There are 36^10 ways that contain only digits and lower-case letters and having the length is 10.
What is password?
A password, also known as a passcode, is private information that typically consists of a string of characters and is used to verify a user's identity.
We have to find the number of ways that contain only digits and lower-case letters and having the length is 10.
Since, there are total 10 digits from '0 to 9' and 26 lower case letters from
'a to z'.
The 10 slots in the password can be anything - digits as lower case letters.
that is,
10 + 26 = 36 options for each slot.
So, the total number of ways are, 36^10.
Hence, there are 36^10 ways that contain only digits and lower-case letters and having the length is 10.

what is the largest integer that is a divisor of $(n 1)(n 3)(n 5)(n 7)(n 9)$ for all positive even integers $n$? (a) 3 (b) 5 (c) 11 (d) 15 (e) 165
The largest integer that is a divisor of (n + 1)(n + 3)(n + 5)(n + 7)(n + 9) for all positive even integers is 15
The correct answer is an option (d)
In this question, we need to find the largest integer that is a divisor of (n + 1)(n + 3)(n + 5)(n + 7)(n + 9) for all positive even integers n.
We can observe that (n + 1), (n + 3), (n + 5), (n + 7) and (n + 9) are 5 consecutive odd integers
In every 5 consecutive odd positive integers, one of them is always divisible by 3 and one of them is always divisible by 5.
This means, (n + 1)(n + 3)(n + 5)(n + 7)(n + 9) will be divisible by both 3 and 5
i.e., (n + 1)(n + 3)(n + 5)(n + 7)(n + 9) will also divisible by 15 (3 * 5 = 15)
Therefore, the largest integer that is a divisior of (n + 1)(n + 3)(n + 5)(n + 7)(n + 9) = 15

Write an equation in point-slope form of the line that passes through the given point and with the given slope (-7,2); m =7
Answer:
Y = 7x + 51
Step-by-step explanation:
Point-slope form is in this form: y = mx + b where b is the y-intercept and m is the slope. We have the slope, and we already have a point that must be on the line. The only thing we need is the y-intercept, so we can plug in the given point and the slope to solve for b.
Plug in (-7, 2) for x and y and the slope(7) for m. This gives: [tex]2 = 7*-7 + b[/tex], or [tex]2 = -49 + b[/tex]. Now add 49 to both sides to isolate x, and we get that [tex]b = 51[/tex]. We have everything we need for the equation now, so plug in the slope and y-intercept for m and b, giving us y = 7x + 51.\

What are coordinates?A coordinate system in geometry is a method for determining the precise location of points or other geometrical objects on a manifold, such as Euclidean space, using one or more numbers, or coordinates.
You do the reverse to determine a point's coordinates in a coordinate system.
Start at the point, then move up or down a vertical line until you reach the x-axis. Your x-coordinate is shown there.
To find the y-coordinate, repeat the previous step while adhering to a horizontal line.
So, we must discover the halfway point between Lan's house and Joe's house in order to get the diner's coordinates.
The following equation will determine the midway between any two points:
M(x1 + x2/2, y1 + y2/2)
There are (4, 4), the point, and the point replaces the specified values:

How to find the value of c in the expression?An expression obtained from the square of the binomial equation is a perfect square trinomial.
In other words, perfect square trinomials are algebraic expressions with three terms that are obtained by multiplying a binomial with the same binomial.
If a trinomial is in the form ax² + bx + c is said to be a perfect square, if and only if it satisfies the condition b² = 4ac.
Therefore,
x² + 24x + c
where
a = 1b = 24c = ?Therefore,
b² = 4ac
24² = 4 × 1 × c
4c = 576
divide both sides by 4
c = 576 / 4
c = 144

c = 144
The perfect squared trinomial as a perfect binomial is as follows:

At a confidence interval of 95%, if a polling result states that a president has an approval rating of 55%, the value of a margin of error of x is 1.534%.
In the given question, at a confidence interval of 95%, if a polling result states that a president has an approval rating of 55%, with a margin of error of x, then we have to explain how should we interpret that.
The given confidence interval = 95%.
We can write it as CI = 0.95.
An approval rating is 55%.
We can write it as(p) = 0.55
A margin of error is x.
Let the value of sample size n = 1000.
So the margin of error;
ME = z× {p(1-p)}/√n
The value of z for confidence interval of 95% is 1.96.
Now putting the value
x = 1.96× {0.55(1-0.55)}/√1000
x = 1.96× {0.55×0.45}/31.623
x = 1.96× 0.2475/31.623
x = 1.96×0.00783
x = 0.01534

A combination is a choice made in mathematics from a group of different elements when the order of the choices is irrelevant (unlike permutations). For instance, if three fruits, such as an apple, an orange, and a pear, are supplied, there are three possible pairings of the two: an apple and a pear. Formally speaking, a k-combination of a set S is a subset of S's k unique components. In other words, two combinations are the same if and only if they have the same members. (It is not important how the individuals in each set are arranged.) The quantity of k-combinations for a set with n components

The mean and standard deviation of sampling distribution are 0.0187 and 0.010 respectively
The mean is a measure of location which tells us the average of observation.
Standard deviation tells us how dispersed a data is or how much variation our data contains.
According to question,
The population size : N = 1500
Number of fraudulent in a month : 28
Population proportion : P = 28/1500
=> P = 0.0187
Sample size: n = 180
Sample proportion : p = 28 / 180

Therefore The mean of sampling distribution for the sample size 28,
μ = P

Applying the formula of the lateral surface area of a cylinder, the number of gallons needed to paint the top and the lateral surface is: 314,901 gallons.
What is the Lateral Surface Area of a Cylinder?The lateral surface area of a cylinder = 2πrh, where h is the height, r is the radius of the cylinder.
Given the following:
Height of the cylinder (h) = 24 yardsDiameter = 3 yardsRadius (r) = 1/2(diameter) = 1/2(3) = 1.5 yardsLateral surface area of the cylinder = 2 × π × 1.5 × 24 = 226.19 yards²
Area of the top = area of circle = πr² = π(1.5²) = 7.07 yards²
Area to be painted = 226.19 + 7.07 = 233.26 yards²
Convert square yards to square feet:
1 square yard = 1 square feet
233.26 square yards = 2099.34 square feet

Answer:
If 6a = 5b then the ratio of 2a : 7b is 5 : 21
Explanation:
Given that 6a = 5b
We have to find the ratio of 2a : 7b
Let us first solve the given expression and find values of a and b
6a = 5b
So we have found that a = 5 and b = 6
Finding ratio of 2a : 7b
2a : 7b = 2(5) : 7(6)
2a : 7b = 10 : 42
On simplifying to lowest terms,
2a : 7b = 5 : 21
Thus the ratio of 2a : 7b is 5 : 21
A circle has a circumference of 6. It has an arc of length 1. What is the central angle of the arc, in degrees?
Answer:
60 degrees
Step-by-step explanation:
The arc length is 1/6th of the total ....the angle will be 1/6th of the total 360° of the circle
1/6th X 360 = 60 °
Answer:
60 degrees
Step-by-step explanation:
1.) Figure out which portion of the circle that the arc is. Since the total circumference is 6, and the arc is 1, that means that the arc is 1/6 of the circle.
2.) Now, figure out the measure of the angle. Since the total angle measure in a circle is 360 degrees, we multiply 1/6*360 to figure out the measure. This is equal to 60 degrees.
