Is this correct? Pls help within 10 minutes will mark brainliest

Answer:

the first answer is correct

the second answer is correct if they messed up on the question and meant to ask for the MAD of set B

I think the 3rd answer is incorrect (I got 1.09), so you might want to double-check your 3rd answer since it is asking for "times bigger", not how much bigger, which means how many times larger is the MAD of set A than that of set B and to find how many times bigger a number is than another number, you have to divide the first number by the second number.

Consider the sequence of steps to solve the equation:

marin [14]

Answer: B) Addition Property

Step-by-step explanation:

The Step 3 is: $3x-30=0$

The idea is to solve the equation, which means that you have to find the value of the variable $x$ .

As $3x-30$ is a subtraction, you need to add 30 to both sides of the equation to keep the equation balanced. This property is known as "Addition property of equality".

This property states that adding the same number to both sides of the equation, the equality does not change:

$a=b\\a+n=b+n$

Then, the Addition property of equality applied in Step 3, get you to Step 4:

$3x-30+(30)=0+(30)\\3x=30$

The value of ( sqrt 5 + sqrt 2 )( sqrt 5 - sqrt 2 )is: (a) 10 (b) 7 (c) 3 (d) sqrt(3

larisa86 [58]

Answer:

C) 3

Step-by-step explanation:

This is just a differences of squares:

$(a+b)(a-b)=(a^2-b^2)\\\\(\sqrt{5}+\sqrt{2})(\sqrt{5}-\sqrt{2})=(\sqrt{5}^2-\sqrt{2}^2)=5-2=3$
