help me please :( ill give u brainnlyyyyyyy :DDD

Answer:

The value of x in this equation is 8.

Step-by-step explanation:

5x - 1 = 6x - 9

Subtract 6x on both sides.

-x - 1 = -9

Add 1 to both sides.

-x = -8

Divide by -1 on both sides.

x = 8

Explicación paso a paso:

Dados los datos: 55, 51, 60, 56, 64, 56, 63, 63, 61, 57, 62, 50, 49, 70, 72, 54, 48, 53, 58, 66, 68, 45, 74, 65, 58, 61, 62, 59, 64, 57, 63, xx, xx

Los dos valores faltantes podrían ingresarse utilizando varios métodos, incluyendo la mediana, modal y el valor medio de los datos dados en la distribución.

Aquí usaremos el valor medio.

Media (m) de los datos = suma de la observación / número de observaciones Media =

(55 + 51 + 60 + 56 + 64 + 56 + 63 + 63 + 61 + 57 + 62 + 50 + 49 + 70 + 72 + 54 + 48 + 53 + 58 + 66 + 68 + 45 + 74 + 65 + 58 + 61 + 62 + 59 + 64 + 57 + 63) / 31 = 1844/31 = 59.4 = 59 (al número entero más cercano) Entonces reemplace los valores faltantes con 59.

En otro para hacer cálculos sobre los datos, hay que reorganizarlos.

Datos ordenados: 45,48,49,50,51,53,54,55,56,56,57,57,58,58,59,59,59,60,61,61,62,62,63,63,63, 64,64,65,66,68,70,72,74

Los cuartiles de datos:

Primer cuartil (Q1) = 1/4 (33 + 1) = 1/4 (34) = 8.5

Q1 = (8º + 9º) / 2 = (55 + 56) = 111/2 = 55,5

Segundo cuartil (Q2) = Q3 - Q1 = (25.5 - 8.5) = 17th = 59

Tercer cuartil (Q3) = 3/4 (33 + 1) = 3/4 (34) = 25.5 Q3 = (25 + 26) = (63 + 64) = 127/2 = 63.5

Rango intercuartil (IQR) = 63.5 - 55.5 = 8

Mediana = Q2 = 59

Mínimo = 45

Máximo = 74

Rango = 74-45 = 29

El quinto decil:

D5 = [5 (33 +1)] / 10 = 5 (34) / 10

D5 = 170/10 = 17º valor = 59

7mo decil: D7 = [7 (33 + 1)] / 10 = 7 (34) / 10

D7 = 238/10 = 23.8 ° término D7 = 63

Percentil:

Percentil 13 (13% × 33) = 0.13 × 33 = 4.29

4to término = 50

Percentil 76: (76% × 33) = 0.76 × 33 = 25.08

25 ° término = 63

Answer:

Volume = 240 feet³

Step-by-step explanation:

We'll find it's volume

Volume = [tex]Lenth *Width*Height[/tex]

Where Length = 4, Width = 6, Height = 10

Volume = 4 * 6 * 10

Volume = 240 feet³

i am not so sure

Answer:

x = 12.5

Step-by-step explanation:

Since measure of 4th arc is not given (measure of 3 arcs have been given), we will apply the following theorem.

By the intersecting chords theorem,

"If two chords intersecting inside a circle, measure of the angle between these chords will measure the half the sum of measures of arcs intercepted by the angle and its vertical angle."

Here intercepted arcs are (2x)° and 155°. Angel between the chords measure 90°.

By the theorem,

90° = [tex]\frac{1}{2}(2x + 155)[/tex]°

180° = (2x + 155)°

2x = 180 - 155

2x = 25

x = 12.5

Answer:

so turn it into the other form:

2x+4y=-8

4y=-2x-8

y=-0.5-2

then:

a) y=-0.5x+44

b) y=-0.5x-2 (itself)

c) y=-55x-2 (they cut each other in (0,-2)

Answer:

nonlinear

Step-by-step explanation:

The word 'linear' means something having to do with a line. On a Cartesian Plane, a linear characteristic is a feature wherein the graph is a straight line. The line can cross in any direction, but it's always an instant line. A non-linear function has a shape that isn't an immediate line

The graph is nonlinear because it is not a straight line.

please mark me brainliest!

Answer:

Nonlinear.

Step-by-step explanation:

Since x is being squared, the equation is actually a parabola. The power of x has to be 1 for the function to be a linear function, so this equation is nonlinear.

Answer:

D = 9.80

Step-by-step explanation:

To find AB, we'll use the distance formula:

Distance Formula = [tex]\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]

D = [tex]\sqrt{(10-1)^2+(3-7)^2}[/tex]

D = [tex]\sqrt{(9)^2+(-4)^2}[/tex]

D = [tex]\sqrt{81+16}[/tex]

D = [tex]\sqrt{96}[/tex]

D = 9.80 (Upto 3 sfs)

Answer: The height is 6 meters

Step-by-step explanation:

3 * 2 *h = 36   where h is the height

6h = 36

h = 6

Answer:

The answer is 6

Step-by-step explanation:

Because you would have to get 6h=36 alone so you would have to divide 6 by both sides. which gives you h=6

Option 2) [tex]x^{\frac{1}{8}}y^8[/tex]

Step-by-step explanation:

=> [tex](x^{\frac{1}{4} } y ^{16} )^\frac{1}{2}[/tex]

=> [tex]x^{\frac{1}{4} * \frac{1}{2} } * y ^{16*\frac{1}{2} }[/tex]

=> [tex]x^{\frac{1}{8}}y^8[/tex]

Answer:

y - 1 = 0.

Step-by-step explanation:

First off, we need to find the slope between the two points. That would be (1 - 1) / (2 - -2) = 0 / 4 = 0.

So, we would have an equation y = mx + b, where m is the slope and b is the y-intercept. Since the slope is 0, we have y = 0x + b, or y = b.

If you examine the coordinates, y always equals 1. So, b = 1, and y = 1.

y = 1

y - 1 = 0.

Answer:

P(meet) = 55/64

P(meet) = 0.8594

P(meet) = 85.94%

Therefore, there is a 85.94% probability that Annie and Xenas see each other at the party.

Step-by-step explanation:

Let A denote Annie and X denotes Xenas.

The total time is 2 hours (2:00 to 4:00)

Both A and X stays for 45 minutes or 3/4 hours

The probability that A and X do not meet is given by

P(Not meet) = (3/4)/2 × (3/4)/2

P(Not meet) = 9/64

So the probability that A and X will meet is given by

P(meet) = 1 - P(Not meet)

P(meet) = 1 - 9/64

P(meet) = 55/64

P(meet) = 0.8594

P(meet) = 85.94%

Therefore, there is a 85.94% probability that Annie and Xenas see each other at the party.

Answer:

the slope is 5

Step-by-step explanation:

y = 5 x – 3

This equation is in slope intercept form

y = mx+b where m is the slope and b is the y intercept

the slope is 5 and the y intercept is -3

Answer:

The Slope is 5

Step-by-step explanation:

As seen in the y-intercept equation, 5x is shown as the slope of the line.

Answer:

0.75 or 3/4

Step-by-step explanation:

If we call the common ratio r, since 4 - 1 = 3 we can write:

64 * r³ = 27

r³ = 27/64

r = ∛(27/64) = ∛27 / ∛64 = 3 / 4

Answer:

(a) the common ratio = 3/4.

Step-by-step explanation:

First term a1 = 64

The fourth term a4 = a1 r^3 = 27

So a1 r^3 / a1 = 27/64

r^3 =  (27/64)

r = ∛ (27/64

= 3/4.

Answer:

The measurement for x is 80°

Step-by-step explanation:

In the picture, we see two parallel lines cut by a transversal line. Since the lines are cut by a transversal, then there are a few things we should know that can help us find the value of x.

Now that we know these things, we can use this information to find the measurement of ∠CBA. We do this by subtracting 100 from 180 because ∠CBA and ∠CBD are a linear pair. Once we know the measurement of this angle, then it will be much easier to find the value of x.

180 - 100 = 80

So, the measurement of ∠CBA is 80°. Now, ∠CBA and ∠x are corresponding angles so this means that they have the same measurements. If the measurement of ∠CBA is 80°, then the measurement of ∠x is also 80°

x = 80°

Answer:

f(x) = |x + 4| + 2.

Step-by-step explanation:

When you shift the function to the left, the x-value changes, so you put the change within the absolute value. Also, within the absolute value, when you shift things to the right, you minus, and when you shift to the left, you add.

When you shift the function up, the y-value changes, so you put the changes outside of the absolute value. Shifting up means adding and shifting down means subtracting.

Answer:

  no

Step-by-step explanation:

In ∆XYZ, we can write the ratios of the sides from shortest to longest as ...

  y : z : x = 1 : 1.5 : 2 = 2 : 3 : 4

In ∆QSR, we can write the ratios of the side lengths from shortest to longest as ...

  r : s : q = 0.5 : 1 : 1.5 = 1 : 2 : 3

Based on side lengths only, the triangles cannot be similar.

__

Additional note

Even if shortest-to-longest side ratios were the same, the triangle naming is incorrect for them to be similar.
