Step-by-step explanation:

x = -2

y = -3

= x² - y²

= (-2)² - (-3)²

= 4 - 9

= -5

If Cherri brought $2100 computer on an installment plan and made $400 down payment and monthly payment for $79. 50 for the next two years, then the interest amount is $208 .

the cost of the computer is = $2100 ;

the amount paid as down payment is = $400 ;

the amount that will be paid in monthly installment is = $79.50 ;

the time for the loan is = 24 months ;

So , the amount paid as installment is 24 months is = \(24 \times79.50\)

= $1908 .

So , the total amount paid by Cherri with installment plan is = \(\$1908+\$400\)

= $2308 .

So , the interest amount paid is = \(\$2308-\$2100\)

= $208 .

Therefore , Cherri will pay $208 as interest .

Step-by-step explanation:

you solve it and see it's easy know first try I will do it

The researcher needs to use the critical value of t = 2.602 for constructing the 99% confidence interval around the mean.

To determine the critical value (t or z) for constructing a confidence interval, we need to consider two factors: the sample size and the desired level of confidence.

In this case, the researcher has 17 subjects and wants to construct a 99% confidence interval around a mean. The critical value depends on the distribution being used (t-distribution or standard normal distribution) and the degrees of freedom.

For small sample sizes (typically less than 30) or when the population standard deviation is unknown, the t-distribution is used. The degrees of freedom for the t-distribution are calculated as n - 1, where n is the sample size. In this case, the degrees of freedom would be 17 - 1 = 16.

To find the critical value for a 99% confidence interval using the t-distribution, we consult a t-table or use statistical software. Looking up the value for a 99% confidence level with 16 degrees of freedom, we find that the critical value is approximately 2.602.

Therefore, the researcher needs to use the critical value of t = 2.602 for constructing the 99% confidence interval around the mean.

It's important to note that if the sample size is large (typically greater than 30) and the population standard deviation is known, the standard normal distribution (z-distribution) can be used instead of the t-distribution. In that case, the critical value would be obtained directly from the standard normal distribution table or using the corresponding quantile function in statistical software.

Answer:

Last option

Step-by-step explanation:

Step 1: Write out equation

x² + 8x - 10 = 0

Step 2: Add 10 to both sides

x² + 8x = 10

Step 3: Complete the Square

x² + 8x + 16 = 10 + 16

(x + 4)² = 26

Step 4: Square root both sides

x + 4 = ±√26

Step 5: Subtract 4 on both sides

x = -4 ± √26

The chi-square test, a statistical method, is used to compare actual results with forecasts. This test's objective is to determine whether a disparity between observed and anticipated data is due to chance or a correlation between the variables under study. Thus, using a chi-square test is a fantastic alternative for better understanding and interpreting the relationship between our two category variables.

Zero, a positive natural number, or a negative integer denoted by a minus sign are all examples of integers. The inverse additives of the equivalent positive numbers are the negative numbers. The set of integers is frequently represented in mathematical notation by the boldface Z or blackboard bold mathbb Z.

The outcome of dividing one integer by another is the quotient. The amount that is left over after dividing one number by another is known as the remainder.

As an illustration, if we divide 14 by 3, the result is a quotient of 4 and a residual of 2. This may be written as: 14 / 3 = 4 +2.

Another way to write this is 14 = 3 x 4 + 2.

The remainder is 2, and the quotient is 4.

6. Given statement: Show that if a, b, c, and d are integers, where a + 0, such that a | c and b | d, then ab | cd.

To prove this statement, we will use the definition of divisibility.

If a | c and b | d, then there exist integers x and y such that c = ax and d = by.

Substituting these expressions into the expression "ab | cd", we get:

ab | axb*y

Since a*b = ab, we can rewrite this expression as:

ab | abxy

Since ab is a factor of abxy, it follows that ab | cd.

Therefore, if a | c and b | d, then ab | cd.

When saving money for a future time when you will be too old to work, the concept of exponential growth becomes crucial.

By investing money, it has the potential to grow exponentially over time due to the compounding effect.

The initial investment, along with any accumulated interest or returns, becomes the new principal, which continues to generate further growth. As time passes, the investment grows faster and faster, propelled by compounding.

This exponential growth is particularly advantageous for long-term retirement planning, as it allows for the accumulation of significant wealth over many years.

Starting early and consistently contributing to investments can harness the power of exponential growth, helping to secure a financially stable future during retirement.

Answer:

\(y = 3x -2\)

Step-by-step explanation:

Step 1) Find two points from the graph to work with

I would personally use the points (0, -2) and (1, 1) as they are the most comfortable to work with from the given graph.

Step 2) Find the slope

A function's slope is given by the formula:  \(m = \frac{y_2 - y_1}{x_2 - x_1}\)
We can now substitute the coordinates of the points we found in Step 1 in the formula to find the function's slope.

\(m = \frac{1 - (-2)}{1 - 0} = \frac 31 = 3\)

Step 3) Find the line's equation

Finally, we can substitute the slope we found in Step 2, as well as one of the points we found in Step 1, into the formula \(y - y_1 = m(x - x_1)\) to find the line's equation.

\(y - 1 = 3(x - 1)\\\to y - 1 = 3x - 3 \text{ / Add 1}\\\to y = 3x -2\)
