Using no other digits except 2 and 5 write down, if possible, a three-digit multiple of 6

Answers

Answer:

225

Step-by-step explanation:

Some other numbers that would work are:

255, 525, 555

Answer:

252, 522, 222, and 552

Step-by-step explanation:

For a number to be divisible by 6, it needs to be divisible by both 2 and 3. For a number to be divisible by 2, it needs to end in an even number, and the only even number we can use is 2.

So far our number is _ _ 2.

For a number to be divisible by three, its digits have to add up to a multiple of three. As of now we need to fill in the hundreds and tens place, and there are 4 combinations to check: 2, 5; 5, 2; 2, 2; and 5, 5.

Case #1: 2, 5

We are checking to see if the number 252 is divisible by six.

2 + 5 + 2 = 9

Since the numbers add up to a multiple of 3, 252 is divisible by 6.

Case #2: 5, 2

We are checking to see if the number 522 is divisible by six.

5 + 2 + 2 = 9

Since the numbers add up to a multiple of 3, 522 is divisible by 6.

Case #3: 2, 2

We are checking to see if the number 222 is divisible by six.

2 + 2 + 2 = 6

Since the numbers add up to a multiple of 3, 222 is divisible by 6.

Case #4: 5, 5

We are checking to see if the number 552 is divisible by six.

5 + 5 + 2 = 12

Since the numbers add up to a multiple of 3, 552 is divisible by 6.

x + 3y = 19c
a.​

Answers

9514 1404 393

Answer:

  (x, y) = (4, 5)

Step-by-step explanation:

We notice that the coefficients of y are opposites, so we can eliminate y by adding the two equations together.

  (4x -3y) +(x +3y) = (1) +(19)

  5x = 20 . . . . . . simplify

  x = 4 . . . . . . . . .divide by 5

Substituting into the second equation gives ...

  4 +3y = 19

  3y = 15 . . . . . . . subtract 4

  y = 5 . . . . . . . . . divide by 3

The solution is (x, y) = (4, 5).

What is the solution for the equation 2x+8=28?
Answers above

Answers

Answer:

x = 10

Step-by-step explanation:

Answer:

6.666666667

Step-by-step explanation:

3x+8=28

Subtract 8 from both sides.

3x=28−8

Subtract 8 from 28 to get 20.

3x=20

Divide both sides by 3.

[tex]x=\frac{20}{3}[/tex]

Events A and B are mutually exclusive. Find the missing probability.
P(B) = 7/20 P(A or B) = 7/10 P(A) = ?
A) 3/5 B) 7/20 C)4/5 D) 1/5

Answers

Answer:

B, 7/20

Step-by-step explanation:

If two events are mutually exclusive that means that there is no intersection

so in the union formula: AUB=A+B-A∩B

A∩B=0

we can write P(a)=x

7/10=7/20+x+0

7/10-7/20=x

x=7/20

In this scenario, we've to collect like terms in order to.wolve for x. This will be:

9 - x < - 11

- x < - 11 - 9

- x < - 20

Divide both side by -1

Let the random variable X be the number of rooms in a randomly chosen owner-occupied housing unit in a certain city. Here are the distributions of the number of rooms for owner-occupied units and renter-occupied units:

Rooms 1 2 3 4 5
Owned 0.003 0.002 0.023 0.105 0.218
Rented 0.008 0.027 0.287 0.362 0.165

Owned 0.225 0.198 0.149 0.053 0.024

Required:
a. Express "the unit has 7 or more rooms" in terms of X. x≥7. What is the probability of this event?
b. Express the event {X > 7} in words.
c. What important fact about discrete random variables does comparing your answers to (a) and (b) illustrate?


Answers

Answer:

Part a:

"The unit has 7 or more rooms" in terms of X is given by the unit which has 7, 8, 9 or 10 rooms.

P{ X≥7}= 0.424

Part b:

The event {X > 7} in words is that the unit has more  than 7 rooms. .

Part C:

A continuous random variable  is given by intervals of numbers

A discrete random variable is the variable that is obtained by counting.

Step-by-step explanation:

Part a:

"The unit has 7 or more rooms" in terms of X is given by

{ X≥7} = {x=7} + {x=8} + {x=9} + {x=10}

the unit which has 7, 8, 9 or 10 rooms.

The probability of this event is given by

P{ X≥7} =P {x=7} + P {x=8} + P {x=9} + P {x=10}

P{ X≥7} = 0.198 + 0.149+ 0.053 + 0.024

P{ X≥7}= 0.424

Part b:

The event {X > 7} in words is that the unit has more  than 7 rooms. This does not include the unit having 7 rooms.

Part C:

A continuous random variable takes all the values in the given interval as in part a.The random variable X takes the values between 7 and 10 inclusive of 7.

A discrete random variable is the variable that is obtained by counting as in part b. The variable X takes the values of the units with 8 , 9 or 10 rooms.
