When you simply the expression it’s 16
Gotta be 40, since the sample probability of choosing a pink was 2/5, apply that to 100 chips and you get a predicted 40 pink chips in the bag
Before we figure out how many customers you will need to talk per day to reach your goal, let's calculate what is 20% of how many customers you normally talk to a day.
current no. = 8
goal = 8 + 20%
20% = 8 x 0.20
(a percent is really just a fraction with the percent number over 100)
20% = 1.60
goal = 8 + 1.60
goal = 9.60
However, there is no such thing as .60 of a person so we will have to round up. You will need to talk to 10 customers per day.
Answer:
Exponential decay.
Step-by-step explanation:
The magnitude of the base (also known as the "common factor") tells us whether a given exponential equation represents growth or decay.
Standard equation for expo. growth: y = 3(b)^x, where b is the base.
If 0<b<1, we have expo. decay; if 1<b, we have expo. growth.
Thus, y = 3(0.5)^x represents expo. decay.
A generic point on the graph of the curve has coordinates

The derivative gives us the slope of the tangent line at a given point:

Let k be a generic x-coordinate. The tangent line to the curve at this point will pass through
and have slope 
So, we can write its equation using the point-slope formula: a line with slope m passing through
has equation

In this case,
and
, so the equation becomes

We can rewrite the equation as follows:

We know that this function must give 0 when evaluated at x=0:

This equation has no real solution, so the problem looks impossible.
