3=−(−y+6)
Simplify:
3=−(−y+6)
3=y+−6(Distribute)
3=y−6
Flip the equation.
y−6=3
Add 6 to both sides.
y−6+6=3+6
y=9
Strike is the way that
the noise made on the hour it’s described. Each hour corresponds to a
specific strike, 1 has 1 strike, 2 have 2 strikes, 3 have 3 strikes, and so on.
The solution would be like
this for this specific problem:
1 + 2 +3 + 4 + 5 + 6 + 7 + 8 + 9 +
10 + 11 + 12 = 78 strikes for a 12 hours
78 * 2 = 156 (since a day has 24
hours)
So it
will strike 156 times per day. I am hoping that this answer has
satisfied your query and it will be able to help you in your endeavor, and if
you would like, feel free to ask another question.
Answer:
A) 90.32%
B) 90.11%
C) 81.546 miles per hour
D)77.93%
Step-by-step explanation:
Given data:
speed = 73.7 miles/hour
standard deviation = 4.77 miles /hour
a) 
= P (z< 1.31)
= 0.90320 = 90.32%
b) 
= P (-2.872< z< 1.31)
= P (z<1.31) - P(z<-2.87)
= 0.90320 - 0.00205
= 0.90115 = 90.11%
c) P(X <X) = 0.95
z = 1.645

x = 81.546 miles per hour

= P (z> -0.775)
= 0. 0.7793 = 77.93%
