The sum of the digits of n is 3 if n is the second smallest positive integer that is divisible by every positive integer less than 7
What is least common multiple?
The least common multiple (LCM) of two numbers is the lowest possible number that can be divisible by both numbers.
It can be calculated for two or more numbers as well.
For example, LCM of 10, 2 and 7 is 70.
According to the given question:
Now n must be divisible by every positive integer less than 7, or
1, 2, 3, 4, 5, and 6.
Each number that is divisible by each of these is a multiple of their least common multiple.
LCM (1,2,3,4,5,6) = 60
So each number divisible by these is a multiple of 60.
The smallest multiple of 60 is clearly 60, so the second smallest multiple of 60 is 2 x 60 = 120.
Therefore, the sum of the digits of n is 1+2+0 = 3

The required probability for three numbers rolled on the dice are the sides of a triangle is 31/36.
What is probability?The area of mathematics known as probability studies potential outcomes of events as well as their relative probabilities and distributions. It is based on the likelihood that something will occur. The justification for probability serves as the main foundation for theoretical probability.
Here,
When three dice are rolled, there are 63=216 possible outcomes, or triplets (x, y, z).
Once more, in a triangle, any two sides added together are larger than the third side, or (x+y)>z.
As a result, 186 outcomes or triplets are possible and satisfy this property.
Hence, the required probability is 186/216=31/36.
The required probability is 31/36 for three dice rolls to produce triangle sides.

a license plate consists of 2 letters followed by 4 digits. how many license plates are possible if the 1st digit cannot be 0, and letters and digits may repeat? a) 4,100,625 b) 6,760,000 c) 4,435,236 d) 5,625,000 e) 6,084,000 f) none of the above.
The possible number of license plates is 6084000 .
We have to make a 6 word license plate in which first two are letters and remaining four are digits.
conditions are :
1. letters and digits can repeat themselves
2. 1st digit can't be 0.
taking into account these conditions
we know total letters are 26 and total digits are 10 ( 0,1,2,3,4,5,6,7,8,9)
Now if we divide number plate in 6 columns where first two are filler by letters and rest four by digits so
1st column can be filled in ways = 26
2nd column can be filled in ways = 26
3rd column can be filled in ways = 9 ( as zero is not allowed )
4th column can be filled in ways = 10
5th column can be filled in ways = 10
6th column can be filled in ways = 10
therefore, total number of ways = 26x26x9x10x10x10
= 6084000 ways
The possible number of license plates is 6084000 .

Given g(x)=-x-4g(x)=−x−4, solve for xx when g(x)=10g(x)=10.
The solution for x in the function when the function g(x) = 10 is 4
How to determine the solution for x in the function?From the question, we have the following equation that can be used in our computation:
g(x)=x-4
To make the equation legible, we need to rewrite it
So, we have the following representation
g(x) = x - 4
Also from the question, we have
g(x) = 10
This means that we calculate x when g(x) = 10
Substitute the known values in the above equation, so, we have the following representation
10 = x - 4
So, we have the following equation
x - 4 = 10
Add 4 to both sides of the equation
So, we have the following representation
x - 4 + 4 = 10 + 4
Evaluate the equation
x = 14
Hence, the solution is 14

Can anyone write the equation of this graph?
The equation of the graph in the figure is f(x) = |x - 3| + 5
How to find the equation of the graph line?Given that the graph is an absolute value graph
We start by calculating the vertex of the graph
In this case, the graph has it minimum point located at the coordinate (3, 5)
This coordinate can then be interpreted as
(h, k) = (3, 5)
As a general rule, the general representation of the equation of an absolute value function is f(x) = |x - h| + k
Substitute the known values in the above equation
So, we have the following equation
f(x) = |x - 3| + 5
Hence, the equation of the graph is f(x) = |x - 3| + 5

When two angles are supplementary to each other, it means that they add up to 180°.
Therefore:
∠A + ∠B = 180°
⇒ (4x + 30)° + (2x - 30)° = 180°
⇒ 4x + 30 + 2x - 30 = 180
⇒ 4x + 2x + 30 - 30 = 180 [Combining like terms]
