Your answer here is t = -20
-8 = 2/5t
Equation
2/5 = 0.4
2 divided by 5 is 0.4
-8 / 0.4 = -20
Divide -8 by 0.4 which is -20
Question 4: a ray is formed by an endpoint and a line starting at the endpoint and going on forever in one direction
We cannot see angle MBW to be able to classify it
San Antonio to El Paso
= 558 mi
--------------------
Lubblock to Abilene 165 mi
165 / 55 = 3 hours
you must be there in 2 1/2 hours
so
answer is No
B) is correct; on average, each bag of candy has a weight that is 2.6 oz different than the mean weight of 5 oz.
To find the mean absolute deviation, we first find the mean. Find the sum of the data points and divide by the number of data points (without the outlier, 21, in it):
(10+3+7+3+4+6+10+1+2+4)/10 = 50/10 = 5
Now we find the difference between each data point and the mean, take its absolute value, and find their sum:
|10-5|+|3-5|+|7-5|+|3-5|+|4-5|+|6-5|+|10-5|+|1-5|+|2-5|+|4-5| =
5+2+2+2+1+1+5+4+3+1 = 26
We now divide this by the number of data points:
26/10 = 2.6
This is a measure of how much each bag of candy varies from the mean.
