Answer:
No it is not a good sample because if a person works full time then he would be at work around that time.
Step-by-step explanation:
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.
Answer:
use the distance Formula D=sqrt of {(x1-x2)^2+(y1-y2)^2}
Step-by-step explanation:
So(-5--9)^2 + (-5- -2)^2 =
(4)^2 + (-3)^2 =
16 + 9 = 25
and the square root of 25 is 5.
5 is the answer
16 tiles will fit end to end on a 4 foot wall.
In unitary method we will learn how to find the value of a unit from the value of a multiple and the value of a multiple from the value of a unit.
When we go to the market to buy any article, we ask the shopkeeper to tell the price of the article. This is called unit price. We calculate the price of number of articles, we want to buy, with the help of this unit price. Sometimes, we calculate unit price when the price of a multiple is given.
1 tile in 1/4 foot
So in 4 foot wall the number of tiles = 4/(1/4) = 16 tiles.
Thus 16 tiles will fit end to end on a 4 foot wall.
