Find the slope
IceJOKER [234]

Finding the slope from two points is as simple as:

\frac{y2-y1}{x2-x1}

Plug in your quantities:

\frac{-1-3}{6-6}

because, y2 = -1, y1 = 3, x2 = 6, x1 = 6


Solve:

\frac{-4}{0}

This is as far as this equation goes because you cannot divide by zero - are you sure you've provided the correct equation?

According to the "January theory," if the stock market is up for the month of January, it will be up for the year. If it is down
TiliK225 [7]

Answer:

The probability this could occur by chance is approximately 0.003053.

Step-by-step explanation:

This problem can be solved with a binomial distribution, if we imagine that by the end of January the stock market will follow the same pattern for the rest of the year we can define the following random variable:

X = "The stock market will be up for the rest of the year",

and X = 1 if by the end of January the stock market is up and X = 0 otherwise, this way X \sim Bin(1,p) \text{ or } X \sim Bernoulli(p), where p is the probability of success. Next we can define the following random variable:

Y = "Sum of all years where the stock market was up"

Now, the sum of a Bernoulli random variables is a Binomial random variable, in other words Y \sim Bin(n,p), where n is the number of trials and p is the probability of success. The pdf of Y is given by:

P(X = k) = \big {n \choose k}p^k(1-p)^{n-k}, \text{ } k \leq n

The question give us the n = 34, k = 25 and p = 0.5. Now we just have to solve it:

P(X = 25) = \big {34 \choose 25}(0.5)^{25}(1-0.5)^{34-25} = {34 \choose 25}(0.5)^{34} = \\P(X = 25)= 52451256\cdot(0.5)^{34} \approx 0.003053

Which is highly unlikely to happen.

There are 609 skiers in line for the lift if each chair seats 6 people how many skiers will be on the last chair
Zolol [24]

Answer:

3 skiers will be on the last chair

Step-by-step explanation:

Divide 609 skiers by 6 people per chair:

609 ÷ 6 = 101.5 (also can write as 101 and remainder of 3)

Multiply 101 • 6 = 606

609 - 606 = 3
