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:Jason’s salary depends on the number of hours he works. The independent variable is the number of hours and the dependent variable is salary. Let x = the number of hours worked Let y = Jason’s salary The set of ordered pairs {(1, 10), (2, 20), (3, 30), (4, 40), (5, 50)} can be used to represent the function, assuming Jason earns $10 per hour The number of hours the train takes depends on the distance. The distance is independent and the number of hours is dependent. {(2,20)(4,40)(6,60)(8,80)(10,100)} For every 2 hours it takes 20 miles. The amount of money depends on the time worked.
Step-by-step explanation:
The answer is d is less than 6
Answer:
Your answer is 0 (zero).
<u>Step</u><u> </u><u>by</u><u> </u><u>Step</u><u> </u><u>Explanations</u><u>:</u>
<u>For</u><u> </u><u>mean</u><u>:</u>
1. Add all the numbers; which is 90
2. Divide by how numbers there are, for this case there are 6 numbers; 90/6 = 15
3. Your mean is 15
For Median:
1. Order the numbers from lest to greatest. Ex: 8, 10, 12, 18, 20, 22
2. Find the middle number(s), which are 12 &18
3. Add; 12 + 18 = 30
4. Divide; 30/2 =15
5. Your Median is 15
So now the question asks "what's the difference?" which means subtraction: 15 - 15 = 0
Answer:
one ten was traded for ten ones
Step-by-step explanation:
372 cannot be divided by 3 easily. However, 360 +12 can be divided by 3 easily, so it makes sense to trade one of the seven tens for ten ones. That will leave 6 tens, but give twelve ones.
370 +2 = 360 +12 . . . . where the "+" numbers are the numbers of ones
