Which of the following represents x = 1/3y written in general form?
1/3x - y = 0
3x - y = 0
x - 1/3y = 0

Answers

$x= (1)/(3)y$ put all numbers on the left
$x- (1)/(3)y=0$
third equation is the answer
$x- (1)/(3)y=0$ multiply by 3
3x-y=0

$x=(1)/(3)y\ \ \ \ \ \ \ \ \ |substract\ (1)/(3)y\ from\ both\ sides\n\n\boxed{x-(1)/(3)y=0}\n\nx-(1)/(3)y=0\ \ \ \ |multiply\ both\ sides\ by\ 3\n\n\boxed{3x-y=0}$

In Mr. Smith's 7th Hourclass there are 16 boys and
7 girls. What is the
probability of randomly
selecting a boy?

Answers

binomial(16 + 7, 16) 2^(-(16 + 7)) = ((16 + 7)!)/(16! 7! 2^(16 + 7)) = 245157/8388608 ≈ 0.02922 ≈ 1/34.22

(assuming children are independent and male and female are equally likely)

| probability

less than 16 boys | 0.9534

16 or less boys | 0.9827

more than 16 boys | 0.01734

16 or more boys | 0.04657

fraction of boys | 16/(16 + 7) ≈ 0.695652

fraction of girls | 7/(16 + 7) ≈ 0.304348

expected value | 11.5

standard deviation | 2.398

variance | 5.75

Solve for x: x − 2 > 2x + 12.x > 14

x < 14

x > −14

x < −14

Answers

The required solution to the given inequality is x < -14. which is the correct answer would be an option (D).

What is inequality?

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

To solve the inequality x − 2 > 2x + 12, we first need to isolate the x-term on one side of the inequality. We can do this by adding 2 to both sides, which gives us:

x − 2 + 2 > 2x + 12 + 2

x > 2x + 14

Then, we can subtract 2x from both sides to isolate the x-term on the left-hand side:

x - 2x > 2x + 14 - 2x

-x > 14

Finally, we can divide both sides by -1 to get x < -14.

Therefore, the required solution to the given inequality is x < -14.
