Answer:

(1, 2) is a solution to this system of equations

Step-by-step explanation:

Plug in (1, 2) into each equation

17x + y = 19

17(1) + 2 = 19

17 + 2 = 19

19 = 19 ----------->YES

8x + 5y = 18

8(1) + 5(2) = 18

8 + 10 = 18

18 = 18 ------------------->YES

Answer:

(1, 2) is a solution to this system of equations

Answer:

P=0.61 or 61%

Step-by-step explanation:

If we pick a random point within the circle, it can fall in the white area or in the pink area. Since the sum of both areas makes the sample space or the total area of the circle, we can compute the probabilities according to the ratio of the areas with respect to the total area, that is:

$\text {Probability of falling in the white area} = \frac{\text{White area}}{\text{Circle area}}$

The area of the circle is

$A_c=\pi r^2$

The area of both the triangles is

$A_t=2*\frac{bh}{2}$

Where r=4 cm, b=3 cm, h= (4+2.5) cm = 6.5 cm

Then we have:

$A_c=\pi 4^2=16\pi \ cm^2=50.27\ cm^2$

$A_t=19.5\ cm^2$

The white area is obtained by subtracting both areas

$A_w=A_c-A_t=50.27-19.5=30.77\ cm^2$

So the probability is

$P=\frac{30.77}{50.27}=0.61$

You have a bag that contains 20 quarters, 20 dimes, and 15 nickels. When randomly selecting two coins with no replacement find t

iogann1982 [59]

Answer:

P(2 quarters) = 19/ (13*16) = 19/208 = 0.0913

Step-by-step explanation:

probability of getting 2 quarters?

ok

first draw: there are 20 quarters to choose from

second draw: there are 19 quarters left to choose

so Total coins are 65 coins

P(2 quarters) = P( 1st quarter)* P(2nd quarter)

P(2 quarters) = 20/65 * (19/64)

P(2 quarters) = 4/13 * 19/64

P(2 quarters) = 19/ (13*16) = 19/208
