Answer:
x + 14.7
Step-by-step explanation:
Simply combine like terms. Constants go with each other and <em>x</em> terms go with each other.
6.2 + 8.5 = 14.7
x = x
x + 14.7
Since 4 is in the thousands place, it holds a value of 4,000.
Step-by-step explanation:
The ongoing arrangement of metal atoms in a three-dimensional regular ordered pattern is known in chemistry as a lattice structure. A simple model of an atom is a central atomic nucleus with electrons arranged in shells at different distances from the nucleus.
Using the Empirical Rule, approximately 95% of the area under the whole curve is in the two tails.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Hence, approximately 95% of the area under the whole curve is in the two tails.

Answer:
p = 2 p = -4
Step-by-step explanation:
Find the solution for p^2+2p-8=0
using the Quadratic Formula where
a = 1, b = 2, c = -8
p = -b ±√(b^2 - 4ac)/2a
p = -2±√(2^2 - 4(1)(-8))/2(1)
p = -2±√(4 - (-32))/2
p = -2±√(36)/2
The discriminant b^2 - 4ac > 0
So, there are two roots.
Simplifying the radical
p = -2±6/2
p = -2+6/2 = 2
and
p = -2-6/2 = -4
