Answer:
Rhombus
Step-by-step explanation:
The given points are A(−5, 6), B(−1, 8), C(3, 6), D(−1, 4).
We use the distance formula to find the length of AB.
The length of AD is
The length of BC is:
The length of CD is
Since all sides are congruent the quadrilateral could be a rhombus or a square.
Slope of AB
Slope of BC
Since the slopes of the adjacent sides are not negative reciprocals of each other, the quadrilateral cannot be a square. It is a rhombus
Answer:
Y=X+74
Step-by-step explanation:
75=m+b......*
76=2m+b.........**,b=76-2m
then substitute b=76-2m
on the first equation
75=m+76-2m
m=1
b=74
Y=X+74 is the answer
Using the binomial distribution, it is found that there is a 0.0116 = 1.16% probability that exactly 4 out of the first 14 customers buy a magazine.
<h3>What is the binomial distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- 7% of his customers buy a magazine, hence p = 0.07.
- A sample of 14 customers is taken, hence n = 14.
The probability that exactly 4 out of the first 14 customers buy a magazine is P(X = 4), hence:
0.0116 = 1.16% probability that exactly 4 out of the first 14 customers buy a magazine.
