D. Approximately .00000
E. All of the above
F. none of the above

Answers

Answer 1

The  p-value of zero, while theoretically possible is effectively impossible, a p-value of .00000 is written as is

option A, "< .01".

It is important to first understand what a p-value represents. A p-value is a statistical measure that indicates the likelihood of obtaining the observed results of a study or experiment by chance, assuming that there is no true effect or difference between groups.

In hypothesis testing, a p-value of less than .05 (or .01, depending on the level of significance chosen) is typically considered to be statistically significant, indicating that the observed results are unlikely to be due to chance alone.

However, a p-value of exactly zero is not possible, as it would mean that the observed results are absolutely certain and could not have occurred by chance. Therefore, a p-value of .00000 (or any other extremely small value) is typically reported as "< .01" or something similar, indicating that the p-value is less than the chosen level of significance (in this case, .01).

Therefore, option A, "< .01", is the most accurate way to represent a p-value of .00000. The other options are either not precise enough (B and D), or incorrect (C and F).

A p-value of exactly zero is impossible, and a p-value of .00000 (or any other extremely small value) is typically reported as "< .01" to indicate that it is less than the chosen level of significance.

Which rule can be used to describe the growth of the y-values of the function y=12^(x) each interval from x=-1 to x=3

Answers

A rule which describes the growth of the y-values of the function y=12^x over each interval is "multiply by 12."

How to determine the rule?

By critically observing the given function, we can logically deduce that it is an exponential function. Also, the initial value of this exponential function is 1 with a growth factor is 12.

For instance, we have:

At x = -1

y = 12^(-1)

y = 1/12

At x=0

y = 12^(0)

y = 1

At x = 1

y = 12^(1)

y = 12

A car can travel 161 miles on 7 gallons of gas. how much gas will it need to go 368 miles?

Answers

Answer:

16 gallons of gas

Step-by-step explanation:

Two ways to answer this

1:

Find how many miles per gallon the car can go. Then, divide the amount the car needs to go with the miles per gallon. This gets you the gallons of gas needed to go the amount. In this case, 161 ÷ 7 = 23. 368 ÷ 23 = 16.

2:

Make a proportion. [tex]\frac{161}{7} = \frac{368}{x}[/tex]. Solve for x. 161 and 7 cancel out to get 23. [tex]\frac{23}{1} = \frac{368}{x}[/tex]. Now you can either divide 368 and 23 and multiply the quotient by 1 to get x, or you can cross multiply to get an equation you can solve. In the first case, 368 ÷ 23=16. 1*16=16. x=16. In the second case, 23x=368. Divide both sides by 23 and you get x = 16.

Determine whether the triangles can be proved similar. If they are similar, write a similarity statement. If they are not similar, explain why.

Answers

Answer:

They are similar.  Triangle abc is similar to triangle edc.

Step-by-step explanation:

To prove that triangles are similar, you must show that the 3 angles in one triangle are equal to the 3 angles in the other triangle.  We know that they both have a 50 degree angle.  We can also see that they both have a right angle.  That means that the 3rd angle must also equal 40 (180-90-50).  So by AAA the two triangles are congruent.

Answer:

Q9 - B) 8Q10 - D) 4.5

========================

Question 9

We have a diagram and need to find the number of routes without repeat paths:

[tex]ABCA[/tex] or [tex]ACBA[/tex]

We can see that there is one route from A to B, two routes from B to C and two routes from C to A. This is same on reverse order.

This gives us the number of routes:

[tex]ABCA = 1*2*2 = 4[/tex][tex]ACBA = 2*2*1 = 4[/tex]

Total number is:

[tex]4 + 4 = 8[/tex]

The matching answer choice is B

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

Question 10

From the given we can observe that:

ABC and DCE are similar triangles, since they have same angle at vertex E (vertical angles are equal) and both are right triangles.

From similarity we get same ratio of corresponding sides:

[tex]AE/DE = AB/CD = 3/9 = 1/3[/tex]

We can find areas of triangles ACD and ECD and subtract to get the area of triangle AEC:

[tex]S_{ACD} - S_{ECD} = S_{AEC}[/tex]

As per ratio of corresponding sides:

[tex]AE/DE = 1/3[/tex]

As per segment addition:

[tex]AE + DE = AD = 4[/tex]

From the two equations above we get:

[tex]DE = 3/4*AD = 3/4*4 = 3[/tex]

Now, the required area is:

[tex]S_{ACD} - S_{ECD} = 1/2(4*9) - 1/2(3*9) = 4.5[/tex]

This is matching the answer choice D

Answer:

9)  B. 8

10)   D. 4.5

Step-by-step explanation:

Question 9

For ease of visualization, label the different legs of the journey on the diagram (see attachment).

The journey needs to start and end at point A, go through points B and C (in any order), and not travel any road twice.

The different routes are:

AB (u), BC (x), CA (w)AB (u), BC (y), CA (w)AB (u), BC (x), CA (z)AB (u), BC (y), CA (z)AC (w), CB (x), BA (u)AC (z), CB (x), BA (u)AC (w), CB (y), BA (u)AC (z), CB (y), BA (u)

Therefore, there are 8 different routes.

Question 10

Triangles EDC and EAB are similar since they have congruent angles:

∠EDC ≅ ∠EAB  (both right angles)∠DEC ≅ ∠AEB  (vertical angle theorem)

Therefore, their corresponding sides are in proportion.

⇒ CD : BA = ED : EA

⇒ 9 : 3 = ED : EA

⇒ 3 : 1 = ED : EA

Since we know that AD = 4:

⇒ ED = 3

⇒ EA = 1

Find the perimeter of the rhombus below, given that a = 7 and b = 14. (round your answer to one decimal place, if necessary.)

Answers

If the value of a is 7, b is 14 in the rhombus then the perimeter of the rhombus is equal to 31.3 units.

Given that the value of a is 7,b is 14.

We are required to find the perimeter of the rhombus.

The values which are given to us are of the lengths of diagonals of rhombus.

Perimeter of the rhombus is equal to 4 times the side of the rhombus. So in order to find the perimeter of the rhombus we need the side of the rhombus not the diagonals.

When we draw the diagonals in the rhombus it forms four right angled triangle in which the Base is equal to 7/2 units and 7 is the perpendicular.

We have to use pythagoras theorem to find the hypotenuse which is the side of the rhombus.

Suppose base is BC , perpendicular is AB and hypotenuse is AC.

AC=[tex]\sqrt{7^{2} +7/2^{2} }[/tex]

=[tex]\sqrt{49+49/4}[/tex]

A boss plans a business meeting at Starbucks with the two engineers below him. However, he fails to set a time, and all three arrive at Starbucks at a random time between and p.m. When the boss shows up, if both engineers are not already there, he storms out and cancels the meeting. Each engineer is willing to stay at Starbucks alone for an hour, but if the other engineer has not arrived by that time, he will leave. What is the probability that the meeting takes place

Answers

The probability that the meeting takes place is 7/24.

What is the probability?

Probability is defined as the ratio of the number of favorable outcomes of an event to the total number of possible outcomes(sample space) of the event.

It is given by

P(A) = n(A)/n(S)

Where A - event, S - sample space

Calculation:

From the given data,

The probability, if the engineers arrive in the first hour and the boss arrives in the second hour is 1/8,

So, the meeting will be held i.e., p = 1.

The probability, if all the three arrive in the same hour (first or second)

= 1/8 + 1/8

= 1/4

So, the meeting will be held only if the boss (he may arrive first, second, or last) arrives last, the probability is 1/3

The probability, if one of the engineers arrives in the first hour while the other engineer and the boss arrive in the second hour is

= 1/4

So, the meeting will be held only if the second engineer arrives before the boss and before the first engineer leaves, the probability is 1/3

Thus, the final probability for the meeting to take place is

= (1/8) × 1 + (1/4) × (1/3) + (1/4) × (1/3)

= 7/24

Therefore, the required probability is 7/24.

How to determine the length of the belt around the two pulleys?

In this question we must determine the perimeter of a belt around two pulleys, whose centers are 10 centimeters apart. This perimeter is the sum of part of the circumference of small pulley, part of the circumference of the big pulley and two times the segment tangent to the two pulleys.

Now we proceed to determine the parts of the perimeter of the belt:

Big pulley

s' = (214.92° / 180°) · π · (6 cm)

s' ≈ 22.506 cm

Small pulley

s'' = (145.08° / 180°) · π · (3 cm)

s'' ≈ 7.596 cm

Tangent segments

l = (10 cm) · sin 72.54°

l ≈ 9.539 cm

Lastly, the perimeter of the belt is:

L = s' + s'' + 2 · l      (1)

L = 22.506 cm + 7.596 cm + 2 · (9.539 cm)

L = 49.180 cm

Is it possible to make a number out of 8 different digits that is

Answers

Answer:

  1,123,449,768

Step-by-step explanation:

The smallest number composed from 8 different digits that is divisible by each of those digits appears to be the 10-digit number ...

  1,123,449,768

Restrictions

If the number is to be divisible by an even digit, it must be even. That means it cannot end in the digit 5, so 5 cannot be one of the digits. We disallow division by 0, so 0 cannot be one of the digits.

The remaining 8 digits total 40, so cannot form a number divisible by 3, 6, or 9. In order to make such a number, we must add 5 to the digit total, but cannot do so using the single digit 5.

Choices for added digits include {1, 4} and {2, 3}. Adding 9+5 = 14 to the digit total would also work but would guarantee the resulting number is not the minimum possible.

Further divisibility restrictions

The digits we have to work with are now {1, 1, 2, 3, 4, 4, 6, 7, 8. 9}. We know that an even number constructed from these digits will be divisible by 1, 2, 3, 6, and 9. To make it divisible by 4, 7, and 8, it must be a multiple of the LCM of those numbers.

The least possible number will use the smallest digits first, so will start ...

  112344...

The remaining digits, 6, 7, 8, 9, need to form a number that will be divisible by 56 when appended to the 6 digits already used. Those 6 digits form a number, 1123440000, that has a remainder of 32 when divided by 56. Hence we need to use the digits 6, 7, 8, 9 to make a number with a remainder of 24 when divided by 56. There are 24 permutations of the digits 6, 7, 8, 9. Half of these are odd numbers

The one number formed from digits 6, 7, 8, 9 that is divisible by 56 with a remainder of 24 is 9768.

Smallest Number

The smallest number comprised of 8 different digits and divisible by each of them is the 10-digit number 1,123,449,768.

Answers

Answer:

53

Step-by-step explanation:

Let yazid's score be x

x + x + 17 + 2x = 161

4x + 17 = 161

4x = 144

x = 36

jack = x + 17

jack = 53

Answer:

Jack:  36

Bonus:  Yazid:  53 and Susan:  72

Step-by-step explanation:

Let J, Y, and K stand for Jack, Yazin, Susan's scores.

We are told that:

J = Y + 17  [Jack scored 17 marks more than Yazid]

S = 2Y  [Susan scored twice Yazid's score]

J + Y + S = 161  [total score is 161]

Substitute the first two expressions into the last equation:

J + Y + S = 161

(Y+17) + Y + (2Y) = 161

4Y = 144

Y = 36

Use Y = 36 to find the other scores:

J = Y + 17

J = 36 + 17

J = 53

S = 2Y

S = 2*(36)

S = 72

1. Describe three different ways to solve a quadratic equation. Describe the strengths and limitations of each method, and explain how you would decide which one to use to solve a particular problem.
2. Derive the quadratic formula from the standard form (ax2 + bx + c = 0) of a quadratic equation by following the steps below.
Divide all terms in the equation by a.
Subtract the constant (the term without an x) from both sides.
Add a constant (in terms of a and b) that will complete the square.
Take the square root of both sides of the equation.
Solve for x.
3. Write a linear equation that intersects y = x2 at two points. Then write a second linear equation that intersects y = x2 at just one point, and a third linear equation that does not intersect y = x2. Explain how you found the linear equations.

Which of the following is a perfect square trinomial?
a. x^2+10x+25
b. x^2+6x+13
c. x^2+100
d. x^2+3x+9

Answers

Answer:

a. x² + 10x + 25

Step-by-step explanation:

because

(x + 5)² = (x + 5)(x + 5) = x² + 5x + 5x + 25 = x² + 10x + 25

so, it is a perfect square of (x + 5).

During a very cold winter, water pipes sometimes burst because:

Answers

The water pipe sometimes bursts in winter because of the flowing water getting transformed into freezing water due to drop in temperature and the volume increases creating more pressure on the wall pipes.

Bursting of Water Pipes During a Very Cold Winter

The straightforward explanation is that during very cold winters, as water freezes into ice, it expands, causing solid ice to fill a larger volume than the liquid that was previously flowing through the pipes.

As we know that, the pressure P increases with increase in volume, V, the increased volume of frozen water leads to increase in the pressure inside the pipe.

The pressure that the ice builds up inside the pipes could rupture the pipe walls.

Each of the genes has only two alleles, one of which is completely dominant to the other.Each student in the class performed a parental cross between a fly that is true-breeding for ebony body and vestigial wings and a fly that is true-breeding for gray body and long wings. Each student then crossed several pairs of the F1 flies and determined the phenotypes of 500 of the resulting F2 flies with respect to body color and wing shape. The students in the class averaged their data for the frequencies of the four possible phenotypes (Table 1).The students performed a second cross. The parental cross was between flies that are true-breeding for gray bodies and long wings and flies that are true-breeding for ebony bodies and curly wings. They crossed pairs of F1flies and determined the phenotypes of the resulting F2flies. The students found an approximate 3:1 ratio of flies with the dominant phenotype (gray bodies and long wings) to flies with the recessive phenotype (ebony bodies and curly wings). Only a few of the flies expressed the dominant phenotype of one trait and the recessive phenotype of the other trait.(b) Using the template, construct an appropriately labeled graph, including error bars, to represent the data in Table 1.
