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.

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

The circumference of a circle is 9.04cm.
Find the length of the diameter.
Give your answer rounded to 2 DP.​

Answers

C=pi x D
9.04= pi D
D=9.04/pi
or= 2.87
Question:-

The circumference of a circle is 9.04 cm. Find the length of the diameter.

Solution:-

Let the radius of a circle be r cm.

We know the formula of circumference of a circle is 2πr.

ATQ ,

2πr = 9.04

2 × [tex] \frac{22}{7} [/tex] × r = 9.04

[tex] \frac{44}{7} [/tex] × r = 9.04

r = [tex] \frac{9.04 \: × \: 7}{44} [/tex]

r = [tex] \frac{63.28}{44} [/tex]

r = 1.438

Now, as we have to find the length of the diameter ,

So, we know, Diameter (d) = 2 × radius (r)

[tex] \therefore [/tex] d = 2r

Hence, d = 2 × 1.438 ( r = 1.438 )

d = 2.876

d = 2.88 ( approx )

The length of the diameter is 2.88 cm. [Answer]

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.
