it is stated in a question form it poses an expected relationship between variables it reflects a theory it is testable
The correlational hypothesis is a type of research hypothesis that proposes a relation between two variables.
Hypothesis proposes that there is a relationship or association between two variables, known as the independent and dependent variables.
The relation between the two variables can be positive or negative. A positive relation means that as the independent variable increases, the dependent variable also increases.
On the other hand, a negative relation means that as the independent variable increases, the dependent variable decreases.
The strength of the relation can be determined by calculating the correlation coefficient, which is a numerical representation of the strength of the relation between two variables.
In the mathematical representation of a correlational hypothesis, the equation
=> Y = mX + b
is used, where m represents the slope of the line and b represents the intercept. The slope of the line reflects the strength of the relation between the independent and dependent variables, while the intercept reflects the starting point of the relation.

If h(x) =x+2 , g(x) =x² and f(x) =-x , find the values of x for which gh(x) =f(x)
The values of x for which gh(x) = f(x) are -1 and -4.
As a result, we have gh(x) = g(h(x)) = g(x + 2). ² = x² + 4x + 4 f(x) = -x
The equation must be solved in order to determine the range of x values for which gh(x) = f(x):
x² + 4x + 4 = -x
When all the phrases are moved to the left, we obtain:
x² + 5x + 4 = 0
This quadratic equation has the following factors:
(x + 1)(x + 4) = 0
Thus, either x + 1 = 0 or x + 4 = 0 is the answer.

Convert the number to scientific notation.
120,000,000,000,000
Answer:
1.2 x [tex]10^{14}[/tex]
Step-by-step explanation:
Scientific notation OR standard form:
This is expressed in powers of 10 (i.e [tex]10^{x}[/tex])
If the decimal point cannot be visibly seen, you can deduce that the decimal point is currently located after the last digit (i.e ‘0’).
For the number to be expressed in scientific notation, the decimal point has to be placed right after the first digit (which is NOT a zero) in the left most direction.
For this number, the decimal point has to be placed right after the ‘1’. Therefore, the decimal point will be moving 14 places to the left. In addition, this 14 is considered as the positive power of 10.
Answer:
1.2 × 10¹⁴
Step-by-step explanation:
Scientific notation is written in the form [tex]a \times 10^n[/tex], where [tex]1 \leq a < 10[/tex] and [tex]n[/tex] is any positive or negative whole number.
To convert a number into scientific notation, move the decimal point to the left or right until there is one non-zero digit to the left of the decimal point.
The number of times you have moved the decimal point is the power of 10 (the value of n).
If the decimal point has moved to the left, n is positive.If the decimal point has moved to the right, n is negative.Therefore, to convert 120,000,000,000,000 to scientific notation, move the decimal point 14 places to the left so that [tex]a[/tex] is 1.2.
As the decimal point has been moved 14 places the left, we need to multiply 1.2 by 10¹⁴.
Therefore, 120,000,000,000,000 = 1.2 × 10¹⁴.

Suppose you purchased a shirt for $16.51 using a coupon. If the shirt originally costs $25.40, what was the percent discount from the coupon? Simplify your answer completely.
The discount can be found by subtracting the sale price from the original price:
$25.40 - $16.51 = $8.89
So the discount was $8.89.
To find the percent discount, we can divide the discount by the original price and multiply by 100:
$8.89 / $25.40 * 100% = 35%
Therefore, the percent discount from the coupon was 35%.
A $9070 investment earns interest at
3.3% per year compounded
semiannually over 17 years. Use the
compound interest formula to
calculate the value of this investment
to the nearest cent.
Answer:
The investment will be worth $16898.67 after 17 years, compounded semiannually at 3.3% per year.
Step-by-step explanation:
The compound interest formula is:
A = P * (1 + (r/n))^(nt)
where
A is the amount of the investment after t years,
P is the principal amount (9070),
r is the annual interest rate (3.3%),
n is the number of times the interest is compounded per year (2),
t is the number of years (17).
Using the formula:
A = 9070 * (1 + (0.033/2))^(2 * 17)
A = 9070 * (1.0165)^34
A = 9070 * 1.882611
A = 16898.67 to the nearest cent.
So the investment will be worth $16898.67 after 17 years, compounded semiannually at 3.3% per year.

A*B'C D'E using a series of two different transformations. They give two different
answers.
Answer the questions to investigate ways to transform ABCDE.
Olivia finds a combination of two different transformations that moves ABCDE
onto A'B'C'D'E'. What is one way she might have done this?
Answer: One way that Olivia might have found a combination of two transformations to move figure ABCDE onto figure A'B'C'D'E' is by using a combination of translations and rotations.
A translation is a type of transformation that moves a figure a certain distance in a specified direction, without changing its size or orientation. A rotation is a type of transformation that turns a figure about a fixed point, called the center of rotation, by a certain angle.
Olivia might have first translated figure ABCDE to a new location and then rotated it about a point to match the orientation of A'B'C'D'E'. For example, she could have translated figure ABCDE so that one vertex coincides with a corresponding vertex in A'B'C'D'E', and then rotated it about that common vertex so that the sides match up.
Alternatively, Olivia might have first rotated figure ABCDE to a new orientation and then translated it to the final position. The sequence of transformations could have been different, but the end result would still be figure ABCDE matching the orientation and position of A'B'C'D'E'.

An obtuse angle has a measure of 150°. The angle was bisected. Each of those angles was then trisected. Finally, each of those angles was divided into 5 equal parts. How large is the smallest angle?
The smallest angle is 5° when each of those angles was divided into 5 equal parts.
What is an Angle ?In Geometry, an angle is a figure which is produced by two rays, which share a common point called a vertex. The two rays stand in for the angle's two sides. The Roman word "Angulus," which means "corner," is where the term "angle" originates. The intersection of two curves in this plane results in the angles. Angles of several kinds can be generated on a planar surface. As follows:
Acute Angle
Obtuse Angle
Right Angle
Reflex Angle
Straight Angle
Full Angle
Obtuse Angle :An angle greater than 90° but less than 180° is referred to as a "obtuse angle." An obtuse angle is between a right angle and a straight angle.
Now in this question,
Starting with an obtuse angle of 150°, bisecting it gives two angles of 75° each.
Trisecting each of these angles gives three angles of 25° each.
Dividing each of these angles into 5 equal parts gives angles of 5° each.
Therefore, the smallest angle is 5°.

The line represents a direct variation function.
The line has a slope of - 3/4.
The point (9, -12) is also on the line.
The line has a slope of 3/4 .
Answer:
The line has a slope of - 3/4.
The line has a slope of 3/4.
Step-by-step explanation:
To determine the slope of a line passing through two points, you can use the formula:
Slope = (y2 - y1) / (x2 - x1)
Using the points (-6, 8) and (-3, 4), the slope would be:
Slope = (4 - 8) / (-3 - (-6)) = -4 / 3 = -4/3
So, the line has a slope of -4/3. The other statements in the list are not necessarily true based on the given information.
