So, there are 180 degrees in a triangle right? Well, we know 2 angles, 65 and 51. So add them together and you get 116. Simply subtract 116 from 180 to find the missing angle.
65 + 51 = 116
180 - 116 = 64

the first possession of each nfl game is decided by a coin toss. is this process deterministic, or truly random?
Answers
A coin toss determines the first possession of each NFL game. This process deterministic not random event because the initial coin flip only determines whether a team receives the ball now at start of the first or third quarter.
What is meant by first possession?Possession in football refers to a team keeping possession of the ball for as longer as possible in order to create opportunities for goals and prevent this same opposition from posing a threat to the team's goal.
Some key features regarding the first possession in NFL game are-
The scoring team wins if the first possession results in such a touchdown (by receiving team or a defensive team on a turnover) or a safety by the defensive team. If the receiving team is unable to score and loses possession, this same game is decided by sudden death, with the first team to score winning.Many NFL fans oppose the current overtime setup in which the winning team can elect to catch the ball, move down the field, and score, effectively ending the game without allowing the opposing team to touch the ball on offense.If the resolution of player decisions results in completely predictable outcomes, the game is deterministic. It is indeterministic to some extent if actions result in potentially chaotic outcomes.To know more about the random events, here

The range of the transformation function f(x,y)= (x+5,y-8) is (10,8), (-2,7), and (7,9) which point is in the domain
Answers
We get that the domain will be {-7, 2, 5}.
We are given a transformation function:
f ( x , y ) = ( x + 5 , y - 8 )
Also, we are given the points in this transformation function as:
(10, 8), (-2, 7) and (7, 9)
Now, we have to find the point that lies in the domain of the function.
We have:
x + 5
Also, the values of x + 5 are given as 10, -2 and 7.
For (10, 8)
x + 5 = 10
x = 10 - 5
x = 5
For (-2, 7)
x + 5 = -2
x = - 2 - 5
x = - 7
For (7, 9)
x + 5 = 7
x = 7 - 5
x = 2
So, domain is {-7, 2, 5}.
Therefore, we get that the domain will be {-7, 2, 5}.

Answers
1) 1,3,4,7 dataset has the highest variance.
1. How to find the largest variance of given set of numbers?Variability is measured by the variance. The average of the squared deviations from the mean is used to calculate it. The degree of spread in your data set is indicated by variance. The variance is greater in respect to the mean the more dispersed the data.
to find the variance,
first step is to calculate the mean Next, take each data point and square the difference after subtracting the mean. All values' squared differences are added. Next, divide the total by the number of data points. this is the process to get the variance.
a) now given that a. 7, 8, 9, 10
[tex]mean = \frac{sum \: of \: al l\:data \: points \: }{ total \: number \: of \: data\: points \: } [/tex]
[tex]mean = \frac{(7 +8 + 9 + 10) }{4} [/tex]
mean = 8.5
now, take each data point and square the difference after subtracting the mean.
[tex](7 - 8.5) {}^{2} = 2.25 \\ (8 - 8.5) {}^{2} = 0.25 \\ (9 - 8.5) {}^{2} = 0.25 \\ (10 - 8.5) {}^{2} = 2.25[/tex]
All values' squared differences are added.
2.25+0.25+0.25+2.25=5
Next, divide the total by the number of data points.
5/4 = 1.25
Hence the variance of 7,8,9,10 is 1.25
b) given that 1,3,4,7
mean = 3.75
variance = 18.75/4 = 4.68.
Hence the variance of 1,3,4,7 is 4.68
c) given that 4,2,1,0
mean= 1.75
variance= 2.1875
Hence the variance of 4,2,1,0 is 2.1875
D) given that 1,0,2,4
mean= 1.75
variance= 2.1875
Hence the variance of 1,0,2,4 is 2.1875
Therefore 1,3,4,7 dataset has the highest variance.

Gabriels in southern California, grow as much as 1.0 cm within a year. If a
year is considered to be exactly 365 days, what is the speed at which the San
Gabriel Mountains grow in kilometers per hour?
Answers
Using proportions, the San Gabriel Mountains grow 0.00000000114 km/h.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For this problem, we have that:
Each cm has 0.00001 km.Each day has 24 hours, hence a year has 365 x 24 = 8760 hours.Hence the speed is:
0.00001/8760 = 0.00000000114 km/h.

Distance can be defined as the amount of ground covered or walked by a physical object, regardless of its direction, starting or ending point.
How to calculate the total distance?In order to determine the total distance walked by this person, we would simply add each of the distances recorded together as follows:
Total distance = 3 + 7 + 4 + 5 + 4
Total distance = 23 miles.
How to determine the total displacement vector?In order to determine the total displacement vector, we would add all of the vectors together as follows:
3 miles East = <5, 0>
7 miles Southeast = <7/√2, -7/√2> or <7cos45°, -7sin45°>
4 miles South = <0, -4>
5 miles Southwest = <-5/√2, -5/√2> or <-5cos45°, -5sin45°>
4 miles East = <4, 0>
Total displacement vector = <5 + 7/√2 + 0 - 5/√2 + 4, 0 - 7/√2 - 4 - 5/√2 + 0>
Total displacement vector = <9 + 2/√2, -4 - 12/√2>
Total displacement vector = <9 + 1.41, -4 - 8.49>
Total displacement vector = 10.41i - 12.49.
If this person walked straight home, the total distance walked is giving by the resultant of the above displacement vector:
Total distance = √[10.41² + (-12.49)²]
Total distance = √[108.37 + 156.00]

Answers
Your question was incomplete. Please refer the content below:
If 6 bales are needed to feed 40 head of cattle, how many bales are needed to feed 50 head of cattle?
By using unitary method, we get that 7.5 bales are need to feed the 50 heads of cattle.
We are given that:
6 bales are need to feed the 40 heads of cattle.
We need to find out that how many bales will be needed to feed the 50 heads of cattle.
Here, we will be using the unitary method.
So, 40 heads need = 6 bales
1 head needs = 6/40 bales
1 head needs = 3 / 20 bales.
So, 50 heads will need:
50 heads will need = 3 / 20 × 50 bales
50 heads will need = 3 / 2 × 5 bales
50 heads will need = 7.5 bales.
Therefore, by using unitary method, we get that 7.5 bales are need to feed the 50 heads of cattle.

The relationship between the values of the two 4s in the weight of the potatoes is that the first number is 10 times the second 4.
How to illustrate the information?In this case, the weight of a potato is given as 3.441g.
It should be noted that the first 4 is in the tenth place and is written as 0.4.
On the other hand, the second 4 is in the hundredth place. The value is 0.04.
Therefore, the relationship between the numbers will be:
= 1/10 × 1/10 = 1/100
Therefore, the relationship between the values of the two 4s in the weight of the potatoes is that the first number is 10 times the second 4.

Solve system of equations.
1/3x-3 y=-4
x-9 y=-12
Answers
The system of equations involving 1/3x - 3y = -4 and x - 9y = -12 has infinite number of solutions.
A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.
There are three methods that can be used to solve system of linear equations.
1. Elimination
2. Substitution
3. Graphing
Using substitution method, given two linear equations in x and y,
1/3x - 3y = -4 (equation 1)
x - 9y = -12 (equation 2)
Using the second equation, find the value of one variable, lets say x, in terms of the other.
x - 9y = -12 (equation 2)
x = 9y - 12
Substitute the equation of x to the first equation.
1/3x - 3y = -4 (equation 1)
1/3(9y - 12) -3y = -4
3y - 4 - 3y = -4
Combining the all terms containing the variable y on one side and the constants on the other side of the equality, and solving for y.
3y - 3y = -4 + 4
0 = 0
Since we did not get unique values for x and y, check if one of the equations is a simplified form of the other. Multiply the first equation with 3.
1/3x - 3y = -4 (equation 1)
3(1/3x - 3y) = 3(-4)
x - 9y = -12
Since this new equation is the same with the second equation, this means that the lines of the two equations are the same(overlapping). Hence, the system of equations has infinite number of solutions.
