Answer:

  • Mean = 16.9
  • Mode = 18
  • Median = 17.5

Step-by-step explanation:

<u>Given data:</u>

  • 18, 19, 16, 18, 14, 17, 18, 15

<u>The data in the ascending order:</u>

  • 14, 15, 16, 17, 18, 18, 18, 19

<u>The mean:</u>

  • (14 + 15 + 16 + 17 + 18*3 + 19)/8 = 16.9 (rounded)

<u>The median:</u>

  • (17 + 18)/2 = 17.5 (the average of middle terms)

<u>The mode:</u>

  • 18 (the most repeated number)

Use the formula to solve the problems.
Ber [7]

Answer:

$4,309.12

Step-by-step explanation:

The computation of the interest earned is given below:

But before that the amount would be

Amount = Principal × (1 + rate of interest)^number of years

= $6,000 × (1 + 0.07)^8

= $6,000 × 1.07^8

= $10,309.12

Now the interest earned is

= Amount - principal

= $10,309.12 - $6,000

= $4,309.12

List five rational numbers between -4/5 and -2/3 . Please tell by step by step explaintion ​

Answer:

  -0.67, -0.68, -0.69, -0.70, -0.71

Step-by-step explanation:

There are an infinite number of ways to do this.

Perhaps the simplest is to do it in decimal.

 -4/5 = -0.8

  -2/3 = -0.666... (repeating 6)

Any negative decimal number between these values will do. For example, ...

  -0.67, -0.68, -0.69, -0.70, -0.71

__

If you want to choose fractions that are evenly spaced between the given values, you can find their difference, then divide that difference into 6 parts (1 more than the number of numbers you need).

  -2/3 -(-4/5) = 4/5 -2/3 = (12 -10)/(5·3) = 2/15 . . . . length of interval

  1/6 of this difference is ...

     (1/6)(2/15) = 2/90 = 1/45

The interval end point nearest 0 is ...

  -2/3 = -30/45

so the 5 intermediate values will be that value with -1/45 repeatedly added:

  -31/45, -32/45, -33/45 = -11/15, -34/45, -35/45 = -7/9

_____

<em>Additional comment</em>

The fractions we came up with could be referred to as "5 arithmetic means between -2/3 and -4/5." There is nothing in the problem statement suggesting the values need to be evenly spaced.

When doing this in decimal, you can obtain a new value simply by adding more digits to the decimal fraction:

  -0.68, -0.685, -0.6853, -0.68531, -0.799
