Answer:
The probability that at most 38 of the 60 relays are from supplier A is P(X≤38)=0.3409.
Step-by-step explanation:
We can model this question with a binomial distribution random variable.
The sample size is n=60.
The probability that the relay come from supplier A is p=2/3 for any relay.
If we use a normal aproximation, we have the mean and standard deviation:
The probability that at most 38 of the 60 relays are from supplier A is P(X≤38)=0.3409:
Answer:
Newtons 2nd law of motion
Step-by-step explanation:
Newton’s second law of motion is closely related to Newton’s first law of motion. It mathematically states the cause and effect relationship between force and changes in motion. Newton’s second law of motion is more quantitative and is used extensively to calculate what happens in situations involving a force. Before we can write down Newton’s second law as a simple equation giving the exact relationship of force, mass, and acceleration, we need to sharpen some ideas that have already been mentioned.
Answer:system of linear equalities in one variable .
Step-by-step explanation:
Answer:
6 pencils
18 pencils
Step-by-step explanation:
Given that
36 pencils are in 6 packs
Number of packs = 6
Number of pencils = 36
Number of pencils per pack :
Number of pencils / number of packs :
36 / 6 = 6
Hence, 6 pencils per pack
Number of pencils in 3 packs :
Since 6 pencils are in a pack ;
Then, 3 packs = (3 * 6) = 18 pencils
