We notice there are 4B and 4G (shown in the photo)
P(picking 1st a Green) = 4/8 (having picked a green -and not replacing it- the remaining number of marbles is 3G + 4B)
P(picking 2nd a Green) =3/7
P(picking 1st green AND picking 2nd Green )=(4/8) x (3/7) = 12/56≈ 0.21=21%
statement 4/14=6/21=8/28 is true
Step-by-step explanation:
When dividing the fraction they all equal to 0.285714
Answer:
16.5 =x
Step-by-step explanation:
Since this is a right triangle, we can us trig functions
tan theta = opp side / adjacent
tan 70 = x /6
Multiply each side by 6
6 tan 70 = x
16.48486452 =x
To the nearest tenth
16.5 =x
