The film lasted until 8:27.

This is true because 102 minutes is 1 hour and 42 minutes. If you add 1 hour and 42 minutes onto 6 hours and 45 minutes, the beginning time then. You would get 8 hours and 27 minutes.

This is my equation. ---->
6:45
+1:42
_____
7:87 <---- But that isn't correct because 87 minutes is over an hour.

So if you do the correct numbers you would get 8:27 as your answer!

HOPE I HELPED!!! :D

This is the first step in which construction?

slavikrds [6]

Answer:

Option A is correct.

Step-by-step explanation:

The first step in the construction of a square inscribed in a circle is to draw a diameter of the circle.

Then we have to draw perpendicular bisector of the diameter using a compass.

Therefore, the perpendicular bisector will be another diameter of the circle and both the diameters will meet at the center of the circle.

Now, join the points with straight lines in order where the two diameters meet the circle. And finally, we will get a square inscribed in the circle.

Hence, option A is correct. (Answer)

Please explain to me how to find y. I’m so confused.

Every triangle angles add up to 180.

So because one angle is 90 degrees you would subtract it from 180 to get 90 and then divide it by two which is 45 degrees.

Hope this helps, have a nice day! :)

today's local newspaper lists 20 stocks of local interest. of those stocks ten increased five decreased and five remained unchan

coldgirl [10]

Answer:

P(x=2) = 0.2368

Step-by-step explanation:

given data

stocks of local interest N = 20

stocks increased K = 10

stocks decreased = 5

remained unchanged = 5

solution

we take here no of stock that are increased randomly n = 2

so here Hypergeometric random variable can take integer value

{max(0, n+k - N ), min(n,K) } = {0,2}

so here

P(x=2)

P(x=k) = $\frac{(^K_k)\times (^{N-K}_{n-k}) }{(^N_n)}$ .......................1

P(x=2 ) = $\frac{(^{10}_2)\times (^{20-10}_{2-2}) }{(^{20}_2)}$

solve it we get

P(x=2 ) = 0.236842

now we use excel function as

HYPGEOM.DIST (k,n,N.cumulative) .....................2

so it will be

HYPGEOM.DIST (2,2,10,,false)

we get

HYPGEOM.DIST (2,2,10,,false) = 0.236842

P(x=2) = 0.2368
