The hypothesis is the phrase following the word if = " 2 x+6=10"

The conclusion is the phrase following the word then = " x=2"

A specific, verifiable prediction of what the researcher(s) believe the study's results will be is known as a hypothesis (plural: hypothese). It is stated at the outset of the investigation.

Most often, this entails speculating on a potential correlation between two variables: the independent variable (what the researcher modifies) and the dependent variable (what the research measures).

The null hypothesis and the alternative hypothesis (known as the experimental hypothesis when the technique of examination is an experiment) are traditionally written as two separate forms of the hypothesis in research.

(a) The equation connecting y and x is y = 21 × 1 / x .

(b) The value of y when x = 21 is  1 .

(a) It is given that y is inversely proportional to x which means that it can be written as y ∝ 1 /x   an hence y = k × 1 /x    ......(1) where "k " is proportionality constant .

Putting y = 7 and x = 9 in equation (1) , we get

    7 = k × 1 / 3

    k = 7 ×  3

    k = 21

Hence , equation connecting y and x is y = 21 × 1 / x       ....(2)

   The equation that defines the parabola with vertex at the origin and directrix at x = -5/2 is

x = y²/10

We define what a parabola is

 The parabola is a geometric shape that is formed from the intersection of a vertical plane in a cone.

The canonical equation of a parabola is given by

(x - h)² = 4p(y - k)

The parabola is a quadratic function, it is composed of a vertex, or inflection point, a focus and a directrix.

Since the vertex and the focal axis are on the same axis, we analyze that:

v = (0, 0)

d = (-2.5, 0) them the focus is on the right so the parabola is of the form X = Y².

(y - 0)² = 4p(x - 0)

If the directrix is x = -5/2 then the focus will be:

f = (0 + p, 0)

0 + p = 2.5

p = 0 + 2.5

p= 2.5

(y - 0)² = 4*2.5(x - 0)

(Y)² = 10(X)

x = y²/10

The monthly payment for Jake borrowing $41,000 for 5 years at a 3% APR is $736.72.

Monthly payments are equal periodic payments made to offset an outstanding liability.

The monthly payments are the compounded principal (Principal + Compound Interest amount) divided by the number of periods.

The  monthly payments can be computed using an online finance calculator as follows:

N (# of periods) = 60 months (5 years x 12)

I/Y (Interest per year) = 3%

PV (Present Value) = $41,000

FV (Future Value) = $0

Results:

Monthly Payment (PMT) = $736.72

Sum of all periodic payments= $44,203.20

Total Interest = $3,203.20

Thus, Jake who borrowed $41,000 for 5 years at a 3% APR needs to make a monthly payment of $736.72 to settle the principal and the compounded interest.

Using the given information, the equation of the circle with center located at point (1 , -2) and passes through the point (0 , 1) is (x - 1)^2 + (y + 2)^2 = 10.

Using the distance formula, get the radius of the circle by solving for the distance between the center (1 , -2) and the point (0 , 1).

radius = distance = √(x2 - x1)^2 + (y2 - y1)^2

radius = √(0 - 1)^2 + (1 - -2)^2

radius= √1 + 9

radius = √10

The standard form of the equation of the circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.

Given the radius and center of the circle, substitute these values to the standard form of the equation of the circle.

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

where (h , k) = (1 , -2)

r = √10

(x - 1)^2 + (y - -2)^2 = (√10)^2

(x - 1)^2 + (y + 2)^2 = 10

A variable is a place where values are kept. The number of students in Shawn's school with at least one sibling is 367.

A variable is a quantity that could change depending on the circumstances of an experiment or mathematical problem. Typically, a variable is denoted by a single letter. The general symbols for variables most frequently used are the letters x, y, and z.

A variable is a symbol and a stand-in for any mathematical object in mathematics. A variable can specifically denote a number, a vector, a matrix, a function, its argument, a set, or one of its elements.

Let the number of students be x, then

25/32 = x/470

simplifying the above equation, we get

25(470) = 32x

32x = 11750

Dividing both sides of the equation by 32, we get

32x / 32 = 11750 / 32

x = 367

The value of x = 367.

Therefore, at least one sibling is present among 367 kids at his school.

The slope is -A/B and y-intercept is C/B in the line (A/D)x + (B/D)y = C/D

A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.

The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.  

Therefore,

m =  y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.

Be aware that tan ∅ = y/x.

We also refer to this tan as the line's slope

We know that the equation for slope(m) and y - intercept(c) of a line is given by :

y = mx + c

Here the equation is give as (A/D)x + (B/D)y = C/D, lets simply

⇒ (A/D)x + (B/D)y = C/D

⇒ B(y)/D = C/D -(A/D)x

⇒ [tex]\frac{B(y)}{D}[/tex] = [tex]\frac{C -A(x)}{D}[/tex]

⇒ B(y) = C - A(x)

⇒ y = [tex]\frac{C -A(x)}{B}[/tex]

Segments of the same length are said to be congruent. Collinear points are those that share a line. A mathematical assertion that can be validated is known as a theorem. A point that separates a segment into two congruent segments is the segment's midpoint.

Line sections are harmonious assuming that they have a similar length. You can utilize tick imprints to demonstrate harmonious line sections. In the triangle underneath, line fragments Stomach muscle and BC are harmonious.

Harmonious portions are sections that have a similar length. ≅ Focuses that lie on a similar line are called collinear. A hypothesis is a numerical explanation that can be demonstrated. The midpoint of a section is a point that separates the portion into two harmonious fragments.
