when you roll two number cubes, what are the odds, in simplest form, in favor of getting two number less than 4 ?

Answers

The odds of getting less than 4 on one cube is 3/6 so 1/2 and if you roll two cubes the odds are 1/2 times 1/2 so the odds of getting two numbers less than 4 is 9/36 or in simplest form, 1/4

First, it depends on the answer. If you are on the same quiz, the options should be

A) 1:3

B) 3:1

C) 1:4

D) 4:1

The answer is C or 1:4.

Because it is in it's favor, the "1" would go first, standing as the numbers before "4" on a cube. The probability in fraction form would be 3/6, or simplified to 1/2. P ( >3, > 3) = P ( >3) = 1/2 x 1/2 = 1/4. This leaves 1:4 being you're answer.

At a baseball game, a vender sold a combined total of 170 sodas and hot dogs. the number of hot dogs sold was 50 less than the number of sodas sold. find the number of sodas sold and the number of hot dogs sold

Answers

Let the number of sodas sold be x and the number of hotdogs sold be y. We can assemble a system of equations from the information given and solve.

x+y=170 (We know that soda + dogs is 170)

x-50=y (We know that dogs is equal to 50 less than sodas)

We can use substitution to solve this system of equations.

x+y=170

Sub in the value of y from the second equation

x+(x-50)=170

2x-50=170

2x=220

x=110

We now know the number of sodas sold was 110. Lets now plug this value into the equation to solve for y.

x+y=170

110+y=170

y=60

So, there were 60 hotdogs sold and 110 sodas sold.

1) Round 168,356 to the nearest ten thousand.2) Round 446,221 to the nearest ten3) Round 45,122 to the nearest ten thousand.4) Round 7,782 to the nearest hundred.

Answers

Answer:

1) 170,000

2) 446,220

3) 50,000

4) 7,800

Step-by-step explanation:

When we round a number to the nearest hundred then we check the digit at tens place,

If the digit is less than 5 then the number is rounded to previous thousand and if it is 5 more than 5 it is rounded to the next thousand,

While, in the case of rounding nearest ten and ten thousand we check the digit at ones place and thousand placerespectively.

1)168,356 to the nearest ten thousand is 170,000 ( ∵ thousand place digit = 8 > 5 )

2) 446,221 to the nearest ten is 446,220 ( ∵ ones place digit = 1 < 5 )

3) 45,122 to the nearest ten thousand is 50,000 ( ∵ thousand place digit = 5 ≥ 5 )

4) 7,782 to the nearest hundred is 7,800 ( ∵ tens place digit = 8 > 5 )

1)170,000
2)446,220
3)50,000
4)7,800

Answers

When you roll a cube once, the smallest number it can show is 1, and the biggest one is 6. So when you roll it twice, the smallest possible sum of both results is 2, and the biggest one is 12. . . . . . Just like list 'b' .
