Step-by-step explanation:
(3²)³ × 3^x = 3⁷ × 3³/3¹¹
3⁶ × 3^x = 3¹⁰/3¹¹
3⁶ × 3^x = 3^-1
3^x = 3^-1 / 3⁶
3^x = 3^-1 × 3^-6
3^x = 3^-7
x = -7
The mean = 28.55, while the standard deviation is 13.16

<h3>How to calculate for the mean of the data set</h3>
We have the following numbers
24 30 4 42 40 26 23 36 12 45 29 21 34 16 47 28 32 54 19 9
The sum of these numbers is given as
571
The total numbers = 20
The mean = 571/20
= 28.55
<h3>2 = How to find the standard deviation</h3>
= (24 - 28.55)2 + ... + (9 - 28.55)/20 - 1
= 3292.95/19
= 173.31315789474
s = √173.31315789474
= 13.164845532506

Answer:
Step-by-step explanation:
The question is not clear. So, assuming that the expression you need to simplify is this one:
You need to remember a property called "Power of a power property". This property states the following:
Therefore, you need to apply the Power of a power property explained before, in order to simplify the expression provided in the exercise, multiplying the exponents inside the parentheses by the exponent outside of the parentheses. Then:
Now, you must remember that:
Finally, you get:
Six million, seven thousand, two hundred
(6,000,000) + (7,000) + (200)
Consider a shop that only sells one product: rice. For each kilogram of rice sold, a certain amount of revenue is received. Therefore, the relationship between the weight of rice sold and the amount of revenue received, is going to be a linear relationship. For example, if a kilogram of rice costs $1, then 10 kg costs $10, 100 kg costs $100, and so on. This proportion is maintained for all numbers, thus making it a linear relationship.
