The perimeter of the given right-angle triangle is 40 cm.

In a right-angled triangle, the sum of the squares of the smaller two sides of a right-angle triangle is equal to the square of the largest side.

We also know that the perimeter of a triangle is the sum of the lengths of all the sides.

First, we need to figure out the length of the base of the right-angle triangle.

Assuming the base to be 'x'.

∴ 17² = 15² + x².

x² = 17² - 15².

x² = 64.

x = ± 8.

So, The base of the triangle is 8 cm.

∴ The perimeter of the triangle is (17 + 15 + 8) = 40 cm.

Two numbers are in the ratio 4: 7. If their L.C.M. is 168,The numbers would be 56 and 98.

The smallest positive integer that is divisible by both a and b is known as the least common multiple (lcm) in mathematics and number theory. It can also be referred to as the lowest common multiple (lcm), or the smallest common multiple of two numbers (a and b).

The given ratio is 4:7, which can be written as 4/7.

To find the individual numbers, we can use the formula:

Number1 = LCM × Ratio1/ (Ratio1 + Ratio2)

Number2 = LCM × Ratio2/ (Ratio1 + Ratio2)

Therefore,

Number1 = 168 × 4/ (4 + 7) = 56

There are infinitely many solutions to an equation with two variables.

We know that an equation is a mathematical statement that contains equal symbol between two mathematical expressions.

In this question need to solve  an equation with x and y in one equation.

Consider an equation with two variables: 5x + y = 8

If we solve given equation for x then it would be,

5x + y = 8

5x + y - y = 8 - y

5x/5 = (8 - y)/5

x = (8 - y)/5

for any arbitrary real value value of y we can find the value of x.

This means there are infinitely many solutions.

If we solve given equation for y then it would be,

5x + y = 8

5x + y - 5x = 8 - 5x

y = 8 - 5x

for any arbitrary real value value of x we can find the value of y.

Therefore, an equation with two variables has infinitely many solutions.

The required chances to win the game is more than 50% no matter what two are.

The  probability is the proportion of the likelihood of an occasion to occur. It estimates the conviction of the occasion. The recipe for likelihood is given by; P(E) = Number of Ideal Results/Number of all out results.

Allow the two numbers to be an and b, with a<b. Look at an acknowledgment of X (free of your decision of an or b) with the worth of the main number you see. Assuming that X is greater, switch, in any case keep the number.

The likelihood of winning can be registered as follows:

In the event that you pick a (with 12 possibility), you win assuming you switch, ie if X>a. This has prob. P(X>a).

Comparably assuming you pick b (with 12 possibility), you win on the off chance that you don't switch, ie if X≤b. This has prob. P(X≤b).

So the general likelihood of winning is 1/2+1/2P(a<X≤b), which is marginally bigger than 1/2 in view of our presumptions on X.

Possibility is referred to as probability. This branch of mathematics deals with the occurrence of a random event. The value's range is 0 to 1. Probability has been applied into mathematics to predict the likelihood of different events. Probability generally refers to the degree to which something is likely to occur. This fundamental theory of probability, which also applies to the probability distribution, can help you comprehend the possible outcomes for a random experiment.

The difference between the predicted regression value and the actual value is called the residual.

Let's assume a simpler model: Y= β₀+ β₁X + E. For linear regression, let ε∼N(0,σ2). The most important thing here is that ϵ is a normal random variable. This makes Y a normal random variable with mean β0+β1X and variance σ₂.

Regression Analysis:

Regression analysis is a set of statistical techniques used to estimate the relationship between a dependent variable and one or more independent variables. It can be used to assess the strength of relationships between variables and model future relationships between variables.

Assumptions:

One of the main assumptions of regression analysis is that residuals with mean equal to 0 are normally distributed. Residuals must be both positive and negative. If this condition is not met (residuals are only positive or negative, i.e. the model is either consistently Regardless, it means that it has not been properly selected for prediction.

Poor predictions are due to (i) the regression model should contain non-linear terms rather than only linear terms, (ii) multicollinearity of the independent variables, and (iii) missing important predictor variables (features). Poor understanding of the problem and data, (iv) non-constant data variance, or (v) extrapolation (prediction) far beyond the range of the independent variables used to estimate the parameters of the model.

Given, two flocks of birds are 210 miles apart and heading directly toward each other. one flock is flying at a rate of 25 miles per hour.

In comparison, the other flock is flying at a rate of 37 miles per hour.

We have to find in how much time will the two flocks meet.

Let, both take t hours to meet,

now, according to the question

first flock will travel the distance, 25t

and similarly second flock will travel the distance, 37t

so, 25t + 37t = 210

The rate at which the water level is rising when the water is 6 inches deep is  4/5 ft/min .

In the question ,

it is given that ,

the length of the trough is = 10 ft ,

the width is  (w) = 3 ft ,

the height of the trough is (h) = 1 ft ,

we get the relation between width and height is w = 3h ;

The formula for Volume is written as = Area of triangle * length

= 1/2 × h × w × l

= (1/2) × 3h × h × 10

So , V = 15h² .

Differentiating the given with respect to time "t" ,

we get ,

dV/dt = 30×h×dh/dt  

given that , the trough is being filled with water at a rate of 12ft/min,

that means ,

dV/dt = 12

So , the rate of change of water level when the water is 6 inches deep can be calculated using the formula .

we know that 6 inches = 6/12 ft

12 = 30×(6/12)×dh/dt  

dh/dt = 12/15 = 4/5 ft/min
