Step-by-step explanation:
Answer:
Yellow.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes. Experimental probability is found taking into account previous experiments.
In this question:
6 + 5 + 4 + 10 = 25 total marbles.
The experimental probabilities are:
6/25 probability it is red.
5/25 = 1/5 probability it is yellow. Thus, the answer is yellow.
4/25 probability it is blue.
10/25 = 2/5 probability it is green.
Answer:
or 21.2132
Step-by-step explanation:
<em> </em>(root of a product is equal to the product of the roots of each factor)
(simplify)
or ≈ 21.2132
Answer:
Elgas is 9 years old.
Step-by-step explanation:
Alvin: 3 x Elgas
36: Alvin + Elgas
36 / 4 : 9
Elgas: 9
Alvin: 27
To check: 27 + 9= 36
This question can be solved through trial and error method looking at the closest possibilities.
p(x)= (x^2 + x+2)- ( 2x^2 +2(-2x -4))
= (x^2 + x+2) - (2x^2 -4x -8) ( simplify inner brackets)
if x+2=0, x=(-2) ; p(x)= (-2)
( (-2)^2 + (-2)+2 ) - (2X(-2)^2 - 4X(-2) - 8) ( solve brackets using BODMAS rule)
(4+0) - (2X2 + 8-8)
4-4
= 0
therefore x= (-2)
