Answer:
The data in statistics is generally supposed to deviate or vary from the mean. Standard deviations of 1, 2, and 3 are commonly used to calculate variability according to the empirical norm. In a normal distribution, we estimate 68 percent, 95 percent, and 98 percent of the data to be within 1, 2, and 3 standard deviations of the mean, respectively. This implies that the given percentage of data will lie within an interval of less than or greater than the standard deviation. If the values within a given standard deviation from the mean are standardized, the z value will always be equal to or less than the given standard deviation.
We should look at a program that aims to help people get out of poverty by using the standard deviation principle. The aim of the program is to provide free seeds to poor people who have been suffering from low yields due to the use of local seeds. If we use the definition of one standard deviation of the mean, or 2 and 3, we will favor the majority of people, but we will leave the poorest people in society behind.
Answer: x = 2/3
Step-by-step explanation:
<em>Add all sides.</em>
2x-2 + 2x - 2 + x + x =
6x - 4
<em>Put " = 0 "</em>
6x-4 = 0
Add 4 to both sides.
6x-4 = 0
+4 = +4
-------------------
6x=4
You get 6x = 4 because the 4 on the left side of the equals sign cancelled out!
<em></em>
<em>NOW DIVIDE 6 FROM BOTH SIDES</em>
6x = 4
/6 /6
-----------
x= 4/6
<em>SIMPLIFY / REDUCE FRACTION</em>
4/6 divided by 2 = 2/3
2/3 is the answer !
X^2 + 8x + 7 = 0
x^2 + 7x + x + 7 = 0
x(x + 7) + 1(x + 7) = 0
(x + 7) (x + 1) = 0
x = -7 or x = -1
Arianna sold for $ 299.6
<em><u>Solution:</u></em>
Given that, Part of Arianna’s earnings are based on a 5% commission rate
At the end of the day arianna earned 14.98 in commission
Therefore,
Commission earned = $ 14.98
Commission rate = 5 %
Let "x" be the amount that Arianna sell that day
Therefore, according to question,
5 % of amount earned = 14.98
5 % of "x" = 14.98
<em><u>Solve the above equation for "x"</u></em>
Thus arianna sold for $ 299.6
