Explanation:
The original set
{78, 55, 22, 16, 84, 75, 33, 69, 58, 59}
sorts to
{16, 22, 33, 55, 58, 59, 69, 75, 78, 84}
The min and max are 16 and 84 respectively
Midrange = (min + max)/2 = (16+84)/2 = 50
Answer:
Below
I hope its not too complicated
Step-by-step explanation:
The answer to 75 - ( 8 + 45 ÷ 3 ) × 2= 29
The standard deviation will be: 2.1
We know that standard deviation is basically the square root of variance.
Using the formula to calculate the standard deviation
As
so the standard deviation can be calculated as:
standard deviation
Therefore, the standard deviation will be: 2.1
Answer:7
This question is on the ukmt junior maths challenge which I'm doing now, out of the options given I got 7, because 2+4+6+5+(5×20)+(7×7)= 166, (then dividing that by the number of numbers to get the mean) so 166÷31= 5.354.....
Also the 3 has a recurring symbol above it
The 7 is times seven so uh yeah<3
I am very confused by this
so I'ma say yes
