$55.00 and $25.00. You have an electric bill of $40.64, bill for postage

Answer:
2 cookies per dollar
Step-by-step explanation:
You can take any point on the line, turn it into a fraction and simplify.
For example: 4 cookies cost $2.
4 cookies per 2 dollar is 2 cookies per 1 dollar (divide by 2)
If you take another point, e.g., 14 cookies for 7 dollar, you'll be dividing by 7 to simplify and get the same answer.
Are you solving for x or solving for r
There are many ways you can write a ratio. They're all basically the same thing, though. 5:9, 5 to 9, and 5/9 (which is a fraction) are all just different ways to write ratios.
Answer:
0.0416
Step-by-step explanation:
Given :
Number of balls :
Pink = 8 ; black = 9
Total number of balls = 8+9 = 17
Choosing with replacement :
Probability = required outcome / Total possible outcomes
Required outcome = number of black balls
Total possible outcomes = total number of balls
P(black) = 9/17
Number of picks = 5
Hence, Probability that all 5 picks are black :
P(all black) = 9/17 * 9/17 * 9/17 * 9/17 * 9/17 = 0.0415879
= 0.0416
