Formula for an is 3n - 11
Step-by-step explanation:
- Step 1: Equation for a(n) = a + (n - 1)d where a = - 8, d = common difference = a2 - a1 = -5 - -8 = 3
⇒ a(n) = -8 + (n - 1)3 = - 8 + 3n - 3 = 3n - 11
Answer:
y=-1/2x+1
Step-by-step explanation:
b in the equation can be anything, as long as the equation has the same slope it will be parallel
From the question we are told that:
Total Sample size n=500
Dan's mean \=x_D= 3hr
Bret's mean \=x_D= 4hr
Generally, the Total hours spent doing leisure and sports activities is mathematically given by
For Sample A
For Sample B
Therefore
Average Time spent doing leisure and sports activities by an American Adult
For Sample A
For Sample B
Therefore

The formula for the surface area of rectangular prism is:
Let's break down our variables.
L = 12mm
W = 6mm
H = 7mm + 2mm = 9mm
Now we substitute our values in the formula:
