2. A study done by Omega Airlines showed that 44% of all travel on this airline is done for business purposes. Northeast Airlines conducts the same study and concludes that 55% of their passengers
are business travelers. If the two studies are random with 450 and 380 people surveyed
respectively, is there significant evidence to say that the proportion of people traveling by air for
business purposes is different for the two airlines? Carry out a complete hypothesis test to answer
this question

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
