Answer:

SSS is the congruence theorem that can be used to prove Δ LON is congruent to Δ LMN ⇒ 1st answer

Step-by-step explanation:

Let us revise the cases of congruence

SSS ⇒ 3 sides in the 1st Δ ≅ 3 sides in the 2nd Δ
SAS ⇒ 2 sides and including angle in the 1st Δ ≅ 2 sides and including angle in the 2nd Δ
ASA ⇒ 2 angles and the side whose joining them in the 1st Δ ≅ 2 angles and the side whose joining them in the 2nd Δ
AAS ⇒ 2 angles and one side in the 1st Δ ≅ 2 angles and one side in the 2nd Δ
HL ⇒ hypotenuse leg of the 1st right Δ ≅ hypotenuse leg of the 2nd right Δ

In triangles LON and LMN

∵ LO ≅ LM ⇒ given

∵ NO ≅ NM ⇒ given

∵ LN is a common side in the two triangles

- That means the 3 sides of Δ LON are congruent to the 3 sides

of Δ LMN

∴ Δ LON ≅ LMN ⇒ by using SSS theorem of congruence

SSS is the congruence theorem that can be used to prove Δ LON is congruent to Δ LMN

PLEASE SOLVE THE QUESTIONS (WILL MARK BRANLIEST)

Answer:

a) 4⁻³ = 1/64 = 0.015625

b)13⁻² = 1/169 = 0.0059171598

c)(-3)⁻² = 1/-3² = 0.1111111111

Step-by-step explanation:

To solve the question above, when we have an integer ( positive or negative) that is raised to a negative power, this means the reciprocal of that integer raised to the positive power

Example:

a⁻ⁿ = 1/aⁿ

a) 4⁻³ = 1/4³

= 1/(4 × 4 × 4)

= 1/64

= 0.015625

b) 13⁻² = 1/13²

= 1/(13 × 13)

= 1/169

= 0.0059171598

c)(-3)⁻² = 1/-3²

= 1/(-3 × -3)

= 1/9

= 0.1111111111

Which is the correct null hypothesis for testing if the independent variable is a significant predictor of the dependent variabl

azamat

Answer:

Option A) $H_0: \beta_1 = 0$

Step-by-step explanation:

The regression equation gives us a relation between the independent and the dependent variable.

The regression equation with 1 independent variable can be written as:

$y = \beta_0 + \beta_1x\\\text{where } \beta_0 \text{ is the y intercept and } \beta_0 \text{ is the coefficient of x or the independent variable.}$

The hypothesis tells us whether the dependent variable have a significant relationship with the independent variable or not.

We test that there is no effect of the particular dependent variable on the predicted variable.

We carry this hypothesis with the null hypothesis that there is no significant relationship between the dependent variable and the independent variable

Thus, we check whether the coefficient of x is zero or not.

The null hypothesis can be designed as:

$H_0: \beta_1 = 0$

The p-value for each term tests the null hypothesis that the coefficient is equal to zero (no effect).

Option A) $H_0: \beta_1 = 0$
