Mathematics
1 answer:
mina [271]3 years ago
5 0

Answer:

<em>mean absolute deviation would be 2.75</em>

Step-by-step explanation:

mean: 4 + 2 + 2 + 10 = 18/4 = 4.5

4.5 - 4 = 0.5

4.5 - 2 = 2.5

4.5 - 2 = 2.5

4.5 - 10 = 5.5

mean absolute deviation: 0.5 + 2.5 + 2.5 + 5.5 = 11/4 = 2.75

~hope this helps~

please mark me the brainliest, I would highly appreciate it :)

What are the explicit equation and domain for an arithmetic sequence with a first term of 5 and a second term of 2?
Citrus2011 [14]

The easiest way to answer this is to try all choices, plug in values for the 1st term and 2nd term then check if the answer matches with 5 and 2. (n = 1 and n = 2)

We know that n starts with 1 because that is our 1st term, we do not have 0th term, therefore that leaves us with 2 choices.

Choice 1: an = 5 − 2(n − 1); all integers where n ≥ 1

n = 1

a1 = 5 – 2 (1 – 1) = 5 – 2 (0)

a1 = 5

 

n = 2

a2 = 5 – 2 (2 – 1) = 5 – 2 (1)

<span>a2 = 3   (FALSE!)</span>

 

Choice 2: an = 5 − 3(n − 1); all integers where n ≥ 1

n = 1

a1 = 5 – 3 (1 – 1) = 5 – 3 (0)

a1 = 5

 

n = 2

a2 = 5 – 3 (2 – 1) = 5 – 3 (1)

<span>a2 = 2   (TRUE)</span>

 

Therefore the correct answer is:

<span>an = 5 − 3(n − 1); all integers where n ≥ 1</span>

HELP PLEASEEE

Answer:

Exact circumference is 7\frac{49}{150}km

Approximate circumference is 7.33 km

Step-by-step explanation:

We are given;

  • The diameter of a circle as 2\frac{1}{3} km

We are required to determine the exact and approximate circumference of the circle.

  • We know that the circumference of the circle is given by;
  • Circumference = πD, where D is the diameter

Taking π as 3.14

Circumference=3.14 (2\frac{1}{3}km)

                          =7\frac{49}{150}km

The exact circumference of the circle is 7\frac{49}{150}km

7\frac{49}{150}km=7.327 km\\                            = 7.33 km (nearest hundredth)

Thus, the approximate circumference of the circle is 7.33 km
