Step-by-step explanation:
"identity" means an operation that does nothing.
For adding numbers, adding 0 changes nothing, so 0 is the identity for addition.
For multiplication, multiplying by 1 changes nothing, so 1 is the identity for multiplication.
I believe it would be 4 1/10 ,4.104, 104/25, 4.74
Answer:
And using this formula we have this:
Then we can conclude that the probability that that a person waits fewer than 11 minutes is approximately 0.917
Step-by-step explanation:
Let X the random variable of interest that a woman must wait for a cab"the amount of time in minutes " and we know that the distribution for this random variable is given by:
And we want to find the following probability:
And for this case we can use the cumulative distribution function given by:
And using this formula we have this:
Then we can conclude that the probability that that a person waits fewer than 11 minutes is approximately 0.917
Answer:
x = 2
Step-by-step explanation:
1. distribute 9 in 9(x+1)
9x + 9 = 25 + x
2. subtract x from the right side to isolate x onto one side
8x + 9 = 25
3. subtract 9 from the left side
8x = 16
4. divide both sides by 8 to get x alone
x = 2
The question is incomplete:
If you see that gasoline costs $1.70 in Georgia and $3.40 in California, you can conclude that gasoline is twice as expensive in California as in Georgia. This conclusion from this comparison reflects the function of money as a:
-store of value
-an object with a value that varies sharply from one place to another
-medium of exchange
-unit of account
Answer:
Unit of account
Step-by-step explanation:
-Store of value refers to something that can be kept for a period of time and maintains its value in the future.
-An object with a value that varies sharply from one place to another means that products can have different prices in different places.
-Medium of exchange refers to an object with an standard value that allows you to purchase goods or services.
-Unit of account refers to a numerical unit that allows you to compare the value of products and services.
According to this, the answer is that this conclusion from this comparison reflects the function of money as a unit of account because it indicates that money works as a unit that you can use to compare the value of products, in this case the price of gasoline in different places.
