What is the probability of picking an odd number and then picking an odd number?

The amount in the new account (future value) after 7 years will be D. $3,207.40.

The future value of the investment is determined in two stages.

The first stage compounds the present investment semiannually at 2.5%.

Using the determined future value of the first stage, we can determine the second stage's future value.

To determine the future values, we deploy an online finance calculator.

N (# of periods) = 24 semiannual periods (12 years x 2)

I/Y (Interest per year) = 2.5%

PV (Present Value) = $1,800

PMT (Periodic Payment) = $0

Results:

Future Value (FV) = $2,425.23

Total Interest = $625.23

N (# of periods) = 84 months (7 years x 12)

I/Y (Interest per year) = 4%

PV (Present Value) = $2,425.23

PMT (Periodic Payment) = $0

Results:

Future Value (FV) = $3,207.40

Total Interest = $782.17

The y-coordinate for the solution to the system of equations is -3.

What is a system of equations?

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations. The intersection of two lines represents the system of equations' solution.

Given system of equations are,

6x + 11y = -3

4x + y = 17

To solve these equations, we must first remove x or y terms.

To do this we must make the removing term's coefficients the same.

In this case, let's remove y.

We are multiplying the second equation by 11. Then,

6x + 11y = -3

44x + 11y = 187

Now we will subtract the second equation from the first.

- 38x  = -190

x = 5

Now to find y, substitute x in any one of the equations.

6 * 5 + 11y = -3

11y = -33

y = -3

Hence the y-coordinate for the solution to the system of equations is -3.

Sum of coordinates, S + T = (9 , -7)

A coordinate is an address, which helps to locate a point in space. For a two-dimensional space, the coordinates of a point are (x, y). Here let us take note of these two important terms.

Abscissa: It is the x value in the point (x, y), and is the distance of this point along the x-axis, from the origin

Ordinate:  It is the y value in the point (x, y)., and is the perpendicular distance of the point from the x-axis, which is parallel to the y-axis.

Given,

S = (4 , -6)

T = (5 , -1)

S + T = (4 , -6) + (5 , -1)

        = (4 + 5 , -6 + -1)

        = (9 , -7)

Hence, S + T = (9 , -7) is sum of coordinates of point S and T

There are 105 odd numbers with a middle digit of 5 between 40000 and 69999 with no repeating digits.

We must first take into account the limitations of the issue in order to determine this.

∴,

There are three options for the first digit: 4, 5, and 6.

There are five options for the units digit: 1, 3, 5, 7, and 9.

There are seven possible outcomes for the remaining digits: 0, 2, 4, 6, 7, 8, and 9.

According to the multiplication principle, the total number of numbers having the needed qualities is:

The area of the region bounded by the lines y = 3x - 6 and y = -2x + 8 between the x-axis is 12/5 units.

We can find the intersection point between these two lines;

y = 3x - 6

y = -2x + 8

Set these two equations equal to each other.

3x - 6 = -2x + 8

5x - 6 = 8

Add 6 to both sides of the equation.

5x = 14

Divide both sides of the equation by 5.

x = 14/5  

Find the y-value where these points intersect by plugging this x-value back into either equation.

y = 3(14/5) - 6

y = 42/5 - 6

Multiply 6 by (5/5) to get common denominators.

y = 42/5 - 30/5  

Subtract and simplify.

y = 12/5

These two lines intersect at the point 12/5. This is the height of the triangle formed by these two lines and the x-axis.

Now let's find the roots of these equations (where they touch the x-axis) so we can determine the base of the triangle.

Set both equations equal to 0.

(I) 0 = 3x - 6  

Add 6 both sides of the equation.

6 = 3x

x = 2  

Set the second equation equal to 0.

(II) 0 = -2x + 8

Add 2x to both sides of the equation.

2x = 8

x = 4

The base of the triangle is from (2,0) to (4,0), making it a length of 2 units.

The height of the triangle is 12/5 units.

Formula for the Area of a Triangle:

A = 1/2bh

Substitute 2 for b and 14/5 for h.

A dot plot is a graphical representation of data that shows the frequency of each data value on a number line by plotting dots above the values. A box plot is a graphical representation of data that depicts data distribution using five key values: minimum, first quartile, median, third quartile, and maximum.

The box plot in this case depicts the distribution of points awarded to dance teams in a competition. The minimum value is zero, the first quartile is fifty, the median is seventy, the third quartile is ninety, and the maximum value is one hundred.

"dot plot titled Dance Competition Points with Points on the x axis and Number of Teams on the y axis with 2 dots over 50, 1 dot over 70, 2 dots over 90, 1 dot over 100," is the dot plot that best represents the box plot data. This dot plot accurately reflects the data distribution in the box plot.

It shows two dots over 50 (representing two teams), one dot over 70 (representing one team), two dots over 90 (representing two teams), and one dot over 100 (representing one team) (representing 1 team). These values correspond to the box plot values and accurately represent the data distribution.

The total value of Mr. Liling's shares at the end of 2016 was $1388.50.

The value of a share, also known as the stock price, represents the price per unit of ownership in a company. It is determined by supply and demand for the stock in the stock market and can fluctuate based on a variety of factors such as the company's financial performance, industry trends, and overall market conditions.

At the beginning of 2016, Mr. Liling bought 10 shares of stock in QIZ Software for $198.58 per share, so the total cost was 10 * $198.58 = $1985.80.

In 2016, the stock price of QIZ Software changed by -$59.73, so the value of Mr. Liling's shares at the end of 2016 was $1985.80 - 10 * $59.73 = $1985.80 - $597.30 = $1388.50.

An equivalent expression  of x² - 8x + 5 is  (x - 4)² - 11

To convert this quadratic expression x² - 8x + 5 into the form (x - a)² - b we will use completing the square method.

Comparing expression  x² - 8x + 5 with ax² + bx + c we get,

a = 1, b = -8 and c = 5

First we find the value of the expression (b/2a)² is:

(b/2a)²

= [-8/(2 × 1)]²

= (-8/2)²

= (-4)²

= 16

Now, we add and subtract the value of the term (b/2a)² in the expression  x² - 8x + 5

So the expression  x² - 8x + 5 becomes,

x² - 8x + 5

= x² - 8x + 5 + 16 - 16        

= x² - 8x  + 16 + 5 - 16       ......(commutative property of addition)

= (x - 4)² - 11                      ......(since (x - 4)² = x² - 8x  + 16)

Therefore, the required expression is:  (x - 4)² - 11

Hi there, here's your answer:

Given:

Weight limit for the lift = 1000kg

Mean weight of 10 people = 70kg

Therefore, the total weight of 10 people inside the lift is 70 × 10 = 700kg.

Now, remaining weight that can fit in the lift is 1000 - 700 = 300kg.

Assuming the mean weight of the people who get inside the lift is constant, we find the closest number of people who can get inside the lift to be:

300 ÷ 70 = 4.285

Answer:

The function displayed in the table is best described as an Exponential Decay Function.

Step-by-step explanation:

            First, the main difference between a linear and an exponential function is the shape of its graph, as well as the presence of either a constant ratio or a constant rate of change.

            Linear functions are functions with a base function of  [tex]f(x)=mx+b[/tex], which has a constant rate of change ([tex]m[/tex]), and the shape of its graph will be a straight line.

            Exponential functions on the other hand use the base function [tex]f(x)=a^x[/tex], where [tex]a[/tex] is the constant ratio of the function, and its graph is curved and has a horizontal asymptote that the graph will approach but never touch as it either increases or decreases to positive or negative infinity respectively.

            The function in the problem gives you four points that are on its graph: (-2, 540), (-1, 270), (0, 135), and (1, 67.5). Using these points, you can determine whether it is a linear or exponential function. You can tell that when the x-value increases by 1, the f(x) value is divided by 2, or multiplied by [tex]\frac{1}{2}[/tex]. Since there is a constant ratio instead of a constant rate of change in the function, you would know that the function in the table is an exponential function. Since the function is also constantly decreasing, the function would be best described as an Exponential Decay Function.
