Consider the glven solids with the dimensions shown. Which solids are similar?
A. only figure 1 and figure 2
B. only figure 1 and figure 3
C. only figure 2 and figure 3
D. all three figures
Answers
Answer:
A) only figure 1 and figure 2
Step-by-step explanation:
Answer: Choice A) only figure 1 and figure 2
===========================================================
Explanation:
Let's assume that figure 2 is similar to figure 3.
If this is the case, then the horizontal portions would divide to 30/15 = 2, showing that figure 3 has sides that are twice as long compared to figure 2. But then notice that the vertical sides divide to 36/24 = 1.5, which doesn't match with the previous result of 2.
Figures 2 and 3 cannot be similar for that reason.
Also, figures 1 and 3 are not similar either. Note the horizontal portions divide to 30/10 = 3 while the vertical portions divide to 36/16 = 2.25; the results 3 and 2.25 don't match.
We eliminate answers B, C and D. The only thing left is choice A.
-------------------
To verify choice A is true, we divide each corresponding piece like so
Horizontal: 15/10 = 1.5Vertical: 24/16 = 1.5Slanted: 12/8 = 1.5Each division leads to the same result of 1.5, meaning that figure 2's side lengths are 1.5 times longer than the corresponding side lengths of figure 1. So this confirms that figure 1 is similar to figure 2.

[tex](x - 7)(x - 5) = 3[/tex]
Answers
Answer:
x = 4, x = 8
Step-by-step explanation:
Given
(x - 7)(x - 5) = 3 ← expand factors using FOIL
x² - 12x + 35 = 3 ( subtract 3 from both sides )
x² - 12x + 32 = 0 ← in standard form
(x - 4)(x - 8) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x - 8 = 0 ⇒ x = 8

Sonia graphs the equations y = –x2 + 4x and y = x – 4 to solve the equation –x2 + 4x = x – 4. Her graph is shown below.
Answers
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

Answers
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?
Answers
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.
