According
to the empirical rule, if the data form a "bell-shaped" normal
distribution, approximately 99.7 percent of the observations will be contained
within 3 standard deviations around the mean.

To add, a bell curve is used to describe the mathematical concept called
normal distribution, sometimes referred to as Gaussian distribution. </span>
Answer:
Step-by-step explanation:
1) Split the second term in into two terms.
1- Multiply the coefficient of the first term by the constant term.
to -8 and multiply to -−20?
2 and −10
3 - Split -8x as the sum of 2x and -10x.
2) Factor out common terms in the first two terms, then in the last two terms.
3) Factor out the common term .
4) Solve for .
1 - Ask: When will (2x+1)(2x-5) equal zero?
When 2x + 1 = 0 or 2x - 5 = 0
2 - Solve each of the 2 equations above.
Correct question:
Beth is making a beanbag seat in the shape of a cube. Each side of the seat is 2 feet long. Beth needs to find the volume of the seat so that she can buy the correct amount of beans. Beans are sold in bags that hold 2³ feet of beans. How many bags of beans should Beth buy?
Answer:
Beth should buy 4 bags of beans.
Step-by-step explanation:
Since Beth is making a bean bag seat in the shape of a cube, we already know the bean bag seat is a cuboid.
Also, we are asked to find the volume of a cuboid, and the volume of a cuboid is given as the product of all dimensions of the cuboid.
Therefore the volume of the seat is expressed as
V = 2 * 2 * 2
V = 8
To find the number of bags she needs, we have:
Beth needs to buy 4 bags of beans

Answer:
x = -2/3
Step-by-step explanation:
<u><em>Given:</em></u>
<u><em></em></u>
<u><em>Solve:</em></u>
<em>Multiplying both sides by 2:</em>
<em />
⇒
Distribute:
Add 8 to both sides:
⇒
Subtract 6x from both sides:
Divide both sides by -12
⇒
