f the quadratic function f(x) = x2^2 is graphed below along with the quadratic function g(x) which of the following could
be a correct equation for g(x)?

Answers

Answer: g(x)= -1/2x^2

Step-by-step explanation: since the parabola is opening downwards it would have to be a negative so all we are left with is g(x)=-2x^2 and g(x)-1/2x^2 and if we go in the calculator and type up each equations you would see our answers is g(x)=-1/2x^2

Check all solutions to the equation. If there are no solutions, check "None."

In a game of luck, a turn consists of a player rolling 121212 fair 666-sided dice. Let X=X=X, equals the number of dice that land showing "111" in a turn. Find the mean and standard deviation of XXX. You may round your answers to the nearest tenth.

Answers

Answer:

The mean of X is 2 and the standard deviation is 1.3.

Step-by-step explanation:

For each dice rolled, there are only two possible outcomes. Either it lands on one, or it does not. The probability of a dice rolled landing on one is independent of any other dice. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

Probability of rolling a 1.

Six sides, so:

[tex]p = \frac{1}{6} = 0.1667[/tex]

12 dices are rolled:

This means that [tex]n = 12[/tex]

Find the mean and standard deviation of X

[tex]E(X) = np = 12*0.1667 = 2[/tex]

[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{12*0.1667*0.8333} = 1.3[/tex]

The mean of X is 2 and the standard deviation is 1.3.

Is this correct please help

Which of the following shows a group of possible angles a triangle could have?

A. 10 degrees, 20 degrees, 190 degrees
B. 30 degrees, 60 degrees, 60 degrees,
C. 60 degrees, 90 degrees, 90 degrees
D. 50 degrees, 60 degrees, 70 degrees

Answers

Answer:

D) 50, 60, 70

Step-by-step explanation:

The reason why it's D since a regular triangle equals up to 180 degrees in total and D is the only one that equals 180.

50+60+70= 180 degrees

Which Statement is true?

Answers

Answer:

All parallelograms are quadrilaterals

Step-by-step explanation:

All parallelograms are quadrilaterals is true statement.

What are Quadrilaterals?

a quadrilateral is a four-sided polygon, having four edges and four corners

A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

All parallelograms are rectangles is not true because all rectangles are parallelograms, but all parallelograms are not rectangles.

All parallelograms are quadrilaterals is true.

All parallelograms are not rhombuses. Parallelograms with non equal adjacent sides are not rhombuses.

All parallelograms are not squares.

Hence, All parallelograms are quadrilaterals is true statement.

What type of triangle is shown in the image?

a triangle with two angles that are thirty degrees, and one angle that is one hundred twenty degrees

Group of answer choices

Acute triangle

Right triangle

Equilateral triangle

Obtuse triangle

Answers

Answer:

the answer is an obtuse triangle

The triangle in the image is an obtuse triangle.

In any triangle, the sum of the three angles is always 180 degrees.

Here, the sum of the two angles is 30 + 30 = 60 degrees.

Now, Adding the 120 degrees angle

= 60 + 120

= 180 degrees, which is consistent with the sum of angles in a triangle.

Now, let's consider the types of triangles:

1. Acute triangle: All three angles in an acute triangle are less than 90 degrees.

2. Right triangle: A right triangle has one angle that measures exactly 90 degrees.

3. Equilateral triangle: An equilateral triangle has all three angles equal to 60 degrees.

4. Obtuse triangle: An obtuse triangle has one angle that is greater than 90 degrees.

Thus, the triangle in the image is an obtuse triangle.

THIS IS THE ANSWER, HAVEN'T GOT A GRADE YET BUT IT'S RIGHTDescribe how social categories, roles, and practices have changed since 1900.Social categories, roles, and practices have changed a lot since 1900, as since then, new countries have been created, new systems have been put in place, conflict has changed the way countries work, as well as many other factors. For example, in the 1900s, women around the world started to advocate more for their rights to vote and have power. In 1979, the UN made gender equality a human right, thus giving women more of a role in society. As time progressed, their social roles and practices, typically as caretakers who dont work or have a say in finance, diminished in importance. This was as a result of the Industrial Revolution increasing the demand for labor, and women being forced to work in factories to support their family. This is just one example of how social categories, roles, and practices have changed since 1900. Another change in social categories, roles, and practices were the surrendering of colonies by colonial powers. This changed the social structure of many countries, and created many new ones that changed social norms in that particular country. For example, in the mid 1900s, African countries were rapidly gaining independence, and were creating new cultures and social structures as a result. The people native to these African countries were suddenly acquiring many more rights than they previously had, changing the social structure drastically. In short, as the times have changed and the economy and political world have called for more change in how things are run, social categories, roles, and practices were abandoned in favor of new methods.
