Answer:

0.8

Step-by-step explanation:

Find the mean of the list:

(0.2, 0.21, 0.17, 3.22, 0.2)

The mean of a list of numbers is given by:

(sum of elements)/(number of elements)

(sum of elements) = 0.2 + 0.21 + 0.17 + 3.22 + 0.2:

(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/(number of elements)

Counting, we see that the list has 5 elements:

(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/5

0.2 + 0.21 + 0.17 + 3.22 + 0.2 = 4:

4/5

4/5 = 0.8:

Answer:  0.8

Answer:

0.8

Step-by-step explanation:

The mean of the data set can be found by adding all terms together and dividing by the amount of terms there is. In this case, add all the numbers and divide by 5:

(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/5 =

(4)/5 = 0.8

0.8 is the mean for the given set.

Are the two parabolas defined below similar or congruent or both? Justify your reasoning. Parabola 1: The parabola with a focus
Dominik [7]

Answer:

They are similar by a factor of 14

Step-by-step explanation:

From the general equation of a parabola opening up (since the directrix is on the y axis and the focus is upwards this line) the focus coordinates are:

Focus = (h,k+p) = (0,2)

So h=0 and k+p=2, for the directrix:

y = k-p=-4

solving k and p from the two equations above:

k=-1 and p=3

So for Parabola 1 the equation would be:

x^{2} =4*3(y+1)

For Parabola 2 the general equation is:

x^{2} =4*(3/2)(y)

here h=0, k=0, p=3/2 so focus is (0,3/2), directix is y=-3/2, they have the same orientation.

they are not congruent. For them to be similar it must comply:

x_{1}=k x_{2}\\y_{1}=ky_{2} => (1/12)x_{1} ^{2} -1 = k(1/6)x_{2} ^{2}

replacing x_{1} and solving for k:

(1/12)(kx_{2}) ^{2} -1 = k(1/6)x_{2} ^{2}\\ (1/12)k^{2} x_{2}^{2}-1 = k(1/6)x_{2} ^{2}\\k-12 = (12/6)=2\\k = 2+12=14\\

They are similar by a factor of 14
