Answer:

h ( 5 ) = 36

Step-by-step explanation:

Given function :- h ( x ) = 4 ( x - 2 )²

Also, for h ( 5 ) ... we need to replace x with 5 from the given equation :-

h ( 5 ) = 4 ( 5 - 2 )²

h ( 5 ) = 4 ( 3 )²

h ( 5 ) = 4 ( 9 )

h ( 5 ) = 36

So, h ( 5 ) = 36

Step-by-step explanation:

The most likely correlation coefficient for the set of data shown would be C. 0.19.

The correlation coefficient is a measure of how similar two datasets are acting.

The range of correlation coefficient is [-1, 1]

When the correlation coefficient comes out as -1, it means that both the datasets are negatively oppositely correlated.

One data increases, other data starts decrease in the opposite direction.

If the correlation coefficient comes out as 1, then the values grow exactly similarly, in the same direction.

If the slope of the scatters plot increases from left to your right upwards, the correlation coefficient of the data would be positive.

The scatter plot that is given shows this pattern, therefore, the most likely correlation coefficient of the data set is: C. 0.19.

the first choice 2 ; -2 ; 6 :-6

Step-by-step explanation:

1) method : you can put this values 2 ; -2 ; 6 :-6 you are 0

2) method  you can solve this equation

x^4-40x^2+144=0

let : x² = t   and t ≥ 0

t² -40t +144 = 0

Δ = b²- 4ac    a= 1           b = - 40         c = 144

Δ =(-40)²- 4(1)(144= 1600 -576 = 1024=32²

t1 = (40+32)/2 = 36 = 6²

t1 = (40-32)/2 = 4 = 2²

Step-by-step explanation:

I will assume that you meant:

(1/4)(8x-20)=6x - (x-25) = 5x + 25

If this is correct, let's remove the denominator 4 by multiplying all terms by 4:

(8x - 20) = 4(6x - x + 25), or

8x - 20 = 20x + 100

Consolidating the x terms on the right and the constants on the left, we get:

-120 = 12x, or x = -10

The solution for [tex]\(y\)[/tex] in the equation [tex]\(34x + 14y = 5\)[/tex] is [tex]\(y = -\frac{17x}{7} + \frac{5}{14}\).[/tex]

To solve the equation [tex]\(34x + 14y = 5\)[/tex] for [tex]\(y\)[/tex], we need to isolate [tex]\(y\)[/tex] on one side of the equation. Here's the step-by-step process:

1. **Subtract 34x from both sides:**

[tex]\[ 14y = -34x + 5 \][/tex]

2. **Divide both sides by 14 to solve for y:**

[tex]\[ y = \frac{-34x + 5}{14} \][/tex]

Now, let's simplify the expression by breaking it into two terms:

[tex]\[ y = \frac{-34x}{14} + \frac{5}{14} \][/tex]

Simplify each term:

[tex]\[ y = -\frac{17x}{7} + \frac{5}{14} \][/tex]

So, the solution for [tex]\(y\)[/tex] in terms of [tex]\(x\)[/tex] is:

[tex]\[ y = -\frac{17x}{7} + \frac{5}{14} \][/tex]

This equation represents a line in the xy-plane. The coefficient [tex]\(-\frac{17}{7}\)[/tex] is the slope, indicating the rate of change of [tex]\(y\)[/tex] with respect to [tex]\(x\),[/tex] and [tex]\(\frac{5}{14}\)[/tex]is the y-intercept, representing the point where the line crosses the y-axis.

Mean: Average of the numbers in a set of data.

The mean of a data set is equal to the sum of the set of numbers divided by how many numbers are in the set. If we want to find the mean of the data set shown here, let's begin by adding the numbers.

35 + 40 + 45 + 50 + 55 + 60 + 65 = 350

Now, this will be divided by how many numbers are in the set which is 7.

350 ÷ 7 = 50.

Therefore, the mean of the set of data shown here is 29.2.

Answer:

Problem can not be solved

Step-by-step explanation:

* Lets explain how to solve the problem

- A total of 1000 people attended a benefit concert was held to raise

 money for a children foundation

∴ The number of students and adult is 1000

- Student  ticket cost $2 and an adult ticket cost $3

∴ The cost of the student ticket is $2

∴ The cost of the adult ticket is $3

- The organizer raises a total of $5500

∴ The total money earns fro tickets is $5500

- Assume that the number of students who attended the concert

 is x and the number of adults is y

- There are 1000 students and adults attended the concert

∴ x + y = 1000 ⇒ (1)

- The cost of student ticket is $2

∴ The money earned from students is 2 × x = 2x dollars

- The cost of adult ticket is $3

∴ The money earned from adults is 3 × y = 3y dollars

- The total money earned from students and adults is $5500

∴ 2x + 3y = 5500 ⇒ (2)

* Now lets solve the two equation by elimination method

- Multiply equation (1) by -3 to eliminate y

∴ (-3)x + (-3)y = (-3) × 1000

∴ -3x - 3y = -3000 ⇒ (3)

- Add equations (2) and (3)

∴ -x = 2500

- Multiply both sides by -1

∴ x = -2500

∵ x represents the number of the students and never the number

  of student be negative , then the problem can not be solved

Answer:

5/8

Step-by-step explanation:

4- 9/4 × 3/2 = 4 - (9 *3) / (4*2)

                    = 4 - 27/8

                    = 4*8/8  - 27/8

                   =  32/8 - 27/8

                    = ( 32-27) / 8

                   = 5/8

The correct value of the expression is 0.625.

To evaluate the expression 4 - 9/4 × 3/2, follow these steps:

Start with the multiplication and division from left to right:

Calculate 9 / 4, which equals 2.25.

Then multiply 2.25 by 3/2, which is 1.5. So, 2.25 × 1.5 = 3.375.

Subtract the result from 4: 4 - 3.375 = 0.625.

So, the evaluated value of the expression 4 - 9/4 × 3/2 is 0.625.

Answer:

Step-by-step explanation:

First  let's look at this with just the whole numbers.  Say someone used 2 kg and had 3 left.  it should be pretty simple to see that you started with 5 kg.  It's basically an algebra problem.  if we say x is the starting amount then x-2 = 3.  You could then solve for x=5.  Now, let's dot he same for your actual numbers.  

x - 3/5 = 2 1/4

x = 2 1/4 + 3/5

Now, to add fractions you need to get the same denominators.  we are just really concerned with 1/4 + 3/5.  Now, you need to knwo you can change fractions.  so 1/4 = 2/8 = 3/12 = 4/16 and so on,  You are basically multiplying the numerator and denominator by the same number.  (1*2)/(4*2) = 2/8.  Now, to make both denominators equal you can multiply one fraction by the other denominator.

1/4 + 3/5

(1*5)/(4*5) + (3*4)/(5*4)

5/20 + 12/20 = 17/20.

So now, back tot he main problem, we are adding 2 1/4 + 3/5 = 2 17/20.  so the starting amount was 2 17/20 kg.

There is another way to add fractions but it is more involved and this always works so this is what I always use.  

Ms. How bought a bag of rice that weighs 57/20 or 2 7/20 kg.

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, Ms. How bought a bag of rice for dinner.

Assuming she bought x kg of rice.

She used 3/5 kg of the rice and still had 2 1/4 kg left.

∴ x - 3/5 = 9/4.

x = 3/5 + 9/4.

x = (12 + 45)/20 kg.

x = 57/20 kg.

he can bring up 16.8 approx., but total boxes would be 16.

Step-by-step explanation:

The equation representing the situation is 150 + 50x <= 1000, where x represents the number of boxes of books the delivery person brings up to the office.

To write an equation, we need to represent the information given in the situation. Let's assign a variable, x, to represent the number of boxes of books the delivery person brings up to the office. The weight of the delivery person is fixed at 150 lbs and the weight of each box is 50 lbs. So, the total weight carried by the elevator is 150 + 50x. The equation representing this situation is 150 + 50x ≤ 1000, since the maximum capacity of the elevator is 1000 lbs.

Absolute values are always non-negative, so |-2.24| equals 2.24.

The absolute value of a number is its distance from zero on the number line, ignoring its sign. For -2.24, the distance from zero is 2.24 units.

This concept is useful in various mathematical calculations, such as finding the magnitude of a vector in physics or determining the error in measurements. In practical terms, it allows us to express distances, differences, or deviations without regard to direction. For example, if you are comparing temperatures, the absolute difference between -5°C and 8°C is 13°C, regardless of whether you are measuring an increase or decrease in temperature. This property makes absolute values valuable in many areas of mathematics, science, and everyday life.
