Answer:

A. Equilateral,

D. Acute,

F. Isosceles.

Step-by-step explanation:

We have been given an image of a triangle and we are asked to classify our given triangle.

We can see from our given triangle that its all angles are equal, therefore, our triangle is an equilateral triangle and option A is a correct choice.

Since all the angles of an equilateral triangles equal to 60 degrees and our triangle has no angle that measures 90 degrees or more than 90 degrees, therefore, our triangle is neither right nor obtuse triangle and option B and C are not correct.

Since all the angles of an equilateral triangles equal to 60 degrees, therefore, our triangle is also acute triangle and option D is the correct choice.

Since all sides of a scalene triangle are unequal, while all sides of an equilateral are equal, therefore, our triangle is not a scalene triangle and option E is not correct.

An isosceles triangle has two equal sides, while an equilateral has three equal sides, therefore, every equilateral triangle is isosceles and option F is correct.

a triangle has an area of 38.4cm.the height of the triangle is 12.8cm.what is the length of the base of the triangle

Solnce55 [7]

Answer: 6 cm

Step-by-step explanation:

Use equation for area of triangle

A=a*h/2

a*h=2A

a=2A/h

where a represents base of triangle

h represents height of triangle.

h=12.8 cm

A=38.4 cm²

a=2A/h=2*38.4 cm²/12.8 cm=76.8cm²/12.8cm= 6 cm

What is the equation of the translated function, g(x), if f(x) = x2?

Eddi Din [679]

All of these would be translated versions of f(x).

A translated version is simply one in which the base equation is used and then moved. Each of these equations are quadratics with a starting term of x^2. All of them move up and down or side to side in some way and direction, but all of them would be translated versions of that graph.

The Hamden board of education wants to know how the community feels about building a new media center for the middle school. The

Aleks [24]

According to the statement above, The Hamden board of education called every tenth person on the registration list. So let's analyze each case:

The sample is not randomly chosen (FALSE)

Given that the statement doesn't tell us anything about the way they choose the sample, it is reasonable to conclude that this is a randomly chosen. They called every tenth person on the registration list until the number of people was 40.

The sample should be larger to give more reliable information (TRUE)

You did not have to use mathematics to determine that you would need more information to get a conclusion. You must increase the sample, that is, the sample must be larger to give a reliable information.

The sample size is too large to make inferences (False)

This is explained in the previous item. If the sample should be lager is because the size is not too large.

The sample size is too small to represent the population (TRUE

This is true because 40 voters represent barely 0.5% of the entire list. This list has 7300 voters, so getting the conclusion from this sample doesn't provide with a strong conclusion.

The sample size is too small and will show larger variation. (FALSE)

Although the sample size is too small, the sample size not necessarily will show variation. In fact, it is possible that it does not show any variation and most of the people feel well about building a new media center for the middle school but it doesn't mean that the whole community does.

The sample is invalid because it randomly chooses voters. (FALSE)

It is false because in probability studies the sample is chosen randomly, so you get conclusions about the whole population always taking samples that represent the population as a whole.

The sample size is too small and can lead to false inferences (TRUE)

You can get false conclusions given that the sample size is too small. It's important to note that the sample size supports the conclusion of the study, so the sample must increase to have a reliable study.

Which situation could be represented by the graph?

Y_Kistochka [10]

Answer:

A program at a community college can be completed in no fewer than 8 months, but must be completed in less than 11 months.

Step-by-step explanation:

1. The closed dot means the number is equal to and the open dot means the number is less/ greater than

2. The line goes right from the 8 with a closed dot, making x greater than or equal to 8

3. The line goes left from the 11 with an open dot, making x less than ll

4. This means the number must be equal to or greater than 8, and less than 11
