The length of a rectangle is 5 yd less than twice the width, and the area of the rectangle is 33 yd?. Find the dimensions of the rectangle.
Answer:
Step-by-step explanation:
L=2W-5
A=LW, using L from above gives you
A=(2W-5)W
A=2W^2-5W
2W^2-5W-A=0, since A=33yd^2
2W^2-5W-33=0
2W^2+6W-11W-33=0
2W(W+3)-11(W+3)=0
(2W-11)(W+3)=0, since W>0
W=11/2
W=5.5yd, since L=2W-5
L=6yd
So the dimensions are W by L, 5.5yd by 6yd

Are the events "selecting a female" and "selecting a students who has brown eyes" independent?
Answer:
No, the events are not independent.
Step-by-step explanation:
Suppose that there are two events, A and B.
Such that first happens the event A and then the event B.
If the outcome of event A affects the probabilities for the different outcomes of event B, then the events are dependent.
In this case, if we have only the event "selecting a student who has brown eyes" (at random)
The probability is equal to the quotient between the total number of students with brown eyes, and the total number of students, then this probability is:
P = 91/200 = 0.455...
Now, if we first impose the "selecting a female", now when we want to select a student with brown eyes we will look only at the female students.
In this case, there are 32 with brown eyes and a total of 90 female students, then the probability of selecting a female with brown eyes at random is:
P = 32/90 = 0.355...
So the probability is different, which means that the events "selecting a female" and "selecting a student who has brown eyes" are not independent.

What are the domain and range of f(x)=3(x−15)2+27? It is a drag an drop.
Answer 1. All real numbers
Answer 2. x≥15
Answer 3. f(x)≥15
Answer 4. x≥27
Answer 5. f(x)≥27
Answer:
1. All real numbers
Step-by-step explanation:
Simplifies to f(x) = 6x - 63, it will cross all x and y values.
The domain and range of the given function are all real numbers
We have given that,
f(x)=3(x−15)2+27
f(x)=(3x-45)2+27
f(x)=6x-90+27
What is the domain?The domain is the set of points at which the function is defined.
What is the range?
The range of a set of data is the difference between the largest and smallest values. The difference here is specific, the range of a set of data is the result of subtracting the sample maximum and minimum.
To f(x) = 6x - 63, it will cross all x and y values.

Given a tangent and a secant from an external point to the circle, then
The square of the tangent is equal to the product of the secant's external part and the entire secant, that is
8(8 + 2x + 4) = 12²
8(12 + 2x) = 144 ( divide both sides by 8 )
12 + 2x = 18 ( subtract 12 from both sides )
2x = 6 ( divide both sides by 2 )
x = 3

Sonia graphs the equations y = –x2 + 4x and y = x – 4 to solve the equation –x2 + 4x = x – 4. Her graph is shown below.
Answer:
C.–1 and 4
Step-by-step explanation:
Solving the equations y = –x² + 4x and y = x – 4
–x² + 4x = x – 4
x² - 4x + x = 4
x² - 3x = 4
x² - 3x + (3/2)² = 4 + (3/2)²
(x - 3/2)² = 4 + 9/4
= 6.25
x - 3/2 = √6.25 or x - 3/2 = -√6.25
x = 2.5 + 1.5 x = -2.5 + 1.5
= 4 = -1
