18.386 rounded to the nearest hundredth would be 18.39
The value of the expression is 0.0265. Using exponents and power rules, the required value is calculated.
<h3>What are the exponent and power rules?</h3>
The important exponent and power rules are:
- a⁻ⁿ = 1/aⁿ; negative exponent
- (ab)ⁿ = aⁿ × bⁿ; power of a product rule
- aⁿ × aˣ = aⁿ⁺ˣ; multiplication rule
- aⁿ/aˣ = aⁿ⁻ˣ; division rule
- ; fractional exponent
<h3>Calculation:</h3>
The given expression is
Using calculator: = 0.0265
Applying the exponent rule for evaluating the given expression:
Applying the negative power rule;
I.e., a⁻ⁿ = 1/aⁿ
⇒
Applying fractional exponent rule;
I.e.,
⇒
⇒ 1/
⇒ 1/37.6077
⇒ 0.0265
Therefore, the value of the given expression is 0.0265.

Answer:
Hey stu132057, your the MAD for the data set given is
Step-by-step explanation:
Step 1: Find the mean of the data: (14+13+16+12+17+21+26)/7 = 17
Step 2: Find the difference between each data and mean:Difference between 14 and 17 is 3
<u>Difference between 13 and 17 is 4</u>
<u>Difference between 16 and 17 is 1</u>
<u>Difference between 12 and 17 is 5</u>
<u>Difference between 17 and 17 is 0</u>
<u>Difference between 21 and 17 is 4</u>
<u>Difference between 26 and 17 is 9</u>
Step 3: Add all the differences: 3+4+1+5+0+4+9 = 26
Step 4: Divide it by the number of data:26/7 = 3.7
So, the MAD = 3.7
