Answer:

LR is 12

Step-by-step explanation:

LP is hypotenuse and PR is base so LR is perpendicular

formula to calculate perpendicular is

p^2=H^2 -b^2

p^2=15^2-9^2

p^2=225-81

p^2=144

p=12(root of 144 is 12)

dem82 [27]

<h2>Answer:</h2><h2>The probability of selecting a defective roll followed by another defective roll = $\frac{1}{35}$ </h2>

Step-by-step explanation:

The total number of rolls in a box = 15

The number of defective items = 3

Two rolls are to be selected, one after the other. The probability of selecting a defective roll followed by another defective roll = ?

The probability that the first roll is detective = $\frac{3}{15}$

The probability that the second roll is detective = $\frac{2}{14}$

Required probability = $(\frac{3}{15} ) (\frac{2}{14} )$

= $\frac{1}{35}$
