Okay so the range is the largest number - the smallest number.
So 25 - 11 = 14
The Absolute Mean Deviation is going to be a bit harder to explain, just go with it.
So we first calculate the mean.
119 ÷ 7 = 17
Now we calculate the distance each value is from 17. (SEE ATTACHMENT)
What happens next is that you take those values that are the distance from 17 and you add those up and calculate the mean of that.
28 ÷ 7 = 4
The Absolute Mean Deviation is 4.
I'll figure out the bottom in a minute. But this is all I got for you so far.
Answer:
-Noah could buy 10 tacos for $15.
-Jada's tacos were not the same price as Noah's tacos.
Step-by-step explanation:
You can use a rule of three to find the amount of tacos that Noah could buy with $15:
$6 → 4
$15 → x
x=(15*4)/6=10
At this rate, Noah could buy 10 tacos for $15.
Now, to find out if Jada's tacos were the same price as Noah's tacos, you have to find the price per taco in each case by dividing the amount paid by the number of tacos bought:
Noah: 15/10=1.5
Jada: 72/50=1.44
According to this, Jada's tacos were not the same price as Noah's tacos.
Answer:
Find the median value for the dataset. Find the values of the lower and upper quartiles. Find the value of the interquartile range (IQR). Identify any outliers in the dataset. Use the criterion that a value is an outlier if it is either more than 1.5 x IQR above
Y=-3x+8
when x=-2:
y=-3(-2)+8
y=6+8
y=14
when x=0
y=-3(0)+8
y=0+8
y=8
when x=2
y=-3(2)+8
y=-6+8
y=2
The value of k is 60
131 - 11 = 120
120/2 = 60
hope this helped !
