Answer:
x = 57
Step-by-step explanation:
Median is the number that is halfway mark. If we are given a data, first we need to arrange them in ascending order and take the middle value. That is called median.
If we have odd number of data, we can easily find the middle value.
For instance, 1, 2, 3, 4, 5 here the number of data = 5 which is odd number.
The middle number is 3.
Therefore, median is 3.
If we have even number of data, we have to take middle two values, add them then divide by 2.
In this case, we are given even number of data
30, 45, x, 100
4 data which is even number of data.
Median is given as 51, we need to find the value of x.
The middle two numbers are 45 and x, we have to add them and divide by 2
Median = [Given: median = 51]
51 =
Multiplying both sides by 2, we get
51*2 = 45 + x
102 = 45 + x
Subtract 45 in both sides, we get
102 - 45 = 45 -45 + x
x = 102 -45
x = 57
Answer: S = 3.5
Step-by-step explanation:
We know that congruent means that the sides are equal. Knowing this, we can make an equation to solve for.
We can 2s+11=8s-10.
We can then subtract 2s from both sides, getting 11=6s-10.
We can then add 10 to both sides, getting 21=6s.
Dividing both sides by 6, we get 3.5=S.

Answer:
308 mm
Step-by-step explanation:
The formula for circumference of a circle is
Where C is the circumference
is
, and
r is the radius (given as 49)
Putting them into the formula, we get:
Thus, circumference = 308 mm
Answer:308
Step-by-step explanation:
C=2(22/7)(49)
C=308
