Answer:
8x +5y
Step-by-step explanation:
As with any purchase, the extended amount of the bill for an item is the product of the number of items bought and the price of each of them. The total bill is the sum of the extended amounts.
On Samuel's first visit he paid ...
3x +2y . . . . . dollars for apples and spinach
On Samuel's second visit, he paid ...
5x + 3y . . . . . dollars for apples and spinach
Then the total he spent was ...
(3x +2y) +(5x +3y) = (3x +5x) +(2y +3y) = 8x +5y
10% of x= 38 $
10x/100=38
x=38*100/10
x=380 $
Answer:
1,331in^3
Step-by-step explanation:
Answer:
a) 220
b) 10
c) 4.55% probability that the selected group will consist of all women.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the people are selected is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
a. In how many ways can three people be selected from this group of twelve?
b. In how many ways can three women be selected from the five women?
Three women, from a set of 5. So
c. Find the probability that the selected group will consist of all women.
Desired outcomes:
3 women from a set of 4. So
Total outcomes:
3 people, from a set of 12. So
Probability:
4.55% probability that the selected group will consist of all women.
Answer: y=3x-7
Step-by-step explanation:
First you have to get the equation in slope intercept form by moving x over then dividing by -1 because y cannot be negative
Then since you're trying to find the line that is parallel you use the same slope which is 3x
You then plug in the points which is 2=3(3) + b for you are trying to find teh y intercept
You then solve as normal and get y=3x-7
I am pretty sure this is correct
