Answer:
a) 0.0374 , b) 0.6500 , c) 0.3500
Step-by-step explanation:
Pr (Both consider celebrities role models) = (213/1100) x (212/1099)
= 0.0374
Pr (None consider celebrities role models) = (887/1100) x (886/1099)
= 0.6500
Pr (atleast one consider celebrities role models) = 1 - Pr (None consider role models)
1 - 0.6500 = 0.3500

Solve the system of equations using the substitution method. 2x+y=8
y=x-1
Answer:
x=3
Step-by-step explanation:
If we know that y=x-1, we can just substitute it and replace y with (x-1)
so 2x+y=8 becomes:
2x+(x-1)=8 and we simplify that into:
3x-1=8, add 1 on both sides to make it:
3x=9, divide 3 on both sides
x=3
Find the length of AB.
Answer:
We know that in a triangle, if two angles have equal measures, then the sides opposite to them are equal in length. Thus, the length of side AB is 6 units
Answer:
AB=9
Step-by-step explanation:
[tex]\frac{DC}{BC}=\frac{EC}{AC}\\ \frac{4}{3}=\frac{16}{AC}\\\\ AC=12\\\\ AB=AC-BC\\ AB=12-3=9[/tex]

The area of the hardscape is 3x^2 + 13x + 4. what is the length and width of the hardscape
Answer:
[tex](3x+1)[/tex]
[tex](x+4)[/tex]
Step-by-step explanation:
Assuming that the given surface is two-dimensional, one can simply factor the given polynomial to find the dimensions of the surface.
[tex]3x^2 + 13x + 4[/tex]
Just by looking at the polynomial, it is fairly obvious that the factors are;
[tex](3x+1)(x+4)[/tex]
One can check this by distributing, multiply every term in one of the parenthesis by every term in the other. Then combine like terms,
[tex]3x^2 + 12x + x + 4\\\\3x^2 + 13x + 4[/tex]
Without further information, it is impossible to determine which is the length, and which is the width, one just knows that the dimensions of the surface are;
[tex](3x+1)\\\\(x+4)[/tex]
Compare the 2 functions that are shown. Function A Time (sec) Distance (meters) 140 10 Function B 20 280 D = 135 30 40 50 420 560 700 Which function has a greater speed, and what is the greater speed?
