Answer:
x = 77.5
Step-by-step explanation:
1. Use cross-multiplication to find x.
2. Divide and round.
x ≈ 77.5
Probability of raining=0.45
Probability of not raining=1-0.45=0.55
The expected earning will be given by:
E(x)=240(0.55)+320(0.45)
E(x)=132+144
E(x)=276
Answer: $276
Answer:
x < 5
Step-by-step explanation:
What 5 > x means is that the variable x takes values less than 5, we can notice that because the narrow part of the symbol is pointing towards x, which means x is smaller than 5.
Analyzing the options:
- x> 5 this tells us that x takes values greater than 5, which in fact is the opposite of what we are looking for.
- 5 <x this also tells us that x takes values greater than 5, not what we are looking for.
- x < 5 this option does represent the same as 5 > x because in both the narrow part of the symbol points to x, indicating that x is smaller than 5, therefore this is the correct option
