Answer:
This is the same as writing (n-m)/n
Don't forget about the parenthesis if you go with the second option.
==================================================
Explanation:
The probability that she wins is m/n, where m,n are placeholders for positive whole numbers.
For instance, m = 2 and n = 5 leads to m/n = 2/5. This would mean that out of n = 5 chances, she wins m = 2 times.
The probability of her not winning is 1 - (m/n). We subtract the probability of winning from 1 to get the probability of losing.
We could leave the answer like this, but your teacher says that the answer must be "in the form of a combined single fraction".
Doing a bit of algebra would have these steps
and now the expression is one single fraction.
Answer:
79
Step-by-step explanation:
We require his total score after 5 games
average = , hence
= 91 ( multiply both sides by 5 )
total = 5 × 91 = 455
let his score in the sixth game be x, then
= 89 ( multiply both sides by 6 )
455 + x = 534 ( subtract 455 from both sides )
x = 534 - 455 = 79
his score in the sixth game was 79
Answer:
x<55
Step-by-step explanation:
Answer:
y = x +
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (- 8, 5) and (x₂, y₂ ) = (- 2, 9)
m = = = , thus
y = x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 2, 9 ), then
9 = - + c ⇒ c = 9 + =
y = x + ← equation of line
