Answer:
A and B are the answers on Edge.
Step-by-step explanation:
<span>it all looks confusing when we try to juggle with all those numbers in the head. The problem can be solved systematically by constructing a contingency table.
</span>role/gender B G total
speaking...... 4 4 8
<span> silent............ 4 8 12
total............. 8 12 20
</span>Probability of a child having a speaking part is therefore
(4+4)/20=8/20=2/5
a. 2/5
Answer:
345.2
Step-by-step explanation:
1: Move 3.452 to the end of the equation
(3.452 × 100) -> (3.452 × 100 = 3.452)
2: Since 100 has 2 zeros, move the decimal point 2 places to the right.
(3.452 × 100 = 3.452) -> (345.2)
Hope this helps!
(x,y)
y=mx+b
m=slope
b=yintercept
slope=7/10
one point is (1,2) or x=1, then y=2
find b
y=7/10x+b
2=7/10(1)+b
2=7/10+b
minus 7/10 both sides
1 and 3/10=b
13/10=b
y=7/10x+13/10
input values for x and get values for y
one point is (0,13/10)
