Step-by-step explanation:
To multiply radicals with the same root, you just need to multiply the numbers or expressions inside the root retaining the same root and then simplify the result.
In this case:
Answer:
IQR = 6
Step-by-step explanation:
Given:
The given set of data is:
40 41 42 43 44 45 46 47 48 49 50
Number of terms,
Therefore, the median is given as term which is the sixth term. Median = 45
(40 41 42 43 44) <u>45</u> (46 47 48 49 50 )
Now, we find the median of the lower half () and upper half (
)of the data that are before and after the median.
The lower half of the data has the values 40 41 <u>42</u> 43 44.
Number of terms are 5. So, median is the third term which is,
The upper half of the data has the values 46 47 <u>48</u> 49 50.
Number of terms are 5. So, median is the third term which is,
Now, IQR is given as the difference of upper half median and lower half median.
Answer:
x=7
Step -by -step explanation:
Given that,
We first simplify the left hand side of the equation to obtain
we then cross multiply to get
We divide both sides of the equation by the coefficient of x (i.e 6) to get the value of x.
Therefore,
