As the number of cookies eaten increases, the calories consumed increases.
As the number of cookies eaten decreases, the calories consumed increases.

Answers

Answer: As the number of cookies eaten increases, the calories consumed increases.

This is because the number of cookies and calories consumed have a directly proportional relationship, meaning that if one value increases, so does the other.

Answer:

As the number of cookies eaten increases, the calories consumed increases.

Step-by-step explanation:

As we can see in the graphic with more cookies we have more calories. Because for 1 cookie we have 50 calories and for 5 cookies we have 200 calories.

Then as the number of cookies increases, the calories consumed increases.

Answers

Final answer:

To solve the proportion v/8 = 13/11, cross-multiply and solve for v. The value of v is approximately 9.5.

Explanation:

To solve the proportion v/8 = 13/11, we can cross-multiply and solve for v. Cross-multiplying gives us v * 11 = 8 * 13. Simplifying, we have 11v = 104. Dividing both sides by 11, we find that v = 104/11. Rounding to the nearest tenth, v ~ 9.5.

what number is 26.8% of 67.5?
and
325% of what is 78.65?

Answers

Well this is easy, just take the percentage as an actual number and just multiply
26.8% as a number is 0.268 (if you don't know how I got this, just divide that percentage by 100, and a 1.00 is equal to a 100%) and 0.268 * 67.5 is 18.09.
(You can round that)
Now 325% as a number is 3.25 (it's bigger than 100% so its increasing)
3.25 * 78.65 is 255.6125.

1. We assume, that the number 78.65 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 78.65 is 100%, so we can write it down as 78.65=100%.
4. We know, that x is 325% of the output value, so we can write it down as x=325%.
5. Now we have two simple equations:
1) 78.65=100%
2) x=325%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
78.65/x=100%/325%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 325% of 78.65

78.65/x=100/325
(78.65/x)*x=(100/325)*x - we multiply both sides of the equation by x
78.65=0.307692307692*x - we divide both sides of the equation by (0.307692307692) to get x
78.65/0.307692307692=x
255.6125=x
x=255.6125

now we have:
325% of 78.65=255.6125
1. We assume, that the number 67.5 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 67.5 is 100%, so we can write it down as 67.5=100%.
4. We know, that x is 26.8% of the output value, so we can write it down as x=26.8%.
5. Now we have two simple equations:
1) 67.5=100%
2) x=26.8%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
67.5/x=100%/26.8%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 26.8% of 67.5

67.5/x=100/26.8
(67.5/x)*x=(100/26.8)*x - we multiply both sides of the equation by x
67.5=3.73134328358*x - we divide both sides of the equation by (3.73134328358) to get x
67.5/3.73134328358=x
18.09=x
x=18.09

now we have:
26.8% of 67.5=18.09.

What are the x-intercepts of the graph of the function f(x) = x2 + 5x − 36?

Answers

Answer:

x intercepts are (4,0) and (-9,0)

Step-by-step explanation:

The given function graphed f(x) = x² + 5x -36 and we have to find the x-intercepts.

Since x intercepts means points on x-axis which will have y-coordinates as zero.

so f(x) = x² + 5x - 36 = 0

x² + 9x - 4x - 36 = 0

x(x+9) - 4(x-9) = 0

(x-4)=0 ⇒ x = 4

or ( x+9) = 0 ⇒ x = (-9)

Therefore, x intercepts are (4,0) and (-9,0)

Considering the definition of function quadratic and roots, the roots or x-intercepts of the graph of the function f(x) = x² + 5x − 36 are 4 and -9.

Function quadratic

The function f(x) = ax² + bx + c

with a, b, c real numbers and a ≠ 0, is a function quadratic expressed in its polynomial form (It is so called because the function is expressed by a polynomial).

Definition of roots

The roots are those values of x for which the expression is 0, so it graphically cuts the x-axis.

This can be solved by:

[tex]x1, x2=\frac{-b+-\sqrt{b^{2} -4ac} }{2a}[/tex]

x-intercepts of f(x) = x² + 5x − 36

In this case you know that a=1, b= 5 and c= -36. So the roots can be determined as:

[tex]x1=\frac{-5+\sqrt{5^{2} -4x1x(-36)} }{2x1}[/tex]

[tex]x1=\frac{-5+\sqrt{25 +144} }{2}[/tex]

[tex]x1=\frac{-5+\sqrt{169} }{2}[/tex]

[tex]x1=\frac{-5+13}{2}[/tex]

[tex]x1=\frac{8}{2}[/tex]

x1= 4

and

[tex]x2=\frac{-5-\sqrt{5^{2} -4x1x(-36)} }{2x1}[/tex]

[tex]x2=\frac{-5-\sqrt{25 +144} }{2}[/tex]

[tex]x2=\frac{-5-\sqrt{169} }{2}[/tex]

[tex]x2=\frac{-5-13 }{2}[/tex]

[tex]x2=\frac{-18 }{2}[/tex]

x2= -9

Finally, the roots or x-intercepts of the graph of the function f(x) = x² + 5x − 36 are 4 and -9.

3(n + 11) + -5n = -2(n + -12) + 9
Reorder the terms:
3(11 + n) + -5n = -2(n + -12) + 9
(11 * 3 + n * 3) + -5n = -2(n + -12) + 9
(33 + 3n) + -5n = -2(n + -12) + 9
Combine like terms: 3n + -5n = -2n
33 + -2n = -2(n + -12) + 9
Reorder the terms:
33 + -2n = -2(-12 + n) + 9
33 + -2n = (-12 * -2 + n * -2) + 9
33 + -2n = (24 + -2n) + 9
Reorder the terms:
33 + -2n = 24 + 9 + -2n

Solving
0 = 0
Couldn't find a variable to solve for.
This equation is an identity, all real numbers are solutions.

Final answer:

The given equation simplifies to -2n + 33 = -2n + 33, where both sides are equal, hence 'n' can be any real number. Thus the equation has infinitely many solutions.

Explanation:

This question pertains to solving a linear equation. The given equation is 3(n+11)-5n=-2(n-12)+9.

Let's solve this step by step:

First distribute 3 and -2 in the brackets (Order of Operations - BIDMAS/BODMAS). This will result in: 3n+33-5n = -2n + 24 + 9.Combine like terms on both sides of the equation to obtain: -2n + 33 = -2n + 33.Lastly you can see that both sides of the equation are equal, this means that n can be any real number.

This indicates that we have infinitely many solutions because any value of 'n' satisfies this equation.

What is P(0.6 ≤ z ≤ 2.12)?

Answers

You have to look up in your Z score table.

P( 0.6≤ z≤ 2012) is the probability or area (of the bell shaped curve) between the value of z = 2.212 & z = 0.6.

To that end for z₁ = 2.12 you find an area = 0.9830 and
for z₂ = 0.6 you find an area = 0.7257

Subtract those values z₁ - z₂ = 0.9830 - 0.7257 = 0.2573

and P( 0.6≤ z≤ 2012) = 0.2573 (0r 25.73%)

The value of P(0.6 ≤ z ≤ 2.12) is, 26%

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

To find the value of P(0.6 ≤ z ≤ 2.12).

Now, We can simplify as;

P(0.6 ≤ z ≤ 2.12) = P( z ≤ 2.12) - P(z < 0.6)

So, From the Cumulative Standardized Normal Distribution table,

P( z ≤ 2.12) = 0.9830

P(z < 0.6) = 0.7257

Hence, We get;

P(0.6 ≤ z ≤ 2.12) = P( z ≤ 2.12) - P(z < 0.6)

P(0.6 ≤ z ≤ 2.12) = 0.9830 - 0.7257

P(0.6 ≤ z ≤ 2.12) = 0.2573

P(0.6 ≤ z ≤ 2.12) = 0.26

P(0.6 ≤ z ≤ 2.12) = 26%
