Answer:

  z = 134°

Step-by-step explanation:

You want to know the measure of exterior angle z given remote interior angles of the triangle are 77° and 57°.

The exterior angle of a triangle is equal to the sum of the remote interior angles of the triangle. (It is useful to remember this.)

  z = 77° +57°

  z = 134°

__

Additional comment

As you know the value of the interior angle at C will be the supplement of the value of z: (180° -z). Then the sum of the interior angles is ...

  77° +57° +(180°-z) = 180°

Add (z -180°) to both sides of this equation and you get ...

  77° +57° +(180°-z) +(z -180°) = 180° +(z -180°)

  77° +57° = z . . . . simplified

If He rides back home, taking the same route, on a bus that travels at a rate of 40mi/hr. The entire trip takes 3.5 hrs. How far along this route is Terrence’s house from the theater is : 50 mile.

Movie time = 2hrs and 15mins

Let convert the movie time

2hrs and 15mins = 2 15/60 h = 2 1/4 h = 2.25 h

Now let calculate the bus time and the distance

Bus time = Entire time - Walking time

Bus time = 3.5 h - 2. 25 h

Bus time =  1.25 h

Now let calculate the distance

Distance = Speed × Time

Distance =  40mi/hr ×  1.25 h

Distance = 50 mile

Therefore the distance is 50 mile.

The quota sampling produces the same advantages for convenience sampling that stratified random sampling produces for probability sampling.

Sampling:

Sampling is defined as the process in statistical analysis where researchers take a predetermined number of observations from a larger population.

Given,

Here we need to find the type of sampling that produces the same advantages for convenience sampling quota sampling.

Before, move on to the result, first we have to know the details about quota sampling and the probability sampling.

Probability sampling defined as the selection of a sample from a determined number of population, when this selection is based on the principle of randomization, that is, random selection or chance.

In contrast to probability sampling, Quota sampling means a non-probability sampling method in which researchers create a sample involving individuals that represent a population.

Based on these definition we have identified that the method that is best suitable answer for this one is stratified random sampling.

Because the stratified random sampling means, is a probability sampling technique in which the total population is divided into homogenous groups to complete the sampling process.

The slope of the line between the two points defined in the graph is 1/2.

Slope of the line:

The slope of a line is the change in y coordinate with respect to the change in x coordinate.

m = Δy/Δx

Where the net change in y-coordinate is represented by Δy and the net change in x-coordinate is represented by Δx. Where “m” is the slope of a line

Given,

There is a graph presented here.

Through the graph we have identified two points,

They are (3,0) and (-3, -3).

Now we need to find the slope of the line between these points.

Here we consider the values of (x1,y1) as (3,0) and the value of (x2,y2) as (-3,-3).

Through the values we have to identify the slope of the line.

For that, we have to apply the values on the formula,

Then we get,

m = (-3 - 0)/(-3-3)

m = -3/-6

m = 1/2

Therefore, the slope of the line is 1/2.

What is an equation?

An equation is a formula in mathematics that expresses the equality of two expressions by linking them with the equals sign. A polynomial equation is the most common sort of equation. A mathematical equation is akin to a weighted scale. When equal weights of material (for example, grain) are placed in the two pans, the scale is balanced and the weights are said to be equal. To keep the scale in balance, if grain is withdrawn from one pan of the balance, an equal amount of grain must be removed from the other pan. In general, if the identical operation is done on both sides of an equation, it stays balanced.

The required equation is g(x)=x+6, when the parent function is 6 units up

The coordinates of the point M' is (-6,2) when the point M was reflected across x =-2.

Here, assume that there is a point A(a, b). This point is reflected across the line x = -2. When reflected across this line, the value of the y coordinate of this point A will not change, only the value of the x coordinates of the point A will change.

Here, the point M(1,2) is reflected across the line x = -2.

The coordinates of the reflected point M' are (a, b).

The value of will b will remains same as that of the point M.

Now, the location of a,

the distance between the line x = -2 and a will be same as that of the distance between 2 and x =-2 which is 4 units,

So, the location of a will be fours units away from x =-2 and in the opposite direction so, a = -6
