What is the place value of a digit in a number?

The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.

Identification of the place value of a digit in a number:

  • The place values on the left of the decimal point start as ones, tens, hundreds, and so on.
  • The place value on the right of the decimal point starts from the point and goes to the right as tenths, hundredths and so on
  • The tens mean multiply by 10
  • The tenth means the tenth part of that digit which is that digit divided by 10

The given number 40,897 in the expanded form can be written as,

40,897

= (4×10,000) + (0×1,000) + (8×100) + (9×10) + 7

= 40,000 + 0 + 800 + 90 + 7

= 40,000 + 800 + 90 +7

Hence, the given number 40,897 in the expanded form is written as 40,000 + 800 + 90 +7.

the least common denominator of 2 fractions is 12 if you add the two denominators their sum is 7 what are the denominators

Answers

Possible options are  1 7, 2 5, 3 4
it would be 3 and 4 since they are the only two in here that have the least common denominate of 12. 5 isn't divisible by 12, 7 isn't either, so that only leaves 3 and 4 and they worked since 3*4 does equal 12.

Use the given information to state the conclusion about the null hypothesis H0. Assume a significance level of 0.01. Original​ claim: The percentage of settled medical malpractice suits is.at least 50% The hypothesis test results in a P-value of 0.012.

Answers

Answer: We reject the null hypothesis.

Step-by-step explanation:

Given : Significance level :

Let p represents the proportion of the settled medical malpractice suits.

Given claim : The percentage of settled medical malpractice suits is at least 50%.

i.e.

Thus,

We know that when the calculated p-value is less than the significance level () then we reject the null hypothesis, if p-value is greater than the significance level () then we do not reject.

Now , the calculated value 0.012 is less than the 0.01, so we reject the null hypothesis.
