Answer:
for the first one, x + 3 * y = 5
and the second equation, x - y = 5
Step-by-step explanation:
the sum of two numbers means for example the sum of 5 and 8 is 13, so as an equation that is 5 + 8 = 13
the difference is the same thing as the sum but it's subtraction.
and then times is just multiplication.
Answer:
the answer is 1.16 shirts
Step-by-step explanation:
the mean absolute deviation is found by finding the average of the difference between each data point and the mean of the data.
1st...find the mean of the data by adding all the numbers according to the data plotted and dividing the by the numbers listed; which in this case is 10
1 +2+ 2+ 3+ 3+ 3+ 4+ 4+ 5+ 6 = 3.3
mean is 3.3
then find the difference between the mean and each data point
Data Point = 1 2 2 3 3 3 4 4 5 6
Difference from mean = 2.3 1.3 1.3 0.3 0.3 0.3 0.7 0.7 1.7 2.7
Find the average of these differences by adding the (differences from Mean) by 10
<u>2.3 + 1.3 + 1.3 + 0.3 + 0.3 + 0.3 + 0.7 + 0.7 + 1.7 + 2.7</u>
10
the mean absolute deviations is 1.16 shirts
Answer:
x° =125° y°= 125°
Step-by-step explanation:
55° + x° = 180° because they are complementry angles
solve for x by subtracting 55° from both sides
x° = 125°
x° and y° is equal because they are vertical angles
2.8 because 14/5 equals 2 80/100.
Answer:
80°
Step-by-step explanation:
because a straight parallel line is 180°
