Answer:
P(red) = .3
P(yellow) = .3
75 cubes in the box
Step-by-step explanation:
The probability has to add to 1
Since the number of red cubes equals the number of yellow cubes the probability has to be the same
.4 + x+x = 1
.4 +2x = 1
2x = 1-.4
2x = .6
Divide by 2
x = .6/2
x = .3
P(red) = .3
P(yellow) = .3
We know that
P(blue) = .4 = number of blue cubes/ total number of cubes
.4 = 30/total
total = 30/.4
total = 75
The answer would be 24/5, 4 4/5, or 4.8
The equation in standard form is: y=5x+3
Answer:
(2,1,0)
Step-by-step explanation:
3x+3y+6z=9
3(2)+3(1)+6(0)=9
6+3+0=9
6+3=9
9=9
x+3y+2z=5
x(2)+3(1)+2(0)=5
2+3+0=5
2+3=5
5=5
3x+12y+12z=18
3(2)+12(1)+12(0)=18
6+12+0=18
6+12=18
18=18
Answer:
25/28
Step-by-step explanation:
1 1/4=5/4
1 2/5=7/5
------------
(5/4)/(7/5)
(5/4)(5/7)
25/28
