Answer:

Yes

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"

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.

Answer:

x= 14

Step-by-step explanation:

When the triangles are similar, they should have a similar ratio that makes one side equal to another. In this case, the ratio is 1.5 as 24 divided by 16 is 1.5. Now, taking the side that is "similar" to the x-value which is 21, we divided 21 by 1.5 resulting in x= 14.

Answer:

x = 14

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:

x = 15,  45 degree angle

Step-by-step explanation:

2x + 15 and 6x - 45 adds up to 90 degrees

(2x + 15) + (6x - 45) = 90

combine like terms:

2x + 6x = 8x

15 + (-45) = -30

8x - 30 = 90

8x - 30 + 30 = 90 + 30

8x = 120

8x / 8 = 120 / 8

x = 15

2(15) + 15

30 + 15 = 45 degree angle

6(15) - 45

90 - 45 = 45

Answer:

x = 15.

Step-by-step explanation:

The figure is a square so opposite sides are congruent and parallel.

The 2 angles marked are interior alternate angles, so they are congruent.

Therefore:

2x + 15 = 6x - 45

15 + 45 = 6x - 2x

4x = 60

x = 15.

Answer:

-6

Step-by-step explanation:

Answer:

c)  124.96

Step-by-step explanation:

Geometric series:  100 + 20 + ... + 0.16

First we need to find which term 0.16 is.

General form of a geometric sequence: [tex]a_n=ar^{n-1}[/tex]

(where a is the first term and r is the common ratio)

To find the common ratio r, divide one term by the previous term:

[tex]\implies r=\dfrac{a_2}{a_1}=\dfrac{20}{100}=0.2[/tex]

Therefore, [tex]a_n=100(0.2)^{n-1}[/tex]

Substitute [tex]a_n=0.16[/tex] into the equation and solve for n:

[tex]\implies 100(0.2)^{n-1}=0.16[/tex]

[tex]\implies (0.2)^{n-1}=0.0016[/tex]

[tex]\implies \ln(0.2)^{n-1}=\ln0.0016[/tex]

[tex]\implies (n-1)\ln(0.2)=\ln0.0016[/tex]

[tex]\implies n-1=\dfrac{\ln0.0016}{\ln(0.2)}[/tex]

[tex]\implies n=\dfrac{\ln0.0016}{\ln(0.2)}+1[/tex]

[tex]\implies n=5[/tex]

Therefore, we need to find the sum of the first 5 terms.

Sum of the first n terms of a geometric series:

[tex]S_n=\dfrac{a(1-r^n)}{1-r}[/tex]

Therefore, sum of the first 5 terms:

[tex]\implies S_5=\dfrac{100(1-0.2^5)}{1-0.2}[/tex]

[tex]\implies S_5=124.96[/tex]

The statement second, statement fourth, and statement fifth are correct as the reflection line is y = -4.

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.

The lower bound of the confidence interval is 0.55.

A confidence interval for a proportion is a range of values that is likely to contain a population proportion with a certain level of confidence.

Construct a confidence interval of the population proportion at the given level of confidence x equals = 540, n equals = 900, 96% confidence.

The value of p is;

[tex]\rm p=\dfrac{x}{n}\\\\p =\dfrac{540}{900}\\\\p=0.6[/tex]

The standard error of the proportion is:

[tex]\rm \sigma_p=\sqrt{\dfrac{p(1-p)}{n}} \\\\ \sigma_p=\sqrt{\dfrac{0.6(1-0.6)}{540}} \\\\ \sigma_p=\sqrt{\dfrac{0.6\times 0.4}{540}} \\\\ \sigma_p=\sqrt{\dfrac{0.24}{540}} \\\\ \sigma_p=\sqrt{0.00044}\\\\ \sigma_p=0.02[/tex]

The critical z-value for a 94% confidence interval is z = 2.04

The margin of error (MOE) can be calculated as:

[tex]\rm Margin \ of \ error=\sigma_p \times z =2.04 \times0.02 =0.04[/tex]

Then, the lower bound of the confidence interval is;

[tex]Lower \ bound =p-x\times \sigma_p=0.6-0.04=0.55[/tex]

Hence, the lower bound of the confidence interval is 0.55.

Answer:

$115

Step-by-step explanation:

The cost of the labor per hour is $115.

The total amount that the technician charged her is the sum of the cost for the total hours worked and the costs of the parts.

Total charge = cost of total hours worked + cost of parts

$749 = $59 +  cost of total hours worked

Cost of total hours worked = $749 - $59

Cost of total hours worked = $690.

Answer:

Volume: 203,594

Surface Area: 105,237

----------------------------------------------------------------------------------------------------------

Let's start with surface area because it is a bit complex.

[tex]A = 5 ah + \frac{1}{2} \sqrt{5(5 + 2 \sqrt{5})}~a^2[/tex]

Now, we must break all of these factors into an equation.

remember, the height is 4, the base is 172

[tex]A = 5 * 172 * 4 + \frac{1}{2} * \sqrt{5 * (5 + 2 * \sqrt{5})} * 172^2[/tex]

[tex]A = \sf 1.05237 * 10^5 = 105,237[/tex]

So that should wrap things up for surface area, being 105,237

________________________________________________________

Now, we move on to the volume of this pentagonal prism.

[tex]A = \frac{1}{4} \sqrt{5(5 + 2 \sqrt{5})}~a^2h[/tex]

Similar to surface area, but different.

[tex]A = \frac{1}{4} * \sqrt{5 * (5 + 2 * \sqrt{5})} * 172^2 * 4[/tex]

And the result of this is...

[tex]A = \sf 2.03594 * 10^5[/tex]

Which is also equal to ⇒ 203,594

Answer:

≈ 11.7 m

Step-by-step explanation:

using Pythagoras' identity in the right triangle.

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let x be the measure of the second leg , then

x² + 15² = 19²

x² + 225 = 361 ( subtract 225 from both sides )

x² = 136 ( take square root of both sides )

x = [tex]\sqrt{136}[/tex] ≈ 11.7 m ( to the nearest tenth )

A: Yes, the sum of two sides are greater than the third side.

B: Yes, the sum of two sides are greater than the third side. (Would be an equiilateral triangl.)

C: No, the sum of two sides are less than the third side.

In general, To determine if 3 side lengths are a triangle, use the triangle inequality theorem, which states that the sum of 2 sides of a triangle must be greater than the third side. Therefore, all you have to do is add together each combination of 2 sides to see if it's greater than the third side.
