If P(n) and Q(n) are polynomials of degree j and k, respectively, then the series
Infinite
Σ P(n)/Q(n)
n=1
converges if j < k − 1 and diverges if j ≥ k – 1.
Use the polynomial test given above to determine whether the series converges or diverges.
Infinite
Σ 1/(n)^8 +7
n=1
O converges
Odiverges
Answer:
converges
Step-by-step explanation:
well the two polynomials in the series are 1 and n^8 (I'm assuming the +7 is not in the decimal but it seems to not matter). The degree of the polynomial 1 is 0 which can be represented by 1x^0. The second polynomial in the denominator has a degree of 8. So j = 0 and k = 8. Since 0 < (8-1)
0 < 7 the series converges

The probability that a randomly selected person with a kidney stone will take longer than 16 days to pass it is 0.15866 , the minimum number for the upper quarter of the time to pass a kidney stone days is 14.4 .
What is Probability ?Probability is the measure of likeliness of an event to happen
Let X denote the time to pass the kidney stone.
The random variable X follows normal Distribution
mean = 12 days days
standard deviation = 4 days
The distribution of X is X - N ( 12 , 4)
The probability that a randomly selected person with a kidney stone will take longer than 16 days to pass it is
P ( X > 16) = 1 - P( X ≤ 16)
= 1 - P( Z ≤ (16-12)/4)
= 1 - P ( Z ≤ 1 )
= 1 - 0.84134

Find all (a, b, c, d) in R4
such that the given set is orthogonal.
{(1, 2, 1, 0), (1, −1, 1, 3), (2, −1, 0, 1), (a, b, c, d)}
Answer:
[tex]\left[\begin{array}{}0&\\1&\\-2&\\1&\end{array}\right][/tex] t in R Correct option (B)
Step-by-step explanation:
Orthogonal vectors : We say that 2 vectors are orthogonal if they are perpendicular to each other. i.e. the dot product of the two vectors is zero.
Dot product : The dot product of two vectors is equal to the sum of the products of the individual components of the two vectors.
for the given vector (a, b, c, d) to be orthogonal its dot product with each vector must be 0
therefore (1, 2, 1, 0).(a, b, c, d) = 0
a + 2b+ c+ 0 = 0 -------- (i)
similarly (1, -1, 1, 3 ).(a, b, c, d) = 0
a - b + c + 3d = 0 -------- (ii)
(2, -1, 0, 1).(a, b, c, d) = 0
2a - b + 0 + d = 0 ---------- (iii)
subtracting equation (i) from (ii)
a - b + c + 3d - a - 2b - c - 0 = 0
-3b + 3d = 0
b = d
substituting b = d in (iii)
2a + b + 0 + b = 0
2a + 2b = 0
a = 0
substituting a = 0 , b = d in (i)
0 + 2d + c + 0 = 0
c = -2d
thus for any t ∈ R, vector(0, t, -2t, t) will make the given set orthogonal
the above vector can also be written as (0, 1, -2, 1)
therefor option B is correct

You loaned a friend $100 and will charge him 5% annual simple interest when he pay it back. What is the amount of interest after 3 years?
What is simple interest?Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.
The interest is given as
I = (P × R × T) / 100
Where, P is the initial amount, R is simple interest rate, and T is the time.
We have
P = $100
R = 5%
T = 3 years
Then the interest will be
I = (100 × 5 × 3) / 100

a/sin(63) = 3/sin(49)
Multiply both sides by sin(63)
a = sin(63) * 3/sin(49)

Using it's concept, it is found that the probability that the button is either pink or blue is:
[tex]p = \frac{26}{29}[/tex]
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, we have that:
There are x yellow buttons.There are y blue bottons.There are z pink buttons.There are six times as many pink buttons as yellow books, hence:
z = 6x.
Considering the ratio of yellow buttons to blue buttons, we have that:
[tex]\frac{x}{y} = \frac{3}{8}[/tex]
3y = 8x
[tex]y = \frac{8x}{3}[/tex]
The total number of buttons is given by:
[tex]T = x + \frac{8x}{3} + 6x[/tex]
[tex]T = \frac{29x}{3}[/tex]
The number of pink or blue is given by:

Michael designed an activity plan for the next week he determined that they could run at 6 miles per hour and walk at 3 mph if Michael dedicates 12 hours in the week to travel a total distance of 48 miles how many hours does Michael plan on running and walking
Answer:
Run 4 hours, Walk 8 hours.
Step-by-step explanation:
Let R be the running time
Let W be the walking time
Distance = Speed x Time
48 = 6R + 3W (equation 1)
12 = R + W (equation 2)
We will use elimination method to solve for these simulteanous equations.
Multiply Equation 2 by 3.
12x3 = 3(R+W)
36 = 3R + 3W (equation 3)
now subtract equation 3 from equation 1.
48-36 = 6R - 3R + 3W - 3W
12 = 3R
R = 12/3
= 4hours
now Substitute R into equation 2.
12 = 4 + W
W = 12 - 4
= 8
Therefore Michael plan to run for 4 hours and walk for 8 hours.
A manufacturing company regularly conducts quality control checks at specified periods on the products it manufactures. Historically, the failure rate for LED light bulbs that the company
manufactures is 14%. Suppose a random sample of 10 LED light bulbs is selected. Complete parts (a) through (d) below.
a. What is the probability that none of the LED light bulbs are defective?
The probability that none of the LED light bulbs are defective is
(Type an integer or a decint. Round to four decimal places as needed.)
A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. The probability that none of the LED light bulbs are defective is 0.2213.
What is Binomial distribution?A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. It is given by the formula,
P(x) = ⁿCₓ (pˣ) (q⁽ⁿ⁻ˣ⁾)
Where,
x is the number of successes needed,
n is the number of trials or sample size,
p is the probability of a single success, and
q is the probability of a single failure.
Given the probability of a bulb being a failure is 14%, therefore, the probability of bulb passing the quality check is 86%.
Let the probability of success be defined as 0.14 for binomial distribution, and the probability for failure be 0.86. Therefore, The probability that none of the LED light bulbs are defective is
P(x=0) = ¹⁰C₀ (0.14)⁰ (0.86)¹⁰ = 0.2213
Hence, The probability that none of the LED light bulbs are defective is 0.2213.
