Answer:

[tex]10^{-4} = 0.0001[/tex]

Step-by-step explanation:

Negative exponents make the base a reciprocal:

[tex]x^{-1} = \frac{1}{x}\\x^2 = \frac{1}{x^2}\\[/tex]

Therefore, we can rewrite [tex]10^{-4}[/tex] as:

[tex]10^{-4} = \frac{1}{10^4} = \frac{1}{10000} = 0.0001[/tex]

10^-4 = 0.0001

1 x 10^-4 = 10^-4

It's a negative power - so you divide the 1 by 10000 - to get 0.0001.

Same as 1/10000

Step-by-step explanation:

A complete probability model should sum up the probability to 1

by adding them up, you will find the sum as 1/12 + 8/12 + 3/12 = 12/12

So, they can be a complete probability model with 3 outcomes "2", "3" & "4"

The probability that “a child ticket is bought for a play” and “the play is performed in the afternoon" is 36/363.

Probability is the likelihood that a stated event would occur. The probability that the event would happen lies between 0 and 1.

The probability that “a child ticket is bought for a play” and “the play is performed in the afternoon" = 36 / total number of tickets bought

36 / (36 + 12 + 127 + 188) = 36 / 363

Answer:

C) y = 16 feet

Step-by-step explanation:

the corresponding sides in ABCD are equal to their corresponding sides by EFGH multiplied by something

all values are in feet

let x represent the unknown side in ABCD

ABCD lengths in order: x, 30 , 40 , 60

let a and b represent the unknown sides in EFGH

EFGH lengths in order: 6, 12, a, b

thus, 30 corresponds to 12 as they are both the second shortest sides

corresponding side in EFGH * something = corresponding side in ABCD

12 * something = 30

let something be r

12 * r = 30

divide both sides by 12 to isolate r

r = 30/12

thus, to get a side in ABCD, we multiply the corresponding side in EFGH by 30/12

we want to find the second longest side in EFGH. the corresponding side to that in ABCD is 40, as 40 is the second longest side in ABCD

let the second longest side in EFGH = y

y * 30/12 = 40

multiply both sides by 12/30 to isolate y

40 * 12 / 30 = y = 16

y = 16 feet

Answer:

  D) 80%

Step-by-step explanation:

To find the fraction of women surveyed who prefer salads, we need to know something about how many were surveyed, and how many of those preferred salads.

For this purpose, we can effectively ignore the percent signs in the table, and consider that it represent 100 people surveyed.

__

Of the 100 people surveyed, 40 were women. Of the 40 women, 32 preferred salads. That is, 32/40 = 8/10 = 80% of the women surveyed preferred salads.

_____

Additional comment

When dealing with percentages, one must always keep in mind the base the percentage is referring to. For all of the numbers in the table, the base is the total number of participants in the survey.

For the percentage that is the answer to the question, the base is the number of women surveyed (or something proportional to that number).

Answer:

The clock face is divided into sixty equal parts, each minute. The minute hand is located on the 20 minute mark at 6:20, the hour hand located between the 30 minute mark and the 35 minute mark. When the minute hand goes all sixty minutes, the hour hand only moves five, so to figure out the location of the hour hand, we look at how much the hour has progressed, in this case 20 minutes, or one third of the hour. So the minute hand has moved one third of the way through the hour, so has the hour hand moved one third of the way through the five minutes, or, five thirds of a minute, which is one and two thirds minute, one minute forty seconds. That puts the hour hand at thirty minutes plus one minute and forty seconds—at 31min 40sec—which is 11min 40sec farther than the minute hand.

Step-by-step explanation:

The equation for the path of a launched projectile contains the vertex (5, 120) and the point (25, 80) on the boundary is shown in the graph.

It is defined as the graph of a quadratic function that has something bowl-shaped.

The path of the launched projectile will a parabola.

We have the vertex of the parabola (5, 120)

The standard equation in terms of vertex (h, k)

[tex]\rm y = a(x-h)^2+k[/tex]

Plug the points:

[tex]\rm y = a(x-5)^2+120[/tex]

To find the value of “a” plug point (25, 80)

[tex]\rm 80 = a(25-5)^2+120[/tex]

a = -1/10

Plug this into the equation;

The path of the equation:

[tex]\rm y = \dfrac{-1}{10}(x-5)^2+120[/tex]

Thus, the equation for the path of a launched projectile contains the vertex (5, 120) and the point (25, 80) on the boundary is shown in the graph.

According to the rational root theorem, the function that has the same set of potential rational roots is f(x) = 3x^5 – 2x^4 – 9x^3 + x^2 – 12.

Given the function:

g(x) = 3x^5 – 2x^4 + 9x^3 – x^2 + 12

We would have to find the rational roots and this would be done by:

Identifying the factors of 12 and 3.

After this, there would have to be an analysis of the factors and we can see that the correct answer is f(x) = 3x^5 – 2x^4 – 9x^3 + x^2 – 12.

8. P = 48 cm A = 83

9. P =32 cm A = 60

Step-by-step explanation:

P = add all sides together

A = base times height

Answer:

8. P = 48 cm, A = 83 cm²

9. P = 36 cm, A = 56 cm²

Step-by-step explanation:

The trick with irregular shaped objects areas is to split them up into several rectangles. Perimeters is just filling in the missing sides using the other sides and adding them all up.

After finding the missing sides for the first figure, the perimeter would be:

5 + 10 + 4 + 3 + 11 + 3 + 2 + 10 = 48 cm

For the area, we split the figure into the vertical rectangle on top and the horizontal rectangle on the bottom. You'll see that the vertical rectangle has an area of 50 squared cm (5 * 10), while the area of the other rectangle is 33 squared cm (3 * 11), so the area of the whole figure is 50 + 33 = 83 squared cm.

Use this same method for the next figure, and you should get that the perimeter is 36 cm and the area is 56 squared cm.

Volume is a three-dimensional scalar quantity. The amount of coffee that can be put in the tumbler is 11.486 in³.

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

Given the diameter of the coffee, the tumbler is 3inches, while the height is 7 inches, also, 0.5 inches is needed to be left to fit the lid on the top. Therefore, the height of the tumbler will be 6.5 inches (7-0.5).

Now, the volume of the coffee tumbler will be,

The volume of the coffee tumbler = (π/4)×D²×h

                                                         = (π/4)×(1.5)²×6.5

                                                         = 11.486 in³

Hence, the amount of coffee that can be put in the tumbler is 11.486 in³.
