Answer:

[tex]Pr = \frac{1}{2}[/tex]

Step-by-step explanation:

Given

[tex]S = \{1,2,3,4,5,6\}[/tex] --- the faces of the dice

[tex]n(S) = 6[/tex]

Required

Pr(Multiple of 8)

The multiples of 8 in the given dataset are:

[tex]Multiples = \{1.,2,4\}[/tex]

[tex]n(Multiples) = 3[/tex]

So, we have:

[tex]Pr = \frac{n(Multiples)}{n(S)}[/tex]

[tex]Pr = \frac{3}{6}[/tex]

Simplify

[tex]Pr = \frac{1}{2}[/tex]

Answer:

D. 23/27

Step-by-step explanation:

The good news is, they wrote out all the possible options for you.

There are 27 possibilities in all, so that's our denominator.

They want to know which possibilities have a W in there OR an R comes first. So we'll count up the possibilities that start with R. There are 9.

Then, of the remaining 18, 14 include a W somewhere in there.

9 + 14 = 23 out of 27.

We are not counting the Ws in the possibilities that start with R, because of the OR in the sentence.

Please let me know if you have questions about this.

Answer:

203.5 units

Step-by-step explanation:

The equation to find the area of a triangle is:-

[tex]\frac{1}{2}[/tex] x base x height

The base of this triangle is 37 units and its height is 11 units.

Substituting these values in the equation, we get:-

[tex]\frac{1}{2}[/tex] x 37 x 11

[tex]\frac{1}{2}[/tex] x 407

[tex]\frac{407}{2}[/tex]

Area equals 203.5 units.

Answer:

203 1/2 or 203.5

Step-by-step explanation:

we know that a area of a triangle is base x height divided by 2. So we multiply the value of the base than the height of the unit of the base which contains 37x11 and then divide by 2 to get the inside of the triangle unit.

Answer:

C: 7.0

Step-by-step explanation:

We are told that; 0|5| means 50 and that |4|8 means 48. Thus;

Temperatures for baker city are;

49, 46, 43, 55, 53, 50, 61

Temperatures for felina are;

48, 54, 54, 58, 62, 63, 67

Thus;

Mean temperature of baker city = (49 + 46 + 43 + 55 + 53 + 50 + 61)/7 = 51°F

Mean temperature of Felina = (48 + 54 + 54 + 58 + 62 + 63 + 67)/7 = 58°F

Thus, difference between the 2 mean = 58°F - 51°F = 7.0°F

Given:

The equation of parallel line is:

[tex]3x-2y=5[/tex]

The required line passing through the midpoint of the line segment joining the points (-4,2) and (2,4).​

To find:

The equation of required line.

Solution:

Midpoint of  line segment joining the points (-4,2) and (2,4) is:

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-4+2}{2},\dfrac{2+4}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-2}{2},\dfrac{6}{2}\right)[/tex]

[tex]Midpoint=\left(-1,3\right)[/tex]

It means the required line passes through the point (-1,3).

The slope of line [tex]Ax+By=C[/tex] is:

[tex]m=\dfrac{-A}{B}[/tex]

The given equation is:

[tex]3x-2y=5[/tex]

Here, A=3 and B=-2. So, the slope of the line is:

[tex]m=\dfrac{-3}{-2}[/tex]

[tex]m=1.5[/tex]

Slope of parallel lines are same. So, the slope of the required line is 1.5.

The required line passes through the point (-1,3) with slope 1.5. So, the equation of the line is:

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-3=1.5(x-(-1))[/tex]

[tex]y-3=1.5(x+1)[/tex]

[tex]y-3=1.5x+1.5[/tex]

Adding 3 on both sides, we get

[tex]y=1.5x+1.5+3[/tex]

[tex]y=1.5x+4.5[/tex]

Therefore, the equation of the required line is [tex]y=1.5x+4.5[/tex].

Answer:

12

Step-by-step explanation:

A 2 - sided counter ; (red, yellow)

A spinner (1,2,3,4,5,6)

Number of trials = 80

P(red and number > 3) :

P(red) = 1/2 ;

P(number >3) : numbers greater Than 3 = (4, 5, 6)

Hence, P(number <3) = 3 /6 = 1/2

Theoretical probability = 1/2 *1/2 = 1/4

Expected number of outcomes :

1/4 * number of trials

1/4 * 80 = 20

Experimental outcome :

Relative frequency = number of outcomes / number of trials

Relative frequency = 2/5

Hence,

2/5 = number of outcomes / 80

Cross multiply :

160 = number of outcomes * 5

Number of outcomes = 160 /5 = 32

Actual outcomes = 32

Difference between actual and expected :

32 - 20 = 12

Answer:

A. Adding the values of the intercepted arcs and that is equal to twice the angle measure

Step-by-step explanation:

The intersecting chords theorem states that when four line segments are formed by two chords intersecting in a circle, the product of the two line segments on one chord is equal to the product of the two line segments on the other chord

The angles of intersecting chords theorem states that the angles formed by the intersecting chords one half the sum of the arcs intercepted by the chords

In the diagram attached, we have;

∠x = ∠y + ∠z

m[tex]\widehat{DHE}[/tex] = 2·∠z, m[tex]\widehat{CIF}[/tex] = 2·∠y

∴ ∠x = (1/2) × m[tex]\widehat{DHE}[/tex] + m[tex]\widehat{CIF}[/tex]

m[tex]\widehat{DHE}[/tex] + m[tex]\widehat{CIF}[/tex] = 2 × ∠x

The correct option is therefore adding the values of the intercepted arcs and that is equal to twice the angle measure.

9.5

Step-by-step explanation:

Recall that: D/2 = r

Therefore 120cm÷2 = 60cm

35m÷2 = 27.5m

19km÷2 = 9.5km

Step-by-step explanation:

V = l.W.H

3(5)(4) = 60 units

The volume of rectangular prism is given by the product of its dimensions hence the correct option is 3(5)(4) = 60 units

A volume is simply defined as the amount of space occupied by any three-dimensional solid. These solids can be a cube, a cuboid, a cone, a cylinder or a sphere. Different shapes have different volumes.

Given that, we need to determine the correct calculation for the volume of the prism,

We know that, the volume of a rectangular prism is the  product of its dimensions = length x width x height

Therefore, the correct formula is 3(5)(4) = 60 units

Hence, the correct option is 3(5)(4) = 60 units

Answer:

Reflected across x-axis followed by a dilation with a scale factor of 2 about the origin.

Step-by-step explanation:

It's clear from the graph,

Polygon ABCDE is reflected across x-axis then dilated so that it overlaps polygon A'B'C'D'E'

Let's choose a point A having coordinates (-2, -1)

By reflecting point A across x-axis,

Rule to be followed for the reflection,

(x, y) → (x, -y)

By this rule, coordinates of the image point A will be,

A(-2, -1) → A"(-2, 1)

Now point A"(-2, 1) has been dilated by a scale factor = k to form an image points A'(-4, 2).

Rule for the dilation of a point about the origin is,

A"(x, y) → A'(kx, ky)

A"(-2, 1) → A'(-2k, k)

Since, coordinates of point A' are (-4, -2),

Therefore, -2k = -4

k = 2

k = 2

Hence, polygon ABCDE was reflected across x-axis followed by a dilation with a scale factor of 2 about the origin to form polygon A'B'C'D'E'.

Answer:

1523905

Step-by-step explanation:

Given the function

P(t) = P0 * 2^t/d

P0 = 15000 ; d = 3.; t = 20

P(20) = 15000 * 2^20/3

P(20) = 15000 * 2^6.66666

P(20) = 15000 * 101.59366

P(20) = 1523905.0

P(20) = 1523905

Answer:

x = 31°

Step-by-step explanation:

All the angles given, a, 2x, and 3x, form a straight lines, so therefore, they add up to 180°. We can write an equation from the info:

a + 2x + 3x = 180°

We know a is 25°, so we can substitute that in:

25° + 2x + 3x = 180°

Combine like terms...

25° + 5x = 180°

And solve.

5x = 155°

x = 31°

Answer:

M<2= 95° M<3=85° M<4=95°

Step-by-step explanation:

Remember that the angles could be either supplementary or congruent angles so since angle 2 and 1 are supplemental take 85 and subtract it from 180. So 2 =95 Now the congruent angle for angle 2 is 4 so 4=95. Applying the same property angle 1 is congruent to 3 so 3=85

Hope this helps!

Answer:

∠2 = 95°

∠3 = 85°

∠4 = 95°

Step-by-step explanation:

∠85° and ∠3 are vertical angles therefore they are equal to each so we know that ∠3 = 85°.

In order to find ∠2, we need to notice that ∠85° and ∠2 are supplementary angles (this means that they add up to 180°). So now we can make an equation...

∠2 = 180° - 85°

∠2 = 95°

To find ∠4 we use the same logic as for ∠2 and we get that ∠4 = 95°

Answer:

  a)  P = -28(x -112)² +7500

  b) $102.55 or $121.45

Step-by-step explanation:

a) A quadratic relation with a maximum of 7500 at x=112 can be written in vertex form as ...

  P = a(x -112)² +7500

The other given point (x, P) = (89, -7312) can be used to find the value of 'a'.

  -7312 = a(89 -112)² +7500

  -14812 = a(529)

  a = -14812/529 = -28

So, the desired quadratic relation is ...

  P = -28(x -112)² +7500

__

b) The values of x that make P = 5000 can be found from ...

  5000 = -28(x -112)² +7500

  -2500 = -28(x -112)² . . . . . . . . subtract 7500

  89.286 = (x -112)² . . . . . . . . . . . divide by -28

  ±9.45 = x -112 . . . . . . . . . . take the square root

  x = 112 ± 9.45 = {102.55, 121.45}

Setting the price at about $102.55, or $121.45, will yield a profit of $5000.
