Answer:
C. In y^2-y=6, 6 should have been subtracted on both sides first.
Step-by-step explanation:
It is a quadratic equation so you subtract the 6 and create
y^2-y-6=0
Then you factor it to:
(y-3)(y+2)=0
The solutions then are:
y-3=0, y=3 and y+2=0, y=-2
{-2,3}
Answer:
The first one can be anything as long as it has y=-7x
Second, the solution for the equations is (3 3/4, 0), I found that by using the elimination method. I don’t remember how to do the rest, I’m sorry
Using the binomial distribution, it is found that there is a 0.0231 = 2.31% probability that the first person to say yes will occur with the seventh customer.
For each person, there are only two possible outcomes, either they say yes, or they say no. The probability of a person saying yes is independent of any other person, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
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:
- The probability that the seventh person is the first to say yes is P(X = 0) when n = 6(first six say no) multiplied by 0.37(probability the seventh say yes).
- 37% say yes, hence
Then:
0.0231 = 2.31% probability that the first person to say yes will occur with the seventh customer.

Answer:
$22,500 worth of insurance would cost $164.70.
Step-by-step explanation:
Write and solve an equation of ratios:
$7.32 $1000
----------- = ---------------
x $22,500
Cross multiplying here yields:
1000x = 164700
Dividing both sides by 1000 yields:
x = 164700/1000 = $164.70
$22,500 worth of insurance would cost $164.70.
