Answer
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 2
3 miles ÷ 2
2 hours ÷ 2
=
1.5 miles
1 hour
=
1.5 miles
hour
= 1.5 miles per hour
Solution :
Faulty electrical connects = P(A) = 0.80
Mechanical defects = P(B) = 0.92
Mechanical defects are related to loose keys = P(C/B) = 0.27
Improper assembly = P(D/B) = 0.73
Defective wires = P(E/A) = 0.35
Improper connections = P(F/A) = 0.13
Poorly welded wires = P(G/A) = 0.52
Now, the probability due to loose keys = 0.27 x 0.92 = 0.2484
Improperly connected = 0.13 x 0.80 = 0.1040
Poorly welded wires = 0.52 x 0.80 = 0.4160
So, the probability that a failure is due to improperly connected or poorly welded wires = 0.1040 + 0.4160
= 0.5200
Answer:
16h^2-4h-42
Step-by-step explanation:
4h times 4h is 16h^2
4h times -7 is -28h
4h times 6 is 24h
6 times -7 is -42
Combine like terms to get 16h^2-4h-42
That’s what I got I didn’t know how to type it so I just took a photo
People don't actually know this, but it isn't 4, it's 22. If Base+ball is Baseball, then 2+2 is 22
I hope this helps!
