Answer:
18
Step-by-step explanation:
The question is asking you to evaluate -4.5b, which is a simplified way of saying
-4.5 * b
Since we know that b = -4, we can insert that instead of b.
-4.5 * -4
The two negatives cancel each other out, so you're left with
4.5 * 4 = 18
(8c)^2+7c
(8c)^2=64c^2
so that..
64c^2+7c
factor out c
c(64c+7)
PART A:
Find the rate of change between 1980 and 1989
d for P₁ = 80 - 60
d for P₁ = 20
d for P₂ = 76 - 82
d for P₂ = -6
The rate of change in P₁ is 20 hundred per year. The rate of change in P₂ is -6 hundred per year.
PART B:
Find the rate of change between 1989 and 1996
d for P₁ = 100 - 80
d for P₁ = 20
d for P₂ = 70 - 76
d for P₂ = -6
The rate of change in P₁ is 20 hundred per year. The rate of change in P₂ is -6 hundred per year.
PART C:
Find the rate of change between 1980 and 1996
d for P₁ = 100 - 60
d for P₁ = 40
d for P₂ = 70 - 82
d for P₂ = -12
The rate of change in P₁ is 40 hundred per year. The rate of change in P₂ is -12 hundred per year.
Random number generator method evenly assigns the students to the two dormitories.
- Using a random number generator, assign each incoming female freshman a number, eliminating duplicate numbers.
- After each incoming female freshman is assigned a number, list the assigned numbers in ascending order.
- Assign the first 400 numbers on the ascending list to Williams dormitory, and assign the last 400 numbers on the ascending list to Hillside dormitory.
<h3>What is Random number generation?</h3>
- Random number generation is a process by which, often by means of a random number generator, a sequence of numbers or symbols that cannot be reasonably predicted better than by random chance is generated.
- Random numbers are useful for a variety of purposes, such as generating data encryption keys, simulating and modeling complex phenomena and for selecting random samples from larger data sets.
