alexdok [17]

Answer:

P(120< x < 210) =  0.8664

Step-by-step explanation:

given data

time length = 20 year

average mean time μ = 165 min

standard deviation σ = 30 min

randomly selected game between = 120 and 210 minute

solution

so here probability between 120 and 210 will be

P(120< x < 210) = P(\frac{120-165}{30}< \frac{x-\mu }{\sigma }

P(120< x < 210) = P(\frac{-45}{30}< \frac{x-\mu }{\sigma }

P(120< x < 210) = P(-1.5< Z < 1.5)

P(120< x < 210) = P(Z< 1.5) - P(Z< -1.5)

now we will use here this function in excel function

=NORMSDIST(z)

=NORMSDIST(-1.5)

P(120< x < 210) = 0.9332 - 0.0668

P(120< x < 210) =  0.8664

3. Theresa has 20 coins that are dimes and quarters. Together
KiRa [710]

Answer:

  • 15 dimes
  • 5 quarters

Step-by-step explanation:

Let q represent the number of quarters Theresa has. Then the value of her coins is ...

  0.25q + 0.10(20 -q) = 2.75

  0.15q = 0.75 . . . . . . . . . subtract 2.00, collect terms

  q = 0.75/0.15 = 5

Theresa has 5 quarters and 15 dimes.
