Answer:

[tex]3n \geq n + 1[/tex]

Step-by-step explanation:

3 times a number = 3n

is at least = greater than or equal to, so [tex]\geq[/tex]

that number plus 1 = n + 1

the same variable is used (n) because the number is supposed to be the same.

Put that all together and u get [tex]3n \geq n + 1[/tex]

hope this helps!

Answer:

(a)

[tex]S = \{(1,H),(2,H),(3,H),(4,H),(5,H),(6,H),(1,T),(2,T),(3,T),(4,T),(5,T),(6,T)\}[/tex]

(b)

[tex]P(A) = \frac{1}{6}[/tex]

Step-by-step explanation:

Given

The above sample space

A = Event of an occurrence of 3 or 4 then a head

(a): List out the sample space:

The rolls of the dice come first, followed by the toss of the coin.

So, the sample space are:

[tex]S = \{(1,H),(2,H),(3,H),(4,H),(5,H),(6,H),(1,T),(2,T),(3,T),(4,T),(5,T),(6,T)\}[/tex]

The number of the sample space is:

[tex]n(S) = 12[/tex]

(b): Find P(A)

First, we list out the outcomes of event A

[tex]A = \{(3,H),(4,H)\}[/tex]

The number of outcome is:

[tex]n(A) = 2[/tex]

The probability of A is then calculated as:

[tex]P(A) = \frac{n(A)}{n(S)}[/tex]

[tex]P(A) = \frac{2}{12}[/tex]

Simplify fraction

[tex]P(A) = \frac{1}{6}[/tex]

Answer:

t=2.25

Step-by-step explanation:

9 divided by 4 is 2.25

and 4 x 2.25 is 9

Answer t = 9/4

Divide both sides of the equation by the same term

9 = 4t

9/4=9/4

Answer:

A unit multiplier (or conversion factor) is a fraction with value 1 that we use to convert quantities. Because the value of every unit multiplier is 1, we can multiply any quantity by them, without changing their value. Principles behind the technique: ! We never change the value of a quantity if we multiply it by 1.

Answer: Yogi has 59 chairs.

Step-by-step explanation: For the question, it's a lot of guess an check. 10 is a good place to start. Times 10 by 8 and add 3. Then times 6 by 10 and add 17. Does it equal the same number? No. Is it close? Yes. So maybe try going up a few numbers or down a few. You'll eventually get 7 which when you multiple 7 by 8 and add 3 and multiple 6 by 10 and add 17, you'll get 59.

Answer:

Step-by-step explanation:

Answer:

If the minimum 13 chair were sold , then the minimum number of Table sold is 14

Step-by-step explanation:

Given as :

The cost of each chair = $ 200

The cost of each table = $ 600

The total number of furniture sold per day = 32

The minimum amount of selling per day = $ 12000

Let the total number of chair = C

The total number of table = T

So , according to question

C + T = 32         .......1

200 C + 600 T = 12000         .......2

Solving eq 1 and 2

200 C + 600 T = 12000

200 × ( C + T ) = 32 × 200

I.e 200 C + 200 T = 6400

or, ( 200 C + 600 T ) - ( 200 C + 200 T ) = 12,000 - 6400

Or, 400 T =  5600

∴  T =

I.e T = 14

Put The value of T in eq 2

So, 200 C + 600 × 14 = 12000

or , 200 C + 8400 = 12,000

Or, 200 C = 12000 - 8400

Or, 200 C = 3600

∴   C =

I.e C = 18

The number of chair sold is 18

If the number of chair sold is 13 ,

Then the min number of table sold = 200 × 18 + 600 T = 12000

i.e 600 T = 12000 - 3600

or, 600 T = 8400

∴   T =

I.e T = 14

Hence if the minimum 13 chair were sold , then the minimum number of Table sold is 14 . Answer

Hey I’m sorry I don’t actually know the answer to this I’m working on it rn but if u did find out the answer to this do u mind helping me. I’m sorry and thank uu. Like if there was a sample answer to that can u reply to me with it. I’m really struggling here any help would be greatly appreciated

Answer:

(-3,-1) -> (3,1)

Step-by-step explanation:

Reflection over the y-axis:

When we reflect a point (x,y) over the y-axis, it's y-coordinate is kept, while the x-coordinate changes signal. So

(3,-1) -> (-3,-1)

Clockwise rotation of 180º

Both coordinates of the point change signals. So

(-3,-1) -> (3,1)
