A fair coin is tossed three times. What is P(tossing at least two tails)?
A: one eighth
B: one fourth
C: three eighths
D: one half
Answers
Answer:
one eighth
Step by step explanation:
Let us mark H for Heads and T for Tails.
The coin is flipped three times; the total
number of outcomes = 2 * 2 * 2 = 8 .
Sample Space (| Omega|)=\ (H, H, H), (H, H, T) ,(H,T,
H ),(H,T,T),(T,H,H),(T,H,T),(T,T,H),(T,T,T)\
= 8
Let X be the probability of getting all tails: X
= \{(T, T, T)\}
=> |X| = 1
P(X) = IXI/IQI = 1/8.
Thus, the probability of flipping a coin three times and getting 3 tails is 1/8.
Answer:
D: one half
Step-by-step explanation:
You want the probability of tossing at least two tails when a fair coin is tossed 3 times.
OutcomesThe outcomes from the tosses will be one of ...
TTT, TTH, THT, THH, HTT, HTH, HHT, HHH
Of the 8 possible outcomes, the 4 that are highlighted have at least 2 tails.
D: The probability of tossing at least 2 tails is 4/8 = 1/2.

Answer: -1, 2
Step-by-step explanation: y = 3y - 7+1
y = 3y - 6
6 = 3y
y = 2
Now, substitute 2 back into the equation to find out x and get (-1, 2)
The solution of the system above can be solved using substitution method of solving equations. The value of y = 3, X = 4.
How to solve the system of equations?The equations given ;
X = 3y -7 ---> equation 1
y = X + 1 ---> equation 2
Substitute equation 1 into equation 2
That is;
y = 3y - 7 + 1
y - 3y = -7+1
-2y = -6
y = -6/-2
y = 3
Substitute y = 3 into equation 2;
3 = X - 1
X = 3+1
X = 4

Are the ratios
25/45
and
15/27
proportional? Explain.
Answers
Answer:
Yes
Step-by-step explanation:
First ration we will divide by 5 (both numbers) and second one by 3 (again both numbers).
First ratio becomes (25:5)/(45:5) = 5/9
Second ratio becomes (15:3)/(27:3) = 5/9
Since we can simplify them in that way that both are the same that means they are proportional.
because when we make them smaller like 25/45 divide by 5 and 15/27 divide by 3 it forms 5/9
Answer:
Yes
Step-by-step explanation:
If you divide 25/45 by 5 you get 5/9
Then you divide 15/27 by 3 you also get 5/9
Since both are equal to 5/9 they are proportional.

In the diagram below, what are AC and BC?
Answers
Answer:
54 degrees
Step-by-step explanation:
a to c is 45 degrees, and b to c is about 9, so add them together and get 54
Answer:
Step-by-step explanation:
This can be solved using the law of sines.
First find angle b which is 180 - (30 + 45) = 180 -75 = 105°
[tex]\frac{sin C}{c}[/tex] = [tex]\frac{sin B}{b}[/tex]
[tex]\frac{sin 45}{10}[/tex] = [tex]\frac{sin 105}{b}[/tex]
Cross multiply at this point
sin 45 (b) = sin 105 (10)
.707106b = .96592 (10)
.707106b = 9.6592
divide both sides by .707106
b = 13.66 this is the length of AC
Next solve for BC which is a in the equation.
[tex]\frac{sin c}{c}[/tex] = [tex]\frac{sin A}{a}[/tex]
[tex]\frac{sin 45}{10}[/tex] = [tex]\frac{sin 30}{a}[/tex]
Cross mulitply
sin 45 (a) = sin 30 (10)
.707106 a = .5 (10)
.707106 a = 5
divide both sides by .707106
a = 7.07 which is segment BC
so AC = 13.66 and BC = 7.07
