Answer:
An orbital is a wave function for an electron defined by the three quantum numbers, n, ℓ and ml. Orbitals define regions in space where you are likely to find electrons. s orbitals (ℓ = 0) are spherical shaped. p orbitals (ℓ = 1) are dumb-bell shaped.

Missing Part of Question
Juice that is opened. It is known that the annual profits earned by health-drink franchises has a population standard deviation of $8,700
........
Answer:
z = 1.157
Step-by-step explanation:
Given
Annual profit as calculated = $90,300.
H0: μ = 89,000
Ha: μ > 89,000
σ = 8700
n = 60
Calculate the test statistic (z) that corresponds to the sample and hypotheses.
Test statistic (z) is calculated by
z = (x - μ)/(σ/√n)
Where x = 90,300
μ = 89,000
σ = 8700
n = 60
z = (90,300 - 89,000)/(8700/√60)
z = 1.157443298866584
z = 1.157 ----- Approximated
M(Slope)= -3/-5x
B(Y-Intercept)=-5
Mx+b(Equation)=-3/-5x-5
Answer:
A
Step-by-step explanation:
n=-7m-4
14m+2n=-8
Substitute the first equation into the second one/
14m + 2(-7m - 4) = - 8
14m - 14m - 8 = - 8
- 8 = - 8
This means than m can be anything, and therefore there are an infinite number of possible answers.
A
Answer:
B 2:1
Step-by-step explanation:
Distance between two points:
Suppose that we have two points, 
and 
. The distance between them is given by:
In this question:
The length of the segments are given by the distance between its endpoints.
Line segment AB on the coordinate plane stretches from (1,1) to (7,9).
So its length is:
Line segment CD stretches from (-2,3) to (2,6).
What is the ratio AB:CD of the lengths of these line segments?
10:5 = 2:1
So the correct answer is given by option B.
