Answer:

  a.  2, 3, 6

  b.  a/b × c = 1

  c.  a = 2, b = 6, c = 3  or  a = 3, b = 6, c = 2

Step-by-step explanation:

Apparently, Erica wants to multiply a fraction by a whole number to get a result of 1. That means the fraction is the multiplicative inverse of the whole number.

__

<h3>a.</h3>

There is only one set of three unique numbers among those given such that one of them is a composite number with the other two as factors. Erica must choose 2, 3, and 6.

__

<h3>b. </h3>

If the three numbers are represented by a, b, c, Erica wants ...

  a/b × c = 1

__

<h3>c.</h3>

Multiplying the equation by b gives ...

  ac = b

Among the numbers 1–6, only 2×3 = 6 will satisfy this equation. Erica can choose either of ...

  a = 2, b = 6, c = 3   ⇒   (2/6)×3 = 1

  a = 3, b = 6, c = 2   ⇒   (3/6)×2 = 1

__

<h3>d.</h3>

1. Find the median of the following data : <br> 1) 3,1,5,6,3,4,5 <br> 2) 3,1,5,6,3,4,5,6
juin [17]

Answer:

a ) The first step -  arrange them in ascending or descending.

1,3,3,4,5,5,6

then median is to find the middle so -

the middle of this is "<u>4</u>" (there are odd numbers of numbers)

b) the first step- -  arrange them in ascending or descending.

1,3,3,4,4,4,6,6

then median is to find the middle so -

here the middle is 4 and 4 ( there are even numbers of numbers)

so you find average -

4+4/2 = <u>4 </u>

<u />

<u>these are the answers I guess. </u>

As a<br>Scientific notation<br>Express this number in standard form.<br>1.304 x 107 = ?​
aivan3 [116]

Answer:

13 040 000  

Step-by-step explanation:

To convert the scientific notation of a large number to a decimal number, move the decimal point as many places to the right as indicated by the exponent of 10.

Use zeros for placeholders as needed.

Move the decimal point seven places to the right

1.304 × 10⁷ = 13 040 000

We had to insert four zeros as placeholders.

1.304 × 10⁷ = 13 040 000
