Using the Fundamental Counting Theorem, it is found that there are 60 possible 3-course meals.

Given,

In the question:

A restaurant offers a choice of 4 salads, 5 main courses, and 3 desserts.

To find the how many possible 3-course meals are there?

Now, According to the question:

Let's know:

What is the Fundamental Counting Theorem?

It is a theorem that states that if there are n things, each with  ways to be done, each thing independent of the other, the number of ways they can be done is:

[tex]N=n_1[/tex] × [tex]n_2[/tex] × [tex]n_3[/tex]... ×[tex]n_n[/tex]

In this problem, considering the number of salads, main courses and desserts, we have that:

[tex]n_1=4 , n_2=5,n_3=3[/tex]

The total number of options is given by:

N = 4 × 5 × 3

N = 60

Hence, Using the Fundamental Counting Theorem, it is found that there are 60 possible 3-course meals.

The unknown angle of the right angle triangle is as follows:

A right angle triangle is a triangle that has one of its angles as 90 degrees.  The sides of a right angle triangle can be named base on the position of the angles. The sides includes hypotenuse side, opposite side and adjacent side.

The sum of angles in a right angle triangle is 180 degrees.  Therefore, let's find the ∠C in the triangle ABC.

Therefore,

180 = ∠A + ∠B + ∠C

m ∠B = y + 40

m ∠C = 3y - 10

m ∠A = 90°

Hence,

180 = 3y - 10 + y + 40 + 90

180 = 4y + 120

180 - 120 = 4y

y = 60 / 4

y = 15

Hence,

m ∠C = 3(15) - 10

m ∠C = 45 - 10

m ∠C = 35 degrees

Answer: x =4 , y =1

Step-by-step explanation:

Multiply the first equation by 4,and multiply the second equation by 3.

4(4x+3y=19)

3(3x−4y=8)

Becomes:

16x+12y=76

9x−12y=24

Add these equations to eliminate y:

25x=100

Then solve 25x=100 for x:

25x=100

(Divide both sides by 25)

x =4

Now that we've found x let's plug it back in to solve for y.

Write down an original equation:

4x+3y=19

Substitute4forxin4x+3y=19:

(4)(4)+3y=19

3y+16=19( Simplify both sides of the equation)

3y+16+−16 = 19+−16 (Add -16 to both sides)

3y=3

(Divide both sides by 3)

y=1

The equation of the line that passes through the point (5, 4) and is perpendicular to the line whose equation 2x + y = 3 is y = 1/2x + 3/2

The given equation of the line is

2x + y = 3

y = 3 - 2x

y = -2x + 3

The slope of the line is -2

The slope of the original line will be negative inverse of -2

= - 1/-2

= 1/2

The line is passing through the point (5, 4)

The slope intercept form is

y = mx + b

Substitute the values in the equation

4 = 1/2(5) + b

4 = 5/2 + b

b = 4 - (5/2)

b = 3/2

Therefore, the equation of the line is y = 1/2x + 3/2

Step-by-step explanation:

angle bisector theorem :

the ratio of the 2 baseline segments is the same as the ratio of the 2 legs of the main triangle.

in our case :

44.8/56 = (x + 4)/35

x + 4 = 44.8×35/56 = 44.8×5/8 = 28 mm

x = 24

FYI : one way of explaining the theorem is : we could see this as 2 projections originating from E at the same angle but onto a tilted projection screen.

the length on the projection screen (HD or GD) is directly related to the distance from the projection point to the end of the tilted projection : ED or EG. and so the ratios of both projections must be equal (due to the equal angle).

so, in our case

35/56 = (x + 4)/44.8

which leads, of course, to the same result

44.8×35/56 = x + 4

What is equation straight line?

Y = mx + c is the general equation for a straight line, where m denotes the line's slope and c the y-intercept. It is the version of the equation for a straight line that is used most frequently in geometry. There are numerous ways to express the equation of a straight line, including point-slope form, slope-intercept form, general form, standard form, etc. A straight line is a geometric object with two dimensions and infinite lengths at both ends. The formulas for the equation of a straight line that are most frequently employed are y = mx + c and axe + by = c. Other versions include point-slope, slope-intercept, standard, general, and others.

What can we learn from mean and standard deviation?

In statistics, the measurement of variability known as the standard deviation (SD) is frequently utilised. It demonstrates how different things are from the norm (mean). While a high SD shows that the data are dispersed throughout a wide range of values, a low SD suggests that the data points tend to be close to the mean.

Mean = 75.1

Standard Deviation = 9.1

Answer:

56

Step-by-step explanation:

When you subtract a negative number. Just consider it addition.

So, 40+16

It's very simple from there.

Answer:

56!

Step-by-step explanation:

The question is 40 minus negative 16.
When you subtract a negative, it's the same as adding.

So 40 - (-16) is the same as 40 + 16, which equals 56.

Example:

If you have 3 apples, and you remove negative 3 apples from 3, now you have 6.
So, 3 - (-3) = 6.

The consequence of the two functions f(x) = (1 / 6) · ∛x and g(x) = 6 · x³ by composition is f[g (x)] = (1 / 6) · ∛3 · x and g[f (x)] = (1 / 6) · x³, respectively.

In this question we must use the definition of composition between two functions f and g, where the independent variable of the function f is substituted by function g. That is to say:

f ° g (x) = f [g(x)]

If we know that f(x) = (1 / 6) · ∛x and g(x) = 6 · x³, then the result of each composition is:

f [g (x)] = (1 / 6) · ∛(6 · x³)

f[g (x)] = (1 / 6) · ∛3 · x

g[f (x)] = 6 · [(1 / 6) · ∛(6 · x³)]³

g[f (x)] = 6 · (1 / 216) · (6 · x³)

g[f (x)] = (1 / 6) · x³

The results of the compositions of the two functions f(x) = (1 / 6) · ∛x and g(x) = 6 · x³ are f[g (x)] = (1 / 6) · ∛3 · x and g[f (x)] = (1 / 6) · x³, respectively.

x = 2 , y' = 70 , x' = 30 : by using the property of SAS(side angle side) in ΔKMN and ΔKLI as they were similar polygon.

The property of a triangle whose two sides and the angle between these sides are stated is "SAS," which stands for "Side, Angle, Side". The SAS formula can be used to determine the area of a given triangle ABC with two known sides and an included angle between these sides.

Assume that the triangle's three sides are a, b, and c.

A SAS Triangle's perimeter

The following formula can be used to determine a triangle's area using SAS:

When sides "b" and "c" are known, along with angle A, the triangle's area is equal to: 1/2 bc sin(A)

The area of the triangle is equal to 1/2 ab sin(C) when sides 'b' and 'a' as well as included angle B are known

when sides "a" and "c" were added using SAS in triangle 1ΔMKN ~ ΔJKL

So, MN/KN = JL/KL

(x+1)/12 = (3x-2)/32

∴ 5x = 10 ⇒ x = 2

Using same property (SAS) in triangle 2

J = 80

∴ 30 = <x'

∵ in a triangle sum of angles is equal to 180° so, y' + <

J + 30 = 180

∴ <J = 80

then, y' = 70 and x' = 30

The annual rate of interest she is charging you is 12%.

Given that, you ask your best friend to lend you $200 to buy your favorite toy.

An interest rate tells you how high the cost of borrowing is, or high the rewards are for saving. So, if you're a borrower, the interest rate is the amount you are charged for borrowing money, shown as a percentage of the total amount of the loan.

Here,

Extra money per month =$2

Extra money per year = $2×12

Extra money per two year = 2×2×12 = 4×12 = $48

Money lend = $200

Money given after two years = $(200+48) = $248

Now, the rate of interest can be find using SI=(P×R×T)/100

48= (200×R×2)/100

⇒ 48= 4R

The probability that a student is chosen randomly from the class has a cat or a dog is 26/29.

It is based on the probabilities that something could happen. The theory of probability primarily relies on the justification for probability. A coin is tossed, for instance, and the theoretical likelihood of randomly receiving a head is 1 in 2.

explanation:

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

The total strength of the class is 29

The probability that a student is chosen randomly from the class has a cat or a dog =  Number of favorable outcomes / total number of outcomes

P(E) = 26/29
