3 feet per second is equivalent to 2.04545 miles per hour
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:
Slope of Function B = 2 x Slope of Function A.
Step-by-step explanation:
The graph of Function B shows its slope to be 4 units up for 1 unit to the right, so 4.
The equation for Function A shows its slope to be the coefficient of x, so 2.
___
4 is 2 times 2, so ...
the slope of Function B is 2 times the slope of Function A.
Answer:

Step-by-step explanation:
.
m is the slope of the line. To find it we can do
which is the difference between the y-coordinates divided by the difference between the x-coordinates.
So:
. Now we have the slope, let's input a set of coordinates into the equation so that we can find the constant
.

- Re-arranging to get b
Now re-write the equation as we have the constants.
