The solution is not a real number because 129 is not a perfect square.

You’re left with:
-7 plus or minus the square root of 129 over 14.

Hope this helps!

Answer:

55,98,27

Step-by-step explanation:

To solve for the angles we must first find y with this equation

3y+5+2y-7=153

We can simplify this

5y-2=153

153+2=155

155/5=31

y=31

We now know y and can plug it into the angles

<A=2y-7

2(31)-7

62-7

<A=55

<B=3y+5

3(31)+5

93+5

<B=98

Now time for the last angle

Since angle BCA and DCB are next to each other they add up to 180

153+x=180

180-153=27

x=27

<BCA=27

The probability of winning on an arcade game is 0.568. If you play the arcade game 22 times, what is the probability of winning

Serggg [28]

The probability of winning 15 out of the 22 games is $P = 0.099$

<h3>what is the probability of winning more than 15 times?</h3>

We know that the probability of winning on the arcade game is 0.568.

Then the probability of losing is:

P = 1 - 0.568 = 0.432

The probability of winning 15 out of 22 games is given by the equation:

$P = C(22, 15)*(0.568)^{15}*(0.432)^{7}$

Where C(22, 15) is the number of combinations of 15 elements that we can make with a set of 22 elements, given by:

$C(22, 15) = \frac{22!}{(22 - 15)!*15!} = \frac{22!}{7!*15!} = \frac{22*21*20*19*18*17*16}{7*6*5*4*3*2*1} = 170,544$

Then the probability is:

$P = 170,544*(0.568)^{15}*(0.432)^7 = 0.099$

the base of this solid crate has an area of 6 square centimeters the height of the crate is 4 meters what is the volume of the c

Tresset [83]

$Area Of Cuboid = length*width*height$

The length * width is the area of the base, so:

$Area Of Cuboid = base*height = 6 * 4 = 24 meters^3$
