Therefore, the probability that the absolute cumulative rounding error is at least 2 is bounded by 5/12. Therefore, the probability that the absolute cumulative rounding error is at least 2, as approximated by the Central Limit Theorem, is approximately 0.0456.
a. Chebyshev's Inequality states that for any random variable X with finite mean μ and variance σ^2, the probability of X deviating from its mean by more than k standard deviations is bounded by 1/k^2. In this case, the random variable we are interested in is the absolute cumulative rounding error, |C1 + C2 + ... + C20|, which has mean 0 and variance Var(|C1 + C2 + ... + C20|) = Var(C1) + Var(C2) + ... + Var(C20) = 20/12 = 5/3. Using Chebyshev's Inequality with k = 2 standard deviations, we have:
P(|C1 + C2 + ... + C20| ≥ 2) ≤ Var(|C1 + C2 + ... + C20|) / (2^2)
P(|C1 + C2 + ... + C20| ≥ 2) ≤ 5/12
b. According to the Central Limit Theorem, the sum of independent and identically distributed random variables, such as C1, C2, ..., C20, will be approximately normally distributed as the sample size increases. Since each Ci has mean 0 and variance 1/12, the sum S = C1 + C2 + ... + C20 has mean 0 and variance Var(S) = 20/12 = 5/3. Using the standard normal distribution to approximate S, we have:
P(|S| ≥ 2) ≈ P(|Z| ≥ 2) = 2P(Z ≤ -2) ≈ 2(0.0228) ≈ 0.0456
where Z is a standard normal random variable and we have used a standard normal distribution table or calculator to find P(Z ≤ -2) ≈ 0.0228.

a train travels 16 miles in 20 minutes . at this rate how many minutes will it take to tavel 12 miles
Answer:
15 minutes
Step-by-step explanation:
distance = rate · time
16 = 20r
r = 16/20 or 4/5 miles per minute
12 = 4/5·t
4t = 12·5
t = 60/4 or 15 minutes

Select one or more expressions that together represent all solutions to the equation.
sin(x)=-0.7
Answer:
A. [tex]x_{1} = -44.427^{\circ}\pm n\cdot 360^{\circ}[/tex]
B. [tex]x_{2} = -135.573^{\circ}\pm n\cdot 360^{\circ}[/tex]
Step-by-step explanation:
The negative value of the sine function indicates that [tex]x[/tex] is located at third and fourth quadrants. Besides, this function has a period of 360º. There are two families of solutions:
[tex]x_{1} = \sin^{-1} (-0.7)[/tex]
[tex]x_{1} = -44.427^{\circ}\pm n\cdot 360^{\circ}[/tex]
[tex]x_{2} = \sin^{-1} (-0.7)[/tex]
[tex]x_{2} = -135.573^{\circ}\pm n\cdot 360^{\circ}[/tex]
Hence, right answers are A and B.

Answer:
answer AStep-by-step explanation:
Because this figure is dilated by the factor of 3 we can infer that the figure before dilation was 3 times bigger than the figure now.
so is AC is 5 now then AC before must have been 15
5*3=15
If the angle of A is 37 now then it must have been 111
37*3=111

Answer:
(B) 1/27
Step-by-step explanation:
The terms of the sequence have a common ratio.
(1/8)/(3/16) = (2/16)/(3/16) = 2/3
(1/12)/(1/8) = (2/24)/(3/24) = 2/3
(1/18)/(1/12) = 12/18 = 2/3
The next term will be ...
(1/18)(2/3) = 2/54 = 1/27 . . . . matches choice B

Answer:

Step-by-step explanation:
hope it's helpful to you
Answer:
A) x= -4
Step-by-step explanation:
To solve you must isolate the variable. Do this by using the properties of equality to subtract and divide numbers from both sides of the equation. First, subtract 8x to move all x terms to the right side.
-48=12x
Then, divide both sides by 12
-4=x

1) Find the linear equation from the
graph:
Answer:
y = -1/2 x - 3
Step-by-step explanation:
Use the coordinates from the graph:
(-6, 0) and (0, -3)
Slope m = -3-0/0-(-6)
m = -3/6
m = -1/2
The y-intercept is -3 (point where the line meet the y intercept)
Substitute unto the expression y = mx+c
y = -1/2 x - 3
Hence the required equation is y = -1/2 x - 3

Here are two right-angled triangles.
Given that tan a = tan b
find the value of x.
You must show all your working.
Explanation:
This might not be how you are supposed to do it but,
We can see the two triangles are similar because AA similarity.
We know that the sides are proportional so we can make:
[tex]\frac{x+2}{x}=\frac{4}{3x-1}[/tex]
We get,
[tex]3x^2+5x-2=4x\\3x^2+x-2\\(3x-2)(x+1)=0\\x=2/3, x=-1[/tex]
Because sides can't be negative, x = 2/3
Answer:
x=2/3 = 0.7
Step-by-step explanation:
X+2/x = 4/3x-1
=(X+2)(3x-1)=4x
(x+2)(3x-1)-4x=0
3x²-x+6x-2-4x=0
3x²+x-2=0
3x²+3x-2x-2=0
3x(x+1)-2(x+1)
(x+1)(3x-2)=0
x+1=0
3x-2=0
x=-1 or 2/3
x=2/3 = 0.7
