$\bold{\dfrac{3}{52}}=5.8\%$

Step-by-step explanation:

$\dfrac{\text{\# of "8 of hearts"}}{\text{total number of cards}}\ or\ \dfrac{\text{\# of "9 of hearts"}}{\text{total number of cards}}\ or\ \dfrac{\text{\# of "10 of hearts"}}{\text{total number of cards}}\\\\\\\rightarrow \quad \dfrac{1}{52}+\dfrac{1}{52}+\dfrac{1}{52}\quad =\quad \large\boxed{\dfrac{3}{52}}$

Mathematics

D. K'(-4, 8)

Step-by-step explanation:

Given the coordinate (x,y), if this coordinate is dilated by a factor of k, the resulting coordinate will be expressed as (kx, ky). Note that each coordinate is multiplied by the scale factor.

Similarly considering the coordinate K(-1, 2) according to the question. If this coordinate is dilated by a factor of 4, the resulting coordinate is expressed as;

= K'(4(-1), 4(2))

= K' (-4, 8)

Hence the coordinate of K' will be at (-4, 8)
