What is the range of the function f(x) = 3/4|x|- 3

Answer:

en total 6 horas

espero ayudar amiga ;)

Answer:

It's 6 hours cuz 3*2 is 6 so thats twice as much. It will travel 800 kilometers in 6 hours.

Step-by-step explanation:

So, there are 34 second-hand vehicles in total.

Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 indicates that the event is impossible, and 1 indicates that the event is certain to occur. For example, if the probability of rolling a 6 on a fair die is 1/6, it means that in the long run, out of every six rolls, one of them is expected to be a 6.

Here,

a) Here is the completed frequency tree:

        |------- New (N)

        |

Vans ----|------- Second-hand (18)

        |

        |------- Total (50)

        |------- New (3)

        |

Mopeds --|------- Second-hand (24)

        |

        |------- Total (32)

To fill in the missing value N, we can start by filling in the total number of vans:

        |------- New (3)

        |

Vans ----|------- Second-hand (N - 3)

        |

        |------- Total (50)

We know that there are 3 new vans and a total of 50 vehicles, so there must be 47 second-hand vehicles (50 - 3 = 47). Therefore, we can fill in N:

        |------- New (3)

        |

Vans ----|------- Second-hand (44)

        |

        |------- Total (50)

b) To find out how many vehicles are second-hand, we add up the number of second-hand vans and the number of second-hand mopeds:

18 (second-hand vans) + 16 (second-hand mopeds) = 34

The value of A that makes the equation true for all values of x is A = \(2x^2\). Answer (E).

To begin, consider the following equation:

\(2^(x/12) = A/12x^2\)

We must determine the value of A that makes this equation true for all x values.

To begin, we can take the natural logarithm of both sides of the equation:

\(2(x/12) = 2(A/12x2)\)

We can simplify the left side of the equation by using the logarithm property that states log(ab) = b*log(a):

(x/12)

\(ln(2) = 2ln(x) - ln(A) (12)\)

Then, on one side of the equation, we can isolate ln(A):

ln(A) = (x/12)

\(2ln(x) + ln(2) + ln (12)\)

With base e, we can now exponentiate both sides of the equation:

A is equal to \(e((x/12)ln(2) + 2ln(x) + ln(12)).\)

To simplify even further, we can use exponent properties to combine the terms with ln:

\(A = 2^(x/12) * (x^2) * 12\)

Simplifying:

\(A = 2x^2\)

Therefore, the value of A that makes the equation true for all values of x is \(A = 2x^2\). Answer (E).

The variables of the equation are presented as follows:

The margin of error is calculated as follows:

\(M = t\frac{s}{\sqrt{n}}\)

As n is in the denominator, the margin of error is inverse proportional to the sample size, hence decreasing the sample size from 15 to 6 would result in a larger margin of error.

Step-by-step explanation:

At the rate of 12 balloons in 1/4 hour, you want to know how long it will take Lauren to fill 72 balloons.

The number 72 balloons is 6 times 12 balloons. We are told Lauren can keep up the same rate of filling, so we expect filling 72 balloons will take 6 times the 1/4 hour it takes for 12 balloons.

  6 · (1/4 hour) = 6/4 hours = 3/2 hours = 1 1/2 hours

It will take Lauren 1 1/2 hours to fill 72 balloons.

As a decimal, that's 1.5 hours.

If you need an equation, you could write ...

  t/72 = (1/4)/12 . . . . . time/balloons is a constant

Multiplying by 72 gives ...

The correct correlation between the heights of husbands and wives in the U.S. is around -0.3. The correlation between the heights of husbands and wives in the U.S. is not as strong as some might assume. It is about -0.3.

This is not a strong negative correlation, but it is still a negative one, indicating that as the height of one partner increases, the height of the other partner decreases. This relationship may be seen in married partners of all ages. It's important to note that the correlation may not be consistent among various populations, and it may vary in different places. The correlation between husbands and wives' heights is -0.3, which is a weak negative correlation.

It indicates that as the height of one partner increases, the height of the other partner decreases. When there is a weak negative correlation, the two variables are inversely related. That is, when one variable increases, the other variable decreases, albeit only slightly. The correlation is not consistent across all populations, and it may differ depending on where you are. Nonetheless, when compared to other correlations, such as a correlation of -0.9 or 0.9, the correlation between husbands and wives' heights is a weak negative one.

There are 7920 ways to seat 14 people in a circle such that every man is diametrically opposite a woman.

In this problem, we want to find the number of ways to seat 14 people in a circle such that every man is diametrically opposite a woman.

Since every man must be diametrically opposite a woman, we can pair each man with one woman. There are 5 men and 9 women, so there are 5 pairs. We need to find the number of ways to seat these 5 pairs of people in a circle.

To do this, we can first seat one pair in any position. Then, we can seat the second pair anywhere but opposite the first pair. This gives us 11 positions for the second pair. Continuing in this way, we see that there are 11 * 6 * 5 * 4 * 3 = 7920 ways to seat the 5 pairs of people in a circle.

So, there are 7920 ways to seat 14 people in a circle such that every man is diametrically opposite a woman.

Using Pythagoras Theorem, The height of the screen is approximately 27.18 inches.

Pythagoras Theorem is the way in which you can find the missing length of a right angled triangle.

We can use the Pythagorean theorem to solve this problem. Let's call the height of the screen "h". Then, according to the Pythagorean theorem, we have:

\(h^2 + 32^2 = 42^2\)

Simplifying this equation, we get:

\(h^2 + 1024 = 1764\)

Subtracting 1024 from both sides, we get:

\(h^2 = 740\)

Taking the square root of both sides, we get:

\(h = \sqrt{(740)}\)

Using a calculator to approximate the square root, we get:

h ≈ 27.18 inches

Hence, the height of the screen is approximately 27.18 inches.

To determine the exact concentration of the solution made, one can divide the mass of the solute with the volume of the solution.

A solution is the substance formed by the mixture of solute in solvent. The solute may or may not be dissolved in the solution. One can determine the exact concentration of the solution if the mass of solute added in the specific volume of solution is known. If the solution is made by someone else, then its concentration can be determined by process of titration.

The concentration of a solution is expressed in the form of moles or grams per unit liter. If the solution is unknown and only its dissolved chemical is known, then titration will help in determining the closest value of concentration if performed without human error. In titration, the use of glassware that that is more precise than the flasks, beakers, and graduated cylinders are used.

Answer:

Step-by-step explanation:

The area of the shaded region that is the segment of the circle is equal to 4.6 ft² to the nearest tenth.

To calculate the area of a segment of a circle, you need to know the radius of the circle, the central angle of the segment (in radians or degrees), and possibly the height of the segment (the distance from the chord of the segment to the center of the circle).

The formula for the area of a segment of a circle is:

A = θ/360° × πr² - 1/2 × r² × sinθ

where A is the area of the segment, r is the radius of the circle, and θ is the central angle of the segment in degrees.

From the question;

the central angle = 90°

radius r = 4ft

Area of the segment = 90°/360° × π4² - 1/2 × 4² × sin90°

Area of the segment = 1/4 × π × 4 × 4 - 1/2 × 4 × 4 × 1 {sin90° = 1}

Area of the segment = 4π × 8

Area of the segment = 4.5714

Answer:

y=3 x=4

Step-by-step explanation:

4x - 2y = 10

4x + y = 19

    -3y=-9

the 4x canceled out.

y=3

plug in y into one of the equations

4x + 3 = 19

4x=16

x=4

Hope this helps!

If not, I am sorry.

Answer:

(4, 3 )

Step-by-step explanation:

4x - 2y = 10 → (1)

4x + y = 19 → (2)

subtract (1) from (2) term by term

(4x - 4x) +y - (- 2y) = 19 - 10

0 + y + 2y = 9

3y = 9 ( divide both sides by 3 )

y = 3

substitute y = 3 into either of the 2 equations and solve for x

substituting into (2)

4x + 3 = 19 ( subtract 3 from both sides )

4x = 16 ( divide both sides by 4 )

x = 4

solution is (4, 3 )

a) Mean: 24, Standard Deviation: 3.89. b) Probability of more than 22 adults watching at work: 0.6965. c) Probability of exactly 19 adults watching at work: 0.0985. d) Probability of 12-16 adults watching: 0.1009.

a. The mean is 60 * 0.40 = 24. The standard deviation is sqrt(60 * 0.40 * 0.60) = 3.89.

b. Using the normal approximation, we can calculate the z-score for 22 as (22 - 24) / 3.89 = -0.51. From the standard normal distribution table, the probability of a z-score greater than -0.51 is 0.6965.

c. Using the normal approximation, we can calculate the z-score for 19 as (19 - 24) / 3.89 = -1.29. From the standard normal distribution table, the probability of a z-score of -1.29 is 0.0985.

d. To calculate the probability of 12, 13, 14, 15, or 16 adults watching the tournament at work, we need to calculate the individual probabilities for each value and sum them up. Using the normal approximation, we can calculate the z-scores for each value and find the corresponding probabilities. The sum of these probabilities is the final result.

Using the same approach as before, the z-scores for 12, 13, 14, 15, and 16 are -3.09, -2.71, -2.32, -1.94, and -1.55, respectively. The corresponding probabilities from the standard normal distribution table are 0.0010, 0.0034, 0.0107, 0.0274, and 0.0584. The sum of these probabilities is 0.1009.
