Answer:
1/2, or 0.5
Step-by-step explanation:
There are 4 ways that 2 coins can fall...
Both heads (this satisfies our situation)
1st coin heads, 2nd coin tails
1st coin tails, 2nd coin heads
Both tails (this satisfies our situation)
We have 2 out of 4 ways to satisfy this situation, so our experimental probability is
P = 2/4 which reduces to
P = 1/2 , or 0.5 as a decimal
Answer: i)169y^3z^3
ii) 225a^3b^3
iii) 145x^2y^2
Step-by-step explanation:
M1= -5 , m2 = 5 inorder to get this you move the constant to the right take the root of both sides separate the solutions and you should get m1= -5, m2 =5
Answer:
initial value is 21
Step-by-step explanation:
y=mx+b
6= -3(5) +b
b=21
Problem 215
Check out the attached image. Line up the letters ABC and CDE so the first set of letters are over the second set of letters. Order is important here. Note how A corresponds to C (second C), B corresponds to D, and (the first) C corresponds to E.
We have this mapping:
A <--> C
B <--> D
C <--> E
This means...
Angle BAC corresponds to Angle DCE (red angles)
Angle ABC corresponds to Angle CDE (blue angles)
Angle BCA corresponds to Angle DEC (green angles)
It also means...
Side BC corresponds to Side DE (red sides)
Side AC corresponds to Side CE (blue sides)
Side AB corresponds to Side CD (green sides)
Check out the attached image which I hope clears up any confusion you may have. Often I think it helps to represent stuff like this in a visual way.

Problem 216
Answer: True
Since triangle ABC is congruent to triangle DEF, this means that side AB is congruent to side ED. These are corresponding sides. Since AB = 6, this means ED = 6 as well.
