Answer:

(A)1/3

Step-by-step explanation:

probability of getting a 2 = 1/6

probability of getting a 6 = 1/6

so the probability of getting a 2 or a 6

=(probability of getting a 2+probability of getting a 6)

=(1/6+1/6)

=2*(1/6)

=1/3

Step-by-step explanation:

Answer:

a) 24 degrees

b) 50 degrees

Step-by-step explanation:

part a : use sine-1

sine-1 = [tex]\frac{opposite}{hypotenuse}[/tex]

sine-1 = [tex]\frac{17}{42}[/tex]

sine-1 = 0.405

missing angle = 23.89

round to the nearest degree = 23.89 = 24

part b : use cosine-1

cos-1 = [tex]\frac{adjacent}{hypotenuse}[/tex]

cos-1 = [tex]\frac{16}{25}[/tex]

cos-1 = 0.64

missing angle = 50.208

round to the nearest degree = 50.208 = 50

Answer:

y=9x

Step-by-step explanation:

First let's find the slope of this.

To find the slop we can take two points.

(1,9) & (3,27)

27-9/ 3-1 (slope equation) = 18/2=9

The slope of the equation is 9.

Now let's use point-slope form to find the equation.

(1,9)

y-9=m(x-1) (substitute the x2 and y2 values for the coordinate values)

y-9=9(x-1) (substitute m for the slope)

y=9x-9+9

y=9x

Answer:

The exponential model is [tex]y = 0.07\cdot e^{0.73\cdot x}[/tex].

Step-by-step explanation:

The exponential model can be modelled by the following mathematical expression:

[tex]y = A\cdot e^{B\cdot x}[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

[tex]A, B[/tex] - Coefficients.

If we know that [tex](x_{1}, y_{1}) = (7,12)[/tex] and [tex](x_{2}, y_{2}) = (8,25)[/tex], then we get the following system of equations:

[tex]A\cdot e^{7\cdot B} = 12[/tex] (2)

[tex]A\cdot e^{8\cdot B} = 25[/tex] (3)

If we divide (3) by (2), we calculate the value of [tex]B[/tex]:

[tex]e^{B}=\frac{25}{12}[/tex]

[tex]B = \ln \frac{25}{12}[/tex]

[tex]B \approx 0.734[/tex]

And by (2), we determine the value of [tex]A[/tex]:

[tex]A = 12\cdot e^{-7\cdot B}[/tex]

[tex]A = 0.0704[/tex]

The exponential model is [tex]y = 0.07\cdot e^{0.73\cdot x}[/tex].

Sure Amaya  , the grouping is the parenthesis, right?

Step-by-step explanation:

so  just add up.. the things outside of the parenthesis

-  [tex]4^{2}[/tex] * 4

so exponents come first in the order of what to do... right?

[tex]4^{2}[/tex] =16    okay , got that part, the next part is

16 * 4 = 64   okay got that part,  now

Answer:

x = 25

Step-by-step explanation:

2x + 70 = 120      {Subtract 70 from both sides}

        2x = 120 -70

        2x = 50      {divide both sides by 2}

          x = 50/2

20)452.39ft²

Step-by-step explanation:

Step-by-step explanation:

To find the diameter of a circle, you multiply the radius (the radius is the distance from the outside of the circle to the middle) by 2.

Ex: the first one has 6m as the radius. So you would multiply the 6 by 2. Which would be 12.

The radius is half of the diameter. So for number 8, the answer would be 2.

hope this helps and that it wasn't to confusing  :)

Answer:

C

Step-by-step explanation:

The length of arc AC (L) is calculated as

L = circumference of circle × fraction of circle

Answer:

There were 206 more people on Thursday than on Monday.

Step-by-step explanation:

520 - 314 = 206

Answer:

C = 101

E = 46

Step-by-step explanation:

79 + 134 = 213

180 - 79 = 101 (C+F has to equal 180)

79 + 134 + 101 = 314

360 - 314 = 49 (trapezoids have a total degree of 360)

The measure of angles are ∠C = 101°, ∠E = 46°, ∠J = 83°, ∠L =97°, and ∠M = 97°.

It is given in the picture that measures the angles of a trapezoid.

It is required to find the other angles.

It is defined as the quadrilateral having four sides in which two sides are parallel to each other it is a 2-dimensional geometry.

We have a trapezoid CDEF in which ∠D = 134° and ∠CFE = 79°

We know in trapezoid:

∠C+∠F = 180° and

∠D+∠E = 180°

For ∠C = 180° - ∠F ⇒ 180° - 79° ⇒ 101°

For ∠E = 180° - ∠E  ⇒ 180° - 134° ⇒46°

We have another trapezoid JKLM in which ∠K = 83°

We know in isosceles trpezoid:

∠K = ∠J = 83° and

∠L = ∠M

∠L = 180° - ∠K ⇒ 180° - 83°  ⇒ 97° ⇒ ∠M

Thus, the measure of angles are ∠C = 101°, ∠E = 46°, ∠J = 83°, ∠L =97°, and ∠M = 97°.
