Answer:

The probability of rolling a 3 and then a 5 is 1/36.

Step-by-step explanation:

Rolling a six sided die is an independent event.  That means for each roll, you have the same chance of rolling a number as the previous roll.  Since there are six different numbers on a die, then there are six different outcomes for each roll - 1, 2, 3, 4, 5 or 6.  The chances that you would roll a '3' is 1 out of 6, or 1/6.  The chances that you would roll a '5' is also 1 out of 6, or 1/5.  However, when we combine these events, we need to take each probability and multiply them.  So, the probability of rolling a '3' and then a '5' is 1/6 x 1/6 or 1/36.

Order from least to greatest.<br> 1/2, 1/8, 1/16, -0.6
babunello [35]

Answer:

->   -0.6, 1/16, 1/8, 1/2

Step-by-step explanation:

Since 0.6 is negative, that would be the most smallest value. All of the fractions have a numerator of one, so the bigger the denominator, the smaller the value of the fraction is.

Solve for X
sweet-ann [11.9K]

Answer:

x = 1035 = MXXXV

Step-by-step explanation:

<u>Roman Numbers </u>

It's an ancient number system developed in Rome where numbers are represented by the letters {I,V,X,L,C,D,M}. The value of each are, respectively {1,5,10,50,100,500,1000}. If some letter is repeated, then it's value must be multiplied by the number of times the letter is present. For example, XXVII has two X's and two I's, so the conversion is 10+10+5+1+1=27.

If a less-valued letter appears before a greater one, it subtracts. For example CDI=-100+500+1=401

Our numbers are

MMMMMMMMCDXV=8*1000-100+500+10+5=8415

MDCCCLXIII = 1000+500+300+50+10+3=1863

DLXI = 500+50+10+1=561

XXVII = 20+5+2=27

We now operate in our numerical system

\displaystyle x = \frac{MMMMMMMMCDXV * MDCCCLXIII}{DLXI * XXVII}

\displaystyle x = \frac{8415 * 1863}{561 * 27}

\displaystyle x = \frac{15677145}{15147}

\displaystyle x = 1035

Converting back to roman

\boxed{\displaystyle x = MXXXV}

Find the area of the shaded region!<br>please solve this with solutions !ASAP​
bija089 [108]

the area of the shaded part is 30. 89 cm²

<h3>How to determine the area</h3>

We have the shape to be a rectangle

The area of the shaded part should be;

Area of rectangle - 2 ( area of a semi circle)

The formula for area of a rectangle

Area = length × width

Area = 12 × 12

Area = 144 cm²

Area of a semicircle = 1/2 πr²

Area = 1/ 2 × 3. 142 × 6²

Area = 56. 56 cm²

Area of shaded part = area of rectangle - 2( area of semicircle)

Area of shaded part = 144 - 2(56. 56)

Area of shaded part = 144 - 113. 11

Area of shaded part = 30. 89 cm²

Thus, the area of the shaded part is 30. 89 cm²
