A statistical measure known as correlation expresses how closely two variables are related linearly (meaning they change together at a constant rate). It's a typical technique for describing straightforward connections without explicitly stating cause and consequence.

Given:

The positive linear correlation shows a line which is Diagonally rising.

and, The negative linear correlation shows a line which is Diagonally falling.

So, the graph we have no Correlation because it does not any falling and rising line.

Answer:

383 children and 361 adults

Step-by-step explanation:

Let's say there are a adults and c children. Since the total number of people was 744, we can write:

a + c = 744

We also know that children's prices are $1.75 per child and adults' prices are $2 per adult. Since the total is $1392.25, we can write:

1.75c + 2a = 1392.25

Now we have a system of linear equations:

a + c = 744

1.75c + 2a = 1392.25

Multiply the first equation by 2:

2 * (a + c = 744)  ⇒  2a + 2c = 1488

Now subtract the second equation from this one:

    2a + 2c = 1488

-    2a + 1.75c = 1392.25

___________________

    0a + 0.25c = 95.75

c = 383

Plug this in to find a:

a + c = 744

a + 383 = 744

a = 361

There were 383 children and 361 adults.

Lets use some variables:

x = number of adults

y = number of children

744 total people used the public swimming pool and the number adults and children are unknown, so, we can write an equation like:

x + y = 744

Since $2 are for adults, we can write that as 2x. Since $1.75 are for children, we can write that as 1.75y. Since the total price is $1,392.25, that's what the equation should equal. Equation:

2x + 1.75y = 1,392.25

Now, we have a system of equations.

~Rationalize equations

x + y = 744, 2x + 7/4y = 5569/4

~Isolate x for [ x + y = 744 ]

x + y - y = 744 - y

x = 744 - y

~Substitute with x

2(744 - y) + 7/4y = 5569/4

~Isolate y for [ 2(744 - y) + 7/4y = 5569/4 ]

2(744 - y) * 4 + 7/4y * 4 = 5569/4 * 4

8(744 - y) + 7y = 5569

5952 - 8y + 7y = 5569

5952 - y = 5569

5952 - 5952 - y = 5569 - 5952

-y = -383

-y/-1 = -383/-1

y = 383

~Substitute y with 383 in [ x = 744 - y ]

x = 744 - 383

x = 361

Therefore, there are 361 adults and 383 children.

Answer

Step-by-step explanation:

We have been given that you invest $100,000 in an account earning 8% interest compounded annually. We are asked to find the time it will take the amount to reach $300,000.

We will use compound interest formula to solve our given problem.

[tex]A=P(1+\frac{r}{n})^{nt}[/tex], where,

A = Final amount after t years,

P = Principal amount,

r = Annual interest rate in decimal form,

n = Number of times interest is compounded per year,

t = Time in years.  

[tex]8\%=\frac{8}{100}=0.08[/tex]

[tex]300,000=100,000(1+\frac{0.08}{1})^{1\cdot t}[/tex]

[tex]300,000=100,000(1.08)^{t}[/tex]

[tex]\frac{300,000}{100,000}=\frac{100,000(1.08)^{t}}{100,000}[/tex]

[tex]3=(1.08)^{t}[/tex]

[tex](1.08)^{t}=3[/tex]

Let us take natural log on both sides of equation.

[tex]\text{ln}((1.08)^{t})=\text{ln}(3)[/tex]

Using natural log property [tex]\text{ln}(a^b)=b\cdot \text{ln}(a)[/tex], we will get:

[tex]t\cdot \text{ln}(1.08)=\text{ln}(3)[/tex]

[tex]\frac{t\cdot \text{ln}(1.08)}{\text{ln}(1.08)}=\frac{\text{ln}(3)}{\text{ln}(1.08)}[/tex]

[tex]t=\frac{1.0986122886681097}{0.0769610411361283}[/tex]

[tex]t=14.274914586[/tex]

Upon rounding to nearest tenth of year, we will get:

[tex]t\approx 14.3[/tex]

Therefore, it will take approximately 14.3 years until the account holds $300,000.

Perimeter = 160 ft

length = 50 ft

Asked :

Area = ...?

Answer :

Find the width first :

Perimeter = 2 (length + width)

160 = 2 (50 + width)

width = (160 ÷ 2) - 50

width = 80 - 50

width = 30 ft

Now, let's find the Area :

Area = length × width

= 50 × 30

= 1.500 ft²

So, the area of the playground is 1.500 ft²

Answer:

here you go

Step-by-step explanation:

add them all together = 60

+ 40 = 100

4 boxed

40 divided by 4 = 10

add 10 onto each number

red = 21%

silver = 34%

grey = 26%

black = 19%

all of them added together = 100%

The gross margin percentage after packaging costs would be a) 30%.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, Danielle had planned her gift basket to be priced at $50 with a 40% gross margin.

let, The original price be 'x'.

Therefore, $50 is 140% of 'x' which is,

(140/100)×x = 50.

1.4x = 50.

x = 50/1.4.

x = 35.71.

Now, The packaging cost is $3 which makes the cost of the product 38.71.

So, (50/38.71)×100.

= 29% gross margin.

Answer:150.

Step-by-step explanation:

The ratio of similarity between the two trapezoids  is 2:1, which means that the linear dimensions of the larger trapezoid are twice those of the smaller one.

To find the ratio of similarity between two similar trapezoids with areas of 180 [tex]cm^2[/tex] and 45 [tex]cm^2[/tex], we use the principle that the ratio of the areas of similar figures is equal to the square of the ratio of their corresponding linear dimensions. In other words, if the ratio of similarity (scale factor) between the linear dimensions of two similar figures is 'k', then the ratio of their areas is '[tex]k^2[/tex]'.

Let the ratio of similarity be 'k'. Then we have 180/45 = k^2. Simplifying this, we get 4 = [tex]k^2[/tex] and thus, k = 2. This means the linear dimensions of the larger trapezoid are twice those of the smaller one.

Therefore, the ratio of similarity between the two trapezoids is 2:1.

Final answer:

Perpendicular lines on a coordinate plane intersect to form right angles, which are precisely 90°. The slopes of perpendicular lines are negative reciprocals of each other.

Explanation:

When two lines on a coordinate plane are described as being perpendicular, this means they intersect to form right angles, which are angles of 90°. It's important to recognize that perpendicular lines have slopes that are negative reciprocals of each other. For example, if one line has a slope of 2, a line perpendicular to it would have a slope of -1/2. These slopes ensure that the angles formed between the lines are exactly 90 degrees.

In geometry and physics, this concept is further explored with orthogonal vectors, which are two vectors with directions that differ by exactly 90°, synonymous with perpendicular vectors. Their importance lies in various applications, such as breaking down a force into components acting along perpendicular axes.

Answer:

(a)x=100

(b)Maximum Height, h=53 Units

(c)x=200 Units

Step-by-step explanation:

Given the equation which describes the path of the baseball

[tex]h = -0.005x^2 + x + 3[/tex]

(a)Equation of the axis of symmetry

For a quadratic function of the form [tex]y=ax^2+bx+c[/tex], its equation of the axis of symmetry is determined by the equation:

[tex]x=-\dfrac{b}{2a}[/tex]

In the function given: a=–0.005, b=1

Therefore:

[tex]x=-\dfrac{1}{2*-0.005}=\dfrac{1}{0.01}\\\\x=100[/tex]

Equation of the axis of symmetry, x=100

(b)Maximum height reached by the baseball

The maximum height reached by the baseball occurs at the line of symmetry.

Therefore, when x=100

Maximum Height, [tex]h = -0.005(100)^2 + 100 + 3[/tex]

=53 Units

(c)When the height =3 feet, we want to determine the value of x.

[tex]h = -0.005x^2 + x + 3\\3 = -0.005x^2 + x + 3\\-0.005x^2 + x=0\\x(-0.005x + 1)=0\\-0.005x + 1=0\\-0.005x =-1\\$Divide both sides by -0.005\\x=200 Units[/tex]

Final answer:

The equation of the axis of symmetry is x = -100, the maximum height reached by the baseball is 103 feet, and to find the specific distance traveled when caught at 3 feet would require solving the quadratic equation given.

Explanation:

The equation h = –[tex]0.005x^2[/tex]+ x + 3 describes the path of a baseball hit into the outfield, where h is the height and x is the horizontal distance the ball travels.

a. What is the equation of the axis of symmetry?

The equation of the axis of symmetry for a quadratic equation in the form of [tex]ax^2 + bx + c[/tex] is given by x = –b/2a. Hence, for our equation, the axis of symmetry is x = –(1)/(2×–0.005) = –100.

b. What is the maximum height reached by the baseball?

The maximum height can be found by substituting the x-value of the axis of symmetry into the original equation. So, h = –[tex]0.005(100)^2[/tex] + 100 + 3 = 103 feet.

c. An outfielder catches the ball three feet above the ground. How far has the ball traveled horizontally when the outfielder catches it?

To find the horizontal distance when h is 3, we set the equation equal to 3: –[tex]0.005x^2 + x + 3 = 3.[/tex] Simplifying gives x values where the ball is at 3 feet off the ground. After simplification, one possible solution would be the distance before the ball reaches its peak. However, solving this particular quadratic may require a calculator for precise roots, implying the distances at which the ball is 3 feet high.
