If you rolled two dice what is the probability that you would roll a 4 or a 5

Masja [62]2 years ago

Hello there! Given that normal dice are numbered 1-6, individually rolling a 4 or a 5 would give a 1/6 probability. That converts to about 17% as a percentage because we can multiply 1 by 100 to get 100/6, then divide 100 by 6 to get 16.6666. When rounding, that gives approximately 17%. However, if we combined probabilities, we would find that rolling a 4 or a 5 collectively gives a 2/6 probability, which is approximately 33% as a decimal.

In terms of individual probabilities, you would be 17% likely to roll one of them. In terms of collectiveness, the likelihood of rolling a 4 or 5 would render 33% on each die. If you need additional help, let me know and I will gladly assist you.

use a system of linear equations with two variables and two equations to solve. a number is 11 more than another number. twice t
Eva8 [605]

The value of required two numbers x and y are 7 and -4 respectively. These values are find out using Elimination method.

Let the required first number and second numbers be x and y respectively .

We have given that, one Number is more than other by 11

i.e., the difference of two numbers is equal to 11

x - y = 11. …..(1)

And twice the sum of the two numbers is 6 i.e.,

2(x + y) = 6 => 2x + 2y = 6 => x +y = 3 …….(2)

Now , equation (1) and (2) are linear equation with two variables x and y .

We shall solve above two equations and find out the value of two variables. Using Elimination method , In which value of one variable is find out by eliminate the second variable through their coefficient comparison.

Added the equation ( 1) and (2) we get, 2x = 14 => x = 7

Put the value of x in equation (1) we get,

7 – y = 11 => y = -4

Thus, we get the values of two variables x and y is 7 and -4 respectively.

The smoke alarms in an office building need new batteries. Larry has 1,311 batteries.Each office in the building needs 6 batteri
Likurg_2 [28]

Answer:

218 ; 3

Step-by-step explanation:

Given that:

Total number of batteries Larry has = 1,311

Batteries needed per office = 6

Number of offices that will get new batteries :

Total batteries / batteries needed per office

= 1311 / 6

= 218.5

Take the whole and ignore the decimal :

Hence, 218 offices will get new batteries

Number of batteries that will be left :

Total batteries - (218 * 6)

1311 - 1308 = 3

At the store, Jason find the volume of a soda pack is 423.9 in.³. If each cylinder shaped can has a height of 6 inches and a dia
Marina86 [1]

Answer : The correct option is, (A) 10

Step-by-step explanation :

First we have to calculate the volume of cylinder shaped can.

Formula used:

Volume of cylinder = π r² h

where,

r = radius of cylinder

h = height of cylinder

Given:

Diameter of cylinder = 3 in

Height of cylinder = 6 in

Radius of cylinder = \frac{Diameter}{2}=\frac{3in}{2}=1.5in

Now putting all the given values in the above formula.

Volume of cylinder = π r² h

Volume of cylinder = 3.14 × (1.5 in)² × 6 in

Volume of cylinder = 42.39 in³

Now we have to determine the number of soda cans are in a pack.

Number of soda cans are in a pack = \frac{\text{Volume of soda pack}}{\text{Volume of cylinder shaped can}}

Number of soda cans are in a pack = \frac{423.9in^3}{42.39in^3}

Number of soda cans are in a pack = 10

Therefore, the number of soda cans in a pack are 10.

Write the fraction 7/1000 as a percent to the nearest hundredth of a percent.
Hunter-Best [27]

You're answer is: 0.7%

Explanation:

To get the answer, simply multiply 100 by 7/1000 which would give you 0.007. Then once you get 0.007 you'll need to multiply again by 100. Which would give you 0.7%

7/1000×100=0.007

0.007×100=0.7%

That being said, 0.7% is the correct answer.
