How do you do these questions?
Tanzania [10]

Answer:

μ ≈ 2.33

σ ≈ 1.25

Step-by-step explanation:

Each person has equal probability of ⅓.

\left[\begin{array}{cc}X&P(X)\\1&\frac{1}{3}\\2&\frac{1}{3}\\4&\frac{1}{3}\end{array}\right]

The mean is the expected value:

μ = E(X) = ∑ X P(X)

μ = (1) (⅓) + (2) (⅓) + (4) (⅓)

μ = ⁷/₃

The standard deviation is:

σ² = ∑ (X−μ)² P(X)

σ² = (1 − ⁷/₃)² (⅓) + (2 − ⁷/₃)² (⅓) + (4 − ⁷/₃)² (⅓)

σ² = ¹⁴/₉

σ ≈ 1.25

Mr.rodrigues invests half his money in land, a tenth in stocks and a twentieth in bonds . He puts the remaining 35,000 in his sa
Natali5045456 [20]
Let's say <span>Mr.rodrigues's total amount of money is x. 1/2 of his money is in land, 1/10 of his money is in stocks, and 1/20 of his money is in bonds. The remaining is in his savings. Therefore, 1-1/2-1/20-/10 = fraction of money in savings account = 35/100 = 7/20. If 7/20 of his money =35000, then we can say that (7/20)x=35000, and 35000*20=7x, then getting (35000*20/7)=x, which equals (5000*20)=100,000 dollars.</span>

it cost 270 for 3 people to go on a fishing trip how much does it cost for 10 people to go on the fishing trip
sdas [7]
270 divided by 3 = 90.

90  is the cost per person.

Now you do 90 times 10 to get the total for all 10  people.

90 times 10= 900.
