Answer:

53 and 118

Step-by-step explanation:

Just know that all the angles in a triangle add up to 180 degrees. In the first one, you can tell it is a right triangle by the square in the corner and the other angle is 37. So 180-(37+90)=53

For the second one, it is the same case so 180-(42+20)= 118

Answer:

53 degrees

Step-by-step explanation:

sum of angles in a triangle is 180

a right angle is 90

missing angle is B

180 = 90 + 37 + B

180 = 127 + B

B = 53

Answer: 2

Step-by-step explanation:

Change the divisor 4.5 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.

We then have the equations:

90 ÷ 45 = 2

and therefore:

9 ÷ 4.5 = 2

Answer:

A. The data show a negative linear relationship.

Step-by-step explanation:

According to the attached image as we can see that the temperature is in Y axis and volume of ice cubes is in X axis

So the following statements considered to be true

a. The volume represents the explanatory variable

b. Temperature would be strongly correlated to the ice cubes volume

c. As the correlation coefficient is near to -1

But it does not show the negative linear relationship

Therefore the correct option is a.

Answer:

y=3x-5

Step-by-step explanation:

so step by step would go like this

Point A Before: ( 1 , 3 )

1 - 4 = -3

3 - 2 = 1

( -3 , 1 )

hope this helps

y = -9

Ok so to write the equation of the line you will need the slope and y-intercept. Since we are given two-point we can easily find the slope by using this equation for slope formula:

[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

So now that we have our equation we can just plug in the numbers:

[tex]\frac{(-9)-(-9)}{5-(-3)}[/tex]

After subtracting you should get:

0/8

Since zero is in the numerator and you can't divide zero by anything, the slope is 0. We still need the y-intercept for the equation however since the slope is 0 there is no need to put anything else.

Then to find the y-intercept all you have to do is plug in one of the coordinatines into the slope equation to solve, for example, using the point (5,-9):

[tex](-9) = 5(0) + b[/tex]

B is the variable for the y-intercept. Also notice how I put 0 as our slope into the equation. Now all you have to do is solve for b. Which you would get b = -9. Since you have your slope and your y-intercept now you just write out your equatoin for the line which is:

y = 0x - 9

**Just write it as

y = -9

Answer:

Y = -9

Answer:

1st and 4th are the right triangles

Question is not complete, so i have attached it.

Answer:

B: -2x² - 6x² - 6x + 3x + 3 + 2

Step-by-step explanation:

From the image attached, the given polynomial is;

3 - 6x - 2x² + 3x - 6x² + 2

For like terms to be next to each other, we have to rearrange it as follows;

-2x² - 6x² - 6x + 3x + 3 + 2

Like terms are x² and x, thus they are now arranged next to each other.

The only option that corresponds to our answer is option B

Step-by-step explanation:

doesn't mean I'm right though.

Answer:

2nd option

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- [tex]\frac{3}{2}[/tex], 0) and (x₂, y₂ ) = (0, [tex]\frac{3}{4}[/tex] )

m = [tex]\frac{\frac{3}{4}-0 }{0+\frac{3}{2} }[/tex] = [tex]\frac{\frac{3}{4} }{\frac{3}{2} }[/tex] = [tex]\frac{1}{2}[/tex] and c = [tex]\frac{3}{4}[/tex] , then

y = [tex]\frac{1}{2}[/tex] x + [tex]\frac{3}{4}[/tex] ( multiply through  by 4 to clear the fractions )

4y = 2x + 3 ( subtract 4y from both sides )

0 = 2x - 4y + 3 , that is

2x - 4y + 3 = 0 ← equation of line

Answer:

No

Step-by-step explanation:

1. (270 * 3) + (650 * 1)

2. 810 + 650

3. 1,460 miles. Therefore, by doing this, Mark would have trekked 1,460 miles.

4. 1500 > 1460, so Mark would not meet his goal by doing this.

Answer:

Step-by-step explanation:

Sum of exterior angles of any polygon =360°

Sum of exterior angles of polygon = 360°

m + 5  + 2m + 3 + 3m + 2 + 4m + 1 + 5m + 4 = 360

m + 2m + 3m + 4m + 5m + 5 + 3 + 2 + 1 + 4  = 360  {Combine like terms}

15m + 15 = 360 {Subtract 15 from both sides}

        15m = 360 - 15

        15m = 345 {Divide both sides by 15}

           m = 345/15

m = 23

m + 5 = 23 + 5 = 28°

2m + 3 = 2*23 + 3 = 46 + 3 = 49°

3m + 2 = 3*23 + 2 = 69 + 2 = 71°

4m + 1 = 4*23 + 1 = 92 + 1 = 93°

5m + 4 = 5*23 + 4 = 115 + 4 = 119°

Answer:

see explanation

Step-by-step explanation:

The sum of the exterior angles of a polygon = 360°

Sum the angles and equate to 360

m + 5 + 2m + 3 + 3m + 2 + 4m + 1 + 5m + 4 = 360, that is

15m + 15 = 360 ( subtract 15 from both sides )

15m = 345 ( divide both sides by 15 )

m = 23

Then

m + 5 = 23 + 5 = 28°

2m + 3 = 2(23) + 3 = 46 + 3 = 49°

3m + 2 = 3(23) + 2 = 69 + 2 = 71°

4m + 1 = 4(23) + 1 = 92 + 1 = 93°

5m + 4 = 5(23) + 4 = 115 + 4 = 119°

3. 3 “PRUEBA DE HIPÓTESIS” INTRODUCCIÓN Es evidente que las distribuciones muestrales, vistas en el capítulo anterior, basadas en la teoría de la distribución normal, desarrollan un papel de gran importancia en la inferencia estadística. La inferencia estadística comprende dos partes principales, a saber: la estimación de parámetros y la prueba o docimasia de hipótesis. En este capítulo estudiaremos la segunda de ellas, con el fin de desarrollar métodos y observar su aplicación a problemas corrientes de la vida diaria. La inferencia estadística está basada en el supuesto de tomar muchas muestras, todas con igual probabilidad de ser seleccionadas y a través de una de ellas sabremos algo acerca de la población, mediante el cálculo de estimadores, que nos permitan hacer aseveraciones, incorrectas algunas veces, estableciéndose la probabilidad de error. Este método se basa en la aplicación de técnicas de muestreo, para lo cual se requiere de un buen diseño, además de la aplicación de métodos aleatorios de selección, cuando las probabilidades son iguales para cada elemento de una población. En algunos casos no requieren ser iguales, siempre que se conozcan y sean diferentes a cero.

Need a pic to answer your question

Answer:

New cost of jacket = [tex]1.2x=1.2\times 600=720\ \text{sh}[/tex]

New costs of skirt = [tex]1.2y=1.2\times 200=240\ \text{sh}[/tex]

Step-by-step explanation:

Let original cost of jacket = [tex]x[/tex]

original cost of skirt = [tex]y[/tex]

The equation will be

[tex]2x+3y=1800[/tex]

New cost of jacket = [tex]1.2x[/tex]

New costs of skirt = [tex]1.2y[/tex]

The equation will be

[tex]6(1.2x)+2(1.2y)=4800\\\Rightarrow 7.2x+2.4y=4800[/tex]

The equations are

[tex]2x+3y=1800[/tex]  [tex]\times 0.8[/tex]

[tex]7.2x+2.4y=4800[/tex]

[tex]1.6x+2.4y=1440[/tex]

[tex]7.2x+2.4y=4800[/tex]

Subtracting the above two equations we get

[tex]-5.6x=-3360\\\Rightarrow x=\dfrac{3360}{5.6}\\\Rightarrow x=600[/tex]

[tex]7.2\times 600+2.4y=4800\\\Rightarrow y=\dfrac{4800-7.2\times 600}{2.4}\\\Rightarrow y=200[/tex]

New cost of jacket = [tex]1.2x=1.2\times 600=720\ \text{sh}[/tex]

New costs of skirt = [tex]1.2y=1.2\times 200=240\ \text{sh}[/tex].
