Find the value of angle A and B!! Will mark brainliest

Answer

The  value is  [tex]P = 131.07[/tex]

Step -by -step -explanation :

 From the question we are old that

         The sample size is  n =  20  

         The sample mean for the first person of each twin is  [tex]\= x = 100.45[/tex]

         The sample mean for the second person of each twin is  [tex]\= y = 103[/tex]

          The  correlation between both data is  r =  0.908

         The p-value is  p-value  =  0.000

          The  equation  [tex]\^ y = 13.47 + 1.12 x[/tex]

Here we are told that x represents  the first person to be given birth to among each twin  

       The value of x  considered is  x = 105

          Generally given that p-value  =  0.000

Then  the  Predicted value of  [tex]\^ y[/tex]  is mathematically represented as

           [tex]P = 13.47 + 1.12 (105)[/tex]

=>         [tex]P = 131.07[/tex]

A

Step-by-step explanation:

two of the triangles' corresponding angles are the same even if the side lebgths are not, making these two similar

By AA similarity triangle ABC and triangle LMN are similar. Therefore, option A is the correct answer.

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

In the given triangle ABC, ∠A=50° and ∠B=75°.

In the given triangle LMN, ∠L=50° and ∠M=75°

From the given triangles,

∠A=∠L=50°

∠B=∠M=75°

By AA similarity triangle ABC and triangle LMN are similar.

Therefore, option A is the correct answer.

Answer:

Step-by-step explanation:

Given that :

Voucher awarded (x) :

Repair = $50

Lose or destroy = $200

P(x):

Replacement voucher = 5%

Repair voucher = 10%

X ______ 50 ______ 200

P(x) ____ 0.1 _______ 0.05

Expected variance Var(X) :

ΣX²p(x) - E(x) ;

E(x) = Σx*p(x) = (50*0.1) + (200*0.05) = 15

ΣX²p(x) = Σ[(50^2 * 0. 1) + (200^2 * 0.05)] = 250 + 2000 = 2250

Var(X) = 2250 - 15^2 = 2025

Standard deviation = √Var(x)

Standard deviation = √2025

Standard deviation = $45

HL

Step-by-step explanation:

The hypotenuse and the "leg" are congruent...along with the 90 degree angle.

"The HL Postulate states that if the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the two triangles are congruent." - Calcworkshop

Explanation:

Of course, the plumber might not want a haircut, but he might have a wife, a fiancee, or a sister who may need the services of a hairdresser so working for the hairdresser would earn him credit that can be used by any of these people. So in a sense, he is getting things done for others.

Therefore, the time-bank service solves a problem by allowing people to receive services without exchanging money.

Answer:

I am thinking it is distributive property

Answer:

x = 8

Step-by-step explanation:

Interior angles of a triangle always add up to 180 degrees.

50 + 76 + ? = 180

? = 180 - 126

? = 54

A straight line also is always 180 degrees.

54 + 15x + 6 = 180

15x = 180 - 60

15x = 120

x = 8

Given:

The relations in the options.

To find:

The relation which is a function.

Solution:

Consider the options are :

(a) {(2, 7), (6, 5), (4, 4), (3, 3), (2, 1)}

(b) {(9, −3), (9, 3), (4, −2), (4, 2), (0, 0)}

(c) {(1, 0), (3, 0), (1, 1), (3, 1) (1, 3)}

(d) {(1, 1), (2, 2), (3, 3), (4, 4), (5, 8)}

A relation is a function if there exist a unique y-value for each x-value.

In option (a), y=7 and y=1 at x=2. So, it is not a function.

In option (b), y=-3 and y=3 at x=9. So, it is not a function.

In option (c), y=0 and y=1 at x=3. So, it is not a function.

In option (d), there are unique y-value for each x-value. So, it is a function.

Therefore, the correct option is (d).

Answer:

4.2 you should use a calculator for these

Step-by-step explanation:

Answer: When a point or figure on a coordinate plane is moved by sliding it to the right or left or up or down, the movement is called a translation. The figure is translated from one position to another. Example 1: A point is located at (3, 7) on the coordinate plane. In geometry, a translation is the shifting of a figure from one place to another without rotating, reflecting, or changing its size. This is done by moving the vertices of the figure to the prescribed number of spaces on a coordinate plane and then drawing the new figure. There are four main types of transformations: translation, rotation, reflection, and dilation. These transformations fall into two categories: rigid transformations that do not change the shape or size of the preimage and non-rigid transformations that change the size but not the shape of the preimage.
