The ounces of milk chocolate that the shop sells is 1/27 ounces.

A fraction is a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In a simple fraction, the numerator as well as the denominator are both integers.

In this case, the chocolate shop sold 1/6 ounces of white chocolate and it sold 2/9 times as much milk chocolate as white chocolate.

The milk chocolate sold will be:

= 1/6 × 2/9

= 2/54.

= 1/27

The ounces is 1/27 ounces.

The equation of the line in Slope-Intercept Form is y = 1/3x - 6

Given,

A line passes through the points (−6,−8) and (−3,−7).

To find the equation of the line in Slope-Intercept Form

Now, According to the question:

Write the slope formula :

[tex]m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

Substitute x1 = -6 , x2 = -3 and y1 = -8 , y2 = -7 into above slope formula:

Calculate;

[tex]m = \frac{-7-(-8)}{-3-(-6)}[/tex]

Determine the sign :

m = (-7+8)/ (-3+6)

m = 1/3

Substitute m = 1/3 , x = -6 and y = -8 into y = mx + b

Calculate:

-8 = 1/3 x (-6) + b

Reduce the expression:

-8 = -2 + b

-b = 6

b = -6

Again , Substitute

y = 1/3x - 6

m = 1/3  into y = mx +b:

y = 1/3x - 6

Hence, The equation of the line in Slope-Intercept Form is y = 1/3x - 6

Equation of the line 'm' is 5x - 6y - 30 = 0.

According to graph,

A(6,0) and B(0,-5) lies on the line m.

Slope-intercept form -> y = mx + c

Putting B(0,-5) in slope-intercept form,

-5 = m(0) + c

 c = -5

Putting A(6,0) in slope-intercept form,

  0 = m(6) - 5

6m = 5

 m = 5/6

Putting the values of m and c in slope-intercept form,

 y = (5/6)x - 5

6y = 5x - 30

5x - 6y - 30 = 0

The 90% confidence interval is  (5.09% , 5.41%)  and the 99% confidence interval is (52.24% , 52.76%)  .

In the question ,

it is given that ,

number of sample of loans taken = 28

the average of the sample is = 5.25%

the standard deviation of the normally distributed population is 0.5 %

The formula to find the Confidence Interval (CI) for the population mean is written as

[tex]\bar{x}[/tex] ±[tex]t_{n-1} , _{\alpha /2} \frac{\sigma}{\sqrt{n} }[/tex]

it is given that the 30 year fixed mortgage rates are normally distributed .

the sample size (n) = 28

Since sample size is less than 30 , the t - test is applied .

Sample mean ( [tex]\bar{x}[/tex] ) = 0.0525

the standard deviation (σ) = 0.005

the significance level : α = 1 - 0.90 = 0.1

critical value = [tex]t_{n-1} , _{\alpha}[/tex] = [tex]t_{27} , _{0.05}[/tex] = 1.703

So , 90% confidence interval will be :

= 0.525 ± (1.703)×(0.005/√28)

≈ 0.0525 ± 0.0016

= (0.0525 - 0.0016 , 0.0525 + 0.0016)

= (0.0509 , 0.0541)

= (5.09% , 5.41%)

For the 99% confidence interval ,

The constant rate of change of the altitude of the Hawk is -10 ft/s. The meaning of the -10 ft/s rate of change in altitude is the hawk is diving vertically down towards the prey with a speed of 10 feet per second

The average rate of change of a function is the rate at which the output values of the function changes with regards to the change in the argument of the function.

A function that has a constant rate of change is a linear function.

The rate of change of a linear function or equation that gives a straight-line graph is found from the slope, m, of the function.

The formula for the slope of a function, using the points (x₁, y₁), and (x₂, y₂), is presented as follows;

[tex]Slope, \, m = \dfrac{y_2-y_1}{x_2- x_1}[/tex]

a = first number of the series

d = common difference

n = number of series

Sum of first 50 counting numbers:

A department needs to choose six members consists of 3 women and 3 men from 10 men and 15 women. The number of ways it can be selected is 54,600.

If r persons need to be selected from total n members and the order does not matter, the number of ways it can be selected is calculated using the combination formula:

  ⁿCr = n! / [(n-r)! r!]

Data from the problem:

Total man = 10

Man to be chosen = 3

Total woman = 15

Woman to be chosen = 3

Hence,

The number of ways men can be selected =   ¹⁰C₃ = 10! /(3! 7!)

                                                                       = 120

The number of ways women can be selected =   ¹⁵C₃ = 15! /(3! 12!)

                                                                       = 455

The number of ways men and women selected:

= ¹⁰C₃ x  ¹⁵C₃

= 120 x 455 = 54,600 ways

Hence, the  number of ways the members can be selected =  54,600 ways.

What is the Pythagorean identity?

The Pythagorean trigonometric identity, also known as the Pythagorean identity, is a trigonometric identity that expresses the Pythagorean theorem. It is one of the fundamental relationships between the sine and cosine functions, along with the sum-of-angles formulae.

We have,

cosθ = 4/5

sin θ = ?

We'll use the definition of cos to find the known sides of the unit circle right triangle. The quadrant determines the sign on each of the values.

[tex]cos\theta = \frac{Adjacent}{hypotenuse} = \frac{4}{5}[/tex]

We know the hypotenuse and adjacent sides and we'll use the Pythagorean theorem to find the remaining side(opposite side).

opposite = √hypotenuse² − Adjacent²

opposite = √(5)² − (4)²

opposite = √25 - 16

opposite = √9

opposite = 3

[tex]sin\theta = \frac{opposite}{hypotenuse}[/tex]

sin θ = 3/5

In the fourth quadrant, the sine and tangent ratios are negative and the cosine ratio is positive.

Hence, the value of the sinθ is -3/5.

A parabola can be drawn given a focus of (−3,−3) and a directrix of x=5.

Now, let's take (x,y) to be the points of parabola.

So, we have the following expression:

Distance between (-3,-3) and (x,y) = Distance between (x,y) and x = 5

Distance between (x,y) and x = 5 will be Ix-5I

Now, we will use distance formula to solve this expression further.

[tex]\sqrt{(y+3)^{2}+ (x+3)^{2} }= (x-5)} }[/tex]

Squaring on both sides of the equation:

[tex]{(y+3)^{2}+ (x+3)^{2} }= (x-5)^2} }[/tex]

[tex]y^{2}[/tex]+9+6y+[tex]x^{2}[/tex]+9+6x = [tex]x^{2}[/tex]+25-10x

[tex]y^{2}[/tex]+6y+6x+18-25+10x = 0

The distance between the complex plane's origin (0, 0) and the point (a, b) is what is known as the absolute value of a complex number, a+bi (also known as the modulus).

Without taking into account direction, absolute value defines how far a number is from zero on the number line. A number's absolute value can never be negative. Look at some illustrations. 5 is the sum of its absolute values. There are 5 units between 5 and 0. A number's absolute value is determined by how far it is from zero on the number line. For instance, the absolute value of -7 would be 7, as it is 7 units away from zero. Additionally, since 0 is 7 units distant, the value of 7 would likewise be 7.
