Step-by-step explanation:
To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean
If you were on a number line you go over 10 numbers to the left. Therefore, you will pass all of these numbers...
-7,-6,-5,-4,-3,-2,-1,0,1,2. Your answer will be 2.
Answer:
X = 40°
Y = 78°
Step-by-step explanation:
Since the two angles at the bottom are parallel as it is shown that the triangle is an isosceles triangle (which means 2 angles in a triangle are the same while the one other is different)
51 - 11 = 40 (X)
Since we found out 2 angles in the triangle...
51 + 51 = 102
180 - 102 = 78 (Y)
Answer:
To form 100 lb of the mixture we need 25 lbs of $9 coffee beans and 75 lbs of $15 coffee beans.
Step-by-step explanation:
Let <em>x</em> be the number of pounds of $9 coffee beans and y be the number of pounds of $15 coffee beans.
We know that the mixture must weigh 100 lb
and the total cost per pound is given by
Now, we can solve the system of equations
Isolate x for
Substitute into the second equation
Isolate y
For substitute y = 75
To form 100 lb of the mixture we need 25 lbs of $9 coffee beans and 75 lbs of $15 coffee beans.
