Ann [662]3 years ago
6 0

Answer:

\boxed{ \text{953 seats}}\\

Step-by-step explanation:

Five of Peak Cinema's theatres are medium-sized (98 seats) and five are small (half of 98 = 49 seats).

Their total number of seats is

5 × 98 + 5 × 49 = 490 + 245 = 735 seats

Add the separate iMax theatre and the total capacity of the complex becomes

735 + 218 = 953 seats

\boxed{ \textbf{The entire movie theatre complex has 953 seats.}}\\

g Bonus: Assume that among the general pediatric population, 7 children out of every 1000 have DIPG (Diffuse Intrinsic Pontine G
patriot [66]

Answer:

0.9586

Step-by-step explanation:

From the information given:

7 children out of every 1000 children suffer from DIPG

A screening test designed contains 98% sensitivity & 84% specificity.

Now, from above:

The probability that the children have DIPG is:

\mathbf{P(positive) = P(positive \  |  \ DIPG) \times P(DIPG) + P(positive  \ | \  not \DIPG)\times P(not  \ DIPG)}= 0.98\imes( \dfrac{7}{1000}) + (1-0.84) \times (1 - \dfrac{7}{1000})

= (0.98 × 0.007) + 0.16( 1 - 0.007)

= 0.16574

So, the probability of not having DIPG now is:

P(not \ DIPG \  |  \ positive) = \dfrac{ P(positive  \ | \  not DIPG)\timesP(not \  DIPG)} { P(positive)}

=\dfrac{ (1-0.84)\times (1 - \dfrac{7}{1000}) }{ 0.16574}

=\dfrac{ 0.16 ( 1 - 0.007) }{0.16574}

= 0.9586

fiasKO [112]
Intersect with x axis indicates that x value would be Zero

Thus when x = 0 

y would be 
y = -18

Therefor intersection would be at (0,-18)

  1. Hypotenuse= ML
  2. Perpendicular=KL=15
  3. Base= KM=8

By using Pythagoras theorem.

  • h²=p²+b²
  • ML²=15²+8²
  • ML²=225+64
  • ML=√289

Therefore ML= 17...
