Hello there!
First of all, I like your profile picture!
1) There's a lot of different methods for solving a system of equation. But here are my three favorite.
- Graphing
- Substitution (Which I preferred to use and I think it is easier).
- Elimination
2) When solving a system of equations, you can get;
- One solution
- No solution
- Infinite number of solution
3) The graphing method help solving a system of equation by knowing that the solution to a system of equations is the point of intersection of the two lines.
I hope this answer helps. As always, it is my pleasure helping student like you!
Answer:
1/5
Step-by-step explanation:
change of y over change of x will get you 1.5/7.5 which is 0.2 or 1/5
Z= 138/625 or in decimal form it’s 0.2208
Answer:
probability that his sample will contain at least one damaged apple (P) = 0.7215
Step-by-step explanation:
Given:
Probability of damaged apples (p) = 12% = 0.12
number of samples (n) = 10
Consider,
x- number of apples damaged.
Using Binomial distribution formula:
P(x) = 
To find the probability that his sample will contain at least one damaged apple:
P(x≥1) = 1 - P(x<1)
= 1 - P(x=0)
= 1 - 
P(x≥1) = 0.7215
