Answer:
44.
Step-by-step explanation:
Let, x= white marbles
and y= yellow marbles
Now, according to the first condition
x + y = 58 … (1)
According to the second condition,
x= 3y+2
Or, 3y - x = -2 … (2)
Adding (1) and (2)
4y= 56
Or, y= 14
... (3)
Now, putting (3) in (1)
x = 44
Therefore there are 44 White marbles and 14 yellow marbles.
Answer:
2.64
Step-by-step explanation:
The z score is calculated as
z=(x-mean)/Sd
The mean of scores of statistics exam=μ=99
The standard deviation of scores of statistics exam=σ=11
Individual's score in statistics exam=x=128
z=128-99/11=29/11=2.64
Hence, the z score of individual score is 2.64.
