[tex]\boxed{\boxed{\pink{\bf \leadsto Perimeter\ of \ cross\ shaped \ pattern \ is \ 128cm. }}} [/tex]

Given that a cross shaped pattern is made by arranging four identical rectangles around the side of the square . The area of square is 64cm².

So , let's find the side of the square :-

[tex]\bf\implies\orange{Area_{square}=(side)^2}\\\\\bf\implies a\times a = 64cm^2\:\:\bigg\lgroup \red{\sf Assuming \ side \ to \ be \ a }\bigg\rgroup \\\\\bf\implies a^2 = 64cm^2 \\\\\bf\implies a=\sqrt{64cm^2} \\\\\implies\boxed{\purple{\bf a = 8cm }}[/tex]

Hence the side of square is 8cm .

Now , breadth of rectangle will be 8cm.

Now its given that the area of rectangle is 1½ times the area of square. So ,

[tex]\bf\implies Area_{rec.} = \dfrac{3}{2} \times Area_{square} \\\\\bf\implies Area_{rec.} = \dfrac{3}{2} \times 64 cm^2 \\\\\bf\implies \boxed{\red{\bf Area_{rectangle}= 96cm^2}}[/tex]

Hence side will be :-

[tex]\bf\implies lenght \times breadth = 96cm^2\\\\\bf\implies 8cm \times l = 96cm^2\\\\\bf\implies l =\dfrac{96cm^2}{8cm}\\\\\bf\implies \boxed{\red{\bf lenght = 12cm }}[/tex]

Hence the lenght of rectange is 12cm .

Now , the perimeter of the given figure will be ,

[tex]\bf\implies Perimeter_{cross} = 8(lenght) + 4(breadth) \\\\\bf\implies Perimeter_{cross} = 8\times 12cm + 4\times 8cm \\\\\bf\implies Perimeter_{cross} = 96cm + 32cm \\\\\bf\implies \boxed{\red{\bf Perimeter_{cross} = 128cm }}[/tex]

Answer:

-43

Step-by-step explanation:

The sum of the expression (3m+2n-6) and (-4-6m+7n) when m = 5 and n = -2 is -43.

An algebraic expression consists of unknown variables, numbers and arithmetic operators.

Given are two expressions, (3m+2n-6) and (-4-6m+7n)

Putting m = 5 and n = -2, we get,

(3m+2n-6) = 3x5-2x2-6 = 15-4-6 = 15-10 = 5

(-4-6m+7n) = -4-6x5-7x2 = -4-30-14 = -30-18 = -48

(3m+2n-6) + (-4-6m+7n) = -48+5 = -43

Hence, The sum of the expression (3m+2n-6) and (-4-6m+7n) when m = 5 and n = -2 is -43.

The choice that best describes the center of the data is the median.

Description of median

Median is a measure of central tendency. Median can be defined as the number that occurs in the center of a set of numbers that are arranged either in ascending or descending order.

For example, the median in these set of numbers; 100, 150, 200, 220, 250 is 200. This is because 200 is at the center of the data.

ANSWER: 1/6

Step-by-step explanation:

A fairly basic and fundamental problem in Probability, but still worth doing as an example of good mathematics.

Assumptions

The number cube is fair, that is not biased in any manner.

Key Points to Note.

Each roll of the number cube is an Independant Event, that is the outcome of any toss has no impact whatsoever on the outcome of any other toss.

The Probability of NOT achieving a specific outcome is equivalent TO ACHIEVING all other outcomes.

The Probability of achieving two sequential outcomes, is the Probability of achieving the first outcome multiplied by the Probability of achieving the second.

Analysis

What is the probability of rolling a 3 on a 6-sided number cube and then NOT rolling a 3 on a 6-sided number cube?

There are 6 sides on the number cube, each with an equal probability of being a specific outcome.

Therefore the Probability of a 3 as the outcome, is ( 1/6 ).

What is the probability of NOT rolling a 3 on a 6-sided number cube?

The Probability of NOT rolling a 3, is the same as either 1 - Probability (3) or Probability (1, 2, 4, 5, 6), which is equivalent to ( 5/6 )

Sequential Probabilities.

What is the probability of rolling a 3 on a 6-sided number cube AND THEN NOT rolling a 3 on a 6-sided number cube?

P( 3 ) then P( Not a 3 ) = ( 1/6 ) * ( 5/6 ) which equals ( 5/36 )

A Further Point to Note

Because the two rolls of the number cube are independant, the final probability is independant of the order of which outcome is first sought.
