3.) Find the domain and range for each of the following functions.

Answer:

8.550

Step-by-step explanation:

Answer:

The answer is: g ( x) and f ( x) are not inverses of each other.

Step-by-step explanation:

This is why you need to check both ways: sometimes there are fussy technical considerations, usually involving square roots, that force the composition not to work, because the domains and ranges of the two functions aren't compatible.

Answer:

(a) 2/3

(b) 45

Step-by-step explanation:

(a)

The "ratio of shirts to skirts" means "the number of shirts divided by number of skirts."

10 shirts

15 skirts

shirts : skirts = 10/15 = 2/3

Answer: 2/3

(b)

In the simplified ratio, there are 2 shirts for every 3 skirts.

Add 2 + 3 = 5.

The ratio of skirts to total number of items of clothing is 3:5.

There are 3 skirts to each 5 items of clothing.

Set up a proportion.

3/5 = x/75

5x = 3 * 75

x = 3 * 15

x = 45

Answer: 45

Answer: Choice A

m = undefined

point (-2,5)

==================================================

Explanation:

The equation x = -2 describes a vertical line in which every point on this line has x coordinate -2. Two points on this line are (-2,0) and (-2,1)

Another point on this line is (-2,5) since this also has x coordinate -2.

------------------

All vertical lines have undefined slope.

Let's pick two points such as (-2,0) and (-2,1) and find the slope through them

m = (y2-y1)/(x2-x1)

m = (1-0)/(-2-(-2))

m = (1-0)/(-2+2)

m = 1/0

m = undefined, since we cannot divide by zero.

Answer:

300

Step-by-step explanation:

24000/80

Answer:

300

Step-by-step explanation:

you have to sell $24000 worth of tickets and each is $80, so you do 24000/80 which you get 300 so you have to sell 300 more to meet its goal. since one ticket is 80 dollars then you divide 24000 with 80 so you get how many more tickets need to be sold. If you check your answer 300 tickets and each is $80 you do 300x80 which gives you $24000.

1.3027

Step-by-step explanation:

Answer: 253

Step-by-step explanation:

First, we have two numbers A and B.

We know that all numbers can be written as a product of prime numbers.

And the HCF of A and B is 23

Then we can write:

A = 23*a

B = 23*b

(remember that 23 is a prime number)

Where a and b are larger than 1.

Now we know that the least common multiple between them is 644.

Notice that the primes that conform a can not be the same as the ones for b, because in that case, the HCF would not be 23.

Now to find a and b we can compute:

644/23 = 28.

28 = a*b

Now let's write 28 as a product of prime numbers:

a*b = 28 = 4*7 = 2*2*7

Then we can define:

a = 2*2

b = 7.

Our two numbers are:

A = 23*2*2 = 92

B = 23*7 = 161

A + B = 92 + 161 = 253

The sum of the two numbers would be:

253

Assume the two numbers be [tex]x[/tex] and [tex]y[/tex]

Given that,

HCF of [tex]x[/tex] and [tex]y[/tex] = 23

so,

The numbers could be written as:

23[tex]x[/tex] and 23[tex]y[/tex]

We know that,

LCM of 23[tex]x[/tex] and 23[tex]y[/tex] = 644

We also know that,

LCM × HCF = The product of two numbers

∵ 644 × 23 = 23[tex]x[/tex] × 23[tex]y[/tex]

So, by solving them we get;

14812/529 = [tex]x[/tex] × [tex]y[/tex]

∵ [tex]x[/tex] × [tex]y[/tex] = 28

If we prime factorize 28, we get

28 = 2 × 2 × 7

This gives us,

[tex]x =[/tex]23 × 2 × 2 = 92

[tex]y =[/tex] 23 × 7 = 161

Thus, the sum of the two numbers = 92 + 161 = 253

Not perpendicular and not parallel.

Step-by-step explanation:

The equations are not perpendicular because the slopes of the two lines are not negative reciprocals.

The equations are not parallel because the slopes of the two lines are not equal.

[tex]-16x^2-9x+12[/tex]

Step-by-step explanation:

[tex]2x-3x+ 10x[/tex]

[tex]-16x^2-9x+12[/tex]

[tex]15x-6x^2+3[/tex]

[tex]-7x+ 9x^9 - 11x[/tex]

Standard form is when the polynomial's terms's degrees go down so the highest power is the first and the lowest is the last.

We see that the first expression can be more simplified so that isn't right.

We see that the second expression is in standard form so that might be right.

We see that the third expression has the highest power as the second term so that is wrong

We see that last expression is the same as the third one so that is also wrong.

We can conclude that [tex]-16x^2-9x+12[/tex] is the correct one or in standard form.

Answer:

They will make 1 triangle the lines will keep going until they meet

From the given triangle only one triangle can be made.

Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.

One of the first areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.

Given that the unformed triangle is given in the image.

The triangle can be made by extending the hypotenuse and the perpendicular line to intersect each other at the point. Only one triangle can be formed by doing so.

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data :

x: ____ 1____ 2____ 4____ 8____ 16

p(x): _0.05_ 0.15__ 0.25__0.30__ 0.25

E(X) : Σ[(X). P(X)]

Σ(1*0.05) + (2*0.15) + (4*0.25) + (8*0.30) + (16 * 0.25)

= 7.75

B)

E(x) = u = 7.75

Var(X) = E[(x - u)²*p(x)] = (1 - 7.75)^2 * 0.05 + (2 - 7.75)^2 * 0.15 + (4 - 7.75)^2 * 0.25 + (8 - 7.75)^2 * 0.30 + (16 - 7.75)^2 * 0.25 = 27.7875

C)

Standard deviation (s)

s = √Var(x)

s= √27.7875

s = 5.271

D)

VAR(X) = E(X²) - (E(X))²

E(X²) = Σx²*p(x)

E(X²) = Σ(1^2 * 0.05 + 2^2 * 0.15 + 4^2 * 0.25 + 8^2 * 0.30 + 16^2 * 0.25) = 87.85

V(X) = E(X^2) - (E(X))^2 = 87.85 - 7.75^2 = 27.7875

Multistage sampling divides large populations into stages to make the sampling process more practical.

Step-by-step explanation:

Let’s say you wanted to find out which subjects U.S. school children preferred. A population list a list of all U.S. school children would be nearimpossible to come by, so you cannot take a sample of the population.

An example of multistage samples is the Gallup poll.

In this, we have to drawn the sample that should arise from the population that used the smaller and smaller group at every stage. It is applied for collecting the data from the large, and the group of people in national surveys.

The Gallup poll used multistage sampling. Like it randomly select a particular no of area codes after this randomly sample a no of phone numbers from within each area code.
