Explanation:

Let z be adjacent to angle y, and angle z is inside the triangle on the right.

Adding up the inside angles of any triangle always gets us to 180 degrees.

We'll use this fact to find z.

z+30+50 = 180

z+80 = 180

z = 180-80

z = 100

Angle y and angle z are supplementary angles. They form a straight line of 180 degrees.

So,

y+z = 180

y+100 = 180

y = 180-100

y = 80

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

We can follow the same steps as in the previous section to determine that angle x is 110 degrees.

A shortcut is to use the Remote Interior Angle Theorem.

This theorem says that adding two interior angles will get us the exterior angle that isn't adjacent to either interior angle mentioned.

Notice for instance that angle x is not adjacent to the bottom-left 30 degree angle nor is it adjacent to angle y.

Furthermore, you could use the Remote Interior Angle Theorem to determine the measure of angle y. Note how y = 30+50 = 80. This time the "30" we focus on here is inside the triangle on the right.

It's difficult to say whether the conditions for constructing a t-confidence interval are met based on the information provided. To construct a t-confidence interval, three conditions must be met:

The sampling method must be random. It's not specified in the problem whether the method of selecting the vehicles was random or not, so it's impossible to say whether this condition is met.

The sample size must be large enough. A sample size of 100 vehicles is considered to be large enough for the normal/large sample condition to be met.

The population must be approximately normally distributed or the sample size must be large. Since the problem does not specify anything about the distribution of the population, it is not clear if this condition is met.

The collection of data is gathered and chosen from a statistical population with the use of some prescribed techniques in both statistics and quantitative methodology. Data sets may be divided into two categories: sample and population.

All the components of the data set are included in the population, which also contains quantifiable qualities like mean and standard deviation.

A sample is made up of one or more observations that are taken from the population, and a statistic is what makes a sample quantifiable. The act of sampling is the selection of a sample from a population.

Answer:

108 cm

Step-by-step explanation:

You need to figure out the area of both triangles and then add them to the area of the rectangle. The area of the rectangle can be found like:

12x5=60.

Then, you need to find the are of the triangles. We are told the height of the hexagon is 13cm, and that the height of the rectangle is 5cm. So, the area of the height triangles is 13-5cm and to get the height of the original triangles we will do:

13-5=8/2=4.

Next, we need to find the area of the triangles. That is calculated using the formula a=(1/2)bh. The base is 12 cm (same as the bottom rectangle side) and the height, as found in the previous problem is 4cm. So, what we will do is:

a=(1/2)4*12=24.

The area of one triangle is 24, so we will add that to get the triangles combined area, to 48. The total area of the shape comes by adding all the areas of the shaped found inside it.

60+48=108. So the area of the hexagon is 108 cm.

Answer:

f(x) = - x + 2

Step-by-step explanation:

the equation of a linear function in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

f(0) = 2 means y = 0 when x = 2 and f(5) = - 3 means y = - 3 when x = 5

thus there are 2 points (2, 0 ) and (5, - 3 )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 2 ) and (x₂, y₂ ) = (5, - 3 )

m = [tex]\frac{-3-2}{5-0}[/tex] = [tex]\frac{-5}{5}[/tex] = - 1

the line crosses the y- axis at (0, 2 ) ⇒ c = 2

then

f(x) = - x + 2

What is probability ?

Probability is a measure of the likelihood of an event occurring, expressed as a number between 0 and 1, with 0 indicating that the event will not occur and 1 indicating that the event will occur with certainty. The probability of an event can also be expressed as a percentage or a fraction. It is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

(a) The probability of selecting one red and two black balls is (3/12) * (7/12) * (7/12) = 21/144.

(b) The probability of selecting exactly two black balls is (7/12) * (7/12) * (5/12) = 35/144.

(c) The probability of selecting exactly two balls of the same color is (3/12) * (3/12) + (2/12) * (2/12) + (7/12) * (7/12) = 61/144.

the expression can be simplified to V72√37x323 + V a√z.

V72x323 + Vz = V(72x323 + z)

Since the square roots contain two different terms, we cannot simplify them any further. However, we can remove any perfect squares that are contained inside the square roots. To do this we can factor out the perfect squares from the terms inside the square roots.

For the first square root, 72x323 = 72 x 9 x 37. Since 72 and 9 are both perfect squares, we can factor out these terms to get 72√37x323.

For the second square root, z = a2, where a is a positive real number. We can factor out the perfect square a2 to get a√z.

In a trapezium, the sum of the outer angles is always equal to 360 degrees because, in any convex quadrilateral, the sum of the four angles is consistently 360 degrees. As a trapezium is a type of convex quadrilateral, the sum of its four angles is 360 degrees, regardless of its shape or size.

We can simplify this equation by combining like terms on one side and isolating the variable on the other.

First, combine like terms: x + 5 + 3x - 8 + 5x + 10 + x + 10 = 360

(x + x) + (5 + 10 + 10) + (3x + 5x) = 360

10x + 17 = 360

Then, subtract 17 from both sides to isolate the variable on one side:

10x = 343

Finally, divide both sides by 10 to solve for x:

x = 34.3

So the solution to the equation is x = 34.3

Dianas - 162 cm

Step-by-step explanation:

Median is the mean of the two middle numbers when the numbers are arranged in an ascending order.

We will first have to workout the order when they are placed in ascending order.

Note: Everything here is in ascending order.

Albertos cannot be the shortest as if that happened, the median will not be 160 (Dianas will have to be 179cm as the given range is 21 cm and the mean of Candelas and Bill can never be 160 cm.)

Albertos will have to be second as it cannot be third.( The median will not be 160 when the third number is greater than the second number.)

Now, Dianas will have to be third. ( It can't be first, nor it can be fourth as the median of the height will not be possible to be 160 again without changing the order.)

So, next, obviously, Candelas is first.

So, the order is,

Candelas, Albertos, Dianas, Bill

or,

Candelas , 158, Dianas, 175cm.

Dianas is 162 cm if the mean of 158 cm and Dianas's height is 160 cm.

Candelas's height is 175 - 21 = 154 cm

So the height of Candelas is 154 and height of Dianas is 162.

The horizontal portion of this distance must be 8 meters as its separation from the wheel's center is 10 meters (depending on the radius).

This indicates that the velocity and seat both make angles of 36.87 degrees off vertical and arctan(6/8) over the origin, respectively.
