4 pens
Step-by-step explanation:
better value
The answer is 2,268 because 378 times 6 is 2,268
Y = mx + b
slope(m) = -3/8
(5,-4)...x = 5 and y = -4
now we sub and find b, the y int
-4 = -3/8(5) + b
-4 = -15/8 + b
-4 + 15/8 = b
-32/8 + 15/8 = b
-17/8 = b
y = -3/8x - 17/8.....add 3/8x to both sides
3/8x + y = -17/8...multiply everything by 8
3x + 8y = - 17 <=== standard form
To find the Mean you have to add all the numbers from the data set,
Next you divide the sum by the amount of numbers in the set,
Final Answer: 52
Well 4/4 is equivalent to 1 so do 4/4+3/4
your answer would be 7/4
