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

Where does the graph of y=-3x-18 intersect with the x axi

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)

Angle K in △MKL is a right angle.

wel

Hypotenuse= ML
Perpendicular=KL=15
Base= KM=8

By using Pythagoras theorem.

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

Therefore ML= 17...
