The sum of compound interest on a sum of money is (principal ) Rs 2000.

CI = P*(1+R/100) is the formula for compound interest, which is computed by multiplying the starting principle amount by one and  annual interest rate multiplied by the number of compound periods minus one (T)

CI = A – P

Periodic compounding formula is another name for this formula. In this case, A stands for the updated principle amount or the entire sum of money after the compounding period. P stands for the first or original quantity.

now we have :-

time (annual)=2

time (semi-annual)=4

rate  (annual)= 20

rate (semi-annual=10

difference compound interest =   482

CI(semi-annual)-CI(annual) =482

P*(1+10/100)^(4)  - P*(1+20/100)^(2)=482

P{ (14641/10000) - (36/25)}= 482

P(241/10000)=482

P=(482*10000)/241

P= 20000.

Scatterplots are best for showing the relationship between two interval/ratio variables and indirect or negative relationship between two ratio variables.

Scatterplots are best for showing:

⇒the relationship between two interval/ratio variables

⇒indirect or negative relationship between two ratio variables

Scatterplots display points on a coordinate plane, with one variable plotted on the x-axis and the other variable plotted on the y-axis. This allows us to see the pattern of relationship between the two variables. If there is a positive or negative relationship, we can see if the points tend to increase or decrease as we move from left to right or from bottom to top. If the relationship is indirect, we can see if the points tend to curve in one direction or another.

Scatterplots are not the best visualisation for showing: correlation

frequency of two nominal variables

For showing correlation, a line of best fit (regression line) can be added to a scatterplot, but other visualizations such as a correlation matrix or a heat map are more commonly used.

For showing frequency of two nominal variables, a two-way table or a mosaic plot are better suited, as they can display the count or proportion of cases for each combination of the two nominal variables.

Rounding to the nearest tenth, the area of the playground is 176.7 square feet.

As per the data given in the question,

We have,

The shape of the playground = circular

So, for finding the area of a circle, we can use the formula of finding the area of a circle:

So, the value of the area will be: A = πr^2,

where A is the area and r is the radius.

Since the fence is 47.1 feet long,

we can assume that it is the circumference of the circle and divide it by 2π to find the radius:

47.1 feet / 2π

= 47.1 / (2 * 3.14)

= 7.5 feet

So the radius is 7.5 feet and the area of the playground is:

A = π * 7.5^2

A= 3.14 * 56.25

In order to calculate the new divisor for a 3-for-4 reverse stock split, we must first calculate the new share price for Able. Since 3/4 of the shares are being replaced with just 1/4 of the old shares, the new price for Able will be $111 (3 x $37 = $111).

The divisor is used to calculate the new index value by dividing the sum of the new share prices by the divisor. Therefore, the new divisor will be 1.33 ($111 + $312 + $94 = $517 / 1.33 = $389.28). This is because the new share prices will total $517 and when you divide that by the divisor, the index value will be $389.28.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.

The ratio of the matching sides will remain constant if two triangles are comparable to one another.

Ethan is 1.85 meters tall. At 10 a.m., he measures the length of a tree's shadow to be 28.45 meters. He stands 24.3 meters away from the tree.

Then the height of the tree is given as,

h / 1.85 = 28.45 / (28.45 - 24.3)

h / 1.85 = 28.45 / 4.15

h = 1.85 x 28.45 / 4.15

According to the concept of fraction the value of the quantity at any time t is -4.

A fraction is a mathematical representation of division of two numbers. In this case, we will be using fractions to solve an initial value problem.

The initial value problem is ′=−2,(0)=−4.

This means that the rate of change of the quantity is -2 and its starting value at time 0 is -4.

To solve this problem, we need to find the value of the quantity at some other time.

Here the first step is to find the general solution to the differential equation ′=−2.

This can be done by integrating both sides, which gives us

=> −2.

Integrating, we get

=> −2 + C, where C is an arbitrary constant.

Next, we use the initial value to find the value of C.

We know that when t=0, the value of the quantity is -4, so we can substitute these values into the general solution to get

=> -4 = -2 + C.

Solving for C, we get C = -2.

The derivative of f(z) = ez/(z − 7) is therefore f'(z) = (ez(z - 6))/(z - 7)^2.

The derivative of f(z) = ez/(z − 7) can be calculated using the quotient rule. The quotient rule states that the derivative of the quotient of two functions is equal to the denominator times the derivative of the numerator minus the numerator times the derivative of the denominator, all divided by the denominator squared. Therefore, the derivative of f(z) = ez/(z − 7) is equal to (ez(z - 7) - (ez)(1))/(z - 7)^2. This simplifies to ez/(z - 7)^2. Therefore, the derivative of f(z) = ez/(z − 7) is equal to ez/(z - 7)^2.

For our purposes, we can substitute in g(z) = ez and h(z) = (z − 7). Then, we can calculate the derivatives of each part. The derivative of g(z) is g'(z) = ez, and the derivative of h(z) is h'(z) = 1. Now, we can plug these values into the Quotient Rule and calculate the derivative of the function f(z) = ez/(z − 7).

f'(z) = (ez(z − 7) - ez(1))/(z − 7)^2

f'(z) = (ez(z - 6))/(z - 7)^2

The derivative of f(z) = ez/(z − 7) is therefore f'(z) = (ez(z - 6))/(z - 7)^2.

The slope-intercept equation of the line that best fits the data, with a slope of 5.3333 and a y-intercept of 9.6666.

What is the slope?

The slope of a line represents the change in the dependent variable (y) for a unit change in the independent variable (x). In this case, the slope of the line of best fit represents the average change in the test grade for a one hour increase in studying. To find the slope, you can use the formula:

m = (Σxy - (Σx)(Σy)/n) / (Σx² - (Σx)²/n)

To find the slope-intercept equation of the trend line using the first and last data points, we'll first find the slope (m) of the line. The slope can be found using the formula:

m = (y₂ - y₁) / (x₂ - x₁)

where x₁ and y₁ are the values for the first data point, and x₂ and y₂ are the values for the last data point. In this case, the first data point is (1, 15) and the last data point is (7, 47):

m = (47 - 15) / (7 - 1) = 32 / 6 = 5.3333

Next, we'll use the slope and the first data point to find the y-intercept (b) using the formula:

b = y₁ - m * x₁

b = 15 - 5.3333 * 1 = 15 - 5.3333 = 9.6666

Finally, we'll use the slope and y-intercept to write the slope-intercept equation of the line:

y = mx + b

y = 5.3333x + 9.6666

Hence, the slope-intercept equation of the line that best fits the data, with a slope of 5.3333 and a y-intercept of 9.6666.

The sunflower be after w weeks would be 25 + 0.5 * w inches tall.

Let's say James and Natalie were playing with matchsticks when they had the idea to create number patterns with them. James made the number 4 with four matchsticks. In order to create a pattern with two 4s, Natalie added three extra matchsticks. They understood that they could keep adding three matchsticks each round to make an additional "four" by doing so. They deduced from this that, generally speaking, in order to create a pattern with n number of 4s, you need 4+ 3(n-1) sticks. We refer to 4+ 3(n-1) as an algebraic expression in this case.

To calculate the height of the sunflower after 10 weeks, we can use the formula:

height = starting height + growth rate * time elapsed

where the starting height is 25 inches, the growth rate is 0.5 inches per week, and the time elapsed is 10 weeks.

So the height after 10 weeks would be:

height = 25 + 0.5 * 10 = 25 + 5 = 30 inches

Therefore, the sunflower would be 30 inches tall after 10 weeks.

To calculate the height after w weeks, we can use the same formula:

height = 25 + 0.5 * w

Answer:

Step-by-step explanation:

Part A:

To find the value of the remaining angles, we can use the fact that the sum of the angles in a triangle is 180°.

First, let's find the value of <1. We have:

<4 + <1 + <2 = 180°

4 + <1 + (180° - 5 - 4) = 180°

4 + <1 + 171° = 180°

<1 = 5°

Next, let's find the value of <7. We have:

<7 + <5 + <6 = 180°

<7 + 135° + (180° - 10 - 5) = 180°

<7 + 135° + 165° = 180°

<7 = 0°

Finally, let's find the value of <9. We have:

<9 + <10 + <11 = 180°

<9 + 11° + (180° - 10 - 11) = 180°

<9 + 11° + 159° = 180°

<9 = 0°

Part B:

The angle <4 is supplementary to angle <1, meaning they add up to 180°.

The angle <7 is congruent to angle <5, meaning they have the same measure.

The angle <9 is congruent to angle <10, meaning they have the same measure.
