A, X=6(x-2) as his age take away 2 (his age two years ago) then multiplied by 6 will equal his current age.
Answer:
![P(G\ then\ R)=0.045](https://tex.z-dn.net/?f=P%28G%5C%20then%5C%20R%29%3D0.045)
Step-by-step explanation:
From the question we are told that:
Percentage of Green beads ![P_g=18](https://tex.z-dn.net/?f=P_g%3D18)
Percentage of Red beads ![P_r=18](https://tex.z-dn.net/?f=P_r%3D18)
Percentage of Purple beads ![P_p=18](https://tex.z-dn.net/?f=P_p%3D18)
Therefore
Probability of choosing a Green bead is
![P(G)=0.18](https://tex.z-dn.net/?f=P%28G%29%3D0.18)
Probability of choosing a Red bead is
![P(R)=0.25](https://tex.z-dn.net/?f=P%28R%29%3D0.25)
Generally the equation for choosing a green bead then a red bead is mathematically given by
Since Outcomes are independent
![P(G\ then\ R)=0.18*0.25](https://tex.z-dn.net/?f=P%28G%5C%20then%5C%20R%29%3D0.18%2A0.25)
![P(G\ then\ R)=0.045](https://tex.z-dn.net/?f=P%28G%5C%20then%5C%20R%29%3D0.045)

Answer:
Step-by-step explanation:
Ryan works mowing lawns and babysitting. He earns $8.20 an hour for mowing and $7.70 an hour for babysitting. Therefore, the expression for the total amount that he would earn if he mows lawns for x hours and babysits for y hours would be
8.2x + 7.7y
Therefore, the amount that he would earn for 3 hours of mowing and 7hours of babysitting is
(8.2 × 3) + (7.7 × 7)
= 24.8 + 53.9
= $78.7
