2x

Answers

Answer:

60°

Step-by-step explanation:

The sum of the angles in any quadrilateral is 360°. In a parallelogram the sum of neighboring angles is 180°. Therefore:

2x + x = 180°

3x = 180°

x = 60°

The  value of x is 60.

What is properties of parallelogram?Parallel sides define an object.Congruent opposites are present.Angles at opposites are congruent.Consecutive angles on the same side called supplementary angles.A parallelogram is divided into two congruent triangles by each of its diagonals.A parallelogram's diagonals cut each other in half.

Given:

Angles x, x, 2x, 2x.

Using the property of parallelogram, the adjacent angles of parallelogram sum to 180.

x+ 2x= 180

3x= 180

x= 180/3

x= 60

Hence, the value of x is 60.

Answers

answer :

obtuse angle

explanation : no cap

Answer:

D : Obtuse

Step-by-step explanation:

A right angle is 90 degrees.

An acute and obtuse angle are found by looking at the angle between the sides being looked at.

If the angle is GREATER i.e. Angle > 90 , then it is obtuse.

If the angle is LESS THAN i.e. Angle < 90 , then it is acute.

This angle is apparently greater than 90 degrees and therefore is obtuse.

During a thunderstorm, 4
inches of rain fell in 2 1/2
hours. What was the rate of rainfall in inches per hour?

Answers

Answer: 1.6 in per hour

Answer:

hourly rate.

Step-by-step explanation:

As others have noted, it is a simple mathematical division problem (4/2.5) and the average is 1.6 inches per hour.

However, if this is for sizing civil works such as culverts or plumbing storm water drainage systems to mitigate flooding, the highest rate per hour must be known and usually the highest ten minutes rainfall rate expressed as an hourly rate.

For example, if 4.0 inches fell over that 2.5 hours, nothing says that a rain band did not dump 3 inches in the first hour, (3 inches per hour cumulative) or 0.75 inches in a ten minute period (4.5 inches per hour rate), with the remainder of the storm tapering off to lesser rates. So the average is correct, but the peak hour is much more important for practical purposes.

Nine voltage measurements in a circuit have produced the following values: 12.09, 12.05, 11.94, 11.99, 12.12, 12.05, 12.02, 11.95, 12.14. If the standard deviation for the above data set is 0.07V, determine whether any values can be rejected. (5 Points)

Answers

Answer:

we can not reject any value

Step-by-step explanation: From data we can test the highest and the lowest value to evaluate if one of these values are out of certain confidence Interval

If we established CI = 95 % then  α = 5 % and  α/2 = 0,025

From data we find the mean of the values

μ₀  = 12,03   and σ = 0,07

From z table we find z score for 0,025 is  z(c) = ± 1,96

So limits of our CI are:

12,03 + 1,96 =  13,99

12,03 - 1,96 = 10,07

And all our values are within  ( 10,07 , 13,99)

So we can not reject any value

Identify which of these types of sampling is​ used: random,​ systematic, convenience,​ stratified, or cluster. To determine her stress level​, Charlotte divides up her day into three​ parts: morning,​ afternoon, and evening. She then measures her stress level at 2 randomly selected times during each part of the day.

Answers

Answer:

stratified sampling

Step-by-step explanation:

Note, in the stratified sampling sample method, the population is divided into smaller strata or smaller groups, and then a sample is selected randomly.

In this scenario, the population is a day (24 hours), so dividing the population (day) into three parts; morning, afternoon, and evening represents the various strata. Hence, since Charlotte, the researcher measures her stress level at 2 randomly selected times during each part of the day, she would be using the stratified sampling method.

Find a Point-Slope equation for a line containing the given point and having the given slope.

(5, -1), m =1/5

Answers

Answer:

The point-slope equation for a line is:

[tex]y-\left(-1\right)=\frac{1}{5}\left(x-5\right)[/tex]

Step-by-step explanation:

Given

The point = (5, -1)m = 1/5

We know that the point-slope form is

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line

substituting the values m = 1/5 and the point (5, -1)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-\left(-1\right)=\frac{1}{5}\left(x-5\right)[/tex]

Thus, the point-slope equation for a line is:

[tex]y-\left(-1\right)=\frac{1}{5}\left(x-5\right)[/tex]

Casual walkers in rural and urban areas in Alberta may enjoy the vibrant purple flowers of the purple loosestrife plant, but the trained eye of an ecologist sees the threat this invasive species poses.Purple Loosestrife InvasionPurple loosestrife was not always seen in and around Alberta. In fact, it wasnt found anywhere in North America before the 1800s.During the 1800s, ships transporting goods around the world were sometimes without cargo for a time, particularly when they were heading to collect a new load. Wooden ships dont balance well when they are empty, so when they were without a cargo, they were often filled with ballast instead.How does this relate to purple loosestrife in Alberta? Well, purple loosestrife is a naturally-occurring plant in Europe and Asia, which means that their seeds may become mixed in with the soils found there. Ships sailing from Europe and Asia to North America without cargo often used soil as ballast to maintain the balance of the ships, and then dumped the soil when they arrived to pick up their cargo. It is believed that this dumped soil introduced the purple loosestrife species to Canada.It may also be the case that early settlers brought purple loosestrife with them when they settled Canadas west.Purple Loosestrife: A Not-So-Welcome IntroductionSo whats the big deal about having purple loosestrife in Alberta? Well, purple loosestrife is not a species of plant that occurs naturally in the province- it is an introduced species. Organisms that dont occur naturally in an area but are instead brought from elsewhere are categorized as introduced species.Again, whats the big deal about that? Well, organisms that are introduced to an ecosystem may become invasive - think: invader! An invasive species is defined as any organism that reproduces so quickly or grows so aggressively that it becomes a problem for the other organisms around it. Invasive plant species tend to outcompete local plants for resources such as sunlight, water and root space. In this way, invasive species can harm ecosystems by taking over, disrupting food webs and decreasing biodiversity.Purple loosestrife has invaded local wetlands and is often found growing unchecked in other wet areas of the city. It flowers prolifically, producing millions of seeds each year. These seeds have many vectors of dispersal, for example, they may be blown to new places by the wind (aerochory), travel along with moving water (hydrochory), hitchhike in animals fur or be deposited in animal waste (zoochory), and even planted intentionally by humans.Purple Loosestrife: Super-plant!Purple loosestrife grows in clumps with a dense root system that extends underground like a living mat - its like a super villain, soaking up nutrients and taking over the space where other plants might grow. In wetlands, waterflow can be disrupted as waterways become clogged.Over time, purple loosestrife becomes the dominant plant in an area and other plants disappear. This disrupts the food web because animals that only feed on the plants that disappear, disappear too. Once a plant disappears and the animals that feed on that plant disappear, there is a ripple effect along the food chain. Animals that can adapt to their food source disappearing by switching to a different food source will survive, but those that dont adapt either move to a different habitat or die.Waging War on Purple LoosestrifeIn Alberta, purple loosestrife is classified as prohibited noxious, which means that it is not allowed to be planted and any plants that are found must be destroyed. In many Alberta cities, crews are sent out to dig out and destroy clumps of loosestrife that are reported.Another way that purple loosestrife has been kept in check across Canada is through the use of biological controls (when one living organism is used to control another). Beetles such as the black-margined loosestrife beetle feed on purple loosestrife, so they are the plants natural enemies - perfect for biological control. Releasing the black-margined loosestrife beetle can reduce the purple loosestrife population in an area significantly. When an invasive species is controlled, often the original plants can re-populate and the ecosystem can return to a balanced state.Using Text Features to Predict InformationScan the nonfiction text to find the text features listed.
