The standard form of the line with x-intercept of 6 and y-intercept of 5 is

5x + 6y = 30

The equation in standard form can be represented as follows:

Ax + By = C

Where

Therefore, let's find the standard form of the equation with x -intercept of 6 and y-intercept of 5.

The x-intercept is the value of x when y = 0 and the y-intercept is the value of y when x = 0.

Therefore,

(6, 0)(0, 5)

using the form y = mx + b

where

m = 5 - 0 / 0 - 6

m = - 5  / 6

Therefore,

y = - 5 / 6 x + 5

5  /6 x + y = 5

multiply through by 6

Therefore,

5x + 6y = 30

Applying the definition of perpendicular bisector, the value of x is: 10.

A perpendicular bisector can be defined as any line segment that bisects another line segment. That is, it divides another line segment into two equal parts having the same length.

Since AD is the perpendicular bisector of BD, then, BD = DC.

BD = 5x - 10

DC = 3x + 10

Substitute

5x - 10 = 3x + 10

Combine like terms

5x - 10 + 10 = 3x + 10 + 10 [addition property of equality]

5x = 3x + 20

5x - 3x = 3x + 20 - 3x [subtraction property of equality]

2x = 20

Divide both sides by 2

2x/2 = 20/2 [division property of equality]

x = 10

The value of x is 10.

Mark had to pay 70 percent of the original price.

What is percent?

A % in mathematics is a quantity or ratio that is stated as a fraction of 100 (from the Latin per centum, "by a hundred"). Even though the acronyms "pct.", "pct.", and even "pc" are also employed the percent symbol, "%," is frequently used to indicate it. A percent lacks dimensions and has no associated unit of measurement. The ratio's numerical value is multiplied by 100 to obtain the percent value. The Latin word per centum, which means "hundred" or "by the hundred," is where the word "percent" originates. The Italian word per cento, which means "for a hundred," gradually shrank to become the symbol for "percent."

Mark paid = $385

Original price = $550

Percent what Mark pay = (385/550) x 100 percent

                                       = 70 percent

Hence, Mark had to pay 70 percent of the original price.

The probability that a bowling ball chosen at random would be discarded because it is too heavy to use is 0.3204.

The population's mean weight (μ) is equal to 14.6 pounds.

The standard deviation (σ) is equal to 3 pounds.

Assuming a normal distribution, the corresponding z-score for each given weight "X" is calculated as follows:

z = (x - µ)/σ

For X = 16 pounds:

z = (16 - 14.6)/3

z = 0.4667

A z-score of 0.4667 is equivalent to the 67.96-th percentile of the distribution. The probability of a ball being discarded is:

P(z > 0.4667) = 1 - 0.6796 = 0.3204

The probability that a randomly selected bowling ball is discarded due to being too heavy to use is 0.3204 or 32.04%.

Answer:

x = 12 and y = (3/2)

Step-by-step explanation:

"Y varies directly as x," can be written as:

y = mx

The connecting law is m, which relates how much y will change for a change in x.  m is given by:

m = y/x

To find m, the slope, use the two given values for x and y:

m = y/x

m = 3/4

This yields:

y = (3/4)x

Now we can find:

X when y=9:    

y = (3/4)x

9 = (3/4)x

x = (4/3)*9

x = 12

Y when x=2:  

y = (3/4)x

y = (3/4)*2

y = (3/2)

What is compound interest?

Compound interest is when interest on a loan, investment, or savings account grows exponentially over time rather than linearly.

Formula to calculate simple interest

I = Prt

Where, I = Simple interest

t = time

r = earned interest

P = Compound interest

Here, we have

P = $4000, r = 2.5%, t = 9 years

By applying the compound interest formula, we get

I = 4000×0.025×9

= 900

The total amount after 9 years is 4000+900= 4900

Hence,

a. Noah will have money in the account after 9 yrs is $4900.

The equation of the parabola is y = -5x^2 + 3

The points and the vertex represent the given parameters

From the question, we can see that the equation is a parabola

A parabola function is represented as

y = a(x - h)^2 + k

Where

Vertex = (h, k)

Point = (x, y)

From the question, we have

Vertex = (h, k) = (0, 3)

Point = (x, y) = (1, -2)

So, we have

y = a(x - 0)^2 + 3

Evaluate

y = ax^2 + 3

Using the point, we have

-2 = a(1)^2 + 3

This gives

a = -5

So, we have

y = ax^2 + 3

y = -5x^2 + 3

Hence, the equation is y = -5x^2 + 3

There were three orange sweets in the given packet.

What is ratio and how can it be assessed?
A ratio is the comparative or condensed form of two quantities of the same type. We may determine how many times one quantity is equal to another using this relationship. The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects. A ratio is indicated by the symbol ":".

Given, the ratio of purple to orange sweets = 4 : 1
Total number of sweets including both purple and orange = 15 -(i)
Let x be the ratio constant for the given ratio.
Therefore, number of purple sweets = 4x -(ii)
Also, the number of orange sweets = 1x = x -(iii)
From (i), (ii) and (iii), we get, 4x + x = 15 ⇒ 5x = 15 ⇒ x = 3
Putting the value of x in (ii), we get number of purple sweets = 4x = 12
Putting the value of x in (iii), we get number of orange sweets = x = 3
Thus, there were three orange sweets in the given packet.
