For the right handed limit we now have x → a + x → a + (note the +) which means that we know will only look at x>a. the left handed limit we have x → a− x → a − (note the -) the means that we will only be looking at x < a

What is the sum of the first 50 terms of the series 2 + 17 + 32 + 47+ ...?
Answer:
[tex]\huge\boxed{18,475}[/tex]
Step-by-step explanation:
The terms of this sum make the arithmetic sequence.
The fomula of a sum of n terms of an arithmetic sequence:
[tex]S_n=\dfrac{[2a_1+(n-1)d]\cdot n}{2}[/tex]
We have
[tex]a_1=2\\d=17-2=32-12=47-32=15\\n=50[/tex]
Substitute:
[tex]S_{50}=\dfrac{[2\cdot2+(50-1)\cdot15]\cdot50}{2}=(4+49\cdot15)\cdot25=(4+735)\cdot25\\\\=739\cdot25=18,475[/tex]

1/x-x/6=2/3 how to answer this
Answer:
x = 0.1
Step-by-step explanation:
1/x - x/6 = 2/3
1/ x - 6/x = 2/3
6/x = 2/3
6x = 2/3
x = 0.1
Answer:
x = 0.2
Step-by-step explanation:
1/x - x/6 = 2/3
=> 1/x - x = 2/3 * 6
=> 1/x - x = 12/3
=> 1/x - x = 4
=> 1/x - x/1 = 4 (x = x/1 )
=> 1 - x/1 = 4 * x
=> -x/1 = 4x - 1
=> -x/1 -4x = -1
=> -5x/1 = -1
=> x = -1/-5
=> x = 0.2 (Because negative / negative = positive)

In this table what is the domain of the function?
Answer:
c. D: {1, 2, 3, 4, 5}
Step-by-step explanation:
The domain of a function includes values of x that are in the given table of values of the given function.
The range, on the other hand, includes all set of values of y, given in the table of values.
Thus, for the table of values above:
Domain would be [1, 2, 3, 4, 5]
Range would be [a, b, c, d, e]
The domain of the function can be represented as:

Suppose X has an exponential distribution with lambda equals 5. Determine the following. Round the answers to 3 decimal places.a) Upper P left-parenthesis Upper X less-than-or-equal-to 0 right-parenthesis equalsb) Upper P left-parenthesis Upper X greater-than-or-equal-to 2 right-parenthesis equalsc) Upper P left-parenthesis Upper X less-than-or-equal-to 1 right-parenthesis equalsd) Upper P left-parenthesis 1 less-than Upper X less-than 2 right-parenthesis equalse) Find the value of x such that Upper P left-parenthesis Upper X less-than x right-parenthesis equals 0.05.
Answer:
Explained below.
Step-by-step explanation:
The random variable X follows an exponential distribution with λ = 5.
The probability density function of X is:
[tex]f_{X}(x)=\lambda\cdot e^{-\lambda\cdot x};\ 0<x<\infty[/tex]
[tex]P(X\leq x)=1-e^{-\lambda\cdot x}\\\\P(X\geq x)=e^{-\lambda\cdot x}[/tex]
(a)
Compute the value of P (X ≤ 0) as follows:
[tex]P(X\leq 0)=1-e^{-\lambda\cdot x}[/tex]
[tex]=1-e^{-5\times 0}\\\\=1-1\\\\=0[/tex]
Thus, the value of P (X ≤ 0) is 0.
(b)
Compute the value of P (X ≥ 2) as follows:
[tex]P(X\geq 2)=e^{-5\times 2}=4.54\times 10^{-5}\approx 0[/tex]
Thus, the value of P (X ≥ 2) is approximately 0.
(c)
Compute the value of P (X ≤ 1) as follows:
[tex]P(X\leq 0)=1-e^{-\lambda\cdot x}[/tex]
[tex]=1-e^{-5\times 1}\\\\=1-0.00674\\\\=0.99326[/tex]
Thus, the value of P (X ≤ 1) is 0.99326.
(d)
Compute the value of P (1 ≤ X ≤ 2) as follows:
[tex]P(1<X<2)=\int\limits^{2}_{1} {5\times e^{-5x}} \, dx \\\\=5\times [\frac{e^{-5x}}{-5}]^{2}_{1} \\\\=5\times [\frac{0-0.00674}{-5}]\\\\=0.0067[/tex]
Thus, the value of P (1 ≤ X ≤ 2) is 0.0067.
(e)
Compute the value of x such that P (X < x) = 0.05 as follows:
[tex]P(X<x)=0.05\\\\\int\limits^{x}_{0} {5\times e^{-5x}} \, dx =0.05\\\\5\times [\frac{e^{-5x}}{-5}]^{x}_{0} =0.05\\\\1-e^{-5x}=0.05\\\\-e^{-5x}=0.95\\\\-5x=\ln(0.95)\\\\-5x=-0.05\\\\x=0.01\\\\[/tex]
Thus, the value of x is 0.01.
Kai took five tests this semester. His scores are listed below.
92, 88, 90, 96, 84
What is the mean absolute deviation of Kai's test scores?
Answer: 16
Step-by-step explanation:
Find the mean absolute deviation of the data:
X : 92, 88, 90, 96, 84
Find the mean(m) of the data:
m = Σ(X) / n
n = number of samples
(92 + 88 + 90 + 96 + 84) / 5
m = 450 / 5
m = 90
Absolute Deviation of each value of the mean:
|x - m| :
|92 - 90| = 2
|88 - 90| = 2
|90 - 90| = 0
|96 - 90| = 6
|84 - 90| = 6
Σ|x - m| = 2 + 2 + 0 + 6 + 6 = 16

On a circle with radius 12 m, what angle would subtend an arc with a length of 7 m?
Answer:
33.42
Step-by-step explanation:
just trust me
33.42 angle would subtend an arc with a length of 7 m.
How do you find the angle of an arc?The angle formed by the arc at the center of the circle is the angle of the arc. Indicated by. m A B ^, A, and B are the endpoints of the arc. You can use the arc length equation to find a measure of the arc angle.
For a circle, the arc length equation is θ times the radius of the circle. The equation for arc length in radians can be expressed as Arc length = θ × r, where θ is in radians. Arc length = θ × (π / 180) × r, where θ is in degrees and L = arc length. θ = central angle of the arc.

Snow play ski park cost $35 entry fee and then $5 per hour. If you have $60, how long can you be at snow play ski park
For $60, you may spend four hours at Snow Play Ski Park.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
Given, Snow plays ski park costs a $35 entry fee and then $5 per hour. If you have $60
Let "x" be the hours you can play in the ski park
Since,
Addition charges = 35
Thus your total expenses to play x hours in the park = 5*x + 35
Since We have only 60$
So,
60 = 5x + 35
=> 5x = 25
=> x = 5
therefore, You can be at a snow play ski park for four hours for $60.

Find X to complete the following ratio. 12:5 = 24:X
Answer:
x = 10
Step-by-step explanation:
This is the answer because:
1) 12:5 is equivalent to the ration 24:10
2) This is because to get 24 you have to multiply 12 and 2 which is 24
3) Next, you have to do the same to the other side to make everything equal. Therefore, you have to multiply 5 with 2 which is 10.
4) Finally, your answer should be 24:10
