Answer:
7x-48
Step-by-step explanation:
we want our equation to look something like this
y=mx+b
let's start by solving for m (the slope) using the slope formula
Which means, so far, our equation looks like this
y=7x+b
now we just need to solve for B
We can do this by plugging in a set of coordinates
-6=7*6+b
-6=42+b
-48=b
which means our equation is
7x-48
Answer:
Part 1) The maximum number of pounds of regular coffee that you can buy is 7.5 pounds.
Part 2)
Step-by-step explanation:
Part 1)
Let
x-----> the number of pounds of regular coffee
we know that
The inequality that represent the situation is
Solve for x
Divide by 2 both sides
The maximum number of pounds of regular coffee that you can buy is 7.5 pounds.
The solution of the inequality is the interval ------> (-∞,7.5]
but the number of pounds cannot be a negative number
therefore
The solution is the interval -----> [0,7.5]
see the attached figure
Part 2) we have
Adds m and n
Group terms that contain the same variable

The expected number of adults that believe ufos are watching earth is 4
<h3>How to determine the number of adults?</h3>
The given parameters are:
p = 48%
Sample size, n = 8
The expected number of adults that believe ufos are watching earth is calculated as:
E(x) = np
This gives
E(x) = 8 * 48%
Evaluate
E(x) = 3.84
Approximate
E(x) = 4
Hence, the expected number of adults that believe ufos are watching earth is 4
