LLNNN, we contain 676000 combinations available for license plates.
How to estimate the number of possible license plates?The number on license plates exists in the form LLNNN, where L denotes a letter and N denotes a number.
As L can be anything from A to Z, there exist 26 combinations for that and as repetition stands allowed, for second and third letters, we also contain 26 combinations available, and therefore 26 × 26 = 676 combinations for letters.
But numbers exist from 0 to 9 i.e. 10 combinations for each place and a total of 10 × 10 × 10 = 1000 combinations.
Therefore, LLNNN, we contain 676000 combinations available for license plates.

solve the system:
2x+6y=36
x+4y=20
Let's solve this problem step-by-step
Let's set:
2x + 6y = 36 -- equation 1
x + 4y = 20 -- equation 2
(equation 2) * 2
2x + 8y = 40 -- equation 3
(equation 3) - (equation 1)
2y = 4
y = 2 -- equation 4
Plug (equation 4)'s value of y into (equation 2)
x + 4(2) = 20
x = 20 - 8
x = 12
Thus x = 12 and y = 2
Let's check, by substituting these values
[tex]2x + 6y = 36\\2(12)+6(2) = 36\\24+12=36\\36=36\\\\x+4y=20\\12+4(2)=20\\12+8=20\\20=20[/tex]
Answer: x = 12 and y = 2

Based on the calculations, the number of Jamal's triangle that are obtuse are: C. 3.
How to determine an obtuse triangle?In order to determine an obtuse triangle, we would apply Pythagorean theorem:
c² = a² + b²
Where:
c is the hypotenuse.a is the adjacent side.b is the opposite side.For an obtuse triangle, the square of the hypotenuse is greater than the sum of the square of both the adjacent and opposite side:
c² > a² + b²
For Triangle 1, we have:
7² > 6² + 3²
49 > 36 + 9
49 > 45 (obtuse triangle).
For Triangle 2, we have:
8² > 6² + 3²
64 > 36 + 9
64 > 45 (obtuse triangle).
For Triangle 3, we have:
8² > 7² + 3²
64 > 49 + 9
64 > 58 (obtuse triangle).
For Triangle 4, we have:
8² > 6² + 7²
64 > 36 + 49

PLS HELPPP WHAT IS THE ANSWER????
Answer:
212
Step-by-step explanation:
starting with (xy)
you first plug in x=2 and y=3
(2×3) = 6
then we add in the exponent of 3
6^3 = 216
this is because an exponent shows you how many times the number is multiple by itself (6×6×6)
next we work on x^4 by plugging in x=2
2^4=16
2×2×2×2
we do the same for x^2
2^2=4
2×2
next we do the division
16/4=4
finally we take the 216 and 4 and do the subtraction
216-4=212

Answer:
The median of the lower half of the data was determined to be 67 while the median of the upper half of the data was determined to be 92.
Step-by-step explanation:
Step 1: Order from least to greatest
51, 56, 62, 72, 79, 81, 82, 85, 89, 95, 97, 98
Step 2: Determine the median of the lower half of the data
There are 12 numbers which means that there is going to be 6 numbers on both sides of the data. So using the first 6 numbers we will be able to determine the median of the lower half of the data.
51, 56, 62, 72, 79, 81
Since there is an even amount of numbers, that means that we will need to find the middle between the 3rd and 4th number. We can do that by adding them up together and dividing by 2.
(62 + 72) / 2 = 67
Step 3: Determine the median of the upper half of the data
So using the first 6 numbers we will be able to determine the median of the upper half of the data.
82, 85, 89, 95, 97, 98
Since there is an even amount of numbers, that means that we will need to find the middle between the 3rd and 4th number. We can do that by adding them up together and dividing by 2.
(89 + 95) / 2 = 92
Answer: The median of the lower half of the data was determined to be 67 while the median of the upper half of the data was determined to be 92.

which graph shows the solution set for -5/2x-3<_2?
solving the equation given to us first:
-5x/2 = 5/1 ( ignore the ≤ symbol for now and replace with =) and cross multiply
you will get
-5x = 10
x = -10/5 ( minus doesn't stay in denominator so so we take up to numerator )
x = -2
so x ≤ -2
NOTE: if we have ≤ we shade the dot but if we have just < or we don't shade the dot.
soooo
x ≤ -2 will be going backwards
so the answer is option (C).
Hope this helps.

The equation of the directrix to the right of the center is equal to 2.8.
Given the following data:
(x - 1)²/9 - (y - 2)²/16 = 1.
How to determine the equation of the directrix?Mathematically, the standard equation of the directrix lines for a hyperbola of the form (x - h)²/a² - (y - k)²/b² = 1 is given by:
x = h ± a²/√(a² + b²)
Where:
a² = 9.b² = 16.h = 1.Substituting the given parameters into the standard equation, we have;
x = 1 ± a²/√(a² + b²)
x = 1 ± 9/√(9 + 16)
x = 1 ± 9/√25
x = 1 ± 9/5
x = 1 + 9/5
x = 1 + 1.8

What is conditional relative frequency?Conditional relative frequency is relative frequency conditional to some special characteristic.
For this case, we're specified the following table:
[tex]\begin{array}{cccc}&\text{Math}&\text{Other favorite subject}&\rm Total\\\text{Male}&0.35&0.65&1.0\\\text{Female}&0.45&0.55&1.0\\\rm Total &0.41&0.59&1.0 \end{array}[/tex]
It is given that:
the survey was given to 120 male students andthe survey was given to 180 female studentsWe have to find how many students in the survey said that math was their favorite subject.
From males, 0.35 out of 1 male said math was their favorite subject. (since total in male is 1, showing that the row of males got conditional relative frequency conditional to the gender male, and relative to the total count of males).
Thus, as out of 1, there was 0.35 supporter of math (from males), so from 120 male students, there were [tex]120\times 0.35 = 42[/tex] male students who had chosen math as their favorite subject.
Similarly, 0.45 per 1 female student chose their favorite subject as math.
Since there are 180 female students, therefore, total [tex]180\times 0.45 = 81[/tex] female students had chosen math as their favorite subject.
So, total 42+81=123 students had chosen math as their favorite subject.

Please help me pretty please
Answer: D.
Step-by-step explanation:
The equation [tex]f(x) = (x-1)^{2} - 2[/tex] works only for option D. If x is 2, for example, the equation would look like this: [tex]f(2) = (2-1)^{2} - 2[/tex]. This equals [tex](1)^{2} - 2[/tex] which equals negative one. Therefore, when x is 2, y is -1. All of the graphs have the point (2, -1). We can still tell though that it is not A or B because there are spaces in between the points. If x = 2.2, the equation would not work for A or B because there is not a point with an x value of 2.2. This is different for both C and D. Δ
Answer C ends off early. There are endpoints to the figure. If x = 4, the equation would not work. This is because there is no point in answer C that has an x value of 4. On the other hand, question D does have a point with an x value of 4.
If x = 4, the equation looks like [tex]f(4) = (4-1)^{2} - 2[/tex].
We can simplify this to [tex]f(4) = (3)^{2} - 2[/tex]
and then [tex]f(4) = 7[/tex]
This means that when x is 4, y is 7. This is true for no graph but option D. Therefore the answer to this problem is D.

Answer:
A function is increasing when the gradient is positive
A function is decreasing when the gradient is negative
Question 7
If you draw a tangent to the curve in the interval x < -2 then the tangent will have a positive gradient, and so the function is increasing in this interval.
If you draw a tangent to the curve in the interval x > -2 then the tangent will have a negative gradient, and so the function is decreasing in this interval.
If you draw a tangent to the curve at the vertex of the parabola, it will be a horizontal line, and so the gradient at x = -2 will be zero.
The function is increasing when x < -2
[tex](- \infty,-2)[/tex]
The function is decreasing when x > -2
[tex](-2, \infty)[/tex]
Additional information
We can actually determine the intervals where the function is increasing and decreasing by differentiating the function.
The equation of this graph is:
[tex]f(x)=-2x^2-8x-8[/tex]
[tex]\implies f'(x)=-4x-8[/tex]
The function is increasing when [tex]f'(x) > 0[/tex]
[tex]\implies -4x-8 > 0[/tex]
[tex]\implies -4x > 8[/tex]
[tex]\implies x < -2[/tex]
The function is decreasing when [tex]f'(x) < 0[/tex]
[tex]\implies -4x-8 < 0[/tex]
[tex]\implies -4x < 8[/tex]
[tex]\implies x > -2[/tex]
This concurs with the observations made from the graph.
Question 8
This is a straight line graph. The gradient is negative, so:
The function is decreasing for all real values of x
[tex](- \infty,+ \infty)[/tex]
But if they want the interval for the grid only, it would be -4 ≤ x ≤ 1
[tex][-4,1][/tex]
Question 9
If you draw a tangent to the curve in the interval x < -1 then the tangent will have a negative gradient, and so the function is decreasing in this interval.
If you draw a tangent to the curve in the interval x > -1 then the tangent will have a positive gradient, and so the function is increasing in this interval.
If you draw a tangent to the curve at the vertex of the parabola, it will be a horizontal line, and so the gradient at x = -1 will be zero.
The function is decreasing when x < -1
[tex](- \infty,-1)[/tex]
The function is increasing when x > -1

In △ABC, ∠B is a right angle, AB=30, and sec A=5/3. Find the value csc C in fraction and in decimal form.
Answer:
csc C = 5/3 = 1. (6)
Step-by-step explanation:
Given:
∠B = 90° is a right angle
AB = 30
We know that:
sec A = 5/3 = 1/ cos A = 1/ ( adjacent side/hypothenuse) =
hypothenuse/ adjacent side to angle A
csc C = 1/ sin C = 1/ sinC = 1/ (opposite side /hypothenuse) =
hypothenuse/ opposite side to angle C
Note that :
adjacent side to angle A is the same as opposite side to angle C
Therefore sec A = csc C = 5/3 ( fraction form) = 1.(6) (decimal form)
