Answer:

Explanation:

1 inch is 0.0833333feet

6.1 inches is 0.5083 feet

Density = mass/volume

64.6 = mass/0.50833

mass = 64.6 x 0.5083 =32.83618lb

Searches related to Probability questions - A person frequents one of the two restaurants KARIM or NAZEER, choosing Chicken’s it
balandron [24]

Answer:  

a) 0.42  

b) Independent  

c) 30%  

d) 0.88

Explanation:  

Person chooses Chicken's item : 70% = 0.7  

Person chooses fish's item : 30% = 0.3  

Visits in which he orders Afghani Chicken = 60% = 0.6  

a)

Probability that he goes to KARIM and orders Afghani Chicken:  

P = 0.7 * 0.6 = 0.42  

b)

Two events are said to be independent when occurrence of one event does not affect the probability of the other event's occurrence. Here the person orders Afghani Chicken regardless of where he visits so the events are independent.  

c)

P = 0.30 because he orders Afghani Chicken regardless of where he visits.  

d)  

Let A be the probability that he goes to KARIM:  

P(A) = 0.7 * ( 1 - 0.6 ) = 0.28  

Let A be the probability that he orders Afghani Chicken:  

P(B) =  0.3 * 0.6 = 0.18  

Let C be the probability that he goes to KARIM and orders Afghani chicken:  

= 0.7 * 0.6 = 0.42  

So probability that he goes to KARIM or orders Afghani Chicken or both:  

P(A) + P(B) + P(C) = 0.28 + 0.18 + 0.42 = 0.88

A 75-hp (shaft output) motor that has an efficiency of 91.0 percent is worn out and is replaced by a high-efficiency 75-hp motor
Naya [18.7K]

Answer:

4.536hp

Explanation:

The decrease in the heat gain of the room is determined from difference in electrical inputs:

Q = W_{shaft} (\frac{1}{n_{1} } - \frac{1}{n_{2} })\\Q = (75hp)*(\frac{1}{0.91 } - \frac{1}{0.963 })\\\\Q = 4.536 hp

How is tolerance calculated?

Answer:

hope you like it brainliest plezz

Explanation:

Tolerance equals the difference between lower and upper limit dimensions. Example; for 0.500-0.506 inch the tolerance would be 0.006 inch. BILATERAL TOLERANCE : It is a way to express tolerance by using both minus and plus variations from a given size.
