The sale was 55$ because if you subtract those you get 55 which is the difference between the two
They should still be 280 miles apart on the map i belive.
Answer:
A. In a binomial distribution, the value ofx represents the number of successes in n trials, while in a geometric distribution, the value ofx represents the first trial that results in a success.
Step-by-step explanation:
Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
The probability mass function for the Binomial distribution is given as:
The geometric distribution represents "the number of failures before you get a success in a series of Bernoulli trials. This discrete probability distribution is represented by the probability density function:"
The most important difference is that in the binomial distribution, the value of x represents the successes in n trials.
And by the other hand in the geometric distribution, x represents the number of failures before you get a success in a series of Bernoulli trials.
So then the best answer for this case is:
A. In a binomial distribution, the value of x represents the number of successes in n trials, while in a geometric distribution, the value ofx represents the first trial that results in a success.
I find the following method easiest to factor this equation.
1. First, fill in what you know would be the factors for the first value, 3x^2. The number 3 only has 2 factors: 3 and 1. Therefore, we know the first values are:
(3x _____)(x_____)
2. Next, figure out what the possible factors for the last value would be (-6). The following combinations are possible:
2 and -3 OR -3 and 2
-2 and 3 OR 3 and -2
-1 and 6 OR 6 and -1
1 and -6 OR -6 and 1
3. Plug in the combinations into step 1 and see which gives you the correct answer:
<span>(3x + 2)(x - 3) = 3x^2 - 7x - 6 --> no
</span>(3x - 3)(x + 2<span>) = 3x^2 + 3x - 6 --> no
</span>(3x - 2)(x + 3) = 3x^2 + <span>7x - 6 --> YES</span>
Answer: x-int: (-1/2,0)
y-int: (0,-1/4)
Step-by-step explanation:
x-5y+3=3x-y+4
x-int: x-5(0)+3=3x-0+4
x+3=3x+4
-2x=1
x=-1/2 ==>(-1/2,0)
y-int: 0-5y+3=3(0)-y+4
-5y+3=-y+4
-1=4y
y=-1/4 ==>(0,-1/4)
