Answer:
mean=134.3
median=65.5
mode=60
Step-by-step explanation:
Mean is computing by adding the all data values and then divided by number of values
mean=sum of all values/number of values
There are 20 data values.
mean=(88+50+66+60+360+55+500+71+41+350+60+50+250+45+45+125+235+65+60+110)/20
mean=2686/20
mean=134.3
For calculating median we arrange the data in ascending order
41 45 45 50 50 55 60 60 60 65 66 71 88 110 125 235 250 350 360 500
n/2=20/2=10 is an integer
So, the median is the average of n/2 and (n/2)+1 value
The median is average of 10th and 11th value
median=(65+66)/2
median=65.5
Mode is the most repeated value and we see that number of times the values are repeated are
45= 2 times
50= 2 times
60= 3 times
Thus, the most repeated value is 60 and it is the mode of data.
Mode=60
Answer:
(-3,-4)
Step-by-step explanation:
The vertex is the minimum or maximum or a parabola.
This is an upward opening parabola, so it has a minimum.
The minimum is (-3,-4)
Answer:
Step-by-step explanation:
Complex numbers are the numbers represented by the expression = a + bi
Here a = real part of the number
bi = imaginary part
a and b are the real numbers.
[Since, 
]
Therefore, its a non real complex number.
2 - 
= 
= 
= 
This number is a Non real complex number.
= 18i
It's a non real complex number.
3 + 2i
It's a non real complex number.
-289
It's a purely real number.
= 4 + 32
= 36
It's a purely real number.
