We are given arc KL is 12x+4, arc KJ is 8x-6, and angle E is 99 degrees. What is the actual degree measure of arc KJ? *
Svetlanka [38]

The  actual degree measure of arc KJ is 99 degrees

<h3>Circle geometry</h3>

From the given informtion

arc KL = 12x+4

arc KJ = 8x-6

<E = 99 degrees

The equation required to get the value of "x" is given as:

12x + 4 + 8x - 6 + 99 = 360

20x + 97 = 360

20x = 360 - 97

20x = 263

x = 13.15

For the arcKL

arcKJ = 8(13.15) -  6

arcKJ = 99degrees

HEnce the  actual degree measure of arc KJ is 99 degrees

TV studio has brought in 9 boy kittens and 6 girl kittens for a cat food commercial. The director is going to choose 9 of these
Amanda [17]

Answer:

probability = 0.2517

Step-by-step explanation:

given data

boy kittens = 9

girl kittens = 6

choose kittens at random = 9

solution

total kitten are = 9 + 6 = 15

first we get here total no of probability that is

n(s) = 15 C 9

n(s) = \frac{15!}{9!(15-9)!}  

n(s) =5005

and

total way to chose 5 boy kittens is = 9 C 3

n(3) = \frac{9!}{3!(9-3)!}  

n(3) =  84

and

total way to chose 4 girl kittens is = 6 C 4

n(4) = \frac{6!}{4!(6-4)!}  

n(4) = 15

so

total way to chose 5 boy kittens and 4 girl kittens is

total way = 84 ×15  = 1260

so probability that the director chooses 5 boy kittens and 4 girl kittens is

probability = \frac{1260}{5005}  

probability = 0.2517
