Answer:

x=20

Step-by-step explanation:

You make an equation knowing that the angles add up to 180.

80+5x=180---> 5x=100----> x=20

Please write a comment if I am wrong.

Hope this helped you!

Answer:

x = 20 degrees

Step-by-step explanation:

All three angles added together form a straight line. A straight line is 180 degrees

3x+ 80 + 2x = 180

Combine like terms

5x+80 = 180

Subtract 80 from each side

5x+80-80 = 180-80

5x= 100

Divide each side by 5

5x/5 = 100/5

x = 20

Consider a game in which a participant pays $2 to roll a die. The participant receives $3 if they roll a 1 (i.E. They go up by a

Sauron [17]

Answer:

The expected monetary value of a single roll is $1.17.

Step-by-step explanation:

The sample space of rolling a die is:

S = {1, 2, 3, 4, 5 and 6}

The probability of rolling any of the six numbers is same, i.e.

P (1) = P (2) = P (3) = P (4) = P (5) = P (6) = $\frac{1}{6}$

The expected pay for rolling the numbers are as follows:

E (X = 1) = $3

E (X = 2) = $0

E (X = 3) = $0

E (X = 4) = $0

E (X = 5) = $0

E (X = 6) = $4

The expected value of an experiment is:

$E(X)=\sum x\cdot P(X=x)$

Compute the expected monetary value of a single roll as follows:

$E(X)=\sum x\cdot P(X=x)\\=[E(X=1)\times \frac{1}{6}]+[E(X=2)\times \frac{1}{6}]+[E(X=3)\times \frac{1}{6}]\\+[E(X=4)\times \frac{1}{6}]+[E(X=5)\times \frac{1}{6}]+[E(X=6)\times \frac{1}{6}]\\=[3\times \frac{1}{6}]+[0\times \frac{1}{6}]+[0\times \frac{1}{6}]\\+[0\times \frac{1}{6}]+[0\times \frac{1}{6}]+[4\times \frac{1}{6}]\\=1.17$

Thus, the expected monetary value of a single roll is $1.17.

Least to greatest<br> 3/4,5/8,3/7,1/3,2/5

tangare [24]

Answer:

1/3 < 2/5 < 3/7 < 5/8 < 3/4

Step-by-step explanation:

Using the given inputs:

3/4 5/8 3/7 1/3 2/5

The least common denominator (LCD) is: 840.

Rewriting as equivalent fractions with the LCD:

3/4= 630/840

5/8= 525/840

3/7= 360/840

1/3= 280/840

2/5= 336/840

Sorting this by the numerators of the equivalent fractions in order from least to greatest:

1/3= 280/840= < 2/5= 336/840= < 3/7= 360/840= < 5/8= 525/840= < 3/4 = 630/840

Therefore, the sorted inputs in order from least to greatest is:

1/3 < 2/5 < 3/7 < 5/8 < 3/4

Hopes this helps!

Have a good evening! :)

(x = 3)<br> y=x+5 <br> How would I solve this problem

Flura [38]

So it would be y=3+5 so you really just add 3+5 and that’s 8 so it would be y=8

8th math , plwase help

astra-53 [7]

Interior angles of triangles equal 180.

So angleTUV = 24 degrees

A straight line will equal 180 degrees. If angle U is 24 degrees in the interior angle, the exterior is 156 degrees.

Angle VUX is 156 degrees
