Find the probability of exactly three successes in six trials of a binomial experiment in which the the probability of is 50%.
posledela

Answer: 31.25%

Two ways to solve this problem:

#1: Use the formula: P(X=x)={n}Cx_{} *p^{x}*(1-p)^{n-x}

#2 Use a graphing calculator and use the function binompdf(n, p, x)

  • x = 3
  • n = 6
  • p = 0.5

#1: Formula:

P(X=3)=_{6}C_{3}*0.5^{3} *(1-0.5)^{6-3}=\frac{6!}{3!(6-3)!} *0.5^{3} *0.5^{3}\\=\frac{6!}{3!*3!} *0.5^{3} *0.5^{3}=20*0.125*0.125=0.3125

#2: Faster method

binompdf(6, 0.5, 3) = 0.3125

  • [Right Triangles Only] Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

<u>Step 1: Define</u>

We are given a right triangle. We can use PT to solve for the missing length.

<u>Step 2: Identify Variables</u>

Leg <em>a</em> = 6

Leg <em>b</em> = <em>x</em>

Hypotenuse <em>c</em> = √89

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Set up equation:                    6² + x² = (√89)²
  2. Isolate <em>x</em> term:                        x² = (√89)² - 6²
  3. Exponents:                             x² = 89 - 36
  4. Subtract:                                 x² = 53
  5. Isolate <em>x</em>:                                 x = √53

Question 5 is attached! 11 pts +6 for the best!

6 - 8c = -10 - 10c

and you're solving for c. what you really need to do in problems like this is combine like terms: -10 and 6 are like terms, because they are numbers without variables. -8c and -10c are like terms, because they are variables with coefficients.

6 - 8c = -10 - 10c  ... add 10c to both sides
6 + 2c = -10 ... subtract 6 from both sides
2c = -16 ... divide both sides by 2
c = -8 is your result.
