8. The equation of a straight line is 3x - 2y = 6 i. Find whether the point (0, 3) lies on it or not. ii .Find the equation of the straight line having the same slope and passing through the point (0, 3).​

Angles in a triangle add to 180 degrees

make a little equation for that

58 + 42 + x = 180

simplify

100 + x = 180

x = 180 - 100

x = 80

Hope this helps,

- Jeron :- )

Answer:

"18", "54", and "108"

Step-by-step explanation:

A straight line has an angle of 180 degrees. It can be seen as "half a circle", which has an angle of... 360 degrees, and since it's half, it's just 180 degrees.

Now we're also given the angles that compose the straight line (x, 3x, and 6x), and by adding these angles together, we should get the angle of the straight line. So that means that: [tex]x+3x+6x=180[/tex]

Now from here we can just combine them all into one term:

[tex]10x=180[/tex]

Now divide both sides by 10:

[tex]x=18[/tex]

Our angles are equal to "x", "3x", "6x", and to calculate their value, we just plug in "18" as x giving us: "18", "3(18)", "6(18)" which simplifies to the angles: "18", "54", "108"

The probability of not ordering nonalcoholic beverages is 66.

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favourable outcomes / Number of samples

Given that at a Noodles & Company restaurant, the probability that a customer will order a nonalcoholic beverage is 44%.

The probability of not ordering the beverages will be:-

P = 100% - 44%

P = 66%

Therefore, the probability of not ordering nonalcoholic beverages is 66.

The mean of even a dataset, often described as the mean and median, is the sum including all values divided by the overall number of values (as opposed to the geometric mean). This represents the most often used indicator of central tendency and is constantly referred to as the "mean." This is obtained by dividing the number of values contained within the dataset by the sum of all the values. Calculations can be conducted using either raw data or data that has been integrated into frequency tables. A number's average is called to as its average.

The class width for a frequency distribution with 9 classes is 35.

The difference between the highest and lowest values for a given data collection is the range in statistics. In statistics, we must put the given values, set of data, or set of observations in ascending order in order to determine the range. That indicates that you should start by writing the observations from lowest to highest value. The formula must now be used to determine the range of observations.

The range of the data is given as:

Range = highest value - lowest value

Range =  389 - 77

Range = 312

The class width for a frequency distribution with 9 classes is:

The amount of the down payment for the house, given the market value and the amount your bank requires is $ 36, 000

The bank that you work for requires that for mortgage loans, the applicants ( in this case Mr. and Mrs. Brady) , should be able to pay 1 / 5 of the market value of the property as down payment.

The down payment is therefore :

To find the percent change, we can use the formula:

percent change = (final value - initial value) / initial value * 100

In this case, the initial value is 8 and the final value is 120. Plugging in the values, we get:

percent change = (120 - 8) / 8 * 100 = 1,400%

So, the percent change in the number of Crayola crayon colors is 1,400%. This represents a significant increase from the initial 8 colors in 1903.

After 1 year of time period, Ana would have $1051.7 in her account, including interest.

Ana opened a bank account with $1000 that earns interest, compounded continuously, at an annual rate of r. To calculate the amount of money in the account after t years, we can use the formula:

[tex]A = P * e^{(rt)}[/tex]

where A is the amount in the account after t years, P is the initial deposit (in this case, $1000), r is the annual interest rate, and e is the mathematical constant approximately equal to 2.718.

For example, if the interest rate is 5% (r = 0.05), after 1 year, the amount in the account would be:

[tex]A = \$1000 * e^{(0.05 * 1)} = \$1000 * 1.0517[/tex]

[tex]A = \$1051.7[/tex]

So, after 1 year, Ana would have $1051.7 in her account, including interest. The higher the interest rate and the longer the time period, the more money Ana would have in her account due to the compounding effect.

A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure

The four types are parallelograms, squares, rectangles, and rhombuses

Properties of Parallelogram

Opposite sides are parallel

Opposite sides are congruent

Opposite angles are congruent.

Same-Side interior angles (consecutive angles) are supplementary

Each diagonal of a parallelogram separates it into two congruent triangles

The diagonals of a parallelogram bisect each other

Given data ,

Let the parallelogram be represented as EFGH

Now , the coordinates of the parallelogram is given by

Substituting the values in the equation , we get

The coordinate of E = E ( 1 , 3 )

The coordinate of F = F ( 3 , 5 )

The coordinate of G = G ( 4 , 2 )

The coordinate of H = H ( x , y )

Now , the difference in the x coordinates of F and G = ( 4 - 3 ) = 1

The difference in the y coordinates of F and G = ( 2 - 5 ) = -3

So , the coordinates of the point H = x coordinate of E + 1 and y coordinate of E - 3

The value for which the proportion of observations below it is equal to the proportion of observations above 115 is 85.

The normal distribution, also known as the Gaussian distribution or the bell curve, is a continuous probability distribution that describes the distribution of many real-world phenomena such as height, weight, IQ scores, and financial returns. It is a symmetric distribution with a bell-shaped curve that is centered on the mean and characterized by its mean and standard deviation.

Since the normal distribution is symmetric about the mean, the proportion of observations above 115 is equal to the proportion of observations below 100 - (115 - 100) = 85.

So, the value for which the proportion of observations below it is equal to the proportion of observations above 115 is 85.

The angle between the 3D vectors a = (3, -1, 2) and b = (1, -1, -2) is 2.23 radians. The angle between a = (0, -1, -3) and b = (2, 3, -1) is 2.43 radians.

The angle between two vectors a and b in three-dimensional space can be found using the dot product formula:

cos(θ) = (a * b) / (||a|| * ||b||)

Where ||a|| and ||b|| represent the magnitude (length) of vectors a and b, respectively, and "*" represents the dot product of the two vectors. The dot product is given by:

a * b = a1 * b1 + a2 * b2 + a3 * b3

Where a1, a2, and a3 are the components of vector a, and b1, b2, and b3 are the components of vector b. The angle θ is then calculated using the inverse cosine function:

θ = arccos(cos(θ))

Finally, the angle θ is expressed in radians.

For the first problem, we have:

a = (3, -1, 2)

b = (1, -1, -2)

So, we have:

a * b = 3 * 1 + (-1) * (-1) + 2 * (-2) = 3 - 1 - 4 = -2

||a|| = [tex]\sqrt{(3^2 + (-1)^2 + 2^2)} = \sqrt{(14)}[/tex]

||b|| = [tex]\sqrt{(1^2 + (-1)^2 + (-2)^2) }= \sqrt{(6)}[/tex]

cos(θ) = [tex](-2) / (\sqrt{(14)} * \sqrt{(6)} ) = -\sqrt{(2)} / \sqrt{(21)[/tex]

θ = arccos[tex](-\sqrt{(2)} / \sqrt{(21)})[/tex] = 2.23 radians (rounded to two decimal places)

For the second problem, we have:

a = (0, -1, -3)

b = (2, 3, -1)

So, we have:

a * b = 0 * 2 + (-1) * 3 + (-3) * (-1) = -3

||a|| = [tex]\sqrt{(0^2 + (-1)^2 + (-3)^2)} = \sqrt{(10)}[/tex]

||b|| = [tex]\sqrt{(2^2 + 3^2 + (-1)^2)} = \sqrt{(14)}[/tex]

cos(θ) = [tex]-3 / (\sqrt{(10)} * \sqrt{(14)}) = -3 / \sqrt{(140)}[/tex]

θ = arccos[tex](-3 / \sqrt{(140)})[/tex] = 2.43 radians (rounded to two decimal places)
