Nina asked 30 of her friends what they thought about a new movie.
Sunny_sXe [5.5K]
No, this is not a random group of students. Because Nina asked her friends if they liked the movie. For her to ask a random group of people, she would have to go and ask people that she did not know.

PLEASE HELP ASAP!!! I NEED CORRECT ANSWERS ONLY PLEASE!!!
Oksi-84 [34.3K]

Answer:

Step-by-step explanation:

Right triangle trig.  Super fun!  We are given the vertex angle of 27 degrees.  The side across from that angle is 4, and we are looking for the hypotenuse of the triangle.  That is the trig ratio sin.  sin of an angle is equal to the side opposite over the hypotenuse:

sin(27)=\frac{4}{hyp} and, solving for hyp:

hyp=\frac{4}{sin(27)}.  Do that on your calculator in degree mode to get that the hypotenuse, side BD is 8.8 units.

Let us try A

If we put x = -3 , then y= 27-36+3+1=-5 , thus it us not the polynomial of given points

Now moving onto B

If x = -3, then y =-81-27+36-3-1=76

If x= -1 , then y=-1-1+4-1-1=0

If x =0, then y=-0-0+0-0-1=-1

If x =1, then y= -1+1+4+1-1=4

Thus it is also not the polynomial with given point.

Now onto c

x= -3 , y=81+27-36+3+1=76

x=0, y = 0+0+0+0+1=1

x= -1 , y = 1+1-4+1+1=0

x=1 , y= 1-1-4-1+1=-4

x=2, y=16-8-16-2+1=-9

Hence C is the polynomial of given points
