b) All the figures are conrguent since only rigid motions were used.
Answer: y =7/4x
Step-by-step explanation:
The y-intercept is 0. To find the slope, do the change in y over the change in x. At the point on the graph, there is a slope of 14/8 = 7/4
To answer this question you will want to create an equation that you can use to find the final cost for any number of cards.
The first step is to find the relationship between the cost and the number of cards in the chart. To do this you need to find a unit price per card. To find this divide the price in any column by the number of cards you will get from the same row.
$13/20 = $0.65 per card.
Now you can set up the equation with the remaining information.
T = 1.077(0.65x) + 5.95
1.077 represents the total amount of the cards (1) plus sales tax (0.077)
x stands for the number of cards you will buy
one time charge of $5.95 is added on at the end
T = 1.077 (0.65 x 280) + 5.95
T = $201.96
So Mean Absolute Deviation or MAD for short is the Mean of how far each digit is from the Mean. So first find the mean, then for each number so let's say the mean is 3 and the numbers are 2, 4, 3. So 3-2=1, 4-3=1, 3-3=0. So you have 1, 1, 0. Find the mean of that 1+1+0=2/3 so the MAD is 2/3.
So just follow my steps
1. Find the mean
2. Find the difference from the mean of each number
3. Find the mean of step 2
4. Step 3 is your answer
Answer:
the answer is 1
Step-by-step explanation:
the equation is not factorable, making the only factor 1
