In theory, yes. Light that left the earth 65 million years ago is now 65 million light years away, and an alien with a big enough telescope pointed directly at the earth might be able to see dinosaurs. Practically, such a telescope would be impossibly huge.

Answer:

Hmm, rather unusual question. I think that if an alien were looking at Earth 100,000 light years away, I don't think it would be able to see Earth! But if it could, it would see a planet filled with life, buildings, water and land.

Answer:

Yes, because the sum of all of the probabilities is 1.

Step-by-step explanation:

The given probability equation is:

[tex]P(x)=\frac{2x-1}{16}[/tex], where x belongs to {1,2,3,4}.

[tex]P(1)=\frac{2(1)-1}{16}=\frac{1}{16}[/tex]

[tex]P(2)=\frac{2(2)-1}{16}=\frac{3}{16}[/tex]

[tex]P(3)=\frac{2(3)-1}{16}=\frac{5}{16}[/tex]

[tex]P(4)=\frac{2(4)-1}{16}=\frac{7}{16}[/tex]

Let us sum all the probabilities to obtain;

[tex]P(1)+P(2)+P(3)+P(4)=\frac{1}{16}+ \frac{3}{16}+\frac{5}{16}+\frac{7}{16}[/tex]

[tex]P(1)+P(2)+P(3)+P(4)=\frac{1+3+5+7}{16}[/tex]

[tex]P(1)+P(2)+P(3)+P(4)=\frac{16}{16}[/tex]

[tex]P(1)+P(2)+P(3)+P(4)=1[/tex]

Since the sum of all the probabilities is 1, it is a probability distribution

Answer:

6.37%

Step-by-step explanation:

A deck of cards have 52 cards.  There are 4 suits of 13 card each, those suits are Hearts, Clubs, Diamond and Spades.

The probability that the first card is a heart is:

[tex]P(Hearts) = \frac{13}{52}[/tex]

Now, the probabily that the second card is a diamond is:

[tex] P(Diamond | First card is Heart) = \frac{13}{51}[/tex]

The Probability that the first card is a heart and the second one a diamond is given by:

[tex]P(Hearts)[/tex]×[tex]P(Diamond | First card is Heart)[/tex]

[tex]= \frac{13}{52}\frac{13}{51}[/tex]

[tex]= 6.37[/tex]%

Answer:

6.37 %

Step-by-step explanation:

First card is 13/52 , the second card is 13/51.

So the probability is (13/52 × 13/51) = 6.37 %

Answer:

c = - 2, c = 7

Step-by-step explanation:

Given

c² - 14 = 5c ( subtract 5c from both sides )

c² - 5c - 14 = 0 ← in standard form

To factorise the quadratic

Consider the factors of the constant term (- 14) which sum to give the coefficient of the c- term (- 5)

The factors are - 7 and + 2, since

- 7 × 2 = - 14 and - 7 + 2 = - 5, hence

(c - 7)(c + 2) = 0

Equate each factor to zero and solve for c

c - 7 = 0 ⇒ c = 7

c + 2 = 0 ⇒ c = - 2

Answer:

The correct answer is   104.55

Step-by-step explanation:

From the given information we can write,

Principle amount = 100

To find the amount after 10 years in plan A

Now total = 100

Under plan A increase his account balance by 20.00 per year

Amount increased = 10 *20 = 200

Total = 100 + 200 = 300

To find the amount after 10 years in plan B

Total = 100

Amount after 10 yeras = 100[1 + 15/100]¹⁰

= 100 * 1.15¹⁰ = 100 * 4.04 = 404.55

To find the difference

Difference = 404.55 - 300

= 104.55

The correct answer is   104.55

Answer:

112.81 m.

Step-by-step explanation:

The pole and the tower and their shadows form 2 similar triangles so their corresponding sides are in the smae ratio.

Therefore we have the relation:

1.21 / 48.75 = 2.8 / x   where x is the height of the tower.

Cross multiplying:

x = 2.8 * 48.75 / 1.21

= 112.81 m

Final answer:

To find the height of the tower, we use the proportion 2.8 m / 1.21 m = H / 48.75 m. After cross-multiplication and division, the height of the tower is calculated to be approximately 112.81 meters.

Explanation:

The student's question involves using similar triangles to determine the height of a tower based on the shadow it casts. To solve this problem, we can set up a proportion because the pole and tower will cast shadows at the same angle due to the sun's position. The proportional relationship is formed by the height of the pole over its shadow length being equal to the height of the tower over its shadow length.

Let's designate the height of the tower as H. The proportion will then be:

2.8 m / 1.21 m = H / 48.75 m

Cross-multiplying to solve for H, we get:

2.8 m \\times 48.75 m = H \\times 1.21 m

136.5 m = 1.21 m \\times H

To find H, divide both sides by 1.21 m:

H = 136.5 m / 1.21 m

H = 112.8099 m

So, the height of the tower is approximately 112.81 meters after rounding to two decimal places.

Answer for arc AB:

since we know FB is the perpendicular bisector of AC then we know AB is the same length as BC so: 2x + 5 = 3x - 2 put everything on the left side

2x + 5 + 2 = 3x -2 + 2    2x + 7 = 3x put the variables on one side

2x - 2x + 7 = 3x - 2x   7 = x  plug it in

2(7) + 5 = 19

AB = 19

Answer for segment DC:

since we know FB is the perpendicular bisector of AC then we know AD is the same as DC.

y + 8 = 5y put the variable on one side

y - y + 8 = 5y - y   8 = 4y simplify

8/4 = 4y/4

2 = y plug it in

5(2) = 10

DC = 10

Step-by-step explanation:

To find out the price lets divide

11.16/ 4 = 2.79 per pack

17.94/6= 2.99 per pack

24.96/8= 3.12 per pack

39.75/15= 2.65 per pack

2.65 is the cheapest out of all of the choices

Answer:

Step-by-step explanation:

The given table is

Packs     Cost ($)

   4           11.16

   6           17.94

   8           24.96

   15          39.75

So, the best value here refers to the cheapest napkins. To find their price per unit , we need to divide the cost of the pack by the number of packs

[tex]\frac{11.16}{4}= \$2.79\\\frac{17.94}{6}=\$ 2.99\\\frac{24.96}{8} =\$3.12\\\frac{39.75}{15}=\$2.65[/tex]

You can observe that the cheapest price is $2.65.

Therefore, the best choice is D. 15 packs for $39.75, because ti gives the best offer per pack.

Answer:

y = (-1/6)x^2

Step-by-step explanation:

Original function and graph:  y = x^2

Reflection across the x-axis is y = -x^2

Vertical scaling by a factor of 1/6:    y = (-1/6)x^2

The given parabola y=x^2 when reflected over the x-axis becomes y=-x^2. After applying a vertical scale factor of 1/6, it becomes y = -(1/6)x^2.

The parabola given, y=x^2, when reflected across the x-axis, results in a graph of y = -x^2.

Then, when we apply vertical scaling by a factor of 1/6, we have to multiply the y-values by this factor. If y = -x^2 is our equation after reflecting, then after scaling, it becomes y = -(1/6)x^2.

A key point to remember is that when a parabola is reflected over the x-axis, it flips upside down. Then, when it's vertically scaled by a factor, we multiply the y-values by the factor, which stretches or squishes the graph depending on the factor's value.

Answer:

The length of side BC is 2.8 units

Step-by-step explanation:

* Lets revise how to find the distance between two points

- If there are two points their coordinates are (x1 , y1) and (x2 , y2),

 then we can find the distance between them by this rule:

 d = √[(x2 - x1)² + (y2 - y1)²]

- Now lets solve the problem

∵ B = (3 , 3)

∵ C = (5 , 1)

- To find the length of BC use the rule of the distance above

- Let point B is (x1 , y1) and point C is (x2 , y2)

∵ x1 = 3 and x2 = 5

∵ y1 = 3 and y2 = 1

∴ BC = √[(5 - 3)² + (1 - 3)²]

∴ BC = √[(2)² + (-2)²]

∴ BC = √[4 + 4] = √8 = 2.8 units

* The length of side BC is 2.8 units

Step-by-step explanation:

F(X) = 2(5)^2x two times five equals 10. 10 to the power of two equals 100 because it's ten times ten. So F(X) = 100^x because that means it's just 100. Also F(x) = 4(25)^x because four times 25 equals 100.

Answer:

The graph shows the solution to the system inequalities

y ≥ -3x + 3 and y ≥ 2x ⇒ answer D

Step-by-step explanation:

* Lets study the graph to solve the question

- There are two solid lines, that means the sign of the inequalities

  are ≤ or ≥

- One of the two line passes through the origin and the other

  intersect the y-axis

- The shaded region is over the two lines, then the signs of the

  inequalities are ≥ (greater than or equal)

* Lets make the equations of the two lines

∵ The form of the equation is y = mx + c, where m is the slope of the

   line and c is the y-intercept

- The rule of the slope of the line wich passes through points (x1 , y1)

  and (x2 , y2) is m = (y2 - y1)/(x2 - x1)

- Y-intercept means the line intersect the y-axis at point (0 , c)

* Now lets find from the graph two points on each line to make the

 equations of the lines

# The line which passes through the origin

∵ Points (0 , 0) and (5 , 10) are on the line

- Let (0 , 0) is (x1 , y1) and (5 , 10) is (x2 , y2)

∴ m = (10 - 0)/(5 - 0) = 10/5 = 2

∴ The equation of the line is y = 2x + c

∵ The line passes through the origin

∴ c = 0

∴ The equation of the line is y = 2x

- The shaded is over the line

∴ The inequality is y ≥ 2x

# The line which intersect the y-axis at point (0 , 3)

∵ Points (0 , 3) and (1 , 0) are on the line

- Let (0 , 3) is (x1 , y1) and (1 , 0) is (x2 , y2)

∴ m = (0 - 3)/(1 - 0) = -3/1 = -3

∴ The equation of the line is y = -3x + c

∵ The line passes through the point (0 , 3)

∴ c = 3

∴ The equation of the line is y = -3x + 3

- The shaded is over the line

∴ The inequality is y ≥ -3x + 3

∴ The graph shows the solution to the system inequalities :

   y ≥ -3x + 3 and y ≥ 2x

4.0 - 4.9                    1

Step-by-step explanation:

The scale of equal intervals is characterized by a common and constant unit of measure that assigns a number equal to the number of units equivalent to that of the magnitude of the observed element. It is important to note that the zero point in the scales of equal intervals is arbitrary, and does not reflect at any moment absence of the magnitude that we are measuring.

This scale, besides having the characteristics of the ordinal scale, we find that the assignment of the numbers to the elements is so precise that we can determine the magnitude of the intervals (distance) between all the elements of the scale. Undoubtedly, we can say that the scale of intervals is the first truly quantitative scale and the characters that have this scale can be calculated all the statistical measures except the coefficient of variation.

The data is classified into classes divided into equivalent intervals. The range is then divided by the number of classes, which gives the common difference.

1. Define the number of equals intervals .

Each interval increase 0.9.

2. Make a frecuency table.

We select each country which is within the range of each class and we add in the frecuency column the countries that fall within the range of that class.
