what is the probability of drawing at least one ace when you draw from a standard deck 25 times? ( the card is replaced each time you draw, so there are always 52 cards in the deck.)
The probability of drawing at least one ace when you draw from a standard deck 25 times is 0.8648
Number of Aces in deck = 4
The probability that they pick no ace in one trail
= (52 - 4) / 52
= 48 / 52
= 12 / 13
The probability that the picks no ace in 25 trials are
= (12/35)²⁵
The probability of drawing at least one ace when we draw from a standard deck 25 times
= 1 - (12/35)²⁵ = 0.8648
Indeed, it is conceivable you could wind up drawing a king rather than a queen from those 52 cards as you might attract a queen on the first go.
Hence the probability of drawing at least one ace when you draw from a standard deck 25 times is 0.8648.

output = -3n +1
Step-by-step explanation:
Given an input/output table for a linear function, you want an expression for the output when the input is n.
Arithmetic sequenceThe input values count up from 1, so we can consider the output values to be the terms of an arithmetic sequence.
The first term of the sequence is a1 = -2 (when n=1).
The common difference of the sequence is d = (-5 -(-2)) = -3.
The general (n-th) term of an arithmetic sequence is given by the formula ...
an = a1 +d(n -1)
For the known values of a1 and d, we find the n-th term to be ...
an = -2 +(-3)(n -1)
an = -2 -3n +3 . . . . . . . eliminate parentheses

as instructed, to find a second solution
y2(x).
x2y'' − xy' + 26y = 0; y1 = x sin(5 ln x)
y2 =
The second solution is: y2(x) = -1 / x¹⁸ + 29x sin(5lnx) ∫ e^(29u) / sin(u) du/5 + Cx sin(5lnx) where C is a constant of integration.
To find a second solution y2(x) for the given differential equation x²y'' - xy' + 26y = 0 with the function y1(x) = x sin(5 ln x), we'll use the reduction of order formula:y2(x) = y1(x) * e^(-∫P(x)dx) * ∫(e^(∫P(x)dx) / y1(x)^2 dx)
First, rewrite the given differential equation in the standard form:
y'' - (1/x)y' + (26/x²)y = 0
From this, we can identify P(x) = -1/x.
Now, calculate the integral of P(x):
∫(-1/x) dx = - ln|x|
Now, apply the reduction of order formula:
y2(x) = x sin(5 ln x) * e^(ln|x|) * ∫(e^(-ln|x|) / (x sin(5 ln x))² dx)
Simplify the equation:
y2(x) = x sin(5 ln x) * x * ∫(1 / x² (x sin(5 ln x))² dx)
y2(x) = x² sin(5 ln x) * ∫(1 / (x² sin²(5 ln x)) dx)
Now, you can solve the remaining integral to find the second solution y2(x) for the given differential equation.
To find the second solution y2(x), we will use the reduction of order method. Let's assume that y2(x) = v(x) y1(x), where v(x) is an unknown function. Then, we can find y2'(x) and y2''(x) as follows:
y2'(x) = v(x) y1'(x) + v'(x) y1(x)
y2''(x) = v(x) y1''(x) + 2v'(x) y1'(x) + v''(x) y1(x)
Substituting y1(x) and its derivatives into the differential equation and using the above expressions for y2(x) and its derivatives, we get:
x^2 (v(x) y1''(x) + 2v'(x) y1'(x) + v''(x) y1(x)) - x(v(x) y1'(x) + v'(x) y1(x)) + 26v(x) y1(x) = 0
Dividing both sides by x^2 y1(x), we obtain:
v(x) y1''(x) + 2v'(x) y1'(x) + (v''(x) + (26/x^2) v(x)) y1(x) - (1/x) v'(x) y1(x) = 0
Since y1(x) is a solution of the differential equation, we have:
x^2 y1''(x) - x y1'(x) + 26y1(x) = 0
Substituting y1(x) and its derivatives into the above equation, we get:
x^2 (5v'(x) cos(5lnx) + (25/x) v(x) sin(5lnx)) - x(v(x) cos(5lnx) + v'(x) x sin(5lnx)) + 26v(x) x sin(5lnx) = 0
Dividing both sides by x sin(5lnx), we obtain:
5x v'(x) + (25/x) v(x) - v'(x) - 5v(x)/x + v'(x) + 26v(x)/x = 0
Simplifying the above expression, we get:
v''(x) + (1/x) v'(x) + (1/x² - 31/x) v(x) = 0
This is a second-order linear homogeneous differential equation with variable coefficients. We can use formula (5) in Section 4.2 to find the second linearly independent solution:
y2(x) = y1(x) ∫ e^(-∫P(x) dx) / y1^2(x) dx
where P(x) = 1/x - 31/x^2. Substituting y1(x) and P(x) into the above formula, we get:
y2(x) = x sin(5lnx) ∫ e^(-∫(1/x - 31/x²) dx) / (x sin(5lnx))² dx
Simplifying the exponent and the denominator, we get:
y2(x) = x sin(5lnx) ∫ e^(31lnx - ln(x)) / x^2sin²(5lnx) dx
y2(x) = x sin(5lnx) ∫ x^30 / sin²(5lnx) dx
Let u = 5lnx, then du/dx = 5/x, and dx = e^(-u)/5 du. Substituting u and dx into the integral, we get:
y2(x) = x sin(5lnx) ∫ e^(30u) / sin²(u) e^(-u) du/5
y2(x) = x sin(5lnx) ∫ e^(29u) / sin²(u) du/5
Using integration by parts, we can find that:
∫ e^(29u) / sin^2(u) du = -e^(29u) / sin(u) - 29 ∫ e^(29u) / sin(u) du + C
where C is a constant of integration. Substituting this result into the expression for y2(x), we get:
y2(x) = -x sin(5lnx) e^(29lnx - 5lnx) / sin(5lnx) - 29x sin(5lnx) ∫ e^(29u) / sin(u) du/5 + Cx sin(5lnx)
Simplifying the first term and using the substitution u = 5lnx, we get:
y2(x) = -x⁶ e^(24lnx) + 29x sin(5lnx) ∫ e^(29u) / sin(u) du/5 + Cx sin(5lnx)
y2(x) = -x⁶ / x^24 + 29x sin(5lnx) ∫ e^(29u) / sin(u) du/5 + Cx sin(5lnx)
y2(x) = -1 / x¹⁸ + 29x sin(5lnx) ∫ e^(29u) / sin(u) du/5 + Cx sin(5lnx)
Therefore, the second solution is: y2(x) = -1 / x¹⁸ + 29x sin(5lnx) ∫ e^(29u) / sin(u) du/5 + Cx sin(5lnx) where C is a constant of integration.

The mean of a normally distributed data as set is 12 and the standard deviation is 2.
____% of the data points lies between 8 and 16.
please help!!! this is super important
Answer:
Step-by-step explanation:
Let x be the random variable representing the data points in the data. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = standard deviation
From the information given,
µ = 12
σ = 2
the probability that the data points lies between 8 and 16 is expressed as
P(8 ≤ x ≤ 16)
For x = 8,
z = (8 - 12)/2 = - 2
Looking at the normal distribution table, the probability corresponding to the z score is 0.023
For x = 16
z = (16 - 12)/2 = 2
Looking at the normal distribution table, the probability corresponding to the z score is 0.98
Therefore,
P(8 ≤ x ≤ 16) = 0.98 - 0.23 = 0.75
The percent of the data points that lies between 8 and 16 is
0.75 × 100 = 75%
The cost of petrol rises by 2 cents a liter. last week a man bought 20 liters at the old price. This week he bought 10 liters at the new price. Altogether, the petrol costs $9.20. What was the old price for 1 liter? 34 POINTS I MARK BRAINLIEST!
Answer:
We suppose that a is the old price in cents
the total cost of 9.20 $ equals 920 cents
so we have 20 liters bought with the old price (a) and 10 liters with the new price (a + 2). This is translated into this equation where a is the old price therefore our quest to be answered
20 xa + 10 x (a + 2) = 920 (cents)
20 xa + 10 xa + 20 = 920
30 xa + 20 = 920
30 xa = 920 - 20
30 xa = 900
a = 900: 30
a = 30 (cents)
therefore the old price for 1 liter of petrol is 30 cents

Step-by-step explanation:
A canoe rental shop is being built near a river. An equation of the line representing the river is y=1/4x+8. Each unit in the coordinate plane corresponds to 100 feet. Approximately how far is the canoe rental shop from the river? Round your answer to the nearest whole foot. The rental shop is at (-3,3).
Answer:
412.3 feet
Step-by-step explanation:
To find the distance from the rental shop to the river, we need to use the formula of the distance between a point and a line:
distance(ax + by + c = 0, (x0, y0)) = |ax0 + by0 + c| / sqrt(a2 + b2)
putting the equation y = (1/4)x + 8 in the form ax + by + c = 0, we have a = 1/4, b = -1 and c = 8, and the point represents x0 = -3 and y0 = 3, so we have:
distance = |(1/4) * (-3) - 1*3 + 8| / sqrt( (1/4)^2 + (-1)^2)
distance = |-3/4 + 5| / 1.0308
distance = 4.25 / 1.0308 = 4.123 units
If each unit in the coordinate plane corresponds to 100 feet, the real distance is:
real distance = distance * 100 = 412.3 feet
The distance between rental shop and river is 412.3 feet.
What is equation of line?A line's equation is an algebraic way of expressing the collection of points that make up a line in a coordinate system.
The many points that collectively make up a line on the coordinate axis are represented as a group of variables (x, y) to create an algebraic equation, also known as an equation of a line.
Given that,
The equation of line,
y = 1/4x + 8.
And the point is (-3,3),
Change the given equation in the form ax + by + c = 0,
x - 4y + 32 = 0
To find the distance,
Use formula of distance between a line and point,
Distance = \(|ax_0+by_0+c|/\sqrt{a^2+b^2}\)
\(= |1(-3) + 3 \times(-4)+ 32|/\sqrt{(-4)^2+1^2\\\\\\\\ \\\\ =(-3-12+32)/\sqrt{17}\\= 17/ \sqrt{17}\)
= 4.123 unit
Since, 1 unit is equal to 100 feet.
Therefore,
4.123 = 412.3 feet.

A box contains 18 tennis balls of which 8 are new (unused). Suppose Serena picks two balls at random, plays with them, then returns them to the box. If Venus then picks three balls from the box at random, what is the probability these three are all new (unused)
The probability that Venus picks three new (unused) balls from the box is 0.1296.Given that a box contains 18 tennis balls of which 8 are new (unused).
We have to find the probability that these three are all new (unused).We know that the balls Serena played with were then returned to the box, so there are 8 new balls left and a total of 19 tennis balls in the box.
Therefore, the probability of picking a new (unused) ball is `8/19`.
Thus, the probability that Venus picks three new (unused) balls from the box is `P(Three new balls) = P(New ball) × P(New ball) × P(New ball) = (4/9) × (8/19) × (8/19) = 0.1296`.Hence, the probability that Venus picks three new (unused) balls from the box is 0.1296.
Summary:A box contains 18 tennis balls of which 8 are new (unused). The probability that Venus picks three new (unused) balls from the box is `P(Three new balls) = P(New ball) × P(New ball) × P(New ball) = (4/9) × (8/19) × (8/19) = 0.1296`.

what is the probability of randomly choosing a 5-letter password for an internet web site that consists of only vowels?
The probability of randomly choosing a 5-letter password for an internet web site that consists of only vowels is approximately 0.00026 (or 0.026%).
There are 5 vowels in the English alphabet (a, e, i, o, u). To create a 5-letter password using only vowels, we have 5 choices for each letter in the password. Therefore, the total number of possible 5-letter passwords made up of only vowels is 5^5 = 3125.
To find the total number of possible 5-letter passwords, we need to consider all 26 letters of the English alphabet. Since there are 26 choices for each letter in the password, the total number of possible 5-letter passwords is 26^5 = 11,881,376.
The probability of randomly choosing a 5-letter password for an internet web site that consists of only vowels is the number of possible 5-letter passwords made up of only vowels divided by the total number of possible 5-letter passwords:
P(password consists of only vowels) = 3125 / 11,881,376
Therefore, the probability of randomly choosing a 5-letter password for an internet web site that consists of only vowels is approximately 0.00026 (or 0.026%).
