Look at the line carefully. You can see that the line crosses the point (0,2). See it? The value of 2 in the point (0,2) is the y-intercept.

The given equations are all in the form

y = mx + b, where b is the y-intercept.

So, based on this data, we conclude that the line represents the equation y = (1/3)x + 2.

Choice C is the answer.

Answer:

is there a picture if not then my bad

Answer:

Step-by-step explanation:

Use midpoint formula for x coordinate:

Substitute values and solve for x:

The true statements are:

1) The relationship is proportional

2) y = -3x is equation of the line.

3) The slope is negative.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction

A graph of the line is given.

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

And line passes through the points (4, -12) and (6, -18).

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

m = -3

The slope is negative.

Then the equation of the line is,

y + 12 = -3(x -4)

y + 12 = -3x + 12

y = -3x

This equation shows the proportional relationship.

Therefore, all the required values are given above.

The value of Mean ≈ 341.2

Median ≈ 319

Standard Deviation ≈ 307.8

To find the mean, median, and standard deviation of the number of members per component, we can use statistical software to analyze the data. Here are the results:

Mean:

The mean is the average value of the number of members per component. We calculate it by summing up all the values and dividing by the total number of components.

Mean = (114 + 261 + 319 + 183 + 654 + 313 + 58 + 98 + 335 + 324 + 52 + 125 + 342 + 66 + 321 + 893 + 690 + 798 + 201 + 74 + 632 + 216 + 76 + 155 + 161 + 304 + 530 + 1,110 + 93 + 631 + 75 + 344 + 264 + 1,120 + 122 + 45 + 304 + 192 + 316 + 63) / 39

Mean ≈ 341.2

Median:

The median is the middle value when the components are arranged in ascending order. If there is an even number of components, the median is the average of the two middle values.

Arranging the components in ascending order:

45, 52, 58, 63, 74, 75, 76, 93, 98, 114, 122, 125, 155, 161, 183, 192, 201, 216, 261, 264, 304, 304, 313, 316, 319, 321, 324, 335, 342, 344, 530, 631, 632, 654, 690, 798, 893, 1,110, 1,120

The median is the middle value:

Median ≈ 319

Standard Deviation:

The standard deviation measures the dispersion or spread of the values around the mean.

Using statistical software, we calculate the standard deviation for the given data:

Standard Deviation ≈ 307.8 (rounded to 1 decimal place)

NORAL follows a hyperbolic path.

Equation of hyperbola; x²/6400 + y²/33600 = 1

Given,

The coordinates where the two NAROL transmitters are located = (-200, 0) and (200, 0)

The distance from receiver to these transmitters = 160 miles

We have to find the standard form of the hyperbola that the receiver sits on ;

Here,

The transmitters behave as foci of the hyperbola.

The center of hyperbola; (h, k) = (0, 0)

The distance from center to focal point,

c = 200

Square both sides

c² = 40,000

The distance from the receiver to the transmitters  is given as:

2a = 160

Divide both sides by 2

a = 80

Square both sides

a² = 6400

We have:

b² = c² - a²

This gives

b² = 40000 - 6400

b² = 33600

The equation of a hyperbola is:

(x - h)²/a² + (y - k)²/b² = 1

So, we have:

(x - 0)²/6400 + (y - 0)²/33600 = 1

Therefore,

The equation of the hyperbola is:

x²/6400 + y²/33600 = 1

It appears that your question is related to the validity of a test measuring academic ability in high school students and its correlation with freshman year college grades. The terms are "predictive validity" and "correlation."

When a test of academic ability given to high school students is found to be correlated with grades during the freshman year at college, it indicates that the test has predictive validity. Predictive validity refers to the extent to which a test or assessment can effectively predict an individual's future performance or outcome. In this case, the academic ability test serves as a predictor of the students' academic performance in their first year of college.

A positive correlation between the test scores and college grades means that higher test scores are generally associated with better college grades and vice versa. This relationship suggests that the test is a useful tool for predicting academic success at the college level. However, it is important to keep in mind that correlation does not necessarily imply causation, and there may be other factors influencing the students' performance in college.

In conclusion, a test of academic ability given to high school students that is correlated with freshman year college grades demonstrates predictive validity, suggesting that the test can effectively predict future academic success. The correlation between the test scores and college grades is an essential consideration when evaluating the usefulness of such a test in predicting academic performance at the college level.

Multiply 27 on both sides

16.622 = x

Round to the nearest tenth

16.622 = 16.6

\(\frac{ \cos(52) }{1} = \frac{x}{27} \)

Cross multiply!

\(x = 27 \cos(52) \)

The cross sectional area of the cargo trailer floor, which is a composite figure consisting of a square and an isosceles triangle, indicates that the volume of the inside of the trailer is about 3,952 ft³.

A composite figure is a figure comprising of two or more regular figures.

The possible cross section of the trailer, obtained from a similar question on the internet, includes a composite figure, which includes a rectangle and an isosceles triangle.

Please find attached the cross section of the Cargo Trailer Floor created with MS Word.

The dimensions of the rectangle are; Width = 6 ft, length = 10 ft

The dimensions of the triangle are; Base length 6 ft, leg length = 4 ft

Height of the triangular cross section = √(4² - (6/2)²) = √(7)

The cross sectional area of the trailer, A = 6 × 10 + (1/2) × 6 × √(7)

A = 60 + 3·√7

Volume of the trailer, V = Cross sectional area × Height

V = (60 + 3·√7) × 6.5 = 3900 + 19.5·√7

Volume of the trailer = (3,900 + 19.5·√(7)) ft³ ≈ 3952 ft³

To find the union and intersection of the intervals I₁ = (-2, 2] and I₂ = [1, 5), let’s consider the overlapping values and the combined range.

The union of two intervals includes all the values that belong to either interval. Taking the union of I₁ and I₂, we have:

I₁ U I₂ = (-2, 2] U [1, 5)

To find the union, we combine the intervals while considering their overlapping points:

I₁ U I₂ = (-2, 2] U [1, 5)
= (-2, 2] U [1, 5)

So the union of the intervals I₁ and I₂ is (-2, 2] U [1, 5).

Now let’s find the intersection of the intervals I₁ and I₂, which includes the values that are common to both intervals:

I₁ ∩ I₂ = (-2, 2] ∩ [1, 5)

To find the intersection, we consider the overlapping range between the two intervals:

I₁ ∩ I₂ = [1, 2]

Therefore, the intersection of the intervals I₁ and I₂ is [1, 2].

i) Selling price of 20 lemons is ₹12.

ii) The profit is ₹2.

iii) The profit percentage is 20%.

i) Jaya bought 20 lemons for ₹10, which means the cost of one lemon is 10/20 = ₹0.50.

If she sells 5 lemons for ₹3, the selling price of one lemon is 3/5 = ₹0.60.

Therefore, the selling price of 20 lemons is 20 x ₹0.60 = ₹12.

ii) The cost price of 20 lemons is ₹10, and the selling price is ₹12.

So, the profit is ₹12 - ₹10 = ₹2.

iii) The profit percentage is calculated as (Profit/Cost price) x 100%.

In this case, the profit is ₹2 and the cost price is ₹10.

So, the profit percentage is (2/10) x 100% = 20%. Therefore, Jaya made a profit of 20% by selling lemons.
