The angle relationships that is supplementary is angle 1 and angle 5.

Supplementary angles are those angles that sum up to 180 degrees.

In other words, supplementary angles refer to the pair of angles that always sum up to 180°.

Alternate exterior angles are congruent to each other.

Therefore, ∠1 and ∠4 are not supplementary angles.

Hence,

m∠4 =m∠1

m∠4 = 85°

Consecutive interior angles are supplementary. That is they sum up to 180 degrees.

m∠1 = 43°

m∠5 = 180 - 43

m∠5 = 137°

Therefore, ∠1 and ∠5 are supplementary angles.

the solution to the pair of equations is u = (1,1) and v = (1,0).

u + 3v = (2,1)

3u + v = (3,2)

u = (1,1) and v = (1,0)

The first equation can be written as:

u + 3v = (2,1)

We can rewrite this equation as:

u + 3(1,0) = (2,1)

By substituting the values of i and j, we can solve for u:

u + (3,0) = (2,1)

u = (2-3,1) = (-1,1)

Now, we can substitute the value of u in the second equation:

(1,1) + v = (3,2)

By subtracting (11) on both sides, we can solve for v:

v = (3-1,2-1) = (2,1)

Therefore, the solution to the pair of equations is u = (1,1) and v = (1,0).

Answer:

x = 42 and y = 92

Step-by-step explanation:

Since there are parallel lines, then

x = 42 ( Alternate angles )

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

134° is an external angle to the triangle, thus

x + y = 134 , that is

42 + y = 134 ( subtract 42 from both sides )

y = 92

----------------------------------------------------

(b)

The sum of the interior angles of a polygon are

sum = 180° (n - 2) ← n is the number of sides

Here n = 7, thus

sum = 180° × 5 = 900°

Following the elimination process the solution of the given system of equations is \((2, -4)\). Hence option B is correct.

The given system of equations is:

2x + 3y = −8   ....(i)

3x + y = 2 ----(ii)

To solve this system by using the elimination method,

Multiply 3 both sides in equation (ii) we get,

9x + 3y = 6  ....(iii)

Subtract (iii) from (i) we get,

2x + 3y - (9x + 3y ) = -8 -6

-7x = -14

Dividing both  sides by -7 we get,

x = 2

Put the value of x into equation (ii),

6 + y = 2

y = -4

Hence,

The solution of the system is \((2, -4)\) which is option B.

Answer:  A verticle line does not have a slope.

Step-by-step explanation:  Slope is the rate of change of y for each change in x.  y = 2x is a line with slope of 2.  Each time x is incremented by 1, y will increase by twice (2x) that amount.  There is no slope to a verticle line, unless you want to call it infinite.  The value of y is not defined by x.

The simplification of the [(2y² - 7y - 15)]/[(3y²-8y - 3] x (9y² - 1)/(4y² - 9) + (y² + 3y - 10)/(2y² - 9y + 9) will be (4y² - 13y - 5)/[(y - 3)(2y - 3)].

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

For comparing three treatments using a one-way fixed effects model, the required sample size (n) is 2.5088

we need to consider the desired power level, significance level, effect size (∆), and the variance (σ²). In this scenario, we want at least 80% power at the 5% significance level, with treatment means that differ by 100 - ∆, 100, and 100 + ∆, where ∆ = 5. The variance is given as σ² = 10.

To calculate the sample size, we can use power analysis based on the F-test. The formula for sample size in this case is:

n = 2 * [(Zα/2 + Zβ)² * σ²] / ∆²

where Zα/2 is the critical value for the desired significance level (5% or 0.05), and Zβ is the critical value for the desired power level (80% or 0.80).

Plugging in the values, we get:

n = 2 * [(1.96 + 0.84)² * 10] / 5²

n = 2 * [(2.80)² * 10] / 25

n = 2 * 7.84 * 10 / 25

n = 6.272 * 10 / 25

n = 2.5088

Rounding up to the nearest whole number, the required sample size (n) is 3.

Therefore, the sample size must be at least 3 in order to achieve at least 80% power at the 5% significance level for comparing the three treatments using a one-way fixed effects model.

Plant 1 grew 3.5 inches over 6 weeks.

Plant 2 grew ~ 2.25 inches over 6 weeks.

Plant 3 grew 4 inches over 6 weeks.

The statement "the expected value of an unbiased estimator is equal to the parameter whose value is being estimated" is true.

An estimator is a function of the sample data used to estimate the value of a population parameter. An estimator is said to be unbiased if its expected value is equal to the true value of the population parameter. In other words, if we were to repeatedly take samples from the population and calculate the estimator for each sample, the average value of the estimator over all the samples would be equal to the true value of the population parameter. The expected value of an unbiased estimator is a key property because it ensures that the estimator is not systematically overestimating or underestimating the population parameter. Instead, the estimator provides an unbiased estimate of the population parameter on average across all possible samples. It is important to note that not all estimators are unbiased. Biased estimators may systematically overestimate or underestimate the population parameter, leading to incorrect conclusions. Therefore, unbiasedness is a desirable property for an estimator to have.

1. times both sides by r-3

t(r-3) = r

= tr - 3t = r

2. add 3t to both sides

tr = 3t + r

3. minus r

4. factorise out r

r(t-1)=3t

5. divide by t-1

The height of the rectangle is 16.6 millimeters.

To find the height of a rectangle, we can use the formula for the perimeter of a rectangle, which states that the perimeter is equal to twice the sum of its length and width. In this case, the base of the rectangle is given as 15.8 millimeters, and the perimeter is given as 64.8 millimeters.

Let's denote the height of the rectangle as h. Using the formula, we can express the given information as:

Perimeter = 2 × (Base + Height)

Substituting the given values, we have:

64.8 = 2 × (15.8 + h)

To solve for h, we first simplify the equation by multiplying the values inside the parentheses:

64.8 = 2 × 15.8 + 2 × h

Next, we simplify further:

64.8 = 31.6 + 2h

Subtracting 31.6 from both sides:

64.8 - 31.6 = 2h

33.2 = 2h

To isolate h, we divide both sides by 2:

33.2/2 = h

16.6 = h
