A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other

What is an equivalent ratios?

A ratio compares two quantities named as antecedent and consequent, by the means of division. For example, when we cook food, then each ingredient has to be added in a ratio. Thus, we can say, a ratio is used to express one quantity as a fraction of another quantity.

Two ratios are equivalent to each other if one of them can be expressed as the multiple of the other. Hence, to get the equivalent ratio of another ratio, we have to multiply the two quantities (antecedent and consequent) by the same number.

Given ratios are 2:1 and 3:1

we can write it as 2/1 and 3/1.

The lcm of 2 and 3 is 6.

Multiply denominator of both ratio with 6, we get

2/6 and 3/6 And we can see both the ratios are not equal.

Hence, there are not equivalent ratios.

4:1 and 8:3 are equivalent ratios -----> is false, because 4:1 is equivalent to 8:2

11:2 and 2:11 are equivalent ratios------> is false (because, are reciprocal ratios, not equivalent ratios)

3:1 and 9:3 are equivalent ratios ------> is true

because 3:1 multiply both sides by 3 -----> 3*3:1*3=9:3

The slope of the line in 1. is -3/4 and the slope of 2. is 9/10.

Understanding what slope is is among the most crucial things to know about lines. The line's slope, also referred to as rise over run, is how "steep" it is. By dividing the difference between the y-values at two points by the difference between the x-values, we can determine slope. Understanding how to interpret graphs and create equations is necessary in order to comprehend the significance of the definition of slope.

The slope of the line = m in y = mx + b

−3x−4y=6

4y = -3x -6

y = (-3x -6)/4

y = -3x/4 -6/4

y = -3/4(x) -3/2

2. Slope formula = y₂ - y₁ = m(x₂ -x₁)

points (6, -1) and (-4, -10)

The value of c in the quadratic = 1.

From this equation, we can easily see that for this equation to have one possible answer, this equation must be a perfect square trinomial, which results from an equation of the form [tex](x+1)^{2}[/tex].

We also know that [tex]b+\frac{1}{b}[/tex]  is equal to the sum of the roots (since the coefficient of [tex]x^{2} = 1[/tex]) and the product of the roots = c.

We easily know that in a quadratic [tex]ax^{2} +dx+c=0[/tex], if this quadratic is a square, then [tex]\frac{d}{c} = \frac{2\sqrt{c} }{c}[/tex]

[tex]2\sqrt{c} = b + \frac{1}{b}[/tex]

We know that c is a perfect square, so that means [tex]b+\frac{1}{b}[/tex] has to have an integer value, and the only way this is possible is if b = 1.

Therefore, if b = 1,

[tex]2\sqrt{c} = b + \frac{1}{b}\\\sqrt{c} = 1\\c = 1[/tex]

Therefore, the value of c in the quadratic = 1.

Answer:Three functions that are bounded above are y = x^2, y = x^3, y = e^x.

y = x^2 is a parabola that opens upward and has a vertex at the origin (0,0). As x increases or decreases, y will always be positive and increases or decreases accordingly, so the function is bounded above by positive infinity.

y = x^3 is a cubic function that also opens upward. As x increases or decreases, y will always be positive and increases or decreases accordingly, so the function is bounded above by positive infinity.

y = e^x is the exponential function where e is Euler's number (approximately 2.718). As x increases, y will increase towards positive infinity, so the function is bounded above by positive infinity.

By applying independent and disjoint events theory, it can be concluded that A and B are neither disjoint nor independent (option D).

In probability, based on the occurrences, there are two types of events: independent and disjoint events.

Now we observe the data given:

p(a) = 0.3

p(b) = 0.2

p(a and b) = 0.4.

First, we check the independence. Here p(a and b) = 0.4. Whereas, if a and b are independent events, then:

p(a and b) = p(a) * p(b)

                = 0.3 * 0.2

                = 0.06

Since the value is different, we can conclude that events A and B are not independent.

Second, we check whether these events are disjoint events. Since the value of p(a and b) is not 0, these events are disjoint events.

Therefore, we can conclude that a and b are neither disjoint nor independent (option D)

The probability of a “full house” is 6 / 4165.

Probability is a measure of the likelihood of a particular event occurring. It is expressed as a number between 0 and 1, where 0 indicates that an event is impossible and 1 indicates that an event is certain to occur.

For example, the probability of flipping a fair coin and it landing on heads is 0.5, or 50%. The probability of rolling a fair die and getting a 6 is 1/6, or about 16.67%.

A “full house” (3 cards of one kind and 2 cards of another kind)

Since there are 13 sets of each type, we have to select any 2 kinds of it.

The probability becomes =[tex]\frac{2 X 13C2 X4C3X 4C2 }{52 C5}[/tex]

On simplification,

height = 14.5 ft and width = length = 3.2 ft  in a box with the largest possible volume

Let the side of the square base is a and the height of the box is h.

The material required to make the box is equal to the total surface area of the box.

Area of base = a²

Cost of square base is $ 2 per ft²

So, the cost of making base = 2a²

Area of four walls + area of top = 2 (a² + ah + ah) + a² =  3a² + 2ah

Cost of making walls and the top is $ 1 per ft²

So, the cost of making walls and the top = 1 x ( 3a² + 2ah)

Total cost of making the box = 2a² + 3a² + 2ah = 5a² + 2ah

According to the question

144 = 5a² + 2ah

    .... (1)

The volume of the box is V = length x width x height

V = a x a x h

The point at which a graph crosses the y-axis is known as the y-intercept. It is, in other words, the value of y when "(x=0)" occurs. Using the slope and a specified location, determine the y-intercept of a linear function.

Determine the graph's gradient and a point first. Enter a linear equation in slope-intercept form (y = mx + b) once this is finished. Rewrite the equation using the supplied point (x, y) and slope (m), inserting the correct values for x, y, and m.

The function is:

f(x) = (9x^2 - 36)/3x + 6

Simplify that function to a linear function for all x for which 3x + 6 ≠ 0

3x = - 6

x = -2

So, for x ≠ - 2, you can do:

f(x) = (9x^2 - 36) /   3x + 6

f(x) = 9(x^2 - 4) /   3x + 6

f(x) = 3(x + 2)(x - 2) / x+2

f(x) = 3(x - 2) = 3x - 6

In the given question,

Let the length and breadth of the rectangular part of the window be 2l and 2b respectively. So the radius of the semicircular arc will be l.

The total perimeter of the window will be 1 length of the rectangle, 2 breadths of the rectangle, and the length of the semicircular arc.

l+2b+πl = 10

(1+π)l+2b = 10

[tex]b = \frac{1}{2} [10-(1+\pi )l][/tex]

To admit maximum light through the window implies that the area of the window is maximized.

The area of the window will be:

[tex]A = (2l)(2b)+\frac{\pi l^{2} }{2}[/tex]

[tex]= 4lb+\frac{\pi l^{2} }{2} \\= 2l[10-(1+\pi )l] +\frac{1}{2} \pi l^{2}[/tex]

[tex]= 20l-2l^{2} -2\pi l^{2} +\frac{1}{2} \pi l^{2}[/tex]

[tex]= 20l-2l^{2} - \frac{3}{2} \pi l^{2}[/tex]

For the area to be maximum,

[tex]\frac{dA}{dl} =0\\20 -4l -3\pi l = 0\\l= \frac{20}{4+3\pi }[/tex]

[tex]b = \frac{1}{2} [10-(1+\pi )\frac{20}{4+3\pi }\\b = \frac{10+5\pi }{4+3\pi }[/tex]

As the sample size becomes larger, the sampling distribution of sample mean approaches a normal distribution.

As the sample size becomes larger, the sampling distribution of the sample mean approaches a normal distribution. This is known as the Central Limit Theorem. The Central Limit Theorem states that as the sample size increases, the sampling distribution of the sample mean becomes more and more normal, regardless of the shape of the underlying population distribution. The sample mean is an unbiased estimator of the population mean and it follows a normal distribution when the sample size is large.

The binomial distribution is a probability distribution that describes the number of success in a fixed number of trials, each with the same probability of success. While the binomial distribution is used to model the number of successes in a fixed number of trials, it is not used to model the sample mean.
