Answer:
360
Step-by-step explanation:
Multiply them all
The answer is 80 :)
Given that normally distributed data set has a mean of 55 and 99.7% of data fall between 47.5 and 62.5.
Let s be the standard deviation of data set.
Since 99.7% data fall within 3 standard deviations of mean, z-value for 47.5 and 62.5 has an absolute value of 3.
That is |z|=3
But z=
Let us plugin x=47.5 and mean =55 and equate it to 3.
That is
Since x is always positive ( being standard deviation),
Hence
We will get same value with 62.5 as well.
Hence standard deviation of data set is 2.5.
What is the domain of the given function?
{(3,-2), (6, 1), (-1, 4), (5,9), (-4, 0);
O {x | x= -4,-1, 3, 5, 6}
O {yl y = -2,0, 1,4,9}
O {x|x = -4,-2, -1,0, 1, 3, 4, 5, 6, 9}
O y y = 4,-2, -1, 0, 1, 3, 4, 5, 6, 9}
