Minimum is 72

Maximum is 99

Q1 is 79.5

Q3 is 91.5

Median is 86.5

So the 5-number summary is {72, 79.5, 86.5, 91.5, 99}

Answer:

[tex]\mid x-6 \mid \geq 0[/tex]

Step-by-step explanation:

We have two options for x; it is either 6 or greater than 6:

If [tex]x=6\\[/tex], [tex]\mid x-6 \mid = \mid 6-6 \mid = \mid 0 \mid = 0\\[/tex].

If [tex]x > 6[/tex], [tex]\mid x-6 \mid > \mid 6-6 \mid[/tex] => [tex]\mid x-6 \mid > 0[/tex].

(for example, if [tex]x=7\\[/tex], [tex]\mid x-6 \mid = \mid 7-6 \mid = \mid 1 \mid = 1 > 0[/tex])

So, [tex]\mid x-6 \mid = 0[/tex] or [tex]\mid x-6 \mid > 0[/tex]; [tex]\mid x-6 \mid \geq 0[/tex].

Answer:

20y + 36

Step-by-step explanation:

Distribute the 4 to everything in the parenthesis (multiply).

4 x 5y = 20y

4 x 9 = 36

The solution of the expression 4(5y + 9 ) will be 20y + 36. The correct option is C.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The expression 4(5y+9) will be solved as below:-

E = 4 ( 5y+9 )

E = 20 y + 36

Therefore, the solution of the expression 4(5y + 9 ) will be 20y + 36. The correct option is C.

Step-by-step explanation:

24,000 = 24 thousands

30,000 = 30 thousands

3,000 = 3 thousands

2,4000 = 2.4 thousands

"x" years

24 + 3x = 30 + 2.4x

3x - 2.4x = 30 - 24

Answer:

2/5

Step-by-step explanation:

40% as a fraction is 4/10, when this fraction is simplified, it ends up as 2/5.

The  probability of the event that Diya's chance of wining the game is 0.4 or 2/5.

The probability of an event is the chance of happening that particular event.

Let, Diya can play a game 100 times.

Therefore, the number of times she can win the game is 40.

Let, D = the event that Diya is participating in the game.

Therefore, the probability that Diya will win the game is

[tex]= P(D)\\= \frac{40}{100}\\ = \frac{2}{5}\\ = 0.4[/tex]

Answer:

Step-by-step explanation:

You need to find the HCF of 36 and 90.

Prime factors of each:

HCF includes all prime factors of both numbers:

To find the least number,

Which is exactly divisible by 36 and 90. We have to find the HCF of 36 and 90.

→ 36 = 2 × 2 × 3 × 3

→ 90 = 2 × 3 × 3 × 5

Then the required HCF will be,

→ 2 × 2 × 3 × 3 × 5

→ 180 (HCF)

Thus, 180 is the least number which is exactly divisible by 36 and 90.

Of these choices, the best approximation is 1.05.

_____

A very good rational approximation of π is 355/113, which has a relative error of about 0.0000085%. This makes 355/339 a good approximation of π/3.

The relative error in the value n is ...

Answer:

y = 4sin((t+4π/3)/2) -2

Step-by-step explanation:

The generic form is   y = A·sin(B(t -C)) +D  

where  A is the amplitude

B is 2π/period

C is the phase shift

D is the vertical shift

You have   A = 4

period = 4π, so B = (2π)/(4π) = 1/2

C = -4π/3

D = -2

Putting these values into the above form gives:  

 y = 4sin((t+4π/3)/2) -2

Answer:

2. 6(6+12+3) = 6(6)+6(12) + 6(3) = 36+72 + 18  = 126 unit square

Area = 126 unit square.

and satisfies the 3 rectangle area. However can such amounts fit inside the rectangle as distributable?

We prove length of 21 units =

21-6 = 15 Units length and 15 - 12 = 3. Proves all 3 measures of length does fit within the length of 21 units length

Conclusion  Does satisfy as three length measures within one larger measure given for the large rectangle fit exact, to find area identical in totals.

Step-by-step explanation:

Proof area of 21 x 6 area rectangle = 126unit square

3 smaller rectangles made from same larger rectangle must = 126 unit square when all 3 smaller area are added together.

answer choices

1. 21(3+3) = 2(3)+21(3) only shows 2 rectangles area = 2 rectangles angle

Does not satisfy

2. 6(6+12+3) = 6(6)+6(12) + 6(3) = 36+72 + 18  = 126 unit square and satisfies the 3 rectangle area. However can such amounts fit inside the rectangle as distributable?

We prove length of 21 units =

21-6 = 15 Units length and 15 - 12 = 3. Proves it does fit within the width of 21 units length

Conclusion  Does satisfy as three length measures within one larger measure given for the large rectangle fit exact, to find area identical in totals.

3. 21 (3+2+3) = 21 (3) +21 (2)+21 (3) does not satisfy 6 units width as 3+2+3 = 8 and is too high a number. Does not satisfy.

4.6(10+10+11) = 6(10) + 6(10) + 6(11)  does not satisfy

The lengths of the three rectangles adds to 31 length as 10+10+11 = 31 instead of 21. Does not satisfy.
