A number cube is rolled. Find each probability

Mathematics

1 answer:

never [62]2 years ago

4 0

Step-by-step explanation:

I assume the number cube is a regular one with 6 sides and numbers 1..6.

P(odd) is the probability to get an odd number (1, 3, 5) or if the possible 6 numbers (1..6).

so that is

3/6 = 1/2 = 0.5

P(even) : (2, 4, 6) out of 1..6 is

3/6 = 1/2 = 0.5

P(prime) : (2, 3, 5) out of 1..6 is

3/6 = 1/2 = 0.5

remember, 1 is not a prime number (just a special case), and 2 is a prime number, because it is only divisible by 1 and itself.

10.

P(greater than 6) : that is impossible to get on a die with numbers 1..6.

so, the probability is

0/6 = 0

Find two consecutive integers whose sum is eleven less than three times the smaller integer.

asambeis [7]

Answer:

If you call the smaller integer "x" and the greater integer "y", then:

x+y=3x-11 The sum of the two is 11 less than 3 times the smaller

y=x+1 Because they are consecutive, the greater must be 1 more than the smaller

Then you can solve for x:

x+(x+1)=3x-11 Substitute x+1 for y

2x+1=3x-11 Combine like terms

2x+12=3x Add 11 to both sides

12=x Subtract 2x from both sides

The smaller integer is 12, thus the greater integer is 1 more or 13.

Check:

12+13=3(12)-11

25=36-11

25=25 Yes, so the integers are 12 and 13

Step-by-step explanation:

thats pretty much it

The function f(x) = 2x2 + 2 represents the rate of a bus traveling in miles per hour. The function g(x) = x + 2 represents the t

AlekseyPX

Answer:

(f • g)(3) = 100, the distance in miles the bus traveled

Step-by-step explanation:

The product of (miles/hour) and (hours) is (miles), so only answers with units of distance are applicable. The numbers are ...

f(3) = 2·3² +2 = 20 . . . . miles per hour

g(3) = 3+2 = 5 . . . . hours

so (f·g)(3) = f(3)·g(3) = 20·5 = 100 . . . . miles

This means only the first answer choice is applicable.

Will and tommie bought a giant candy bar composed of 24 pieces. Will ate 1/4 of the bar and Tommie ate 2/3 of the bar. How many

hichkok12 [17]

Answer:

3/24 or 1/8

Step-by-step explanation:

1. convert 1/4 and 2/3 into fractions with common denominators of 24 (since there are 24 pieces.

2. find the multiples of 4 and 3

4, 8, 12, 16, 20, 24 = 5

3, 6, 9, 12, 15, 18, 21, 24 = 8

3. convert the fractions

1/4 * 5/5 = 5/24

2/3*8/8 = 16/24

4. add the fractions.

5/24 + 16/24 = 21/24

5. subtract 21/24 from 24/24 = 3/24

6. reduce by dividing both terms by 3 = 1/8
