Answer:
F an amazing result.
Step-by-step explanation:
I'm sure I didn't do this the way it was intended, but I think I got it right.
First of all, we have to agree that CAB is marked as a right angle. If you do not agree, leave a note.
Step One
Find the length of AC
BC = 16
AB = 10
AC^2 = BC^2 - AB^2
AC^2 = 16^2 - 10^2
AC^2 = 256 - 100
AC^2 = 156
AC = SQRT(156)
AC = SQRT(4*13 * 3)
AC = 2 SQRT(13)
Step Two
Find the height (AD)
There are two ways to find the area of the large triangle ABC
Area = 1/2 * 16 * AD and
Area = 1/2 AC * 10 The two legs.
Since these areas must be equal, equate them. You are looking for AD
16 * AD = 2*sqrt(39) * 10 Divide by 16
AD = 20* sqrt(39)/16
AD = 5 * sqrt(39) / 4
Step 3
Find x or DB
DB^2 = 10^2 - [(5 *sqrt(39)/4]^2
DB^2 = 100 - 25*39/16
DB^2 = 100 - 60.9375
DB^2 = 39.0625
DB = SQRT(39.0625)
DB = 6 1/4
6 1/4 is the same thing as 25/6 which is F
The standard deviation for the cost of mobile cell phones is 10.925.
Given
Mobile cell phone cost Number of students
10-19.99 7
20-29.99 20
30-39.99 28
40-49.99 12
50-59.99 7
We have to calculate the standard deviation of the given data.
Standard deviation is a measure which measures the variation in te values of data sets.
We know that the formula of calculating standard deviation is as under:
Standard deviation=
/
Mean=33.91392 (calculated in figure)
∑f
=8713.514 (calculated in image)
∑f-1=74-1=73
We have to now just put the values and find the value of standard deviation.
Standard deviation=
=
=10.925
Hence the standard deviation of mobile cost is 10.925.

Answer:
Step-by-step explanation:
75 = 5 *5* 3
29 is a prime number = 29*1
168 = 2*2*2*3*7
Let's work backwards. The 2001 team won 29 games. They won 2 more games than the 2000s team, 29-2=27. The 200s team won 27 games. The 2000 team won 27 games, and they won 3 more than the 1999 team. 27-3 = 24.
The 1999 team won 24 games.
I would like to say that it was an absolute honor helping you!!
