Which monomials are perfect squares? Check all that apply. 6x2 9x8 16x9 25x12 36x16
Answers
Answer:
Step-by-step explanation:
Let's check all the monomials
Here 6 is not square digit, hence this monomial is not a perfect square.
Here 9 is a square digit and the power of x i.e. 8 is multiple of 2 .
Hence, this monomial is a perfect square.
Here 16 is a square digit but the power of x i.e.9 is not multiple of 2 .
Hence, this monomial is not a perfect square.
Here 25 is a square digit and the power of x i.e. 12 is multiple of 2 .
Hence, this monomial is a perfect square.
Here 36 is a square digit and the power of x i.e.16 is multiple of 2 .
Hence, this monomial is a perfect square.

x+y= 105 => 4x+4y= 4*105= 420
4x+2y =360
-----------------------------------------
4y-2y = 420-360= 60
2y = 60 => y= 60:2=30 => x= 105-30=75
Verify 4*75+2*30= 300 + 60 = 360
4x+2y=360
Solve the above equation for x and y and that will give you the number of tickets sold.

The correct option is Option D: Line AC and RS are skew lines.
What is the line?
A line is defined as set of points that extends infinitely in either direction. A line is the shortest distance between any two points.
What are skew lines?
Skew lines are two lines that never intersect and are not parallel also. Hence we can say that the two lines can not exist in the same plane.
From the figure it is clear that
Line AC and RS are in different planes and they are also not intersecting each other, hence according to the definition of skew lines, they are skew lines.

347. How many tractors were sold in 2008?
Answers
Answer:
715 garden tractors.
Step-by-step explanation:
We have been given that a company’s sales of garden tractors increased about 106% from 2007 to 2008. The number of tractors sold in 2007 was 347.
So the number of tractors sold during 2008 will be 347 plus 106% of 347.
Therefore, 715 garden tractors were sold in 2008.

Step-by-step explanation:
They are independent because P(X) + P(Y) = P(X and Y).
They are dependent because P(X) · P(Y) = P(X and Y).
They are dependent because P(X) + P(Y) = P(X and Y).
Answers
Answer:
They are independent because P(X) · P(Y) = P(X and Y).
Step-by-step explanation:
Two events are independent if the occurrence of one event does not affect the probability of the occurrence of the other event. This means that the probability of both events happening is equal to the product of the probabilities of each event happening individually.
In the given situation, we have:
P(X) = 1/2
P(Y) = 1/2
P(X and Y) = 1/4
If we calculate the product of P(X) and P(Y), we get:
P(X) · P(Y) = 1/2 · 1/2 = 1/4
This is equal to P(X and Y), which means that the events X and Y are independent.
P(X) + P(Y) = P(X and Y) is not a necessary condition for independence. For example, the events of flipping a coin and rolling a die are independent, but P(X) + P(Y) ≠ P(X and Y).
Therefore, the best description of the events is that they are independent because P(X) · P(Y) = P(X and Y).
