Margo was helping clean up after a class party. There were 3 boxes remaining with pizza in them. Each box had 3 of a pizza left. How much pizza was left in all?

Answer:

To find the product of 1/4 and 1/6, we need to first find a common denominator. In this case, we can use the least common multiple of 4 and 6, which is 12. We can then rewrite 1/4 and 1/6 as 6/12 and 2/12, respectively. The product of these two fractions is then 6/12 * 2/12 = (6 * 2)/(12 * 12) = 1/12. Therefore, 1/4 x 1/6 = 1/12.

Alternatively, we can simply cancel out common factors in the numerator and denominator of the two fractions before multiplying them. In this case, we can cancel out the common factor of 1 in the numerator and the common factor of 4 in the denominator to get 1/4 * 1/6 = 1/(4 * 6) = 1/24.

Both methods give us the same answer, so we can use either one to solve this problem.

The rate of flow outward through the hemisphere x² + y² + z² = 9, z >= 0 is zero.

Given that,

Seawater has a density of 1025 kg/m³ and moves at a constant velocity field defined by the equations v = yi + xj, where x, y, and z are measured in meters and the components of V are expressed in meters per second.

We have to find the rate of flow outward through the hemisphere x² + y² + z² = 9, z >= 0.

We know that,

v= yi + xj, and density = 1025 kg/m³

F=1025(yi + xj)

After solving the R(u,v) we get zero.

Therefore, the rate of flow outward through the hemisphere x² + y² + z² = 9, z >= 0 is zero.

The equation of a line passing through (x1, y1) is y - y1 = m(x - x1).

The equation of a line:

The equation of a line means an equation in x and y whose solution set is a line in the (x,y) plane. The most popular form in algebra is the "slope-intercept" form. y = mx + b. This in effect uses x as a parameter and writes y as a function of x: y = f(x) = mx+b.

Here we have to find the equation of a line passing through (x1, y1) and the slope.

Data given:

Point on the line = (x1, y1)

Slope = m

By this we get the equation of a line as:

y - y1 = m(x - x1)

Therefore the equation of a line is y - y1 = m(x-x1).

Therefore , the test statistic comes out to be t = 8.645.

A test statistic is a statistic used in statistical hypothesis testing .A hypothesis test is typically expressed as a test statistic, which can be thought of as a numerical summary of a data set that condenses the data into a single value that can be used to perform the hypothesis test.

Here,

Parameter = u1 - u2

where

[tex]{X^{'}_{1}[/tex] = 3.27

[tex]{X^{'}_{2}[/tex] = 2.95

So using formula

=> t = [tex]\frac{X^{'}_{1} - X^{'}_{2} }{Sp\sqrt{\frac{1}{n1} +\frac{1}{n2} } }[/tex]

=> t = [tex]\frac{3.27 - 2.95 }{0.23\sqrt{\frac{1}{100} +\frac{1}{100} } }[/tex]

=> t = 9.838

and

=> t = [tex]\frac{3.27 - 2.95 }{0.29\sqrt{\frac{1}{100} +\frac{1}{100} } }[/tex]

The probability that a randomly chosen plate contains the number 2222 is 0.000028 approximately.

The probability that a randomly chosen plate contains the sub-string HI is 0.002548  approximately.

Given that:

The license plate was in the form of 3 letters followed by 3 digits or 2 letters followed by 4 digits.

Part (A)

Let A be the way the symbol is three letters followed by three numbers, and B be the way two letters followed by four numbers.

Repetition is allowed here. There are 26 alphabetic characters and 10 unique digits.

If 3 letters followed by 3 numbers, the selection method is:

   26 × 26 × 26 × 10 × 10 × 10

⇒ (26)² ×(10)⁴ = 6760000

The number of possibilities is 17576000 + 6760000 = 24336000

contains the digits 2222.

That is, the first two letters can be any alphabet, but the remaining digits he must be 2222. Disk contains number 2222:

   (26) ² = 676

Probability that randomly selected disk contains number 2222:

676/24336000 ≈ 0.000028

Part (B):

Selected disk contains substring HI Number of possibilities:

3 letters followed by 3 digits, the disc has Un

26 × 1 ×10³ × 1 × 26 ×10³

2 letters followed by 4 digits, the number of possible ways is as follows.

1 × 10⁴

n 1 =100, ^p 1 =.1,n 2 =100, ^p 2 =.13.

(a) Set up the appropriate null and alternative hypotheses.

(b) Compute the value of the test statistic.

(c) Draw a conclusion as to whether there is a difference between the two assembly lines

the answer is 4

Step-by-step explanation:

As the time increases, the angular velocity i.e. omega also increases quadratically with time.

Given,

From the figure,

Radius of wheel = 0.2 m

Acceleration, a = 4t m/s^2

then the angular acceleration of wheel can be determined by formula,

[tex]a=\alpha * r[/tex]

Where, r=radius of wheel =0.2 m

[tex]4t=\alpha * 0.2\\20t=\alpha[/tex]

We know that the angular acceleration is the change in angular velocity over time.

[tex]\alpha=\frac{d\omega}{dt}\\\\20t=\frac{d\omega}{dt}\\\\d\omega=20tdt\\\\\omega=\int\limits^t_0 {20t} \, dt \\\\\omega=\frac{20t^2}{2}-0\\\\\omega=10t^2[/tex]

From the above equation it is clear that omega i.e. angular velocity is dependent of time

omega is directly proportional to square of time

For

t=1 then ω=10

t=2 then ω=10(4)=40

t=3 then ω=10(9)=90.....and so on.

It means as time increases, then angular velocity also increases quadratically with time.

The length of the longer and shorter pieces of hose is equal to 19ft and 8ft respectively.

As given in the question,

length of the hose = 27ft

Let 'x' be the length of the longer piece

and 'y' be the length of shorter piece

As per given condition:

System of equations are:

x = 2y + 3  __(1)

x + y = 27 __(2)

Substitute the value x from (1) in (2) we get,

2y + 3 + y = 27

⇒3y + 3 = 27

⇒ 3y = 27 - 3

⇒3y = 24

⇒y = 24/3

⇒y = 8ft.

Now,

x = 2(8) + 3

⇒ x = 19ft

Therefore, the length of the longer and shorter piece cut from a 27ft long hose is equal to 19ft and 8ft respectively.

The features of the function are given as follows:

The horizontal asymptote is the limit of f(x) as x goes to infinity. To obtain this limit, we consider only the terms with the highest exponent of the numerator and of the denominator, hence:

g(x) = -5x/x -> y = 5 is the horizontal asymptote.

The vertical asymptote is the value of x for which the function is not defined, hence it is the zero of the denominator, thus:

x - 2 = 0 -> x = 2.

The x-intercept is the point (x,0), in which x is found when y = 0, hence:

-5x + 10 = 0

-5x = -10

5x = 10

x = 2.

However, the function is not defined at x = 2, meaning that it has no x-intercept.

The y-intercept is the value of y when x = 0, hence:

y = 10/-2 = -5.

The coordinates are (0,-5).

The entire function can be simplified as follows:

(-5x + 10)/(x - 2) = [-5(x - 2)]/(x - 2) = -5.

Meaning that the function has no holes.

The equation of the line passing through (3,4) and having slope m = 3/2 is y = 3/2x + 4.

Given points : (3,4)

The equation of a line with slope 3/2 and passing through point (3,4) is y = 3/2x + 4. This equation can be used to calculate the y-coordinate of any point on the line, given its x-coordinate. For example, if the x-coordinate of a point is 6, then its corresponding y-coordinate is 11. In general, for any x-coordinate, the corresponding y-coordinate is given by 3/2 times the x-coordinate plus 4.

Given slope : m = 3/2

We know that the equation of a line with slope m and passing through point (x1, y1)is given by :

y - y1 = m(x - x1)

The probability of an event is the ratio of the number of possible outcome to the number of required outcome.

Therefore: The probability of rolling a three is the ratio of the frequency of an outcome of threes to the sum of the frequency of all the events.

The correct option from which the best details of finding an experimental  probability can be obtained is the option that states that the experimental probability of rolling a three is the ratio of the count of the number of times three occurs to the total number of trials, which is the frequency of rolling a three to the sum of all the frequencies in the experiment.

Mathematically, we get;

The probability of an event E, P(E) = [tex]\frac{Number\, of \, outcomes \, three}{Total \, number \, of \, outcomes}[/tex]

Therefore

[tex]P(3) = \dfrac{Number\, of \, times \, three\, occurs }{Total\, number \, of \, trials} = \dfrac{Freqiuency\ of \ 3s }{Sum\ of \ ther \ frequencies}[/tex]

The law of sines tells you the ratios of side length to the sine of the opposite angle are the same for all side/angle pairs in the triangle.
