Answer:
5:9
Step-by-step explanation:
It's just a way to set up ratios. Whichever number is said first gets put down first, then the number after gets put after.
So, 5:9
Or, you could write it as 5 footballs to 9 baseballs.
This is just my simple understanding of what you're asking since you asked what the ratio is.
Hope I helped!
Solution:
Given expression is 
To find the inverse of y.
⇒
Do cross multiplication.
⇒ y = –6 × 3
⇒ y = –18
Inverse of y means reverse the function.
We know that inverse of y is 
.
⇒ 
Hence, inverse of y is 
Answer:
y = -x
Step-by-step explanation:
The line has a slope of -1 and it passes through point (0,0)
Taking another point (x,y) on the line;
Slope = change in y ÷ change in x
For our case; slope = 
Cross multiplying this gives;
y = -x
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".
