<u>Answer:</u>

Z = "results of flipping two coins"

<u>Step-by-step explanation:</u>

A discrete variable is one which can take only certain values and usually represents values that are counted. The result of flipping two coins can only take a certain number of values of heads or tails (1 head and 1 tail, two heads, or two tails); therefore it is a discrete variable.

A continuous variable is one which can take any value, and usually represents values that are measured. The rest of the options provided (W, X, and Y) are all measurements, and are therefore continuous, not discrete.

Also, among the options presented, option Z is the only one which is "random".

What is the product of (7x+3)^2
Natali [406]

Answer:

49x² + 42x + 9

Step-by-step explanation:

Given

(7x + 3)²

= (7x + 3)(7x + 3)

Each term in the second factor is multiplied by each term in the first factor, that is

7x(7x + 3) + 3(7x + 3) ← distribute both parenthesis

= 49x² + 21x + 21x + 9 ← collect like terms

= 49x² + 42x + 9

What is the difference written in scientific notation? 0.00067 - 2.3 x 10^5
shepuryov [24]
0.00067=67X10^5 so

67X10^5-2.3X10^5

64.7X10^5 which can be expressed as:

6.47X10^6

(not sure if it matters to you or not, but technically we only had two significant figures so it should be rounded to 6.5X10^6)

What 2 numbers that are the same multiply to be 36 and add up to be 15?
marysya [2.9K]
The only way to have two numbers that are the same and add up to be 15
is if they're both 7.5 , but those don't multiply to be 36.  So I guess there's
no answer that satisfies all the conditions of this question.

Dave has 10 poker chips, 6 of which are red and the other 4 of which are white. Dave likes to stack his chips and flip them over
Marina86 [1]

The number of 10 chips stacks that Dave can make if two stacks are not considered distinct is 110.

The solution

To get the symmetric stacks, one has to subtract the symmetric stacks to know the ones that are asymmetric.

The symmetric are flipped. Given that they are double counted what we have to do is to divide through by 2.

6/2 = 3

10/2 = 5

4/2 = 2

1/2(10C6) - (5C3) + (5C3)

0.5(210-10+10)

= 110
