The table that accurately identifies the three points of the graph is table 1.

A proportional relationships are relationships between two variables where their ratios are equivalent.

The variables are time in hours and earnings.

Therefore,

y = kx

where

A student earns $8.50 per hour working in a library.

Hence,

y = 8.50x

when x = 2

y = 8.50(2) = 17 dollar

when x = 4

y = 8.50(4) = 34 dollar

when x = 8

y = 8.50(8) =  68 dollar

Therefore, the table that reflects the graph is table 1.

Answer:

- X - 2x = 2x

- X 5y = -5y

(5x - 8y) (2x - 5y)

5x X 2x = 10x^2

5x X -5y = -25xy

-8y X 2x = -16xy

-8y X -5y = 40y^2

therefore

= 10x^2 + 40y^2 -25xy -16xy

Jim needs a score of 115 on his third test to keep an average of 89 or greater.

A mean represents the average value among a set of values.

Mean = (sum of all values)/(total number of values)

In other words, mean is the value assigned to each member of set after fair distribution. It means that if a set of n values has a mean of x, we can assume the set to be 'x' value recurring n times over the sample.

In this case, we have 3 test results: 83, 69 & x, where x is the unknown result of 3rd test. Our required minimum average/mean is 89.

Substituting these in our formula for mean, we get:

[tex]89=\frac{83+69+x}{3} \\89*3=152+x\\x=267-152=115[/tex]

Thus, 115 is our required test result for maintaining average of minimum 89.

The t-score of 2.779 is used to find the 99% confidence interval for the population mean.

Given,

Assume that orangutans' heights, measured in inches, are regularly distributed with an unidentified mean and standard deviation. The population means are calculated using the orangutan heights of 27 orangutans that were randomly selected.

What t-score should be applied to determine the population mean's 99% confidence interval?

n = 27

confidence level = 0.99

We have to find a critical value for the confidence level of 0.99.

To find the critical value we need degrees of freedom and significance level.

df = n-1 = 27 - 1 = 26

α = 1 - 0.99 = 0.01

α/2 = 0.01/2 = 0.005

For α/2 = 0.005 and df = 26, the critical value using the above table is,

t-critical value = 2.779

The capital gains his earned is $2,625

What is capital gains?
Capital gain is the profit obtained from the sale of assets whose value is higher or increased than when the asset was purchased.

The first is to calculate the difference price when selling and purchasing.

= ((100% + 20%) × $52.50) - $52.50

With the substitution formula, we can simplify it to:

= 20% × $52.50
= $10.5

Next is to multiply the difference price to share he purchased.

= $10.5 × 250
= $2,625

Thus, the capital gains his earned is $2,625

The yield on a corporate bond with a face value of $1000 after removal of discount would be =$60.

Interest rate can be defined as the payment received by an individual after investing a particular amount of money for a given period of time.

The principal amount after removal of $950 discount = $1000

The rate of interest (R) = 6%

The time of investment (T) = 1

Then the simple interest;

= P × T × R/100

= 1000 × 1 × 6/100

= 6000/100 = $60

Therefore, the yield of the corporate bond would be extra $60.

The radius of the roundabout whose circumference is given is: 55 feet.

What is circumference?

The perimeter of a circle or ellipse is known as its circumference in geometry (from the Latin circumferens, meaning "carrying around"). That is, if the circle were opened up and straightened out to a line segment, the circumference would be the length of the arc.

As given in the question ,  

The circumference of the roundabout is 345.4 feet.

and we need to find the radius,

We know that, the circumference is calculated by:

Circumference = 2 π r

Because a 270° rotation around the origin and a subsequent reflection over the x-axis translate ABC onto LMN, the figures are congruent.

Two figures are said to be "congruent" if they can be positioned perfectly over one another. Both of the bread slices are the same size and shape when stacked one on top of the other. Congruent refers to things that are exactly the same size and form. Congruent refers to something that is "absolutely equal" in terms of size and form. The shapes hold true regardless of how we rotate, flip, or turn them. Draw two circles with the same radius, for instance, cut them out, then stack them on top of one another. In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other.

Now it is given that each guest needs 70cm along the circumference of the table, and we need to find out the number of guests that can be seated at the table. This can be done by dividing the circumference with the length occupied by each guest along the table as ,

AS per the concept of trigonometric ratios for theta, the value of cos θ = 2√6/5 , tan θ = -1/2√6 , cosec θ = -5, sec θ = 5/2√6 and the value of cot θ = -2√6.

Trigonometric ratio:

In math, there are six trigonometric ratios they are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

Given,

The angle theta is in standard position with a terminal arm in quadrant IV. If sin θ =-1/5.

Now, we have to find the remaining five trigonometric ratio of the θ.

As we know that,

sin²θ + cos²θ =  1

Here we know that value of sin θ = -1/5, then the value of cos θ is calculated as,

=> (-1/5)² + cos² θ = 1

=> 1/25 + cos² θ = 1

=> cos² θ = 1 - 1/25

=> cosθ = √24/25

=> cos θ = 2√6/5

So, the value of tan θ = -1/2√6

Then the value of cosec θ = -5, sec θ = 5/2√6 and the value of cot θ = -2√6.

Given,

A fish tank in a pet store has 21 fish in it. 9 are orange and 12 are white. determine the probability that if we select 4 fish from the tank, at least 2 will be white;

The probability that the fish is white = 12/21

                                                      = 4/7

To find the probability that at least two will be white,

P(x ≥ 2) = 1 - P(x < 2) = 1 - ( P(0) + P(1) )

The binomial distribution formula [tex]P(x) = (^n_x)p^xq^n^-^x[/tex] where p is the probability of success and q is the probability of failure.

From the above formula;

P(x ≥ 2) = 1 + [ (3/7)⁴ + 4*(4/7)*(3/7)³ ]

            = 0.7863

For the function F(x, y) = x³ + y³ - 3x² - 6y² - 9x ,  the local maximum value is 5 and the local minimum value is -3. The graph is discontinuous, so we cannot locate the saddle points.

In mathematics, a saddle point or minimax point is a point on the surface of the graph of a function where the slopes (derivatives) in orthogonal directions are all zero (a critical point), but which is not a local extremum of the function.

We have the following function -

F(x, y) = x³ + y³ - 3x² - 6y² - 9x

We will plot the 3 dimensional graph of this function. From the model it can be seen that, the local maximum value is 5 and the local minimum value is -3. Since the graph is discontinuous, we cannot locate the saddle points.

Therefore, for the function F(x, y) = x³ + y³ - 3x² - 6y² - 9x ,  the local maximum value is 5 and the local minimum value is -3. The graph is discontinuous, so we cannot locate the saddle points.

Parallel lines in geometry are coplanar, straight lines that don't cross at any point. In the same three-dimensional space, parallel planes are any planes that never cross. Curves with a predetermined minimum distance between them and no contact or intersection are said to be parallel.

Here, we have

Given equations = 5(x+3) and y=5x+1

Now we write both equations in standard form and we get

y = 5x + 3,
