Answer:
(0, -2)
Step-by-step explanation:
The y-intercept is where the graph crosses the y-axis when x = 0. As shown in the graph, when x = 0, y = -2, so your answer is (0, -2).
Answer:
1.9
Step-by-step explanation:
The MAD is found by <em>finding the mean, then finding how far each number is to the mean, then finding the mean of that.</em>
The mean is: <em>(1 + 8 + 3 + 1 + 3 + 3 + 7 + 5 + 1 + 3)/10</em> = 35/10 = <em>3.5</em>
The distances of all of the numbers is <em>(absolute value of the difference between 3.5 and the number) </em>: <em>2.5, 4.5, 0.5, 2.5, 0.5, 0.5, 3.5, 1.5, 2.5, 0.5</em>
The mean of those is: <em>(2.5 + 4.5 + 0.5 + 2.5 + 0.5 + 0.5 + 3.5 + 1.5 + 2.5 + 0.5) /10</em> = 19/10 = 1.9
Answer:
2.50x+1.75y<=200
Step-by-step explanation:
Consider the data
Total amount of money available $200
Cost of cedar is $2.50 per feet. The the cost of pine $1.75 per feet
x=# of feet of cedar brought
y=# of feet of pine brought
As the cost of cedar wood is $2.50 and x is the # of feet of cedar brought, so the total cost of # of the wood is $2.50x
As the cost of pine is $1.75 and y is the # of feet of pine brought, so the total cost of # of the wood is $1.75y
The total cost of the # of cedar and pine woods together is
$2.50x+$1.75y
And the total amount available is 200, and it doesn't exceed so
$2.50x+$1.75y<= 200
The answer is b I just took the test
Answer:
1. (100-5) × (100+3) = 10000 + 300 - 500 - 15
=> 10300 - 515 = 9785
2. (500+1) × (500+2) = 250000 + 1000 + 500 + 2
=> 251502
