Answer:
a) linear pair angles: 1&2, 2&3, 3&4, 1&4... etc (any angles that are adjacent, or right next, to each other that add up to be 180 degrees)
b) All linear pair angles are adjacent angles but not all adjacent angles are linear pairs. So pick any linear pair angle you got because they will always be adjacent. (1&2, 2&3, 3&4, 1&4... etc)
c) vertically opposite angles: 1&3, 2&4, 5&7, 6&8, 9&11, 10&12

2.5 cm of snow fall on average each hour.
What is average?
The average formula is also known as the arithmetic mean, which is the ratio of the sum of all given observations to the total number of observations. Thus, using the average formula, the arithmetic mean for any sample of data can be calculated.
The average formula for a given set of data or observations can be expressed as:
Average Formula:
Average = (Sum of Observations) ÷ (Total Numbers of Observations)
Given:
The number of millimeters that fell throughout the course of the period divided by the number of hours is the mean hourly snowfall.
At 5:00 PM,
There are 4 hours from 6 PM to 9 PM.
So, there is 2 millimeters of snowfall as of 5 p.m.
and, 12 millimeters of snowfall as of 9 p.m.
Then, the accumulation of snow rises by
=12-2
= 10 cm in those four hours.
Thus, on an average the snow fall at rate
= 10/4
= 2.5
Hence, 2.5 cm of snow fall on average each hour.

Solve for n:
24 = 3n - 15
Answers
Answer:
N = 13
Step-by-step explanation:
Move all terms containing n to the left, all other terms to the right.
Add '-3n' to each side of the equation.
24 + -3n = -15 + 3n + -3n
Combine like terms: 3n + -3n = 0
24 + -3n = -15 + 0
24 + -3n = -15
Add '-24' to each side of the equation.
24 + -24 + -3n = -15 + -24
Combine like terms: 24 + -24 = 0
0 + -3n = -15 + -24
-3n = -15 + -24
Combine like terms: -15 + -24 = -39
-3n = -39
Divide each side by '-3'.
n = 13
Simplifying
n = 13

Answer:
P (X = i) = (i + 9 _ 9) (1/2)^(i + 10)
Step-by-step explanation:
Range of X = {0, 1, 2, 3......10}
P (X = i) = P (NB (10, ½) i = 10)
P (X = i) = (i + 9 _ 9) (1/2)^10 (1/2)^(1+10-10)
P (X = i) = (i + 9 _ 9) (1/2)^10 (1/2)^1
P (X = i) = (i + 9 _ 9) (1/2)^(i + 10)

Answers
Answer:
Samantha will earn $1,150 on the 7th day.
Step-by-step explanation:
Linear Modeling
It consists of finding the equation of a line that represents the data provided in a specific situation.
Tina's (or Samantha's) earnings are $550, x, $750,... where x is an unknown amount for the second day of her new restaurant.
The earnings continue to increase at the same rate until the 7th day. We must find the earnings for that last day.
The linear model can be found in several ways. We'll use the slope-point form of the line, finding first the slope and then the y-intercept.
The equation of the line in slope-intercept form is:
y=mx+b
Being m the slope and b the y-intercept.
1) Find the slope
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have the points (1,550) and (3,750), thus:
[tex]\displaystyle m=\frac{750-550}{3-1}=100[/tex]
2) Get the equation of the line
Substituting into the equation of the line, we get:
y=100x+b
Select the point (1,550), substitute into the above equation, and solve for b:
550=100(1)+b
Solving:
b=450
Thus we complete the equation of the linear model:
y=100x+450
3) Substitute 7 for x
y=100(7)+450
y=1,150
Samantha will earn $1,150 on the 7th day.

Answers
Answer:
The score separating the bottom 47% from the top 53% is 112.8
Step-by-step explanation:
Let X denote the random variable whose values are normal with a mean of 114.5 and a standard deviation of 23.
Compute the 47th percentile as follows:
[tex]P(X<x)=0.47\\\\P(\frac{X-\mu}{\sigma}<\frac{x-114.5}{23})=0.47\\\\P(Z<z)=0.47[/tex]
The corresponding z-value is,
z = -0.075
*Use the z-table.
Compute the value of x as follows:
[tex]\frac{x-114.5}{23}=-0.075\\\\x=114.5-(0.075\times 23)\\\\x=112.775\\\\x\approx 112.8[/tex]
Thus, the score separating the bottom 47% from the top 53% is 112.8
