In a bag of 100 marbles comprised of many colors, 25 are blue. suppose marbles are selected at random.

satela [25.4K]

Solution: The number of ways we can arrange 3 blue marbles if a set of 5 marbles is selected is:

$\binom{5}{3}=\frac{5!}{(5-3)!3!}$

$=\frac{120}{2 \times 6}$

$=\frac{120}{12}=10$

Therefore, there are 10 ways we could arrange 3 blue marbles.

Quadrilateral ABCD is inscribed in this circle.

Lelechka [254]

Answer:

m∠C = 122°

Step-by-step explanation:

Opposite angles of a quadrilateral inscribed in a circle are supplementary. This means

m∠A + m∠C = 180°

m∠B + m∠D = 180°

To find angle C we need to find x, then subtract m∠A from 180°

x+20=3x

20=2x

x=10

Now we substitute 10 in for x

m∠A=2(10)+38

m∠A=20+38

m∠A=58°

Now we subtract this value from 180.

m∠C=180-58

m∠C=122°

Step-by-step explanation:

we have

$\frac{1}{z}=\frac{(4/5)}{8}$

solve for z

$z(\frac{4}{5})=8$

$z=8*5/4$

$z=10$
