Answer:

assumption:

drinks are selected with replacement from refreshment stand

note:

i think "choosing" is poorly worded in the problem

use complement of everyone selecting a unique drink:

1-(8*7*6*5)/8^4 = 151/256 = 0.5898

answer -> D 0.59

About 9% of the population has a particular genetic mutation. 400 people are randomly selected. Find the mean for the number of
never [62]

Answer:

36 people

Step-by-step explanation:

The expected value E(X) = mean of sample = np

Where, p = population proportion, p = 9% = 0.09

n = sample size, = 400

The mean of the number of people with genetic mutation, E(X) = np = (400 * 0.09) = 36

Find all of the polar coordinates of point P if P = (7,pi/3)
oee [108]

If P has Cartesian coordinates (7, pi/3), then its Polar coordinates are (square root of ((7)^2 + (pi/3)^2) , arcton (pi/21))

<u>Explanation</u>:

The given coordinates  ( 7 ,  π /3 )  look as if they are already in polar form (radius  =  7 , and angle  =  π/3).

but in case  ( 7 ,  π /3 )  really are Cartesian coordinates (i.e.  ( x , y ) = ( 7 ,  π/3 ) )

The radius is given by  √( x /2  +  y/ 2)  and  the angle by the  arctan  ( y ,x ).

Answer:

L.C.M OF

1) 1/2+1/3+1/5 IS THE L.C.M OF THEIR DINOMINATORS=30

THEREFORE,(15+10+6)/30=31/30

2)1/3 ÷1/2+1/4

=1/3×2/1 +1/4 (D.M.A.S)

=2/3+1/4

=L.CM OF DINOMENATORS 12 AS L.C.M OF 3 AND 4.

(8+3)/12

=11/12
