Answer:
4 2/7
Step-by-step explanation:
It is convenient to let a spreadsheet or graphing calculator do the tedious math for you. (See the attachment.)
_____
The sum of the numbers is 56, so their average is 56/7 = 8. Then the absolute deviations from average are ...
... 8, 5, 2, 1, 3, 5, 6
and the total of these is 30. The mean absolute deviation is this sum divided by the number of numbers, 7, so is ...
... 30/7 = 4 2/7
_____
<em>More about Absolute Deviation from Average</em>
"Absolute" here refers to the absolute value function, which drops the sign of a negative number. The absolute deviation of the data value 0 is ...
... |0 - 8| = |-8| = 8
For 3, it is ...
... |3 - 8| = |-5| = 5
A) 500(.12)= 60 ants per week. Therefore, (10 weeks)(60 ants) = 600ants + 500 ants = 1,100 ants
B) (20 weeks)(60 ants)= 1,200 ants + 500 ants = 1,700 ants
Answer:
<em><u>It will cost $2.52 shipping fee to ship an item that costs $56</u></em>
Step-by-step explanation:
You can get the answer by multiplying 4.5% by $56.
Before you multiply , you need to convert the percent to a decimal which would 0.045.
C = 0.045(56) = 2.52
Answer:
"Members of a population are organized in clusters, each of which is representative of the population, and then whole clusters are randomly selected to make up the sample"
Step-by-step explanation:
In cluster random sampling, "the population is divided, usually geographically, into groups that generally have the same size. A certain number of groups are randomly chosen, and every individual in the chosen groups are chosen for the sample."
In accord with this logic, the second choice, "Members of a population are organized in clusters, each of which is representative of the population, and then whole clusters are randomly selected to make up the sample" seems to be correct.
NOTE: This may not be the correct answer. I am simply basing my answer on the definition I have learnt.
Make sure your calculator is set to DEGREES and not RADIANS when performing your sinθ calculation.
sin(10) = -0.54402
sin(10°) = 0.17365
You could also try using trig tables if you're unsure how to do this.
So:
2500sin(10°) = 434 lb
