"h1: 1 > 2" represents a directional research hypothesis.

What is research hypothesis?

A research hypothesis is a specific, defensible, and testable assertion or prognosis regarding the anticipated outcomes of a scientific research study based on a particular characteristic of a population, such as alleged differences between groups on a single measure or correlations between variables.

The direction of the investigation is indicated by "h1: 1 > 2". This hypothesis predicts the direction of a relationship between the research variables by indicating that one variable will have a greater impact or value than the other variable. On the other hand, a non-directional study hypothesis would only state that there is a difference between the variables being looked at without indicating which direction the difference will travel.

Step-by-step explanation:

The formula to calculate the circumference of a circle is

\(2\pi \: r\)

By looking at the image we can see that the radios is 2 km, and we are going to use pi as 3.14. So..

Answer:

  yes, they are parallel; the general form equation differs only in the constant.

Step-by-step explanation:

Subtract y from the first equation and multiply by 2.

  y -y = 1/2x -y +3

  0 = x -2y +6

  x -2y +6 = 0 . . . . . put in general form

Compared to the second equation, we see the only difference is in the constant, +6 vs. -8.

This means the lines are parallel.

\(\sf{Given : 3tanx + 7 = \dfrac{2}{(1 - sinx)(1 + sinx)}}\)

We know that : (a - b)(a + b) = a² - b²

\(\implies \sf{3tanx + 7 = \dfrac{2}{1 - sin^2x}}\)

We know that : 1 - sin²x = cos²x

\(\implies \sf{3tanx + 7 = \dfrac{2}{cos^2x}}\)

\(\sf{\bigstar \ \ We \ know \ that : \boxed{\sf{\dfrac{1}{cos^2x} = sec^2x}}}\)

\(\implies \sf{3tanx + 7 = 2sec^2x}\)

We know that : sec²x = 1 + tan²x

\(\implies \sf{3tanx + 7 =2(1 + tan^2x)}\)

\(\implies \sf{2 + 2tan^2x - 3 tanx - 7 = 0}\)

\(\implies \sf{2tan^2x - 3 tanx - 5 = 0}\)

\(\implies \sf{2tan^2x - 5tanx + 2tanx - 5 = 0}\)

\(\implies \sf{2tanx(tanx + 1) - 5(tanx + 1) = 0}\)

\(\implies \sf{(tanx + 1)(2tanx - 5) = 0}\)

\(\implies \sf{tanx = -1 \ (or) \ tanx = \dfrac{5}{2} }\)

The units digit of the double factorial notation is the units digit of the product of all the even integers from 2 to 8, which is 8! The units digit of 8! is 8, so the answer is 8.

Factorials are mathematical operations symbolized by an exclamation point following a number. To find the factorial of a number, such as 5, write it down as 5! then multiply it by all the positive integers less than 5, including 1. Therefore, 5! is equivalent to 5 x 4 x 3 x 2 x 1, or 120. Factorials are frequently employed in mathematical equations and computations, especially in probability and statistics, where they are used to calculate the number of combinations or permutations that may be made from a given collection of numbers or variables. For example, if you had 5 distinct objects and want to determine how many various combinations , you used the factorial of 5.

The quadratic equation on the given graph can be written as:

y = (x + 2)*(x - 1)

Here we have the graph of a quadratic equation, we can see that the roots of the quadratic are:

x = -2 and x = 1.

Then if the leading coefficient is a, we can write the factorized form as:

y = a*(x + 2)*(x - 1)

We also know that the y-intercept is (0, -2), replacing these values we will get:

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

-2 = a*-2

-2/-2 = a

1 = a

9.  The stamp duty payable on a property with a purchase price of K45,000 is K1,350.

10. The stamp duty payable on a property with a purchase price of K150,000 is K7,500.

To calculate the stamp duty payable on properties with a purchase price of K45,000 and K150,000, we need to apply the corresponding rates of stamp duty based on the given information.

Given:

Value of Property:

Up to K35,000: Stamp Duty Rate - 2%

K35,000 to K70,000: Stamp Duty Rate - 3%

K70,000 to K140,000: Stamp Duty Rate - 4%

Over K140,000: Stamp Duty Rate - 5%

9. Calculate the stamp duty payable on properties whose purchase price is K45,000:

Since the purchase price of K45,000 falls within the range of K35,000 to K70,000, the stamp duty rate applicable is 3%.

Stamp Duty Payable = Purchase Price * Stamp Duty Rate

= K45,000 * 3%

= K45,000 * 0.03

= K1,350

Therefore, the stamp duty payable on a property with a purchase price of K45,000 is K1,350.

10. Calculate the stamp duty payable on properties whose purchase price is K150,000:

Since the purchase price of K150,000 is above K140,000, the stamp duty rate applicable is 5%.

Stamp Duty Payable = Purchase Price * Stamp Duty Rate

= K150,000 * 5%

= K150,000 * 0.05

= K7,500

Therefore, the stamp duty payable on a property with a purchase price of K150,000 is K7,500.

Answer:

Step-by-step explanation:

The area of the triangle with the given vertices is 11.5 square units.

The area of a triangle can be calculated using the coordinates of its vertices using the following formula.

To find the area of a triangle with vertices (x₁, y₁), (x₂, y₂), and (x₃, y₃), we can use the following formula:

A = (x₁(y₂ − y₃) + x₂(y₃ − y₁) + x₃(y₁ − y₂))/2

Using this formula with the given vertices (0, 6), (2, −3), and (3, 4), we get:

A = (0(-3 − 4) + 2(4 − 6) + 3(6 − (-3)))/2

A = (0 - 4 + 27)/2

A = 23/2

A = 11.5

Therefore, the area of the triangle with the given vertices is 11.5 square units.

Answer:

1. W=19, L=12

2. Next year Stephanie will be 14 and her Brother will be 6

3. 8, 9, 10

Step-by-step explanation:

1.

(a) W = 2L -5 => W - 2L = -5

(b) 2W + 2L = 62

Making (a)+(b):

3W = 57 => W = 19

from (a): L = (W+5)/2 = 12

2.

Today: S = 2B + 3 => S - 2B = 3 (a),

where S and B are Stephanie and Brother current age

2 years ago: (S-2) + (B-2) = 14,

so S + B = 14 + 4

S + B = 18 (b)

(a) - (b):

-3B = -15 => B = 5

from (a) S = 13

Verification:

2 years ago Stephanie was 11 and Brother was 3, the sum was 14, ok.

Next year Stephanie will be 14 and her Brother will be 6

3. We will find integers: s, m and b:

they are consecutive, so:

m = s+1

b = m+1 = s+2

and:::

s + 2m = b + 16 (a)

In (a) let's express all in terms of s:

s + 2(s+1) = s+2 + 16 =>

2s + 2 = 2 + 16 => s = 8, m=9, b=10

The correlation between Rate and Year is positive. The slope of the regression line is 0.0275 and the intercept is -9.8086. The model predicts that the interest rate in 2020 will be 2.38%.

The correlation between Rate and Year is positive, which means that as the years go by, the interest rate on 3-month Treasury bills is increasing. The slope of the regression line (0.0275) tells us that the average increase in the interest rate per year is 0.0275%. The intercept of the regression line (-9.8086) represents the interest rate in 1950.

This model predicts that the interest rate in 2020 will be 2.38%, which is obtained by plugging in 1970 for the Year variable and solving for the Rate. It's important to keep in mind that this model is based on historical data, and future interest rates may not follow the same pattern as in the past.
