Find the equation of the line passing through the points (1,5) and (3,9)​
Arada [10]

Answer:

  • \boxed{\sf{2}}

Step-by-step explanation:

Use the slope formula.

\underline{\text{SLOPE:}}

\Longrightarrow: \sf{\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{Rise}{Run} }

\sf{y_2=9}\\\\\\\sf{y_1=5}\\\\\\\sf{x_2=3}\\\\\\\sf{x_1=1}

\sf{\dfrac{9-5}{3-1} }

Solve.

\sf{\dfrac{9-5}{3-1}=\dfrac{4}{2}=\boxed{\sf{2}}

  • <u>Therefore, the slope is 2, which is our answer.</u>

I hope this helps. Let me know if you have any questions.

You decided to throw a fair die four times.
Finger [1]

Answer:

If all you care about is whether you roll 2 or not, you get a Binomial distribution with an individual success probability 1/6. The probability of rolling 2 at least two times, is the same as the probability of not rolling 2 at zero or one time.

the answer is, 1 - bin(k=0, n=4, r=1/6) - bin(k=1, n=4, r=1/6). This evaluates to about 13%, just like your result (you just computed all three outcomes satisfying the proposition rather than the two that didn’t).
