math

Answer 2

Answer:

1. x = 42

2. y = 46

3. z = 0

Step-by-step explanation:

1. 45 + x = 87

         subtract 45 from both sides

  x = 42

2. y - 31 = 15

         add 31 to both sides

  y = 46

3. 5z = 0

         divide 5 from both sides

  z = 0/5

         since any fraction with a numerator of 0 is equal to 0, we get

  z = 0

In a test of hypothesis for a mean, which statement is CORRECT?

The population must be normal because that is the only case when the sample mean is Normally distributed.
As long as the population distribution consists only of positive values, sample size does not matter.
The population distribution can be any distribution because the sample mean is always Normally distributed.
The test requires that the sample mean is normally distributed; this requires that either the population distribution is Normal or the sample size exceeds 30.

Answers

Answer:

As long as the population distribution consists only of positive values, sample size does not matter.

Step-by-step explanation:

As long as the population distribution consists only of positive values, sample size does not matter.

This is a hypothesis because a hypothesis is basically a prediction of what's gonna happen; the other choices are mostly facts that can be backed up, this can only be confirmed after it happens since it can end in different ways. This is a prediction where it says that if the population distribution continues to go on to positive value, then the sample size won't matter; this can come out in different ways, the sample size could matter or it would have to be negative values, e.t.c. This has different ways it could end up.

Irene is making bags of trail mix for hiking club. She will use 22 ounces of walnuts, 11.2 ounces of
almonds, and 12.3 ounces of cashews. This amount makes 25 bags of trail mix. How many
ounces are in each bag?




Please help :/ if i dont finish theses questions i will go to summer school & i dont wanna go there

Answers

Answer:

In each bag there will be 1.82 ounces of mixture.

Step-by-step explanation:

Since Irene is making bags of trail mix for hiking club, and she will use 22 ounces of walnuts, 11.2 ounces of almonds, and 12.3 ounces of cashews to make 25 bags of trail mix, to determine how many ounces are in each bag you must perform the following calculation:

(22 + 11.2 + 12.3) / 25 = X

45.5 / 25 = X

1.82 = X

Thus, in each bag there will be 1.82 ounces of mixture.

Triangle ABC maps to triangle A′B′C′ by a 90∘ rotation counterclockwise about the origin.

If AB=61 units, BC=11 units, and AC=60 units, what is the length of A′C′?
11 units
61 units
90 units
60 units

Answers

Answer:

60 Units

Step-by-step explanation:

The length of AC does not change. Since the translation is a rotation, nothing about the size of the triangle should change. Meaning A'B'C' is still 60 units in length.

The length of the side A'C' of the triangle after rotation is A'C' =AC = 60 units

What is Rotation?

The measure of the amount a figure is rotated about the center of rotation is called the angle of rotation. The angle of rotation is usually measured in degrees. We specify the degree measure and direction of a rotation.

90° clockwise rotation: (x,y) becomes (y,-x)

90° counterclockwise rotation: (x,y) becomes (-y,x)

180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)

270° clockwise rotation: (x,y) becomes (-y,x)

270° counterclockwise rotation: (x,y) becomes (y,-x)

Given data ,

Let the triangle be represented as ΔABC

Now , the measures of the sides of the triangle are

The measure of side AB = 61 units

The measure of side BC = 11 units

The measure of side AC = 60 units

And , the triangle is rotated by 90° counterclockwise  about the origin

The coordinates of the triangle after rotation is A'B'C'

And ,

The measure of side A'B' = 61 units

The measure of side B'C' = 11 units

The measure of side A'C' = 60 units

The length of the sides of the triangle does not change during a transformation of rotation by any degree

Hence , the measure of side A'C' of triangle is 60 units

Ana,beto y Carla son confeccionará de polos,por cada 12 polos que confecciona Ana,Beto confecciona 7,mientras que por cada 28 polos que confecciona Beto,Carla confecciona 15 si el fin de semana Carla confecciona 198 polos más que Carla,cuántos polos confecciono Beto ese día?

Answers

Resolviendo un sistema de ecuaciones veremos que polo hizo 170 polos.

¿Cuantos polos confecciono Beto ese día?

Sabemos que por cada 12 polos que confecciona Ana, Beto hace 7.

Por cada 28 polos que confecciona Beto, Carla confecciona 15.

Y sabemos que Ana hizo 198 polos mas que Carla.

Definamos las variables:

C = polos que hizo Carla.

A = polos que hizo Ana

B = polos que hizo Beto.

Podemos escribir las ecuaciones:

A = C + 198

B = (7/19)*A

B = 28/(28 + 15)*C

Tenemos un sistema de ecuaciones, las segundas dos son las que obtenemos con los ratios que nos proporcionan.

Reemplazando la primer ecuacion en la segunda obtenemos el sistema:

B = (7/19)*(C + 198)

B = 28/(43)*C

De la segunda ecuacion podemos obtener:

C = B*(43/28)

Remplazando eso en la otra ecuacion obtenemos:

B = (7/19)*(B*(43/28)+ 198)

Ahora podemos encontrar el valor de B.

B = 0.57*B + 72.95

B - 0.57*B =  72.95

B*0.43 = 72.95

B = 72.95/0.43 = 169.6

Redondenado, B = 170, ese es el número de polos que Beto confecciono.

Trig identity are written in term of cosine, sine and tangent, he value of cosθ if the value of sinθ is 9/41 is 40/41

Trigonometry ratio

Given the following parameters

sinθ = 9/41

According to the SOH CAH TOA identity

sinθ = opposite/hypotenuse

Determine the adjacent sides

a= √41² - 9²

a = √ 1600

a = 40

Determine the value of cosθ

cosθ = adjacent/hypotenuse

cosθ = 40/41

Hence the value of cosθ if the value of sinθ is 9/41 is 40/41

Angle P and angle Q are supplementary angles. If m(angle)p is 21 degrees less than twice the measure of
Angle Q , find the measure of each angle.

Answers

Answer:

Angle Q: 67 degrees

Angle P: 113 degrees

Step-by-step explanation:

You can write an equation to solve this. We know that angle P + angle Q = 180. If we substitute angle Q into the second equation we get angle P = 2*angle Q -21.

Plugging that knowledge into the first equation, we get 2*angle Q-21 + angle Q =180. Simplifying, we get 3* angle Q -21 = 180. Adding 21 to both sides gives us 3*angle Q = 201, dividing by 3 gives us angle Q = 67. 180-67= 113 so angle P is 113.
