D?
and proof.

Answers

Answer:

C

Step-by-step explanation:

Key skills needed: Inequalities

1) We are given that inequality.

The inequality is b ≤ 11 (any variable would work instead of "b")

--> It is "≤" and not "<" since there is a filled/shaded dot on the 11.

2) This means we solve all the ones with less than or equal to symbols.

A does not have a ≤ symbol, so A cannot be it

3) Solve each one:

B --> -k [tex]\leq[/tex] 11

Divide by -1 on both sides and get [tex]k \geq -11[/tex]  B cannot be it

C --> 44 ≥ b + 33

Subtract 33 from both sides and get b [tex]\leq[/tex] 11

Therefore C is your answer       C can be it!!

If you want to check D --> x -11 ≤ 11

Add 11 to both sides and get x ≤ 22 D cannot be it

Hope you understood and have a nice day!!

Answer:

C. 44 ≥ b+33

Step-by-step explanation:

Lets think about this. It really doesn't matter what the variable is also, we should immediately disregard A because its not a greater than or equal to sign. You should also, you how I can to this conclusion was that, SHADED circle in are always greater than or equal to or less than or equal to. EMPTY circle means greater than or less than. Therefore, you have already taken down A. B on the other hand would've worked if not for the fact that the variable is a negative. D on the other hand if you do the math of what the number line would be 11 -11=0 while it is less than or equal to 11. To get 11 or anything else other than below 0 you would fall off the number line. Therefore, because 44≥b+33 would be 44≥11+33 or anything less would work.

C. 44 ≥ b + 33

Answer:

C = 133.33°

Step-by-step explanation:

Apply the Law of Cosines to find angle C:

[tex] Cos(C) = \frac{a^2 + b^2 - c^2}{2ab} [/tex]

Where,

a = 8.5 cm

b = 4.1 cm

c = 11.7 cm

Plug in the values

[tex] Cos(C) = \frac{8.5^2 + 4.1^2 - 11.7^2}{2*8.5*4.1} [/tex]

[tex] Cos(C) = \frac{-47.83}{69.7} [/tex]

[tex] Cos(C) = -0.6862 [/tex]

[tex] C = Cos^{-1}(-0.6862) [/tex]

C = 133.33°

Given the sets above, select all (or the null set) of the element of: B

Answers

Given:

Universal set = {a, b, c, d, e, f, g, h}

A = {a, b, c, d}

B = {a, d, e}

C= {c, f, g, h}

To find:

The elements of set B'.

Solution:

Let universal set be U.

U = {a, b, c, d, e, f, g, h}

We know that,

Compliment of a set = Universal set - Set

It means,

[tex]B'=U-B[/tex]

[tex]B'=\{a, b, c, d, e, f, g, h\}-\{a,d,e\}[/tex]

22.5 i’m pretty positive

Answer:

22.5

Step-by-step explanation:

Everything equals 180. This means that the 90 degree angle creates half of that would mean that everything on the right side of the 90 degree angle, also has to equal 90 degrees. X=22.5 because you have to combine like terms meaning x + 3x = 90- 4x=90. Divide by 4 on both sides of the equals sign. Plug that into a calculator and you get 22.5 Since it is only asking for the singular x, you don't have to solve for 3x. (It would be 67.5)

8. A cone shaped paper cup has a radius of 1.5 inches and a height of 3 inches. What is the volume of the cup?​

Answers

Answer:

[tex]V=7.06\ \text{inches}^3[/tex]

Step-by-step explanation:

Given hat,

The radius of cone shaped paper cup, r = 1.5 inches

The height of cone shaped paper cup, h = 3 inches

We need to find the volume of the cup. For a cone shaped, the volume is given by :

[tex]V=\dfrac{1}{3}\pi r^2 h[/tex]

Putting all the values in the above formula.

[tex]V=\dfrac{1}{3}\pi \times (1.5)^2 \times 3\\\\V=7.06\ \text{inches}^3[/tex]

So, the volume of the cup is [tex]7.06\ \text{inches}^3[/tex].

Uncle John has 32 lemon trees and 28 lime trees to plant on his grove. He would like to plant the trees in rows where each row has the same number of lemon trees and each row has the same number of lime trees. What is the greatest number of rows Uncle John can plant?

Answers

Answer:

The greatest number of rows is 10.

To find this you can do 32 plus 28 which equals 60 then you know 60 divided by 10 is 6 so you could have six rows and six columns or 10 rows and six columns and 10 is greater than six.

So, the greatest number of rows you can have is 10.

my first expression answer is y=5 -2x How do I plug it into x-y=1 ?? The Y

1. x-5-2x=1 OR

2. x+5-2x=1

Answers

Answer:

All you need to do is make sure the first expression is solved for y (which it is), and then substitute it into the second expression in place of any occurrences of y:

given the second expression:

x - y = 1

We'll replace y with it's value in the first expression:

x - (y) = 1

x - (5 - 2x) = 1

Now we can expand the resulting equation:

x - 5 + 2x = 1

So neither of the answers provided are correct.

You can then solve for x:

x - 5 + 2x = 1

x - 5 + 5 + 2x = 1 + 5

x + 2x = 6

3x = 6

3x/3 = 6/3

x = 2

After that, you can find y by plugging x into either of the two original equations:

y = 5 - 2x

y = 5 - 2(2)

y = 5 - 4

y = 1

a. This low correlation of .013 indicates there is no relationship.
b. There is no linear relationship but there may be a nonlinear relationship.
c. This correlation indicates there is some type of linear relationship.

The answer is "Option b".

Step-by-step explanation:

In this question, the value of the correlation coefficient is 0.013 from the given information. It is the equation, which realized the indeed closer their correlation coefficient is to -1 or 1, the greater the positive correlation, although in this case, the value of the correlation coefficient is 0.013, close to "0".
