Answer:5
Step-by-step explanation:y equal 5
A negative correlation is the relationship where an increase in one of the variable say x lead to a decrease in the other variable say y
In the question given, the variables are the number of workers in the x- axis and the hours of complete job in the y axis
Therefore option C is the only option where increase in the number of workers led to decrease in the hours of complete job
Hence the correct answer is option C
Answers:
a) 0.0625
b) 0.9375
==================================================
Work Shown:
The probability of landing on heads is 1/2 = 0.5 since both sides are equally likely to land on. Getting 4 heads in a row is (1/2)^4 = (0.5)^4 = 0.0625
The event of getting at least one tail is the complement of getting all four heads. This is because you either get all four heads or you get at least one tail. One or the other must happen. We subtract the result we got from 1 to get 1-0.0625 = 0.9375
You can think of it like this
P(getting all four heads) + P(getting at least one tail) = 1
The phrasing "at least one tail" means "one tail or more".
Answer:
the answer is probably 7/6
hope I am correct and if not I'm sorry
Solve for a.
y=2x/a+2b
Multiply both sides by a.
ay=2ab+2x
Add -2ab to both sides.
ay+−2ab=2ab+2x+−2ab
−2ab+ay=2x
Factor out variable a.
a(−2b+y)=2x
Divide both sides by -2b+y.
a(−2b+y) / −2b+y = 2x / −2b+y
a = 2x / −2b+y
