Answer:
discount = 9
new price = 36
Step-by-step explanation:
The discount is the price times the discount percent
45 * 20%
Change to decimal form
45*.20
9
The new price is the original price minus the discount
45-9 = 36
In order to draw the Box-whisker plot, we need to rewrite the data in increasing order.
42 43 47 48 51 52 56 56 58 60 62 64 65 66
Mean of the data = (42 + 43 + 47 + 48 + 51 + 52 + 56 + 56 + 58 + 60 + 62 + 64
+ 65 + 66) ÷ 14
Mean of the data = 770 ÷ 14
Mean of the data = 55
Median = (56 + 56) ÷ 2
Median = 112 ÷ 2
Median = 56
Lowest value = 42
Highest value = 66
Range = Highest value - Highest value
Range = 66 - 42
Range = 24
Lower Quartile = 25% of the data
Lower Quartile = 48
Upper Quartile = 75% of the data
Upper Quartile = 62
The answer is B (-8,6) this is because the magnitude is 2 so each tiny square is going to increase or decrease by intervals of 2 so if you count by two to the left you get 8 but since its going to the left that will be -8x and now you need to count up by 2's and that equals to 6y and you are at A on the graph so the answer will be (-8,6)
For this one use the slope formula, (y2-y1)/x2-x1)
Just to have them in one place, here are the ordered pairs
(-1,-2) (2,2)
You can do these in any order, here is how I did the problem:
(2--2)/2--1)
Your y intercepts are 2 and -2
The x are 2 and -1
Now reduce. Since you are subtracting a negative, it turns into a positive.
(2+2)/(2+1)
4/3
There is our slope: rise 4 run 3 or as a fraction 4/3.
Hope this helps!
