Explanation:
The diagram shows that PT = 4 and QR = 5. Since QR is a radius of the circle, this means that the other radii segments TR and RS are also 5 units long.
Note how PR = PT+TR = 4+5 = 9, and how this segment is the hypotenuse for the right triangles PQR and PRS.
Picking either triangle, we have one known leg of 5 units (the radius mentioned earlier) and the other is unknown. The unknown leg is tangent to the circle, and recall that a tangent segment is always perpendicular to the radius at the point of tangency. So that's why we have right triangles.
Apply the pythagorean theorem to find the length of PQ and PS (both are the same length)
a^2 + b^2 = c^2
a^2 + 5^2 = 9^2
a^2 + 25 = 81
a^2 = 81 - 25
a^2 = 56
a = sqrt(56)
a = sqrt(4*14)
a = sqrt(4)*sqrt(14)
a = 2*sqrt(14)
The exact length of PQ and PS is 2*sqrt(14) units.
---------
We have enough to find the perimeter of quadrilateral PQRS. We add up the exterior sides. That means we ignore the interior segment PR.
perimeter = PQ+QR+RS+SP
perimeter = 2*sqrt(14)+5+5+2*sqrt(14)
perimeter = 10+4*sqrt(14)

A doctor has invented a relaxation method that he
thinks will relieve anxiety and help students score
higher on exams. He wants to test the method on a
group of statistics students to see if it improves their
scores on the final exam. All of the students have
volunteered to participate.
What is the response variable for the experiment?
Answer:
Exam score
Step-by-step explanation:
The response variable also known as the d pendent variable, is simply the variable we intend to measure based in a set of variables (independent variables or explanatory variables) which might cause it to change. For instance, the scenario above aims to look into how a certain relaxation method will affect the exam score, here, the variable we intend to measure is the response variable which is exam score. The exam score is affected by the impact the relaxation method has on the student, hence, the relaxation method is the independent or explanatory variable.

Step-by-step explanation:
sin x = 12/16 = 0.75
x = arc sin 0.75 = 48.6°
cos x = 36/40 = 0.90
x= arc cos 0.90 = 25.8°
cos x = 10/15 = 0.6667
x= arc cos 0.6667 = 48.2°
tan x = 30/18 = 1.6667
x = arc tan 1.6667 = 59.0°

Step-by-step explanation:
find the volume
find 80% of whats left
divide by 1.75 (gas price)
sorry if its wrong but im human
will give you the steps but try to do the problem by yourself.
Start by finding the volume of the tank
Multiply 1.75 ft and 1.25 ft then covert the sum to inches by multiplying it by 12.
Then multiply that amount by the ll inches and you have the volume.
Since the tank is 20% full divide the volume by five, take the number you get from that and subtract it from the origanl volume.
Now you have the amount you need to fill.
Since it is 3.
Divide the amount you need to fill by 77 and you get the cost to fill the tank.

What is the shape of the graph of the function?
h(t)=0.6⋅3.2^t
Answer:
A
Step-by-step explanation:
Here the base (3.2) is greater than 1 and the exponent (t) is positive. Thus the graph will have shape A.
The correct graph for the given function h(t)=0.6×[tex]3.2^{t}[/tex] will be upward increasing so option (A) will be correct.
How to plot a graph?A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
After that, we need to substitute the values of x's and y's into the coordinate geometry.
Given function is h(t)=0.6×[tex]3.2^{t}[/tex]
As t is increasing then the term [tex]3.2^{t}[/tex] will also go to increase since 3.2 is greater than 1.
Hence the value of the graph will go to increase as x increases so it is clear that option (A) will be correct.

Answer:yˆ=−0.175x2−3.786x+121.119
look at picture
Step-by-step explanation:
The quadratic regression equation for the data set is:
y^ = -0.175x²-3.786x+121.119
What is Quadratic Regression Equation?Quadratic regression is the process of determining the equation of a parabola that best fits a set of data. This set of data is a given set of graph points that make up the shape of a parabola. The equation of the parabola is y = ax² + bx + c, where a can never equal zero.
According to the given problem,
Let us choose any value of x,
x = 10
For this value of x we can see that the respective value of y= 50
Substituting the value of x in the equations to see which equation satisfies the value of y as 50.
Substituting the value of x in the equation:
y^ = -0.175x²-3.786x+121.119
y^ = 50
Hence, we can conclude that y^ = 0.175x² - 3.786 + 121.119 is the quadratic regression equation for the given data set.

A five question multiple choice test has 4 choices for each question and only 1 correct answer each. What is the probability of guessing at least 3 out of the 5 questions correctly?
Answer:
Prob = 13/1024 = 0.0127
Step-by-step explanation:
Prob {A correct answer} = Correct option / Total options = 1/4
Prob {A wrong answer} = Wrong options / Total options = 3/4
Prob [3 answers correct] = P (3 correct ,& 2 wrong) or P (4 correct ,& 1 wrong) or P (5 correct, & no wrong)
= [ (1/4) x (1/4) x (1/4) x (3/4) x (3/4) ] + [ (1/4) x (1/4) x (1/4) x (1/4) x (3/4) ] + [ (1/4) x (1/4) x (1/4) x (1/4) x (1/4) ]

Step-by-step explanation:
We know that the common ratio is 1.75 which means that the data would go up by $1.75 each time and then an additional of 6.25 is also there. Hence, 1.75 would be the slope and 6.25 would be the intercept of the equation.

Caroline has 12 cherries and 13 strawberries. What percentage are the cherries?
Answer:
12/25=48%
Step-by-step explanation:
total=denominator=12+13=25
numerator=no of cherries=12
12/25=x/100
1200=25x
x=48%
A percentage is a number or ratio that represents a fraction of 100.
Percentage formula = (Required number / Total number) x 100
The percentage of cherries is 48%.
What is a percentage?A percentage is a number or ratio that represents a fraction of 100.
Example:
50% = 50 /100 = 1/2
25% = 25/100 = 1/4
We have,
Number of cherries = 12
Number of strawberries = 13
The total number of fruits:
= 12 + 13
= 25
Percentage formula = (Required number / Total number) x 100
The percentage of cherries:
= (Number of Cherries / Total number of fruits) x 100
= (12 / 25) x 100
[ 25 x 4 = 100 ]
= 12 x 4
= 48%
Thus,
The percentage of cherries is 48%.
