(a) 3 EA
(b) BCA
(c) An B = {2,5,6}
(d) AU B = {7,9,10}
Anø=Ø
(e)
(f) n(AUB)

Answers

Answer 1

The statements are:

a) False

b) True

c) True

d) False.

e) True.

Which statements are true and which ones are false?

Here we have the two sets:

A = {2, 5, 6, 7, 9, 10) and B = {2, 5, 6}

The first statement is:

a) 3 E A

That says "the number 3 belongs to set A". That clearly is false, as the set A does not contain the element 3.

b) B C A

The statement says:

Set B is included in set A. This is true, as all the elements of set B also belong to set A.

c) A n B = {2,5,6}

This is true, that is the intersection between A and B (the intersection between two sets is the set of common elements)

d) AU B = {7,9,10}

This is false, U refers to the union between the two sets, here we should have

A U B = A = {2, 5, 6, 7, 9, 10}

e) Anø=Ø

This is true, trivially all the sets contain the element {∅}

A crew of highway workers paved 12 mile in 14 hour. If they work at the same rate, how much will they pave in one hour?

Answers

Answer:

0.857 miles in 1 hour

Step-by-step explanation:

It is given that,

A crew of highway workers paved 12 mile in 14 hour.

We need to find how much will they pave in 1 hour if they work at the same rate.

14 hours = 12 miles

To find how much they pave in 1 hour, we must divide 12 by 14 as follows :

[tex]1\ \text{hour}=\dfrac{12}{14}\ \text{miles}\\\\=0.857\ \text{miles}[/tex]

Hence, they pave 0.857 miles in 1 hour.0.857 miles in 1 hour.

Aniyah is driving home at a constant speed. After 20 minutes, she is 70 miles from home. What equation models her distance from home, y, as a function of time, x?

Answers

Answer:

The equation that models her distance from home, y, as a function of time, x will be:

y = 3.5x

Step-by-step explanation:

We know that the slope-intercept form of a linear function is

y = mx+b

Here m is the slope and b is the y-intercept

Please note that slope is also termed as 'rate of change'.

Given that Aniyah is driving home at a constant speed.

at t = 20 minutes, she has covered 70 miles

so the rate of change = 70/20

                                     = 3.5 miles per minute

Let y be the distance from homeLet x be the time

Finding the y-intercept by substituting m = rate of change = 3.5 and the point (20, 70)

y = mx+b

70 = 3.5(20) + b

b = 70 - 70

  = 0

Thus, the equation becomes

y = mx+b

y = 3.5x + 0

y = 3.5x

Therefore, the equation that models her distance from home, y, as a function of time, x will be:

y = 3.5x

Find the measure of the angle shown by the arrow(in radians)

Answers

Answer:

-7π/3 or -420 degrees

Step-by-step explanation:

So we know that the arrow has made one full rotation and that it is moving in a clockwise direction. So already we have -2π degrees.

The arrow stops at π/6 before the next π/2 rotation. Therefore we find the difference between the two.

π/2 - π/6

3π/6 - π/6 = 2π/6

π/3

Since this is still clockwise, we make this negative. So the measure of the angle shown by the arrow is -2π - π/3

Answers

Answer:

m<4 = 44°

Step-by-step explanation:

m<8 = 34°

m<9 = 40°

m<3 = 62°

m<2 = 34° + 40° (exterior angle theorem of a triangle)

m<2 = 74°

m<3 + m<4 + m<2 = 180° (sum of ∆)

62° + m<4 + 74° = 180° (substitution)

m<4 + 136° = 180°

m<4 = 180 - 136 (substitution property of equality)

m<4 = 44°

Answers

Answer:

[tex]|z| = 27[/tex] -- Modulus

[tex]\theta = \frac{\pi}{3}[/tex] --- Argument

Step-by-step explanation:

Given

[tex]((\sqrt 3)(cos\frac{\pi}{18} + i\ sin\frac{\pi}{18}))^6[/tex]

Required

Determine the modulus and the argument

We have that:

[tex]z = ((\sqrt 3)(cos\frac{\pi}{18} + i\ sin\frac{\pi}{18}))^6[/tex]

Expand:

[tex]z = (\sqrt 3)^6(cos\frac{\pi}{18} + i\ sin\frac{\pi}{18})^6[/tex]

[tex]z = 27(cos\frac{\pi}{18} + i\ sin\frac{\pi}{18})^6[/tex]

A complex equation can be expressed as:

[tex]z = |z| e^{i\theta}[/tex]

Where

[tex]|z| = modulus[/tex]

[tex]\theta = argument[/tex]

Where

[tex]e^{i\theta} = (cos\frac{\pi}{18} + i\ sin\frac{\pi}{18})[/tex]

So:

[tex]z = 27(cos\frac{\pi}{18} + i\ sin\frac{\pi}{18})^6[/tex] becomes

[tex]z = 27(e^{i\frac{\pi}{18}})^6[/tex]

By comparison:

[tex]e^{i\theta} = (e^{i\frac{\pi}{18}})^6[/tex]

This gives:

[tex]{i\theta} = i\frac{\pi}{18}}*6[/tex]

[tex]{i\theta} = i\frac{6\pi}{18}}[/tex]

[tex]{i\theta} = i\frac{\pi}{3}}[/tex]

Divide through by i

[tex]\theta = \frac{\pi}{3}[/tex]

Hence, the modulus, z is:

[tex]|z| = 27[/tex]

And the argument [tex]\theta[/tex] is

[tex]\theta = \frac{\pi}{3}[/tex]

A cash register contains coins. • 10 pennies • 11 nickels • 13 dimes • 6 quarters A cashier will randomly choose two coins one at a time without replacement. What is the probability that the cashier will choose a penny first, followed by a dime?
F 13/160
G 1/12
H 13/245
J 7/12​

Answers

♡ Answer ♡

G) 1/12

♡ Step-by-step explanation ♡

  In order to figure out this problem, we have to take a few relatively simple steps.

  First, we must count the total number of coins in the cash register. Do not change the value of these coins. Simply take the numbers listed in the problem and add them up. Your process for completing this step should look something like this: 10+11+13+6 equals 40. With this being said, there are 40 coins in the cash register.

  Next, we must remember the values of the two coins the question is asking for: pennies and dimes. Keep in mind that, out of all 40 coins, 10 of them are pennies and 13 of them are dimes.

  Then, we write the fractions used to find the answer to this problem. In the question, the cashier (hypothetically) draws a penny first, and then a dime. This means a penny is drawn before a dime is drawn. (Although it seems like a miniscule detail, this knowledge is actually something extremely important to remember. This small piece of information can actually change the entire answer if not used properly.)

  In this problem, the cashier would choose a single penny out of the 10 in contrast to the total 40 coins. Since there are 10 pennies overall, and 40 coins overall, the probability of choosing a penny first is 10/40.

  After we complete the probability of choosing a penny before all else, we must find the probability of choosing a dime after choosing a penny. Since the dime will be chosen after the penny is chosen, one coin will be gone: the chosen penny. So, the total amount of coins within the cash register changes (or more specifically decreases (by 1)) from 40 to 39. However, the amount of dimes, 13, stays the same. With this information in mind, we can write a fraction of 13/39 for the probability of choosing a dime after choosing a penny.

  Finally, now that we have both probability fractions, we can figure out the answer to the question. In order to do this, we multiply and simplify both fractions. 10/40*13/39 is 130/1560. 130 ÷ 130 is 1. 1560 ÷ 130 is 12. 1 ÷ 12 can also be written as 1/12. Therefore, the answer to this problem is G) 1/12.

(The paragraph and author's note below are technically optional thought processes and information, but read them if you wish. Although I would recommend reading further, considering another way to solve the question is mentioned, it is entirely you (the reader's) choice.)

  You can also check this answer through the other/alternate way of solving this problem: by simplifying both probability fractions before you multiply them. 10/40 can be simplified to 1/4. 13/39 can be simplified to 1/3. After doing this, we multiply both simplified probability fractions in order to find, or in this case check, the answer. 1/4*1/3 is 1/12. 1/12 is the same fraction as the one present in choice G. This is the same answer as the one we previously got. This enforces the idea that G) 1/12 is indeed the answer to this question.

  A/N (Author's Note): Although it took quite a while to jot down, this was truly a blast to write and explain! I hope this helped those that needed/wanted it. Have a wonderful week reader(s)!

d) HL and HK are distinct lines that intersect

a) The common point in lines LN and PN  is N and it is the intersection point.

b) Any three non-collinear locations inside a plane can be used to give it a name. Points H, J, and K cannot be combined because an unlimited number of planes cross through them. Think about the flat piece of paper rotating about this axis (like a propeller). We can only build one specific plane if the points are not all along the same line.

I'll choose P, H, and J as the non-collinear points to give the object the name Plane PHJ. There may be other solutions.

c) Because they are on the same line, points H, J, and K are collinear. Fill up the answer box by selecting either H or K. I'll choose point K.

d) Line HK and point P are parallel. Both of them are present on the same flat piece of paper or on the same flat plane.

That flat plane can be compared to the surface of the earth, but point N is located underneath. Therefore, the ground plane and point N wouldn't be coplanar.

The area of the rectangular room would be 84 square meters.

What is the area of the rectangle?

The area of a rectangle is defined as the product of the length and width.

The area of a rectangle = L × W

Where W is the width of the rectangle and L is the length of the rectangle

A rectangular room that is 9 3/5 meters long and 8 3/4 meters wide

According to the given question, we can write the dimension as:

The width of the room = 8 3/4 meters = 35/4 meters

The length of the room = 9 3/5 meters = 48/5 meters

The area of the room = width of the room ×  length of the room

The area of the room = 35/4 × 48/5

Apply the multiplication operation,

The area of the room = 84 square meters

Therefore, the area of the room is 84 square meters.
