Answer:

Below are the responses to the given question:

Step-by-step explanation:

Let X become the random marble variable & g have been any function.

Now.

For point a:

When X is discreet, the g(X) expectation is defined as follows

Then there will be a change of position.

E[g(X)] = X x∈X g(x)f(x)

If f is X and X's mass likelihood function support X.

For point b:

When X is continuing the g(X) expectations is calculated as, E[g(X)] = Z ∞ −∞ g(x)f(x) dx, where f is the X transportation distances of probability.If E(X) = −∞ or E(X) = ∞ (i.e., E(|X|) = ∞), they say it has nothing to expect from EX is occasionally written to stress that a specific probability distribution X is expected.Its expectation is given in the form of,E[g(X)] = Z x −∞ g(x) dF(x). , sometimes for the continuous random vary (x). Here F(x) is X's distributed feature. The anticipation operator bears the lineage of comprehensive & integral features. The superposition principle shows in detail how expectation maintains equality and is a skill.

The linear equation that could be used to find her monthly pay rate will be y = 12x + 50.

It is referred to as the relationship between two variables, and a straight line is produced when the linear equation's graph is shown. The equation is referred to as a linear equation in one variable if just one variable is contained in the linear equation.

It is given that, Esther is employed by a marketing firm. She makes $12 per hour and receives a $50 monthly travel reimbursement.

Suppose x be the number of months,

The linear equation could be used to find her monthly pay rate is,

Total amount = Amount per hour×number of hour+ travel allowance

y = 12x + 50

Thus, the obtained linear equation for a given condition will be y = 12x + 50.

Answer:

part a answer is b and part b answer is 3

Step-by-step explanation:

This is is one value (and not two values separated by a comma) and it's slightly over 30 thousand.

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

Explanation:

There are n = 9 letters in the word "PEPPERONI"

If we could tell all the letters apart, there would be 9! = 9*8*7*6*5*4*3*2*1 = 362,880 permutations, and that would be the answer.

However, we have repeated letters that we cannot tell apart. The P shows up a = 3 times, and the E shows up b = 2 times. So we need to divide by a!*b! = 3!*2! = 6*2 = 12 to correct for the overcounting. That leads to the final answer of (362,880)/(12) = 30,240

Answer:

B. 745 miles

Step-by-step explanation:

Given that

Kim took 3000 miles trip in 4 days

And,

1st day - 850 miles

2nd day - 745 miles

3rd day - 660 miles

We need to find out that how much she travel in the 4th day

So, it is

= 3000 miles - 850 miles - 745 miles - 660 miles

= 745 miles

Hence, the option b is correct

Answer:

The answer is 77.27%

Step-by-step explanation:

Please mark brainliest!

Enjoy the rest of your day!

Answer:

77.2727.. (repeating)%

or 77 3/11 %

Although im not sure if fractions are accepted in percents, so stick to the first option

Step-by-step explanation:

A percent is simply [tex]\frac{}{100}[/tex]

How many 22's are there in 100? 100/22=4.54 repeating

So 22*4.54 repeating = 100

do the same to both sides of the equation

17 / 22

17*4.54 repeating

77.27272.../100

so 77.27272727... %

Answer:

The answer is D 763.

Step-by-step explanation:

Don't have an explanation

A chicken farmer needs to sell 763 crates to realize a profit of $11,300.

Equation

A statement of equivalence between two expressions containing variables and/or numbers is called an equation. In essence, equations are questions, and attempts to discover systematic answers to those questions have spurred the development of mathematics.

Equation according to the given information

Based on the given information describe the problem is equation.

(34.24 × x) - (7312 + 9.86x) = 11300

34.24x - 7312 - 9.86x = 11300

34.24x - 9.86x = 11300 + 7312

24.38x = 18612

x = 18612 / 24.38

x = 763

Hence chicken farmers need to sell 763 crate

Answer:

  B) 171 units^2

Step-by-step explanation:

The area is given by the formula ...

  A = 1/2(b1 +b2)h

Filling in the given base and height values, we find the area to be ...

  A = 1/2(23 +15)(9) = (19)(9) = 171 . . . square units

_____

Additional comment

You can select the correct answer choice simply on the basis of "reasonableness." If this were a 9×15 rectangle, its area would be 9×15 = 135 square units, more than 85.5. You know its area is less than a 9×23 rectangle, so is less than 9×23 = 207 square units. Only one answer choice is a value between 135 and 207.

Multiplication by 9 is not so hard. It is multiplication by 10-1:

Step-by-step explanation:

Answer:

V ≈ 706.9 cm³

Step-by-step explanation:

The volume (V) of a cylinder is calculated as

V = πr²h ( r is the radius and h the height )

Here r = 5 and h = 9 , then

V = π × 5² × 9

   = π × 25 × 9

   = 225π

   ≈ 706.9 cm³ ( to the nearest tenth )

Answer:

[tex]f(7) = 1[/tex]

Step-by-step explanation:

Given

[tex]f(x) = \left[\begin{array}{cc}2x+3&1 <x < 4\\1&x>4\end{array}[/tex]

Required

Determine f(7)

To do this, we make use of

[tex]f(x) = 1[/tex]

Because [tex]7 > 4[/tex]

So, we have:

[tex]f(7) = 1[/tex]

Answer:

7.211

Step-by-step explanation:

I'm going to assume that's supposed to say (33, 5) to (37, -1)

Use the pythagorean theorem: a^2 + b^2 = c^2

"a" is going to be your difference in x values (37 - 33) = 4

"b" is going to be your difference in y values (5 - (-1)) = 6

4^2 + 6^2 = c^2

16 + 36 = c^2

52 = c^2

sqrt(52) = c

7.211 = c

Answer:

a = 12 and b = 18

Step-by-step explanation:

Given that,

8,a,b,27 are in geometric sequence.

For a GP, the nth term is given by :

[tex]a_n=ar^{n-1}[/tex]

Put n = 4

[tex]a_4=ar^{4-1}\\\\a_4=ar^3\\\\27=8\times r^3\\\\r^3=\dfrac{27}{8}\\\\r=\dfrac{3}{2}=1.5[/tex]

Put n = 2,

[tex]a_2=ar^{2-1}\\\\a=ar\\\\a=8\times 1.5\\\\a=12[/tex]

Put n = 3

[tex]a_3=ar^2\\\\=8\times 1.5^2\\\\b =18[/tex]

So, the values of a and b is 12 and 18 respectively.
