Mean: average of all the numbers, in other words all the numbers added together then divide by the amount of numbers
Median:number with a value in the middle
Mode: most common number
Range: the difference in the numbers

Let x be the mean x=(0+3+3+4+4+4+6+8+8+9+10+10+
10+12+14)/15
=x=105/7
x=7

Median can be found by writing every number in order from least to greatest than finding the one in the middle
the median for this set of data is 8

Mode is 4 and 10 since they occur the most

And for range subtract the highest number by the lowest
14-0=0

Can u guys answer my question 13 and 14 pls

Alika [10]

Answer:

√2=1.414

then :√8 +2√32 +3√128+4√50

√8=√2³ =2√2

2√32=√2^5 = 4*2√2 = 8√2

3√128 = 3√2^6*2=8*3√2 =24√2

4√50 =4√5²*2= 20√2

add results : 2√2+8√2 +24√2+20√2=54√2

<h2>54√2=54×1.414=76.356 ( it is not in the options)</h2>

x=7-4√3

√x+ 1/√x

√(7-4√3) +1/√(7-4√3) =

(8-4√3)/√(7-4√3)

(8-6.93)/√(7-6.93) = 4 ( after rounded to the nearest whole number)

4 is your answer

The area of triangle ABC is _____.

Marizza181 [45]

I FOUND YOUR COMPLETE QUESTION IN OTHER SOURCES.
SEE ATTACHED IMAGE.
Using Heron's Formula we can find the area of the triangle.
A = root (s (s-a) * (s-b) * (s-c))
s = (a + b + c) / 2
Where,
s: semi-perimeter
a, b, c: sides of the triangle
Substituting values:
s = (15 + 16 + 20) / 2
s = 25.5
s = 26
The area will be:
A = root (26 * (26-15) * (26-16) * (26-20))
A = 130.9961832
A = 130 u ^ 2
Answer:
The area of triangle ABC is:
C.
130 u ^ 2
