What is the probability of rolling a number less than five on a standard number cube (6 sides)

Mathematics

fgiga [73]3 years ago

<h3>Answer:  2/3</h3>

Here are the outcomes that are less than five = {1, 2, 3, 4}. There are A = 4 values here.

Here are all the outcomes possible: {1, 2, 3, 4, 5, 6}. There are B = 6 ways to roll a single number cube (aka dice).

Divide the two values: A/B = 4/6 = (2*2)/(2*3) = 2/3

The fraction 2/3 is approximately equal to 0.667 which converts to 66.7%

Find two consecutive odd integers if twice the larger, increased by the smaller equals 37,
Alexxx [7]

Answer:

11 and 13

Step-by-step explanation:

the first (smaller) odd integer can be called x

the second (larger) odd integer can be called x+2

2(x+2)+x = 37

<em>[simplify . . .]</em>

2x+4+x = 37

3x+4 = 37

<em>[subtract 4 from each side]</em>

3x = 33

<em>[divide each side by 3; find smaller odd integer]</em>

x = 11

<em>[add 2 to find larger odd integer]</em>

x+2 = 13

Select the list that correctly includes all of the coefficients from the problem
matrenka [14]

Answer:

( B.) 6, 1, -2 , -4

Step-by-step explanation:

A coefficient is a number multiplied by a variable. So, in this case let's take a look at the problem.

-2+6y+m-2y+8-4m

Now we have to find the numbers that have a variable next to it

which are 6,m,-2, and -4

(If you are wondering that why m is a coefficient its because it is also known as 1m)

Final answer = 6, 1, -2 , -4

Hope this helps!
