Explain how to decide when a normal distribution can be used to approximate a binomial distribution.
A normal distribution can be used to approximate a binomial distribution when n* p and n * q are greater than 5.
What is a normal distribution?A probability distribution that is symmetric about the mean is the normal distribution, sometimes referred to as the Gaussian distribution. It demonstrates that data that are close to the mean occur more frequently than data that are far from the mean.
A probability bell curve is more properly described as the normal distribution.
The mean and standard deviation of a normal distribution are 0 and 1, respectively. It has a kurtosis of 3 and zero skew.
Not all symmetrical distributions are normal, but all normal distributions are symmetrical.
Natural occurrences frequently resemble the usual distribution.
However, most price distributions in finance are not exactly normal distributions.

The data point that has strongest association of its two factors will be:
Those who like hamburger and burrito = 39/134 = 0.29
Those who like hamburger and not burrito = 95/134 = 0.71
Those who like burrito but not hamburger = 38/71 = 0.53
Those who do not like hamburger or burrito = 33/71 = 0.47.
Therefore, the data point that has strongest association of its two factors will be those who like hamburgers but not burritos.

Find the area of each rhombus.
PLS HELP!! Geometry!!!!
Answer:
A) 384
B) 576
Step-by-step explanation:
the area of a rhombus is
pq/2
First Rhombus
we have p but to find q we can cut the triangle in half to form a right triangle, that allows us to use the Pythagorean theorem
20² = 12² + b²
400 - 144 = b²
b² = 256
b = 16
since the height (b) is half the rhombus, we double it to get q
p = 24
q = 32
a = [tex]\frac{24*32}{2}[/tex]
a = 384
Second Rhombus
Since rhombuses are parallelograms, we can use its area formula (b)(h)
a = (24)(24)
a = 576

Number of sodas/Total cost
pick a number
24/18 = 4/3
Answer:
4/3
Step-by-step explanation:
Rate of change is also known as slope.
To find slope, you have to find the change in y divided by the change in x.
y2-y1 / x2-x1
The variable y in this situation is the number of sodas.
The variable x in this situation is the total cost.
