Solve the equation for both -1 and 1 first.
50(1/2)^-1 = 100
50(1/2)^1 = 25
Now subtract the two answers and divide by 2 ( -1 to 1 is 2)
75/2 = 37.5
Because the answer got smaller from -1 to 1, the change would be negative.
The rate of change would be -37.5
Answer:
5/12
Step-by-step explanation:
The whole book is 1.
So This will be your equation.
1/3 + 1/4 = 1
4/12 +3/12 = 1
7/12 = 1
Now you minus 7/12 from 1
1-7/12 is how much is left
12/12-7/12= 5/12

Step-by-step explanation:
<em>The question is incomplete as the solution to part A (or part A itself) is not given. To solve this, I will assume a value to the supposes solution to part A.</em>

From the question:
1 square foot is sold at $3.
This implies that:
p square foot will be sold at $3p.
So, total sales can be calculated using:

Now assume that p is 10 square feet (from part A).
The total will be:

Step-by-step explanation:
Answer:
This is a normal distribution and we can use the standard score to compute for probabilities. We compute the standard score of the given.
Explnation:
z = (x - mu)/sd
z = (2625 - 2600)/50 = 25/50 = 0.5.
Consulting the z-table, P(z <= 0.5) = 0.6915.
P(z > 0.5) = 1 - P(z <= 0.5) = 1 - 0.6915 = 0.3085.
I hope this helped! <3
