What’s the answer?????
Answer:
(1,1)
Step-by-step explanation:
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.

Answer:
B. 315 meters
Step-by-step explanation:
The length of the longer side of the lot on drawing = 6.3 cm
Given a scale of 1cm : 50 m
Let the length of the longer side be represented as x.
Therefore, the actual length of the longer side will be calculated as follows:
1:50 = 6.3:x
1/50 = 6.3/x
Cross multiply
x*1 = 50*6.3
x = 315
Actual length of the longer side of the lot = 315 meters
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.

Cuál es la fuerza total que ejerce 3 personas empujando una carreta? F1 = 30 N, F2 = 45 N, F3 = 38 N?
Respuesta:
113 N
Explicación paso a paso:
Las fuerzas ejercidas se dan como:
F1 = 30 N
F2 = 45 N
F3 = 38 N
A partir de los valores de las fuerzas ejercidas, podemos observar que todas las fuerzas están en la misma dirección; Dado que la fuerza total ejercida es un sol de las 3 fuerzas:
F1 + F2 + F3
(30N + 45N + 38N) = 113 N

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.

If 44% of the students in a certain collage are female and there are 2640 female students what is the total number of students in the total students
Answer:Total number of students=6000 students
Step-by-step explanation:
Number of female students =2640
Percentage of female students=44%
But
Percentage of female students x Total number of students =Number of female students
Therefore
Total number of students=Number of female students / Percentage of female students
Total number of students=2640/44% =6000 students

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

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