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.
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.

What is the relationship between a and b
A) vertical angles
B)complementary angles
C)supplementary angles
D)Non of the above
Answer:
Vertical Angles
Step-by-step explanation:
Any opposite angles caused by two intersecting lines are vertical angles.
Any two adjacent angles caused by vertical lines or two angles that equal 180° are supplementary angles.
Two angles that make 90° in all are complementary angles.

PLEASE HELP ME *begs*
Answer: 2
Step-by-step explanation: so just plug in the numbers first 3(4)-2(-1)-9+3(-1)
then easy just solve remember two negatives equal a positive so 3 times the 4 is 12 and then -2 and -1 is just a positive 2 then minus the 9 and then add -3 because a positive and a negative is a negative and written out that all is 12+2-9+(-3) then it's 14-9 which is 5 then 5+ (-3) is positive 2 so boom lol I hope this helps! let me know if you need any more help! :')

What single percentage change is equivalent to a 11% decrease followed by a 13% decrease
Answer:
24%
Step-by-step explanation:
x-(11/100)x
89/100x
followed by
89/100x-13/100x
76/100x
so the total decrease is calculated as
x-76/100x
(24/100)x
i.e 24% decrease

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
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.

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
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

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)?
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
