Which graph represents the function f(x) = Ix| -4?

3*sqrt(7)

3 times the square root of 7

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

Explanation:

I'm assuming the V stands for square root. You can write sqrt(63).

\(\sqrt{63} = \sqrt{9*7}\\\\\sqrt{63} = \sqrt{9}*\sqrt{7}\\\\\sqrt{63} = 3\sqrt{7}\)

The idea is to factor 63 in such a way that one factor is the largest perfect square possible, that way we can pull the root apart to simplify as shown above. The rule I used for the second step is \(\sqrt{x*y} = \sqrt{x}*\sqrt{y}\)

The probability that the next two offspring will both be girls is 1/3.

To find P both children are girls

A: Event that both children are girls

A: {MM} and B: {MF, FM, MM} →→ P (A ∩∩ B) = {MM}

Probability that both are males, if we know one is a female =P(A/B)=P(A∩B)/P(B)

(P(A∩B)P(B))

Given S = {MM, MF, FM, FF}, we can see that: P (A) = 1414; P (B) = 3434; P (A ∩∩ B) = 1414

Therefore,

P(B/A)=P(A∩B)/P(A) = (1/4)/(3/4)=1/3.

Answer:

It would be D

because you need to multiple 3x3 to get 9 so the answer to your problem is D

Answer:

B

Step-by-step explanation:

So we are trying to find the number that is not between \(\frac{\sqrt{16}}{2}\) and 3π on the number line. To do this, lets try to find roughly (exactly if possible) that \(\frac{\sqrt{16}}{2}\) and 3π are. Lets start with \(\frac{\sqrt{16}}{2}\).

\(\frac{\sqrt{16}}{2}=\frac{4}{2}=2\)

So now, by looking at the number line, we can see that the values must be greater than 2. Now lets find 3π. Lets use 3.14 for π (3.14 is actually smaller than the actual value of π):

3(3.14) = 9.42

So we know that the value must be less than 9.42.

We can rewrite answer choice A as 2.08, with is more than 2 and less than 9.42. Therefore, it is between the two numbers on the number line.

While I do not know the exact value of √0.4, I know that it will be less than 1, making it less than 2. Therefore, it is not between the two numbers on the number line, and therefore is our answer.

Lets go through the other two answer choices though.

For C, while 9.37 is close to 9.42, it is still less than 9.42 and greater than 2, and therefore is between the two numbers on the number line.

For D, √9 can be rewritten as 3, which is between the two numbers on the number line.

Even if you did not know that answer choice B, √0.4, was less than 1, you still would have been able to find that B was the correct answer by the process of elimination.

I hope you find my answer helpful.

Answer:

true

Step-by-step explanation:

Answer:

The correct option is J.II, III, IV and V only.

Step-by-step explanation:

A rational number are those numbers that can shown in a p/q form or as the ratio of two numbers.

The numbers that cannot be shown as the ratio of two numbers are known as irrational.

Consider each number at a time:

\(\sqrt{49} =7\equiv 7:1\)

\(0.287=\frac{287}{1000}\)

\(\sqrt{\frac{9}{16}}=\frac{3}{4}\equiv 3:4\)

\(25\equiv 25:1\)

Thus, the numbers that are rational are II, III, IV and V.

The correct option is J.

well, since the y-intercept is at -5, or namely when the line hits the y-axis is at -5, that's when x = 0, so the point is really (0 , -5), and we also know another point on the line, that is (-1 ,6), to get the equation of any straight line, we simply need two points off of it, so let's use those two

\(\stackrel{y-intercept}{(\stackrel{x_1}{0}~,~\stackrel{y_1}{-5})}\qquad (\stackrel{x_2}{-1}~,~\stackrel{y_2}{6}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{6}-\stackrel{y1}{(-5)}}}{\underset{run} {\underset{x_2}{-1}-\underset{x_1}{0}}} \implies \cfrac{6 +5}{-1} \implies \cfrac{ 11 }{ -1 } \implies - 11\)

\(\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-5)}=\stackrel{m}{- 11}(x-\stackrel{x_1}{0}) \implies y +5 = - 11 ( x -0) \\\\\\ y+5=-11x\implies {\Large \begin{array}{llll} y=-11x-5 \end{array}}\)

Answer: B: 140.4

Step-by-step explanation:

The expected value of buying one ticket in this charity raffle is $0.42. This means that, on average, a person can expect to win approximately $0.42 if they purchase a single ticket.

To calculate the expected value, we need to consider the probability of winning each prize multiplied by the value of the prize. Let's break it down:

- There is a 1/5000 chance of winning the $600 prize, so the expected value contribution from this prize is (1/5000) * $600 = $0.12.

- There are 3/5000 chances of winning the $300 prize, so the expected value contribution from these prizes is (3/5000) * $300 = $0.18.

- There are 5/5000 chances of winning the $40 prize, so the expected value contribution from these prizes is (5/5000) * $40 = $0.04.

- Finally, there are 20/5000 chances of winning the $5 prize, so the expected value contribution from these prizes is (20/5000) * $5 = $0.08.

Summing up all the expected value contributions, we get $0.12 + $0.18 + $0.04 + $0.08 = $0.42.

Therefore, if you buy one ticket in this raffle, the expected value of your winnings is $0.42.

Answer:

Step-by-step explanation:

1. Undo the operations done to n, in reverse order. Here, n has r added and the sum is multiplied by m. First we divide by m, then we subtract r.

  m(n+r) = s . . . given

  n +r = s/m . . . divide by m

  n = (s/m) -r . . . subtract r

__

2. Eliminate the parentheses, then proceed as above. Subtract the added term, then divide by the coefficient of n.

  m(n+r) = s

  mn +mr = s . . . eliminate parentheses

  mn = s -mr . . . subtract the added term

  n = (s -mr)/m . . . divide by the coefficient of n

It will take the town 21 years 4 months to reach 4600 in population

a rate is a ratio that compares two different quantities which have different units. For example, if we say John types 50 words in a minute, then his rate of typing is 50 words per minute. The word "per" gives a clue that we are dealing with a rate.

initial population = 3000

population increase every year = 2.5% of 3000

which is 2.5/100 x 3000 = 75

let the time taken to reach 4600 be d

increment for d number of years = 75d

Total population after d years is 75d + 3000

so 75d + 3000 = 4600

75d = 4600  - 3000

75d = 1600

d = 1600/75

d = 21.33 years which is 21 years 4 months

In conclusion 21 years 4 months is the time taken for the ton tto get tto 4600

The 3rd term of the geometric sequence is 6.

In mathematics, an equation is a statement that two expressions are equal. It usually contains one or more variables, which are unknown quantities that can take on different values. Equations are used to represent relationships between quantities, and they can be used to solve problems by finding the values of the variables that make the equation true.

An equation typically consists of two sides, separated by an equal sign. Each side can contain numbers, variables, and mathematical operations such as addition, subtraction, multiplication, division, exponents, and roots. For example, the equation:

2x + 3 = 7

contains the variable x, as well as constants 2, 3, and 7, and mathematical operations of addition and multiplication.

Equations can be solved by applying algebraic techniques to isolate the variable on one side of the equation. For example, to solve the above equation for x, we can first subtract 3 from both sides to get:

2x = 4

Then, we can divide both sides by 2 to get

x = 2

This is the solution to the equation, which means that x must be equal to 2 in order to make the equation true.

Equations are used in many areas of mathematics, including algebra, calculus, geometry, and trigonometry. They are also used in physics, engineering, and other sciences to model physical phenomena and solve problems related to them.

Let's call the first term of the geometric sequence "a" and the common ratio "r".

The formula for the nth term of a geometric sequence is:

an = a *\(r^(n-1)\)

We are given that the 2nd term is 2, so we know that:

a * r = 2 --(1)

We are also given that the 5th term is 432, so we know that:

a * \(r^4\) = 432 --(2)

Now we need to solve for "a" and "r" in order to find the 3rd term.

First, let's solve equation (1) for "a":

a = 2 / r

Now we can substitute this expression for "a" into equation (2):

(2/r) *\(r^4\)= 432

Simplifying, we get:

\(r^3\)= 54

Taking the cube root of both sides, we get:

r = 3

Now we can substitute this value for "r" back into equation (1) to solve for "a":

a * 3 = 2

a = 2/3

So the first term of the sequence is 2/3 and the common ratio is 3.

Now we can use the formula for the 3rd term of a geometric sequence:

a3 = a * \(r^(3-1)\)

a3 = (2/3) *\(3^2\)

a3 = (2/3) * 9

a3 = 6

Therefore, the 3rd term of the geometric sequence is 6.
