**Answer:**

x = 15

**Step-by-step explanation:**

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

3x - 5 is an exterior angle of the triangle, then

3x - 5 = x + 25 ( subtract x from both sides )

2x - 5 = 25 ( add 5 to both sides )

2x = 30 ( divide both sides by 2 )

x = 15

**Answer:**

40° and 115°

**Step-by-step explanation:**

x+3x-5+25°=180°(angle on a straight line)

**Step-by-step explanation:**

k (x)=6x-12 ; k(x)=15

The **input value **x in the **function **k( x ) = 6x - 12 when k( x ) = 15 is 9/2.

A **function **is simply a relationship that maps one input to one output, that is, each x-value can only have one y-value.

Given the data in the question;

k( x ) = 6x - 12k( x ) = 15x = ?To determine the value of x, equate the function to 15 and solve for x.

k( x ) = 6x - 12

k( x ) = 15

15 = 6x - 12

Rearrange the equation

6x - 12 = 15

Collect like terms

6x = 15 + 12

6x = 27

Divide but sides by 6

6x/6 = 27/6

x = 27/6

x = 9/2

Therefore, the **input value **(**x**) is 9/2, this forms an ordered pair of ( 9/2, 15 ).

Rebecca wants to prove that if the diagonals in a parallelogram are perpendicular, then it is a rhombus.

It is shown that if a parallelogram's diagonals are **perpendicular**, the parallelogram is a **rhombus.**

A parallelogram is a **quadrilateral **with two **parallel** sides (and therefore opposite angles equal).

A rhombus is a quadrilateral with all of its sides equal. Because opposite **sides** of a parallelogram are **equal**, a rhombus is a type of parallelogram in which all sides are equal.

We must demonstrate that if the diagonals of a parallelogram are perpendicular, then the parallelogram is a rhombus.

Let ABCD be a parallelogram .

Consider Δ AOD and Δ COD

Since, a parallelogram's diagonals bisect each other we can say that,

AO = CO

∠AOD = ∠COD = 90°

DO = OD

Δ AOD ≅ Δ COD [SAS rule]

∴ AD = CD

Because the parallelogram's adjacent sides are equal, we can conclude that all four sides are equal.

A restaurant chain is measuring the levels of arsenic in chicken from its suppliers. The question is whether there is evidence that the mean level of arsenic is greater than 80 ppb, so we are testing vs , where represents the average level of arsenic in all chicken from a certain supplier. It takes money and time to test for arsenic so samples are often small. A sample of chickens from one supplier is tested, and the resulting sample mean is . Subtracting 11 from the sample data to move the mean down to the null mean of results in the following data: . 62, 78, 89, 95, 95, 137

The **p**-**value** of the test is 0.1515 which concludes that the **average** **amount** of **arsenic** in chicken from **suppliers** is 80 ppb.

The **test** **hypothesis** is as follows:

H₀: The mean amount of arsenic is 80 ppb, i.e. μ= 80.

Hₐ: The mean amount of arsenic is more **significant** than 80 ppb, i.e.μ > 80.

We will apply a **t**-**test** for a single mean because the population standard deviation is **unknown**,

It is assumed that the **sample** **means** [tex]\bar{x}[/tex] = 91.

The adjusted sample presented is:

S = { 62, 78, 89, 95, 95, 137}

Calculate the sample **standard** **deviation** as follows:

[tex]\bar{x}[/tex] = 62 + 78 + 89 + 95 + 95 + 137 =80

[tex]s =\sqrt{\frac{1}{6-1} \times [(62-80)^2 + (78-80)^2 + (89-80)^2 + (95-80)^2 + (95-80)^2 + (137-80)^2]}[/tex]

Thus, the test **statistic value** is 0.94.

Compute the p-value of the test as follows:

p-value = p(tₙ₋₁ < t)

p-value = p(t₆₋₁ < t)

p-value = p(t₅ < t)

*Make use of a t-table.

As a result, the test has a p-value of 0.1515.

Rule of decision:

The null hypothesis will be rejected if the **p**-**value** of the test is less than the **significance** threshold, and vice versa.

p-value = 0.1515 > α = 0.05

At 5% significance, the **null** **hypothesis** will not be rejected.
