Answer:
5) 13% 7) 3/28
Step-by-step explanation:
<u>5)</u>
total number of marbles: 2 + 3 + 5 + 1 + 2 + 2 = 15 marbles.
probability its blue: __in fraction
in percentage: * 100 = 13%
<u>7)</u>
total number of marbles: 4 + 5 + 2 + 9 + 1 = 21
probability of selecting a red marble: 5/21
then 1 marbles is reduced as not replaced.
total marbles: 21 - 1 = 20
probability of getting orange marble: 9/20
total probability: 9/20 * 5/21 = 3/28

A dilation is a transformation, with center O and a scale factor of k
that is not zero, that maps O to itself and any other point P to P'.
The center O is a fixed point, P' is the image of P, points O, P and P'
are on the same line.
Thus, a dilation with centre O and a scale factor of
maps the original figure to the image in such a way that the
distances from O to the vertices of the image are times the distances
from O to the original figure. Also the size of the image are <span> times the
size of the original figure. Also the two resulting figures (i.e. the image and the pre-image are congruent)
Thus in the dilation of triangle DEF, the following are true.</span>
<span>∠F corresponds to ∠F'.
The measure of ∠E' is the measure of ∠E.
△DEF ≈ △D'E'F'</span>
