Given:

The regression equation is:

[tex]y=-25x+436[/tex]

The given point is (17,3.8).

To find:

The residual for the given point.

Solution:

We have,

[tex]y=-25x+436[/tex]

Substituting [tex]x=17[/tex], we get

[tex]y=-25(17)+436[/tex]

[tex]y=-425+436[/tex]

[tex]y=11[/tex]

The predicted value at [tex]x=17[/tex] is 11.

The given point is (17,3.8). It means the observed value at [tex]x=17[/tex] is 3.8.

Formula for residual:

Residual = Observed value - Predicted value

Residual = [tex]3.8-11[/tex]

Residual = [tex]-7.2[/tex]

Therefore, the residual for the given point is -7.2.

Answer:

Y=75     x=75

Step-by-step explanation:

This is a scalene triangle and the total of the degrees will always be 180. So 180-30=150

since there are two sides split 150 in 2. 150 divided by 2 = 75

Answer:

[tex]V=497.16\ cm^3[/tex]

Step-by-step explanation:

The attached figure shows a cone of radius 5 cm and height 19 cm. The formula for the volume of a cone is given by :

[tex]V=\dfrac{1}{3}\pi r^2h[/tex]

Substitute all the values,

[tex]V=\dfrac{1}{3}\times 3.14\times 5^2\times 19\\\\V=497.16\ cm^3[/tex]

So, the volume of the cone is equal to [tex]497.16\ cm^3[/tex].

Step-by-step explanation:

[tex] \large{\red{\underline{\bf{Required \: Solution \: : }}}} [/tex]

Here we have been provided with two equations and we have to solve them by substitution method and get the value of x and y.

Here we have been already provided a temporary value of y in first equation so let us substitute in the second equation.

[tex]: \implies \: \sf{y \: = \: 4x \: - \: 10}[/tex]

[tex]: \implies \: \sf{x \: - \: 4 \: = \: 4x \: - \: 10}[/tex]

[tex]: \implies \: \sf{x \: = \: 4x \: - \: 10 \: + \: 4}[/tex]

[tex]: \implies \: \sf{x \: = \: 4x \: - 6}[/tex]

[tex]: \implies \: \sf{x \: - 4x \: = \: - 6}[/tex]

[tex]: \implies \: \sf{ - 3x \: = \: - 6}[/tex]

[tex]: \implies \: \sf{ \cancel - \: 3x \: = \: \cancel- \: 6}[/tex]

[tex]: \implies \: \sf{ 3x \: = \: 6}[/tex]

[tex]: \implies \: \sf{ x \: = \: \dfrac{6}{3} }[/tex]

[tex]: \implies \: \sf{ x \: = \: \cancel\dfrac{6}{3} }[/tex]

[tex]: \implies \: \boxed{\bf{ x \: = \:2 }} \pink\bigstar[/tex]

Therefore, value of x is 2..!!

Finding out value of y :

Here we would substitute the value of x which we got as 2 in the first equation inorder to get the value of y.

[tex]: \implies \: \sf{ y \: = \: x \: - \: 4 }[/tex]

[tex]: \implies \: \sf{ y \: = \: 2 \: - \: 4 }[/tex]

[tex]: \implies \: \boxed{\bf{ y \: = \:-2 }} \pink\bigstar[/tex]

Therefore, value of y is -2.

Answer:

the answer to this question is seven

Answer:

27

Step-by-step explanation:

2 is vertical to 1, making it 27 as well. then, 4 is corresponding to 4, making it 27

Answer:

27°

Step-by-step explanation:

angle 1 is vertically opposite to angle 2

angle 2 is correspondence to angle 4

vertically opposite and corresponding angles are equal

Step-by-step explanation:

Given

5y + 68 = 3y + 96 (vertically opposite angles) and

3x + 18 = 5x + 2 (vertically opposite angles)

Now solve for x.

[tex]3x + 18 = 5x + 2 \\ 3x + 18 - 5x = 2 \\ - 2x + 18 = 2 \\ - 2x = 2 - 18 \\ - 2x = - 16 \\ x = - 16 \div - 2 \\ = 8[/tex]

Now Solve for y.

[tex]5y + 68 = 3y + 96 \\ 5y + 68 - 3y = 96 \\ 2y + 68 = 96 \\ 2y = 96 - 68 \\ 2y = 28 \\ y = 14[/tex]

Answer:

The area of a triangle is 1/2BH, or 1/2 times the base times the height.

If the area = 6, and B and H must both be whole numbers.

The area of the triangle ΔSTU is given by A = 12 units²

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the area of the triangle ΔSTU be represented as A

Now , the area of triangle ΔQTU is 6 square units, and the area of triangle ΔRSU is 6 square units

So , the base of the triangle ΔSTU = 6 units

The height of the triangle ΔSTU = 4 units

So , area of the triangle = ( 1/2 ) x Length x Base

On simplifying , we get

The area of triangle ΔSTU = ( 1/2 ) x 4 x 6

The area of triangle ΔSTU = 12 units²

Therefore , the value of A is 12 units²

Hence , the area of the triangle is 12 units²
