numbers. For this reason, the number "1" will be the most frequent result when the die is rolled.The probability of rolling the number "1" is 2/7, while the probability of rolling any of the other five numbers is 1/7. Therefore, the number "1" is twice as likely to come up as any of the other five numbers when the die is rolled.

All rectangles are squares. False! A square has ALL sides equal, but a rectangle only has opposite sides equal. All trapezoids have only one pair of parallel sides.

An equation in algebra is a condition on a variable. Only for a certain value of the variable does it satisfy. This indicates that the equation 2x - 5 = 13 can only be met when x = 9. Polynomial equations and linear equations are two significant kinds of equations that are taken into account in algebra. One-variable polynomial equations can be expressed as P(x) = 0, where P is a polynomial and ax + b = 0 is the standard form for linear equations. Here, the variables a and b are used.

Answer: 16 hours

Step-by-step explanation:

       We will write a system of equations to help us solve. Let x be equal to the number of hours worked at the college bookstore, and y be equal to the number of hours worked at Papa Gino's.

       First, we will write an equation for the money earned. Then, we will write one for the hours worked.

8.25x + 9.25y = 247

x + y = 28

       Now, we will will substitute the second equation into the first and solve for the hours worked at Papa Gino's last week, equal to y.

x + y = 28 ➜ x = -y + 28

8.25x + 9.25y = 247

8.25(-y + 28) + 9.25y = 247

-8.25y + 231 + 9.25y = 247

y + 231 = 247

y = 16

To find the amount of the down payment, we need to multiply the cost of the home by the down payment percentage: $90,000 * 8.8% = $7,920.

This means that the total amount that will need to be borrowed from the bank is $90,000 - $7,920 = $82,080.

The mortgage amount will be $82,080. This is the amount that will need to be borrowed from the bank after the down payment of $7,920 is paid. The down payment is calculated by multiplying the cost of the home by the required down payment percentage: $90,000 * 8.8% = $7,920. The mortgage amount is then calculated by subtracting the down payment from the cost of the home: $90,000 - $7,920 = $82,080.

Positive coefficients indicate that the event is more likely to occur at that predictor level than it is at the reference level for the factor.

Positive coefficients indicate that the event has a higher probability of happening at the reference level than at the predictor level.

The correlation coefficient (r2) is a statistic that expresses how closely two variables' movements are related to one another.

To determine the linear relationship between two variables, the Pearson product-moment correlation, the most popular correlation coefficient, is used.

However, this correlation value might not necessarily be a reliable indicator of reliance in a non-linear connection.

They are denoted with a symbol called a partial derivative operator, which is a curved d with a line over it. Partial derivatives are used to calculate derivatives in multivariable functions and to find the maximum or minimum points of a function. Partial derivatives can also be used to analyze the behavior of functions near a point, or to solve equations involving multiple variables.
