An algebraic equation can be defined as a mathematical statement in which two expressions are set equal to each other.

It is given that Three-fourths of the total number of different toppings available at the make-your-own sundae shop = 12

The algebraic equation given by Sameer is wrong, the correct equation will be:

Based on the information, the correct information regarding the graph is that C. Quantity demanded decreases as price increase.

The graph shows that for every increase of 100 units of the goods demanded, price reduces by 1 unit.

When 500 units was demanded, the price was at 1. Therefore, if 550 units are demanded, the price will reduce by half, which means the price would drop to 0.5.

The price would drop to 0.5. In this case, the the correct information regarding the graph is that Quantity demanded decreases as price increase.

The expected value of the purchase of a ticket is -$2.95.

To find the expected value of the purchase of a ticket, we need to consider the probability of winning and the amount of money gained or lost.

Given:

The cost of a raffle ticket is $5.

The prize is a camera worth $200.

One hundred tickets are sold.

To calculate the expected value, we multiply the probability of winning by the value gained and subtract the probability of not winning by the cost of the ticket.

Probability of winning:

Since there are 100 tickets sold and only one winner, the probability of winning is 1/100, or 0.01.

Value gained:

If the ticket is a winning ticket, the value gained is $200.

Probability of not winning:

The probability of not winning is 99/100, or 0.99, as there is only one winner out of 100 tickets.

Cost of the ticket:

The cost of a ticket is $5.

Now, let's calculate the expected value:

Expected value = (Probability of winning × Value gained) - (Probability of not winning × Cost of ticket)

= (0.01 × $200) - (0.99 × $5)

= $2 - $4.95

= -$2.95

The expected value of the purchase of a ticket is -$2.95.

This means that, on average, for each raffle ticket purchased, a person can expect to lose approximately $2.95.

It is possible to translate the parent function f(x) = x using various transformations including vertical and horizontal translations. Each transformation will result in
the graph intersecting the x- or y-axis at a different point.

Function is an operation that takes an input, performs some processing on it, and returns a result. It is a set of instructions that performs a specific task. Functions are typically used to perform repetitive tasks, like finding the sum of two numbers, adding two strings together, or finding the maximum of a list of numbers. Functions are essential to programming and can be used to make code more organized, reusable, and efficient.


The function f(x) = x is the parent function for linear equations. This equation is generally used to graph a line with a slope of 1 and a y-intercept of (0, 0). In order to translate this parent function, different transformations are applied to it.

A vertical translation down 4 units would be represented by the equation f(x) = x - 4. This transformation would shift the graph of the parent function down 4 units on the y-axis. This would result in the graph intersecting the y-axis at the point (0, -4).

A horizontal translation right 4 units would be represented by the equation f(x) = x + 4. This transformation would shift the graph of the parent function right 4 units on the x-axis. This would result in the graph intersecting the x-axis at the point (4, 0).

A horizontal translation left 4 units would be represented by the equation f(x) = x - 4. This transformation would shift the graph of the parent function left 4 units on the x-axis. This would result in the graph intersecting the x-axis at the point (-4, 0).

Finally, a vertical translation up 4 units would be represented by the equation f(x) = x + 4. This transformation would shift the graph of the parent function up 4 units on the y-axis. This would result in the graph intersecting the y-axis at the point (0, 4).

In conclusion, it is possible to translate the parent function f(x) = x using various transformations including vertical and horizontal translations. Each transformation will result in the graph intersecting the x- or y-axis at a different point.

Answer:

It is the portion of the cost based on renting a car for d days

Step-by-step explanation:

Given:

Total cost = 15 + 18d

Total cost = fixed cost + variable cost

Fixed cost are cost that do not change.

Fixed cost = base rate = 15

Variable cost changes during production process. The variable cost in the above varies with the number of days (d)

Therefore, 18d is the portion of the cost based on renting a car for d days.

If you rent the car for 1 day

Total cost = 15 + 18d

= 15 + 18(1)

= 15 + 18

Kevin's kick can be considered the best among the four.

To determine the most impressive kick, we can compare the distances and heights achieved by each player.

Andre's kick reached a maximum height of 17 yards and landed 48 yards away from the goal.

Juana's kick followed the path y = -x + 14 - 24, where y represents the height of the ball in yards and x represents the horizontal distance from the goal line. From the graph, we can estimate that her kick landed about 38 yards from the goal and reached a maximum height of 14 yards.

Kevin's kick is shown in the graph, indicating that it landed approximately 19 yards from the goal and had a peak height of 20 yards.

Emiko's kick reached a maximum height of 18 yards and landed approximately 20 yards from the goal.

Considering these measurements, Kevin's kick stands out. It traveled the farthest, landing closest to the goal line, and it achieved the highest height, reaching 20 yards. Consequently, Kevin's kick can be considered the best among the four.

Excluded values are values of x that are not in the domain of the given equation. That is, they are values that make the equation "undefined." In general, those are values that make any of the denominators be zero.

  x +2 = 0   ⇒   x = -2 must be excluded

  x² -4 = (x +2)(x -2)   ⇒   x = -2, 2 must be excluded

The excluded values are -2, 2.

The interest is 16% compounded semi-annually, is Rs. 121,179.10.

To determine how much money needs to be deposited now to provide a payment of Rs. 15,000 at the end of each half year for 10 years, we will use the formula for the present value of an annuity.

Present value of an annuity = (Payment amount x (1 - (1 + r)^-n))/rWhere:r = interest rate per compounding periodn = number of compounding periodsPayment amount = Rs. 15,000n = 10 x 2 = 20 (since there are 2 half years in a year and the payments are made for 10 years)

So, we have:r = 16%/2 = 8% (since the interest is compounded semi-annually)Payment amount = Rs. 15,000Using the above formula, we can calculate the present value of the annuity as follows:

Present value of annuity = (15000 x (1 - (1 + 0.08)^-20))/0.08 = Rs. 121,179.10Therefore, the amount that needs to be deposited now to provide payment of Rs. 15,000 at the end of each half year for 10 years, if the interest is 16% compounded semi-annually, is Rs. 121,179.10.

Answer:

I can tell it's the answer number 5

Answer:

Given a = 14

d = 7

an = 196

a + ( n - 1 ) d = 169

14 + ( n - 1 ) 7 = 169

( n - 1 ) 7 = 182

n - 1 = 26

n = 26 + 1

n = 27

Sum = n / 2 ( a + an )

27 / 2 ( 14 + 196 )

27 ( 105 )

2835

Answer:

2835.

Step-by-step explanation:

The first integer divisible by 7 is 14 and the last one is 196 ( as 7*28) = 196).

We have an Arithmetic series here where each term is increased by 7 to get the next one.

The number of terms (n) = (196 - 14)/ 7 + 1 = 26 + 1 = 27.

The formula for the sum of n terms = (n/2)(a + l) where a = first and l = last term.

So the answer is :

(27/2)( 14 + 196)

= 13.5 * 210

= 2835.
