The value of x is 10.

What is Mean ?

Mean is the average value of the data, It depicts the central tendency of the data.

The numbers are 4 ,3,3,x

The Mean of the data is 5

The Mean = ( Sum of Data) / ( Number of Data)

Mean = (4+3+3+x ) / 4

5 = (10+x)/4

20 = 10+x

x = 10

Therefore, the value of x is 10.

Answer:

4250

Step-by-step explanation:

Anything under this would round down to 4200

To find the maximum height, we must find the x value at which the maximum height occurs.

The maximum height occurs at x = 0 because that is where y is the largest.

When we plug x= 0 into the function that is given in the question, we get 630 ft.

Answer:

x = 6

Step-by-step explanation:

[tex]\sqrt{5x - 7}[/tex] = [tex]\sqrt{3x +5}[/tex] ( square both sides to clear the radicals )

5x - 7 = 3x + 5 ( subtract 3x from both sides )

2x - 7 = 5 ( add 7 to both sides )

2x = 12 ( divide both sides by 2 )

x = 6

Answer: No solution

Step-by-step explanation:

-3x+3y=4

-x+y=3

We will rewrite the first equation and then substitute it into the second equation since we are solving by substitution.

Rewriting

-3x + 3y = 4

3y = 4 + 3x

y = [tex]\frac{4}{3}[/tex] + x

Substituting

-x + y = 3

-x + ([tex]\frac{4}{3}[/tex] + x) = 3

-x + [tex]\frac{4}{3}[/tex] + x = 3

[tex]\frac{4}{3}[/tex]  = 3

Hmmm, this doesn't look right, does it? This means there is no solution.

Answer:

6 x a number - 9 = factored

In this case, since the number is not declared as a specific number, this is the key to us factoring.

Like the number could be 6. ↓

Factoring:

[tex]6*6-9=27\\6*3-9=9\\6*9-9=45[/tex]

bonus even factor:

[tex]6*2-9=3[/tex]

These are factors and Least common multiples of 6 and 9.

Because 9 and 3 show up during half of the problem, and these are related to 6 and 9, the parents, we could measure this on a mathematical scale that this proves the factors correct.

There are other ways to factor this. See comments.

Based on the residual plot, the linear model is not appropriate because  the residuals are relatively large.

A residual plot is a graph that shows the residual values on the y-axis and fitted values on the x-axis. The aim of a residual plot is to check if the residual are consistent with random error.  When the residuals center on zero, it means that the model’s predictions are correct on average. If this is not the case, the model's predictions are not correct.

Answer:

h > 2

Step-by-step explanation:

It may look hard, but it is not really.

1. Solve

Here we have the equation 5+h>7.

All we have to do to find h is to subtract 5 from both sides.

5+h>7

-5     -5

When you subtract 5 from both sides, you get

5 - 5 = 0

7 - 5 = 2

All is left is 0+h>2, or h > 2.

2. Substitute

To make sure, (I do this but you can if you want to) I will substitute.

The values of h have to be greater than 2. So, Let's substitute 3.

5 + h > 7 --> 5 + 3 > 7

It's simple math.

5+3=8

8>7

Now, also to confirm, let's try a value less than 2, 1.

5 + h > 7

5 + 1 > 7

6 > 7 is not true, so it is confirmed that anything less than 2 is not true and anything greater is true.

Hence, h > 2

Answer:

g(f(-4)) = -8

f(g(x)) = 13-10x

Step-by-step explanation:

g(f(-4)):

Plug in the equation f(x) into the variable x of g(x), we have:

[tex](gof)= 5(7-2x)-3[/tex]

Plug in x = -4 and the answer is -8

f(g(x)):
Plug in the equation g(x) into the variable x of f(x), we have:

[tex]7-2(5x-3) = 7-10x+6 = 13-10x[/tex]

The greatest common factor between the expressions is 6v.

We have the expressions:

We can see that the smallest power of "v" is 1, and it appears on the second expression, so the greatest common factor will be a number times v.

To get the number, we need to find the greatest common factor between the 3 coefficients.

12, 30, and 42.

Rewriting these 3 numbers we can see that:

12 = 2*2*3

30 = 2*3*5

42 = 2*3*7

In all the cases we can see that the factor 2*3 appears, so that is the greatest common factor between the coefficients.

So we can conclude that the greatest common factor between the expressions is:

2*3*v = 6v

And we can rewrite:

The possible line of best fit is given by y = -0.5x + 10

A linear equation is in the form:

y = mx + b

Where y, x are variables, m is the rate of change and b is the y intercept.

Let y represent the students still participating in the final round while x represent the number of spelling words attempted.

Since the line of best fit has a negative, linear association, this means that the slope is negative. A possible linear function is:

y = -0.5x + 10

The possible line of best fit is given by y = -0.5x + 10

Given -

↠ the length of a rectangle is 11 m less than three times the width (let the width be x then length = 3x - 11)

↠the area of the rectangle is 42 m².

To find -

the dimensions of the rectangle.

Solution -

As we know,

area of rectangle = length × width

➟ 42 = (3x - 11) x

➟ 42 = 3x² - 11x

➟ 3x² - 11x - 42 = 0

now splitting the middle term to find the value of x,

➟ 3x² - (18 - 7)x - 42 = 0

➟ 3x² - 18x +7x - 42 = 0

➟ 3x (x- 6) +7(x - 6) = 0

➟ (3x + 7)(x - 6) = 0

➟ x = -7/3, 6

➟ x = 6

We will take the value of x as 6 because the value of dimensions can never be in negative.

Hence, length = 3 × 6 - 11 = 7 cm and width = 6 cm

[tex]y = 2\sqrt{10}[/tex]

Step-by-step explanation:

In left small right triangle: we have the square of left side = 5^2 + y^2 = 25 + y^2

In right small right triangle: we have the square of right side = 8^2 + y^2 = 64 + y^2

In the large right triangle, we have (25 + y^2) + (64 + y^2) = (5 + 8)^2

89 + 2y^2 = 13^2 = 169

2y^2 = 169 - 89 = 80

y = 80/2 = 40

so

[tex]y=\sqrt{40} = 2\sqrt{10}[/tex]
