So you have a 50% chance to have a boy vs a girl (1/2). If you want 3 children, that would be 1/3*1/2= 1/6 or 16.67% chance
Answer:
First answer at the top.
Step-by-step explanation:
Answer:x=1
Step-by-step explanation:
(2x-5)/(x-2) - 2=3/(x+2)
(2x-5-2(x-2))/(x-2)=3/(x+2)
(2x-5-2x+4)/(x-2)=3/(x+2)
-1/(x-2)=3/(x+2)
Cross multiply
-1(x+2)=3(x-2)
Open brackets
-x-2=3x-6
Collect like terms
3x+x=6-2
4x=4
Divide both sides by 4
4x/4=4/4
x=1
We have been given that Circle C has diameter AE with a length of 2 cm, and a central angle with the measure . We are asked to find the length of arc DE.
We will use arc length formula to solve our given problem.
, where,
= Arc length,
= Central angle in degrees.
r = radius of circle.
Since AE is diameter, so radius will be half of AE.
Upon rounding to nearest tenth, we will get:
Therefore, the length of arc DE is approximately 0.7 cm.
Answer:
Answer is X = 100
Step-by-step explanation:
X+80=180 (co interior angle)
x=180-80
x=100
