Answer: a. Mean = 0.696364
b. Median = 0.64
c. Midrange = 0.895
d. There is no Mode
e. 2. The maximun data value is the most relevant statistic, because it is closest to the limit of 1.6W/kg and that cell should be avoided.
Step-by-step explanation:
a) Mean is an average number of the data set, calculated by the sum of all the value divided by the quantity of the set:
mean =
mean = 0.696364
b) Median is the middle number in the list of numbers. In this case, since there are 11 elements in the set, the middle number is:
sorted numbers of the data set:
0.22 0.24 0.29 0.35 0.54 0.64 0.75 0.81 1.02 1.23 1.57
median = 0.64
c) Midrange is another type of average number. It is calculated as:
midrange =
midrange =
midrange = 0.895
d) Mode is the number that appears most often in the list of numbers. For this data set, each number appears only one time, so there is no mode.
Mode = 0
e) According to the question, cell phone radiation is dangerous when it is higher than 1.6W/kg. The cell phone with the maximum data value (1.57 W/kg) should be avoided, since it is too close to the limit described.
So, the measures of center are not the most important statistic to be observed but the maximum data value.
The value of y is 40 degree , Option B is the correct answer.
<h3>What is Angle Sum Property ?</h3>According to angle sum property, the sum of all angles of a triangle is equal to 180 degree.
It is given in the question a triangle , here
the angles given are 2y , y+10 , 50 degree
From the property ,
2y + y + 10 +50 = 180
3y +60 = 180
3y = 120
y = 40 degree
Therefore The value of y is 40 degree , Option B is the correct answer.

<em><u>Solution:</u></em>
Given that we have to find the product and write it in lowest term
Given expression is:
Let us first find common factors of numerator and denominator so, thet simplification becomes easier
Substituting these in above expression, we get
Cancel the common factors in numerator and denominator
In decimal form, we get
Thus the product of given expression is
