im not for sure but I think the answer is 9! my reasoning is below,,
Step-by-step explanation:
![\frac{49}{7} = \frac{63}{x}](https://tex.z-dn.net/?f=%20%5Cfrac%7B49%7D%7B7%7D%20%20%3D%20%20%5Cfrac%7B63%7D%7Bx%7D%20)
do the crossing method and it would result in this
(49×x) = (63×7)
after simplifying both sides
49x = 441
divide both sides by 49 and the result will be
x = 9 !!
Answer:
3x+2
Step-by-step explanation:
The polygon is regular ,<em> </em>so all the sides would be equal.
Thus all sides measure same as <u>3x</u><u>+</u><u>2</u>

Answer:
D. 0.002
Step-by-step explanation:
Given;
total number of sample, N = 500 elements
50 elements are to be drawn from this sample.
The probability of the first selection, out of the 50 elements to be drawn will be = 1 / total number of sample
The probability of the first selection = 1 / 500
The probability of the first selection = 0.002
Therefore, on the first selection, the probability of an element being selected is 0.002
The correct option is "D. 0.002"
