the international shark attack file recorded the number of shark attacks between 1837 and 2016 for 8 different u.s. states.
what is the mean number of shark attacks over these states?
4,8, 5, 13,3,4, 1, 10
The mean of the data given 4, 8,5, 13, 3, 4, 1, 10 shows number of shark attacks over 8 different states is 6.
As given,
Number of different states 'n'= 8
Number of sharks attacks for 8 different states
[tex]x_{i}[/tex] = 4, 8,5, 13, 3, 4, 1, 10
Mean = [tex]\frac{\sum x_{i} }{n}[/tex]
= (4+ 8+ 5 + 13 + 3 + 4 + 1 + 10) /8
=48 /8
=6
Therefore, the mean of the data given 4, 8,5, 13, 3, 4, 1, 10 shows number of shark attacks over 8 different states is 6.

Step-by-step explanation:
Let (-4,-4) be a point on the terminal side of theta in standard position. find exact values of the six trigonometric functions of theta
The six trigonometric functions of theta for the point (-4, -4) is
sin Θ = -1/√2
cos Θ = -1/√2
tan Θ = 1
cosec Θ = -√2
sec Θ = -√2
cot Θ = 1
Trigonometric Functions:
Trigonometric functions are defined as the functions of an angle of a triangle. It means that the relationship between the angles and sides of a triangle.
The six trigonometric functions are,
Sin Θ =Opposite/Hypotenuse
Cos Θ = Adjacent/Hypotenuse
Tan Θ = Opposite/Adjacent
Sec Θ = Hypotenuse/Adjacent
Cosec Θ = Hypotenuse/Opposite
cot Θ = Adjacent/Opposite
Given,
Let (-4,-4) be a point on the terminal side of theta in standard position.
Here we need to find the exact values of six trigonometric functions.
Here the give point (-4,-4) represents the values of (opposite, adjacent).
So, the opposite = -4
and adjacent = -4
Now we have to find the hypotenuse of the point,
For that, we have to use the Pythagoras theorem,
hypotenuse = √oppostie² + adjacent²
Therefore,
=> hypotenuse = √(-4)² + (-4)²
=> hypotenuse = √16 + 16
=> hypotenuse = √32
it can be written as,
=> hypotenuse = √2 x 16
=> hypotenuse = 4√2
Now the six trigonometric functions are based on the formula,
sin Θ = -4/4√2 => sin Θ = -1/√2
cos Θ = -4/4√2 => cos Θ = -1/√2
tan Θ = -4/-4 => tan Θ = 1
cosec Θ = 4√2/-4 => cosec Θ = -√2
sec Θ = 4√2/-4 => sec Θ = -√2
cot Θ = -4/-4 => cot Θ = 1
So, all the six trigonometric values are identified.

An angle is denoted by the angle symbol ∠ and the three letters representing the name of the angle.
An angle is denoted by the angle symbol ∠ which is then being followed by three letters that will represent the points that form an angle.
Lets say for example, the expression ∠ABC will mean that “the angle is formed by the points A, B and C”
where the vertex of the angle is at the point B as it is in the middle.
Angles can also be of different types like:
An Acute Angle which means an angle is less than 90 degrees.
A Right Angle which means an angle which is exactly 90 degrees.
An Obtuse Angle which is an angle more than 90 degrees and less than 180 degrees.
A Straight Angle which is an angle that is exactly 180 degrees.

Mr. Price deposited $170 in his bank. The number of $5 bills was 3 times the number of
$10 bills, and the number of $1 bills was 30 more than the number of $5 bills. How many
bills of each type did he deposit?
Mr. Price deposited a $10 bill for $50, a $5 bill for $75, and a $1 bill for $45.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
We have been given that the number of $5 bills was 3 times the number of $10 bills
Let the number of $10 bills would be x
As per the given condition,
$10 = x
$5 = 3x
$1 = 3x+30
Since he deposited $170 in his bank.
So 10x + 5(3x) + 1(3x+30) = 170
⇒ 25x+3x+30=170
⇒ 28x=140
⇒ x = 5
Therefore, $10 for $50
So 3x = 15, $5 for $75
So 3x+30 = 45, $1 for $45
Hence, he deposited a $10 bill for $50, a $5 bill for $75, and a $1 bill for $45.

Z is a standard normal random variable. what is the value of z if the area to the right of z is 0.0122?
The value of z = 2.25
Given that z is a standard normal random variable.
Now the area under a standard normal curve between two z -values gives the probability of z lying between these two z-values.
Given that the area to the right of z = 0.0122
That is probability that the standard normal random variable lies after z = 0.0122
Total probability = 1
Therefore half the area under the standard normal curve = 0.5
Therefore, 0.5 - 0.0122 = 0.4878
We will find the corresponding z-value for this probability value from the normal tables. This is because normal tables gives area between two standard normal variables.
The table value corresponding to 0.4878 = 2.25
Therefore, z -value = 2.25

The value of x is 27°, m∠=PQY=101° and m∠RQY=79°.
Given that, m∠PQY= 4x-7 and m∠RQY = 2x+25 are linear pairs of angles.
What are linear pairs of angles?Linear pairs of angles are formed when two lines intersect each other at a single point. The angles are said to be linear if they are adjacent to each other after the intersection of the two lines. The sum of angles of a linear pair is always equal to 180°.
Now, m∠PQY+m∠RQY=180°
⇒4x-7+2x+25=180°
⇒6x+18=180°
