Answer:
17/50
Step-by-step explanation:
Add all the jelly beans to get 100. There are 34 blue jelly beans. To find the probability of choosing a blue jelly bean, you make a fraction by making the fraction 34 over 100 (34/100). Simplify this to get 17/50.
Answer:
A
Step-by-step explanation:
Equations are values or a combination of terms the equal another combination of terms or values. Because A is the only one without an equals sign, we know that it is an expression.
Answer:
Step-by-step explanation:
A line is expressed as y=mx+b where m=slope and b=y intercept. As long as we have two points we can solve the equation of that line.
y=mx+b
For the top line I found two points (5,200) and (30,325)
m=(y2-y1)/(x2-x1)=(325-200)/(30-5)=125/25=5
y=5x+b, using point (5,200) we can solve for b
200=5(5)+b, b=200-25=175 so the line is
y=5x+175
For the bottom line we have points (5,50) and 10,100)
m=(100-50)/(10-5)=50/5=10
y=10x+b, using point (5,50) we have
50=10(5)+b, b=50-50=0 so
y=10x
