The rate of change is -5/4
I find it best to use the Slope formula
M= y2-y1/x2-x1
So we to use need any 2 points on the graph (I used the first 2)
•(0,200) and (80,100)
Now we set up the problem 100-200/80-0
Then you’ll subtract and should get
-100/80
Now you’ll simplify and once you’re done simplifying your answer should be -5/4.
Here is my work. Hope this Helps!
Answer:
Inequality: 8p ≤ 50
Answer: p ≤ 6
Step-by-step explanation:
Step 1. Write an equation
$8 per person = 8p (where 8 is the cost per person and p is the number of people)
8p ≤ 50
Step 2. Solve
8p ≤ 50
÷8 ÷8
p ≤ 6.25 ≈ p ≤ 6 (your final answer is 6 because you cannot have 1/4 of a friend)
Total=14+20+16=50
P(blue)=20/50=2/5
so, answer=(2/5)*40=16
Answer:
One standard deviation above the mean means a z-score of 1.0. If we put this into the calculator as normalcdf(1,999) = .159
15.9 percent of the athletes would have a distance greater than 20.56 meters.
Now multiply the number of athletes by the percent.
.159 * 40 = 6.346 = about 6 athletes
c. about 6 athletes
It’s a 90 degree clockwise rotation as coordinates become (y,-x).
