Y=5x-4 is linear
y=x/3 is linear
y=x^3+1/3 is non linear
Basically linear means it is a straight line when graphed. So anything with exponts is non linear by default among some other rules for determining linear or nonlinear Hope this helps! Please rate my answer and help me also! Thank YOU!!!!!:)
Your straight line is east-west
Using the hypergeometric distribution, it is found that there is a 0.7568 = 75.68% probability that neither can wiggle his or her ears.
The people are chosen from the sample without replacement, which is why the <u>hypergeometric distribution</u> is used to solve this question.
Hypergeometric distribution:
The parameters are:
- x is the number of successes.
- N is the size of the population.
- n is the size of the sample.
- k is the total number of desired outcomes.
In this problem:
- 1000 people means that

- 130 can wiggle their ears, thus

- Two are selected, thus
.
The probability that neither can wiggle his or her ears is P(X = 0), thus:


0.7568 = 75.68% probability that neither can wiggle his or her ears.

Answer:
15
Step-by-step explanation:
The given equation is


When we multiply we obtain the equations:


We add both equations to obtain:

Divide both sides by -7 to get:
