Answer:

The first step on how to solve the ratio is to write the values you want to compare and you can write such values in any given form like using colon or through division sign or by writing isto. Let’s understand the steps through an example. Suppose you want to take out the ratio of your maths and physics marks. You have got 90 marks in maths and 70 marks in physics. So firstly I will write it in the form of a ratio.  

90 is to 70 or 90:70 or 90/70.

Second step on how to solve the problem is to reduce the values into their simplest way. So for that you can take out the common factors from the numbers. And then we can divide both of the numbers from such a common factor so that we can get the numbers in their simplest form. For example we have a number 90 : 70 then after writing it in the format of ratios now you have to bring out the common factors between the terms of ratios. So in this example we have 10 as a common factor. Thus you will divide both the numbers 90 and 70 by 10 so that you get the numbers in their simplest form so you will get 90/10:70/10 = 9:7.

Thus the ratio is 9:7.

Let’s take another example of three digits and three digits are 75 marks in biology, 25 marks in physics and 100 marks in maths. So let’s first write it in the form of ratio that is  

75 : 25 : 100

Now we need to follow the next step of how to solve ratios. That is to find out the common factor from all the numbers thus we can clearly see that 25 is the common factor so you will have to divide each number with 25.  

75/25 : 25/25 : 100/25  

= 3 : 1 : 4

Thus the answer is 3:1:4.

The important point to learn in ratio is that it does not change with the multiplication or division of same numbers. It will remain the same. For example if you multiply the above number with 2 then they will become 75 x 2 : 25 x 2 : 100 x 2 = 150 : 50 : 200. Now also the ratio is same if you convert it to the smallest form then like first you have to divide it by 50 then you will find get the same ratio that is 3:1:2.  

You can also find the value of variables if two ratios are equal. Let’s take an example to understand it better. Suppose you have one ratio 3:2 and other ratio 5:x and these two ratios are equal and now you are required to find the value of x song the equation will be  

3 / 4 = 3/X

3 x X = 3 x 2  

X = 6/3

X= 2.

Explanation:

The king of spades must be in the hand, and we can pick any other king. There are 3 ways to pick the other king. Then there are 4 C 2 = 6 ways to pick the two queens. The 4C2 refers to the nCr notation. Or you could use Pascal's Triangle.

Overall, there are 3*6 = 18 ways to pick the king of spades, another king, and exactly 2 queens.

Then we have one more card to pick that isn't a king nor a queen. There are 4+4 = 8 cards that are either a king or queen, leaving 52-8 = 44 cards that are neither.

So there are 18*44 = 792 ways to pick a king of spades, another king, exactly 2 queens, and some other card that isn't a king nor queen.

This is out of 52C5 = 2,598,960 possible five card hands.

The probability we're after is roughly 792/(2,598,960) = 0.0003047

The fuel-flow indicator rotor and needle in a motor-impeller and turbine indicating system are driven by a mechanism that measures and displays the rate at which fuel is flowing to the engine.

The fuel-flow indicator rotor and needle play a crucial role in providing real-time information about the rate of fuel consumption in an engine. The rotor is typically connected to a turbine or impeller, which is driven by the flow of fuel passing through it. As the fuel flows, it causes the rotor to rotate, and this rotational motion is then translated into the movement of a needle on the indicator display. The position of the needle corresponds to the fuel flow rate, allowing the operator or pilot to monitor and control the fuel consumption.

This indicating system is important for several reasons. Firstly, it enables operators to monitor fuel usage, ensuring that the engine is receiving an appropriate amount of fuel for efficient operation. Secondly, it provides valuable information for fuel management, allowing adjustments to be made if necessary to optimize performance or conserve fuel. Additionally, the indicator system helps identify any anomalies or irregularities in fuel flow, which can be indicative of potential issues or malfunctions within the engine or fuel system. Overall, the fuel-flow indicator rotor and needle serve as critical components in maintaining engine performance, efficiency, and safety.

After 35 minutes there will be 40 bacteria remaining.

The process of a constant percentage rate decrease in an amount over time is referred to as "exponential decay." The formula to calculate exponential decay is given as, \(N_t=N_0\left(\frac{1}{2}\right)^{\frac{t}{t_{1/2}}}\). Here, Nt is the quantity after time t, N0 is the initial quantity, t1/2 is the half-life, and t is time.

For the first situation, Nt=360, N0=900, t=10 minutes. Therefore, substituting the given values get the value of t1/2. So,

\(\begin{aligned}360&=900\left(\frac{1}{2}\right)^{\frac{10}{t_{1/2}}} \\\frac{360}{900}&=\left(\frac{1}{2}\right)^{\frac{10}{t_{1/2}}}\\0.4&=\left(\frac{1}{2}\right)^{\frac{10}{t_{1/2}}}\\ \ln(0.4)&=\frac{10}{t_{1/2}}\ln(0.5)\\t_{1/2}&=10\times\frac{\ln(0.5)}{\ln(0.4)}\\&=7.6\end{aligned}\)

Now, for the second situation,  Nt=40.  We have to find the time at which there will be 40 bacteria remaining. Then,

\(\begin{aligned}40&=900\left(\frac{1}{2}\right)^{t/7.6}\\0.04&=\left(\frac{1}{2}\right)^{t/7.6}\\\ln(0.04)&=\frac{t}{7.6}\ln(0.5)\\t&=7.6\times\frac{\ln(0.04)}{\ln(0.5)}\\&=7.6\times4.64\\&=35.26\\&\approx35\end{aligned}\)

To compute the error in the approximations to y (0.2), y (0.6), and y (1), you can calculate the absolute difference between the approximate values obtained using Euler's Method and the exact values.

To approximate the values of y(0.2), y(0.4), ..., y(1.0) using Euler's Method with a time step of h = 0.2, we can use the following iterative scheme:

k | \(t_k\) | \(y_k\)

0 | 0 | -3

1 | 0.2 | \(y_{1}\)

2 | 0.4 | \(y_{2}\)

3 | 0.6 | \(y_{3}\)

4 | 0.8 | \(y_{4}\)

5 | 1.0 | \(y_{5}\)

To find \(y_1, y_2, y_3, y_4,\) and \(y_5\), we can use the difference equation based on Euler's Method:

\(y_{k+1} = y_k + h * f(t_k, y_{k})\)

where, \(f(t_k, y_k)\) represents the derivative of y with respect to t at \((t_k, y_{k})\).

In this case, \(f(t_k, y_{k})\) = 7 - \(y_k\) * \(e^{(-y_{k})}\).

Using this formula, we can calculate the approximations as follows:

For k = 0:

\(t_0 = 0, y_0 = -3\)

For k = 1:

\(t_1 = 0.2\)

\(y_{1} = y_{0} + h * f(t_{0}, y_{0})\) = -3 + 0.2 * (7 - (-3) * \(e^{(-(-3))}\))

For k = 2:

\(t_2 = 0.4\)

\(y_2 = y_1 + h * f (t_1, y_1)\)

For k = 3:

\(t_3 = 0.6\)

\(y_3 = y_2 + h * f (t_2, y_2)\)

For k = 4:

\(t_4 = 0.8\)

\(y_4 = y_3 + h * f(t_3, y_3)\)

For k = 5:

\(t_5 = 1.0\)

\(y_5 = y_4 + h * f(t_4, y_4)\)

Performing these calculations will give us the values of y (0.2), y (0.4), ..., y (1.0) according to the given method.

(b) To find the exact solution using separation of variables, we start with the given differential equation:

\(y' = 7 - y * e^{(-y)}\)

Rearranging the equation:

\(dy / (7 - y * e^{(-y)}) = dt\)

Integrating both sides:

∫dy / (7 - y *\(e^{(-y)}\)) = ∫ dt

We can now solve this integral to find the exact solution y(t).

(c) To compute the error in the approximations to  y(0.2), y (0.6), and y (1), you can calculate the absolute difference between the approximate values obtained using Euler's Method and the exact values.

The function f(x) = \(x^2 e^{(-x^2)}\) has a maximum value at x = 0, which is a relative maximum point.

To find the relative maximum of the function f(x) =\(x^2 e^{(-x^2)}\), we can take its first derivative, set it to zero, and solve for x.

f(x) = \(x^2 e^{(-x^2)}\)

f'(x) = \(2x e^{(-x^2)} - 2x^3 e^{(-x^2)}\)

Setting f'(x) = 0, we get:

\(2x e^{(-x^2)} - 2x^3 e^{(-x^2)} = 0\)

\(2x e^{(-x^2)} (1 - x^2) = 0\)

This equation is true when either \(2x e^{(-x^2)} = 0\) or \(1 - x^2 = 0\).

Solving \(2x e^{(-x^2)} = 0\), we get x = 0.

Solving \(1 - x^2 = 0\), we get x = 1 or x = -1.

Now, we need to determine whether these values of x correspond to relative maximum, minimum, or inflection points.

To do this, we can use the second derivative test. The second derivative of f(x) is:

f''(x) = \(2e^{(-x^2)} - 4xe^{(-x^2)} - 4x^2e^{(-x^2)}\)

At x = 0, f''(0) = 2, which is positive. This means that f(x) has a relative minimum at x = 0.

At x = 1, f''(1) = \(-6e^{(-1)}\), which is negative. This means that f(x) has a relative maximum at x = 1.

At x = -1, f''(-1) = \(-6e^{(-1)}\), which is negative. This means that f(x) has a relative maximum at x = -1.

Therefore, the answer is (D) -1 and 1 only, as these are the only values of x at which f(x) has a relative maximum.

P(54 < X1 + X2 + X3 < 72) is approximately 0.8972.

-The sum of independent normal random variables is also a normal random variable. Therefore, X1 + X2 + X3 is also a normal random variable with mean

E(X1 + X2 + X3) = E(X1) + E(X2) + E(X3) = 10 + 20 + 30 = 60 and variance Var(X1 + X2 + X3) = Var(X1) + Var(X2) + Var(X3) = 12.

So, X1 + X2 + X3 ~ N(60, 12).

-To find P(54 < X1 + X2 + X3 < 72), we standardize the random variable as follows:

\(Z = \frac{(X1 + X2 + X3 - 60)}{\sqrt{12} }\)

-Then, we need to find \(p(\frac{(54-60)}{\sqrt{120} } < Z < \frac{(72-60)}{\sqrt{12} }\).

Step-by-step explanation:

Take the law if sines of a triangle:

\( \frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC} \)

Where,

a = 28 miles

B = 25°

b = 12 miles

First solve for A, using the law of sines:

\( \frac{a}{sinA} = \frac{b}{sinB} \)

\( \frac{28}{sinA} = \frac{12}{sin25} \)

Cross multiply:

\( 28 sin25 = 12 sinA \)

\( 11.83 = 12 sinA \)

\( Sin A = \frac{11.83}{12} \)

\( Sin A = 0.986 \)

\(A = sin^-^1(0.986)\)

\( A = 80.44 degrees \)

Since A = 80.44° find A supplement, A`:

A` = 180 - 80.44

A` = 99.56°

If A` + B < 180°, find C.

Thus,

We can conclude that there is not enough evidence to suggest that the variance of the sodium content differs between the two brands.

The problem provides measurements of the sodium content in samples of two brands of chocolate bar. To find if there is a difference in variance between the two brands, we can conduct a two-sample F-test for equality of variances at a 0.05 significance level.

The following is the null and alternative hypotheses for the test:

H0: The variances of sodium content in brand A and brand B are equal.

H1: The variances of sodium content in brand A and brand B are different.

If the test statistic is greater than the critical value, we reject the null hypothesis. Otherwise, we fail to reject the null hypothesis.

Using the data given, we find the sample variances for both brand A and B:

Variance of Brand A, s2A = 9.84

Variance of Brand B, s2B = 8.45

We calculate the F-statistic:

F = s2A / s2B = 1.16

The degrees of freedom for both brand A and B are dfA = 8 and dfB = 12 respectively.

We then find the critical values of F from an F-distribution table for dfA = 8 and dfB = 12, and at a 0.05 significance level. The critical values are 0.240 and 3.053 respectively.

Since our test statistic F = 1.16 is less than the critical value 3.053, we fail to reject the null hypothesis.

Therefore, we can conclude that there is not enough evidence to suggest that the variance of the sodium content differs between the two brands.

Thus, the chocolate bars of both brands can be assumed to have the same variance for sodium content.

The x-axis is the horizontal center line on the coordinate plane (left to right). The y-axis is the vertical center line on the coordinate plane. The point where the x and y axis interact, identified by 0, is called the origin.

This point is located at coordinates (0,0). The x-axis is usually associated with the horizontal axis in a two-dimensional graph and is typically used to represent different categories of data. The y-axis is associated with the vertical axis and is used to represent a range of values from high to low.

The formula for determining the coordinates of a point is (x,y). The x-coordinate is the distance from the origin on the x-axis and the y-coordinate is the distance from the origin on the y-axis. For example, if a point has an x-coordinate of 4 and a y-coordinate of -3, the coordinates of the point would be (4,-3). To calculate the distance between two points, you can use the distance formula, which is the square root of the sum of the squares of the differences between the x-coordinates and the y-coordinates. For example, if the coordinates of point A are (2,3) and the coordinates+ of point B are (7,1), the distance between A and B would be calculated by taking the square root of (5-2)^2+(1-3)^2, which would equal 5.
