False
True
True
True

Step-by-step explanation:

An easy way to tell if the equation is true is to multiply it by the product of the denominators (cross multiply).

7×7 ≠ 12×4 . . . . proportion is False

9×8 = 36×2 . . . . proportion is True

8×9 = 24×3 . . . . proportion is True

5×104 = 8×65 . . . . proportion is True

Please write a equation for this table

Hitman42 [59]

Answer:

y = 5x +2

Step-by-step explanation:

The point (0, 2) tells us the y-intercept is 2.

If we translate the table down 2 units by subtracting 2 from every y-value, it becomes ...

6, 30

-2, -10

0, 0

10, 50

We notice these values are all related by a factor of 5 (they are proportional). That means the equation will be a straight line with slope 5 and y-intercept 2.

y = 5x +2

20POINTS IF YOU CAN HELP

Alenkinab [10]

we know that

there are two types of probability

(1) Theoretical probability:

Theoretical probability is used to find the chance of a particular outcome

For example: tossing a coin

rolling a die

(2) Experimental probability:

Experimental probability is calculated using data from experiments

For example: A fair coin is tossed 25 times

a die is rolled 10 times

Here , we are given

a bag contains 9 tiles numbered 1-9

and probability of choosing 4 is p(4)

that is

$p(4)=\frac{1}{9}$

Since, we are finding a chance to get card number 4 out of 9 cards

so, it is theoretical probability.........Answer

How could the sum of cubes formula be use to factor x^3y^3+34

professor190 [17]

Sum of cubes: a^3 + b^3 = (a+b)(a^2 - ab + b^2)

Sum of cubes: x^3*y^3 + 34, or (xy)^3 + (∛34)^3

This factors into (xy + ∛34)*( [xy]^2 - xy∛34 + (∛34)^2 )
