What is the regression coefficient bxy from the following details X = 7/3Y + 28.10; Y = 1.5x + 10

Answer»

Given : X = 7/3Y + 28.10; Y = 1.5x + 10

To find : regression coefficient BXY

Solution:

The slopes of the equation Y on X are DENOTED as byx and

The slopes of the equation X on Y are denoted bxy .

byx and bxy are the coefficient of regression

X = 7/3Y + 28.10

bxy = 7/3

regression coefficient bxy = 7/3

Y = 1.5x + 10

byx = 1.5

10. Using the graph of y=x2-3x- 10. What is the correct way to write the solution ofx2-3x-10 < 0? ?A. {x52}u**25)B. 2

Answer»

Given : y = x² - 3x - 10

To Find : solution of x² - 3x - 10 < 0

Solution:

y = x² - 3x - 10

=> y = x² - 5x + 2x - 10

=> y = X(x - 5) + 2(x - 5)

=> y = (x - 5)(x + 2)

x² - 3x - 10 < 0

=> (x - 5)(x + 2) < 0

x = 5 , -2 => y = 0

x > 5 => y = (+)(+) = + > 0

-2 < x < 5 => y = (-)(+) = - < 0

x < - 2 => y = (-)(-) = + >0

Hence x ∈ ( - 2 , 5 )

Mention the kind of triangle also.7. The angle of a triangle is in the ratio of 2: 3: 4. Find the measure of each angle of the triangle.loo of an isosceles triangle measures 55°. Determine the other angles.

Answer»

Answer:

The angle of a TRIANGLE is in the RATIO of 2: 3: 4. Find the MEASURE of each angle of the triangle.

Let the 3 angles of the triangle be 2x 3x and 4x.

sum of MEASURES of a triangle = 180°

Therefore 2X +3x+4X= 180°

9X = 180°

X=180°/9

X = 20°

Angle 1 = 2X= 2×20°= 40°

Angle 2= 3X= 3×20° = 60°

Angle 3 = 44X= 4× 20° = 4x20° =80°

The age of Rajesh is 7 more than the thrice of the age of his son . After 5 years age of Rajesh will be 3 less than the thrice of the age of his son. If ratio of age after 5 years becomes 5:14 then find the age of Rajesh and his son.

Answer»

Answer:

Let the SON's age be x

Then , according to the condition,

father's age =3x+3

3 years LATER:

Son's age =x+3

Father's age =3x+3+3=3x+6

According to the condition GIVEN ,

3x+6=10+2(x+3)

3x+6=10+2x+6

x=10

Thus , the son's present age is 10 years and the father's age is

3x+3=3×10+3=33 years.

<P>ANSWER:

question is not very clear

i HOPE question is

MULTIPLY the following:

6-7 by p+z

Answer is ( - p + z)

$- 1 \times (p + z) = ( - p + z)$

Step-by-step explanation:
