Answer:

I Need Help On That Too

Step-by-step explanation:

Answer:

8

Step-by-step explanation:

Put the numbers in order from lowest to highest. Add all the numbers together. We will ignore a for this step. You should get 34 when adding it all together. Then if you were to add 8 to that 34 you'd get 42. Divide 42 by the amount of numbers you have which is 7. Your answer is 6. Now to make sure 8 is our value. We want to make sure the median is also 6. to find the median you need to have the numbers in order for lowest to highest and find the number in the middle. Don't forget to add your new number 8 into that order. You should get 6 as the median. Therefore our answer is 8

Marcus is accurate. Jeremy is wrong because he overlooked the negative sign in the equation's initial addend. Since -25 has a greater absolute value than 3, it is obvious that the sum should be negative.

Marcus is correct; the solution is -22.

The simplified expression is given as:

= -(5²)+ 3

= -(25) + 3

= - 22

The right response is this. Marcus saw the bracket or parentheses symbol when he condensed his sentence. This has major significance.

Jeremy scored 28. He squared -5 without noting that it was in a bracket or parenthesis, therefore his response is incorrect.

Consequently, Jeremy calculated this.

= -(5²) + 3

= 25 + 3

= 28

Jeremy gave a false response. He made a computation but failed to see the bracket.

3(d+11)=6(d+33)

simplifing the above equation

3d+33=6d+198

3d-6d=198-33

-3d=165

d= -165/3

d=-55

Answer:

b. 1

Step-by-step explanation:

3d + 33 = 6d + 198

3d - 6d = 198-33

-3d = 165

thus, d = -165/3

The three posts can be given in 4080 ways among 17 students.

It is given that the number of people available to choose the posts from is 17.

There are three posts here- president, vice president, and secretary.

Now, if we choose a candidate for President first, there are 17 students available.

Next, if we select a Vice-President, there are 16 ways to select the vice-president, since one student already is the president.

At, last there are 15 students available to choose the secretary from as two students already hold a post.

Hence, the number of ways to select the President, Vice-President, and Secretary are-

17 X 16 X 15 ways

Therefore we get

A monomial function that has a minimum value is y = 5x^10

In this question, we have been given four monomial functions.

y = 5x^10

y = -4x^11

y = -x^12

y = 6x

we need  to find a monomial function that has a minimum value.

For function y = 5x^10, as x > 0 increases, f(x) increases. And as x < 0 decreases, f(x) increases.

We know that for even, positive monomial function if coefficient > 0 and exponent is even then a monomial has a minimum value.

Therefore, a monomial function that has a minimum value is y = 5x^10

a. The equation that represents the given data is y = 700x + 2,000.

b. The average daily attendance at Disneyland on its 80th anniversary is 58,000.

We are given the data about average daily attendance at Disneyland's anniversary celebrations. At Disneyland's 40th anniversary, the average daily attendance was 30,000 people. On the 60th anniversary, the average daily attendance was 44,000 people. We need to create an equation that would represent y, the average daily attendance, based on x, the number of years after Disneyland opened.

We can write the data in the form of points on the coordinate axes. The coordinates of the points are (40, 30,000) and (60, 44,000). We can use the two-point form to write an equation.

(y - y1) = [(y2 - y1)/(x2 - x1)]*(x - x1)

(y - 30,000) = [(44,000 - 30,000)/(60 - 40)]*(x - 40)

(y - 30,000) = [(14,000)/(20)]*(x - 40)

(y - 30,000) = (700)*(x - 40)

y = 700x - 28,000 + 30,000

y = 700x + 2,000

Now, we need to find out the average daily attendance at Disneyland on its 80th anniversary.

y = 700*80 + 2,000

y = 56,000 + 2,000

y = 58,000

The exact values of the six trigonometric functions for the point (x, y) = (20, 21) are listed below:

sin θ = 21 / 29, cos θ = 20 / 29, tan θ = 21 / 20, cot θ = 20 / 21, sec θ = 29 / 20, csc θ = 29 / 21

Points in rectangular format are points of the form (x, y), where x and y represent the position of the point respect to the origin and along the respective orthogonal axis.

The line segment between the origin and that point represents the hypotenuse of a right triangle. Then, we can determine the six trigonometric functions by using the following formulae:

sin θ = y / √(x² + y²)

cos θ = x / √(x² + y²)

tan θ = y / x

cot θ = x / y

sec θ = √(x² + y²) / x

csc θ = √(x² + y²) / y

If we know that x = 20 and y = 21, then the exact values of the trigonometric functions are:

sin θ = 21 / √(20² + 21²)

sin θ = 21 / 29

cos θ = 20 / √(20² + 21²)

cos θ = 20 / 29

tan θ = 21 / 20

cot θ = 20 / 21

sec θ = √(20² + 21²) / 20

The numbers that add to -5 and multiply to -4 are -5.7015 and 0.7015.

There are two numbers. The addition of the two numbers is -5. The multiplication of the two numbers is -4. We need to find the two numbers. Let the first number and the second number be represented by the variables x and y, respectively. Then, we can write the two following equations.

x + y = -5

x*y = -4

We will substitute the value of y from the first equation into the second equation.

x*(-5 - x) = -4

x*(x + 5) = 4

x² + 5x - 4 = 0

Now, we will use the quadratic formula.

x = [-5 ± √(5² - 4(1)(-4))]/2(1)

x = [-5 ± √(25 + 16)]/2

x = [-5 ± √41]/2

x = [-5 ± 6.403]/2

The values of x are -5.7015 and 0.7015. The corresponding values of y are 0.7015 and -5.705.

A retailer raised a shirt's original price by a certain percentage before lowering it by the same percentage. The price was increased and decreased by 40% as the final cost was 84% of the initial cost.

In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100). A number or ratio that can be expressed as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage therefore refers to a part per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

Here,

Let's say the shirt originally cost Rs 100, and we're adding t% to the price.

The new price of the shirt is therefore 100 + (t/100 * 100) = Rs. 100+t after the initial t% increase.

The price is then reduced by t%.

Cost of a new shirt: (100 + t) - (t/100)

[100+t] = (100+t)

[1-(t/100] = [(100+t)/100]

therefore, the final price is equal to 84% of Rs 100, or Rs 84.

10000 - t^2 = 84.

t^2 = 1600

 t = 40

The price was thus raised and lowered by 40%.

The original price of a shirt was increased by a specific percentage before being decreased by the same percentage by the retailer. As the final price was 84% of the initial price, the price was both increased and decreased by 40%.

Our first step is to divide the four digit number into four places: tens, hundreds, and thousands.

To solve this problem, we must start from the right-hand side and find how many even numbers should be placed where the desired answer can be obtained.

There are a total of [0, 2, 4, 6, and 8] objects

There should only be one digit on one place, since it is the only digit that makes the number divisible by five

There are 1 ways to fill the one's place, so the total number is 1.

It is possible to take any number from the given sets of even numbers in the tens place,

There are five ways to fill one place, so there are five ways to fill it.

Taking a look at the hundreds place,

All numbers can be placed in the hundreds place from the given sets, so all numbers can be taken from the hundreds place.

Therefore, there are five ways to fill the hundreds place.

Taking a look at the thousands,

It is possible to fill thousands of places with 4 numbers from a given set of even numbers.

Therefore, there are four ways to fill the thousands place

The next step is to use the concept of factorial to find the number of ways to make a 4-digit number from even numbers that are divisible by 5.

To fill the respective places, we will multiply all the ways we calculated

= 4 × 5 × 5 × 1

= 100
