PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I don't understand how to do this. :'(
natulia [17]

Answer:

Step-by-step explanation:

First and foremost, all quadratics have a domain of all real numbers (as long as we are not given only a portion of the graph, or one with endpoints. Our graph does not have endpoints, so it is assumed that the tails will continue to go down into negative infinity and at the same time, the x coordinates will keep growing as well.) Since our quadratic is upside down, it has a max. That means that none of the values on the graph will be above that point. All the values will be below that highest point (the highest y-value). Y-values indicate range, and since our highest y-value is at y = 2, then the range is

y ≤ 2

What is the probability you roll doubles on two 6 sides dice <br> please show work
Mars2501 [29]

Answer:

1/6

Step-by-step explanation:

We can start by determining all the different combinations we can get.

We are using 6 sided dices, so we have a chance of getting 6 different numbers for each dice.

If we only have 1 dice, the our possible values would be:

1, 2, 3, 4, 5, 6

However, we have 2 dices. As such, our combinations have been multiplied, and now our possibilities are:

(1 , 1) , (1 , 2) , (1 , 3) , (1 , 4) , (1 , 5) , (1 , 6) , (2 , 1) , (2 , 2) , (2 , 3) , (2 , 4) , (2 , 5) , (2 ,6), and so on for 3, 4, 5, and 6

We can find the number of combinations by simply multiplying the amount of possible values for each dice.

Since both dices have 6 possible values, we multiply 6 by 6, and the amount of possible combinations is 36.

Now, let's determine the possibility for getting a double.

First, let's determine how many doubles we can get:

(1 , 1) , (2 , 2) , (3 , 3) , (4 , 4) , (5 , 5) , (6 ,6)

There are 6 different combinations for rolling a double.

So, our probability of rolling a double on two 6 sided dices is 6 out of 36

We can simplify that to 1 out of 6.

So the probability of rolling a double on two 6 sided dices is 1/6

In which number does the digit 4 have a value that is 10 times as great as the value of the digit 4 in 348,971? 284,796 or 327,4
Doss [256]

Answer:

The number is 492,875.

Step-by-step explanation:

Given:

A number that is = 348,971

Place value of 4 = 40,000

Place value is ten thousands.

We have to identify the number where the place value of 4 is 10 times of the given number.

Numbers given:

284,796 or 327,498 or 492,875 and 742,186.

Lets see the place value of 4 in each of the number.

⇒

  • 284,796 place value of 4 is 4,000.
  • Place value of 4 is thousands.

⇒

  • 327,498 place value of 4 is 400 .
  • Place value of 4 is hundreds.

⇒

  • 492,875 place value of 4 is 4,00,000.
  • Place value of 4 is hundred thousands.

⇒

  • 742,186 place value of 4 is 40,000.
  • Place value of 4 is ten thousands.

Notes:

Ten thousands multiplied with ten is hundreds thousand.

⇒ 10,000\times 10 =1,00,000

So,

The number which has digit 4 as hundred thousands place values is 492,875.
