What is Regression line?

An estimate of the line that depicts the actual, but unidentified, linear relationship between the two variables is called a regression line. When the value of the explanatory variable is known, the regression line's equation is used to predict (or estimate) the value of the response variable.

Given:

Using the regression model

In II nd week the calories is 2950 and weight 250.

and, Vth week the calories is 7400 and weight 216.

let Exercise be x and the weight is y then

= (216 - 250)/ (7400- 2950)

= -9/ 4450

So, at the start of week john weight

y= -9/ 4500 x + 230

Now, At the end of 8 week John weighs

= -9/4500 (6100) + 230

= 217.7

Answer: yea its 123445

Step-by-step explanation:

1,-1,-3 are the zeroes and the relationship between zeroes and the coefficient is verified.

What is a Polynomial?

Polynomial, a mathematical expression made comprised of numbers and variables arranged in specific patterns.

As per the given data:

We are given the equation of a cubic polynomial x³ + 3x² - x - 3.

The zeroes of the given cubic polynomial are also given.

We have to verify that the zeroes of the cubic polynomial are correct, and they satisfy the relationship between zeroes and the coefficient.

For a polynomial p(x) is p(a) = 0 then a is a zero of p(x).

Checking the given zeroes similarly:

For 1:

1³ + 3(1)² - 1 - 3 = 0

1 + 3 - 1 - 3 = 0

0 = 0

1 is a zero

For -1:

(-1)³ + 3(-1)² - (-1) - 3 = 0

-1 + 3 + 1 - 3 = 0

0 = 0

-1 is a zero

For -3:

(-3)³ + 3(-3)² - (-3) - 3 = 0

-27 + 27 + 3 - 3 = 0

0 = 0

-3 is a zero

For ax³ + bx² + cx + d = 0, the sum of all the roots should be equal to

= (-b)/a

Similarly, for x³ + 3x² - x - 3:

1 + (-1) + (-3) = (-3)/1

1 - 1 - 3 = -3

-3 = -3

1,-1,-3 are the zeroes and the relationship between zeroes and the coefficient is verified.

Hence, 1,-1,-3 are the zeroes and the relationship between zeroes and the coefficient is verified.

A man is 32 years older than his daughter and the product of their ages is 320..
(a) Find the ages of the man and the daughter.
(b) In how many years' time will the daughter's age be one- third of her father's age?

Pls help me

Answers

a) the man is 40 and the daughter is 8
b)in 8 years when the man is 48 and the daughter is 16

The age of the man is 40 years and that of his daughter is 8 years respectively.

How to solve a linear equation?

A linear equation can be solved by equating the LHS and RHS of the equation following some basic rules such as by adding or subtracting the same numbers on both sides and similarly, doing division and multiplication with the same numbers.

Suppose the age of man be x.

Then, age of his daughter is x - 32.

As per the question the following equation can be formed for the product of ages as ,

x(x - 32) = 320

⇒ x² - 32x - 320 = 0

⇒ x = 40, -8

Since, age of a person cannot be a negative value, it is taken as positive.

Thus, the age of daughter is 40 - 32 = 8

Hence, the age of the man and his daughter is obtained as 40 and 8 years respectively.

Answers

Answer:

m<2 = 120

Step-by-step explanation:

When two lines are parallel and are intersected by a transversal, same side exterior angles are supplementary, meaning that their angle measures add up to 180 degrees.

Using this, one can form the equation;

m<8 + m<2 = 180

Substitute,

60 + m<2 = 180

Inverse operations,

60 + m<2 = 180

-60 -60

m<2 = 120

Answer:

Step-by-step explanation:

Solution

<8 = 60 degrees.

<6 is <8s supplement

<6 + <6 = 180

60 + <6 = 180

<6 = 180 - 60

<6 = 120

<2 and <6 are corresponding angles and are therefore equal.

<2 = 120

Pretty sure you have to use the Pythagorean Theorem.
a^2+b^2=c^2

So you would plug in your numbers that you already have (6 and 10) But notice that 10 is the hypotenuse (longest side) so
6^2+x=10^2

Then you would solve it and you should end up with 11.6619

Answer:

Each shelter would get 121 blankets

And there would be 5 blankets left over

Step-by-step explanation:

From the above question

7 local shelters = 852 blankets

1 local shelters = x blankets

Cross Multiply.

7x = 852 blankets

x = 852 blankets/7

x = 121 5/7 blankets

Therefore, Each shelter would get 121 blankets

And there would be 5 blankets left over

Angles A and Care supplementary. Find the measure of angle C.
There is a picture

Answers

Answer:

106 degrees

Step-by-step explanation:

180 -74 = 106

The second option is correct i.e. [tex]m[/tex]∠C = 106 degrees.

What are supplementary angles?

Two angles are said to be supplementary angles when they add up to 180 degrees.

Two angles are supplementary, if

a). one of its angle is an acute angle and another angle is an obtuse angle.

b). both of the angles are right angles.

This means that if A and B are the two angles then

[tex]m[/tex]∠A+[tex]m[/tex]∠B = 180 degrees

According to the given question we have

angles A and C are supplementary

and, [tex]m[/tex]∠A = 74 degrees

therefore,

the measure of angle C is calculated as

[tex]m[/tex]∠A + [tex]m[/tex]∠C = 180 degrees (sum of the supplementary angles)

74 + [tex]m[/tex]∠C = 180 degrees ( [tex]m[/tex]∠A = 74 )

[tex]m[/tex]∠C = (180 - 74)degrees ( subtracting 74 degrees both the sides)

[tex]m[/tex]∠C = 106 degrees

Hence, second option is correct i.e. [tex]m[/tex]∠C = 106 degrees.

There are certainly many positive reasons for having students wear them. If students were uniformly dressed, there would be less distractions about clothing, adding more focus on academics. Another reason to add uniforms is that there would no longer be conflict over how young people dress. There would be no singling out of poorer students who cannot wear designer labels, and young people wouldn't have to worry so much about fitting in because of how they dress. Opponents, however, say requiring school uniforms suppresses a young person's need for individuality. This simply isn't the case, though, as students can use hairstyle, jewelry, and so on to show their individuality.
